For model 5, the tip of the blade travels 0.18 mile per revolution. What is the approximate speed, in revolutions per minute, for model 5?

Answers

Answer:

19 revolutions per minute, for model 5.

Step-by-step explanation:

Consider the model shown below:

From the table:

The blade length for model 5 is 148 feet

Also the maximum blade tip speed is 200 miles per hour.

It is given that the tip of the blade travels 0.18 mile per revolution.

To find the number of revolution per hour simply divide the maximum speed of the blade with the revolution.

Number of revolutions per hour = [tex]\frac{200}{0.18}=1111.111[/tex]

We need to find the speed, in revolutions per minute, so divide the obtained revolution per hour with 60.

[tex]\frac{1111.11}{60} =18.52\approx19[/tex]

Hence, 19 revolutions per minute, for model 5.

Final answer:

To determine the speed in revolutions per minute for model 5, we need to know how far the blade tip travels in one minute. This would be divided by 0.18 miles, the distance per revolution, to find the RPM. Without the distance traveled in one minute, we cannot complete the calculation.

Explanation:

To calculate the approximate speed in revolutions per minute for model 5, where the tip of the blade travels 0.18 miles per revolution, we need to find how many revolutions it would complete in one minute. Assuming the tip travels at a constant speed, you would divide the distance it covers in one minute by the distance per revolution.

First, determine the distance traveled by the blade tip in one minute. Since no speed is given for one minute in the question, we cannot provide a direct answer; more information would be needed, such as the distance the blade tip travels in a given time frame. However, if we had information like this, we could proceed with a calculation:

Let's say the tip travels X miles in one minute. You would then divide X by 0.18 miles to find the number of revolutions per minute:

Revolutions per minute (RPM) = Distance in miles per minute / Distance per revolution

RPM = X miles / 0.18 mile

For example, if the tip travels 1.8 miles in one minute, then:

RPM = 1.8 miles / 0.18 mile = 10 RPM

Leiff goes online to buy a new video game. He finds a site that currently has a promotion of 15% off on all orders over $50. Leiff decides to buy his video game, with a price tag of $128, at this site because he knows that he will get the 15% discount when he checks out. Leiff pays 5.3% sales tax on the discounted price and pays a shipping fee of $4.75. What is the total of Leiff’s online purchase?

Answers

Answer:

$119.32

Step-by-step explanation:

Leiff decides to buy his video game, with a price tag of $128, at this site

he will get the 15% discount when he checks out.

100-15= 85%

Discounted price=85% of 128 is [tex]0.85 \cdot 128=108.8[/tex]

Leiff pays 5.3% sales tax on the discounted price

5.3% is 0.053

sales tax amount=0.053 times 108.8=5.7664

So we add the sales tax amount and shipping fee

[tex]108.8+5.7664+4.75=119.32[/tex]

So $119.32 is the total amount

The total of Leiff’s online purchase is $119.31.

To calculate the total of Leiff's online purchase, we need to first calculate the discount on the video game.

The discount is calculated by multiplying the original price of the video game by the discount rate.

Discount = $128 * 15%

= $19.20

The discounted price of the video game is the original price minus the discount.

Discounted price = $128 - $19.20

= $108.80

The sales tax is calculated by multiplying the discounted price of the video game by the sales tax rate.

Sales tax = $108.80 * 5.3%

= $5.76

The total cost of the video game, including the discount and sales tax, is:

Total cost = $108.80 + $5.76

= $114.56

The total cost of Leiff's online purchase is the cost of the video game plus the shipping fee.

Total cost = $114.56 + $4.75

= $119.31

Therefore, the answer is $119.31.

If stewart and patrick can finish a science project together in 20 minutes, and Patrick works four times as quickly as Stewart, how long would it take Patrick to complete the project alone?

Answers

Answer:

It would take 25 minutes for Patrick to complete the project alone.

Step-by-step explanation:

They did the project in 20 minutes, that is, 100% of the project, so:

[tex]x + y = 1[/tex]

In which x is the percentage that Patrick worked and y is the percentage that Stewart worked.

Patrick works four times as quickly as Stewart, so x = 4y.

So

[tex]x + y = 1[/tex]

[tex]4y + y = 1[/tex]

[tex]5y = 1[/tex]

[tex]y = 0.2[/tex]

-----------

[tex]x = 4y = 4*0.2 = 0.8[/tex]

Patrick did 80% of the project in 20 minutes. We can solve this problem by a simple rule of three, in which the time it would take for him to complete the project alone is 100%. So

20 minutes - 0.8

x minutes - 1

[tex]0.8x = 20[/tex]

[tex]x = 25[/tex]

It would take 25 minutes for Patrick to complete the project alone.

Final answer:

Patrick, who works four times as quickly as Stewart, would take 25 minutes to complete the project alone.

Explanation:

This question is about rates and can be solved using algebra. Let's denote the rate at which Stewart can do the work as S and the rate at which Patrick does the work as P. Since Patrick works four times as quickly as Stewart, P=4S. The rate at which they work together is S+P. According to the question, together they can complete the job in 20 minutes, so their combined rate is 1 job per 20 minutes or 1/20. Therefore, S + P = 1/20.

Substitute P=4S into the equation, we get S + 4S = 1/20, which simplifies to 5S = 1/20. Solve this equation, we find that S = 1/100. So Stewart alone would finish the job in 100 minutes. Since Patrick is four times faster, Patrick alone would complete it in 100/4 = 25 minutes.

A trough is 8 feet long and has perpendicular cross section in the shape of an isosceles triangle (point down) with base 1 foot and height 2 feet. The trough is being filled with water at a rate of 1 cubic foot every 5 minutes. How fast is the water level rising whenthe water is 1/2 foot deep?

Answers

Answer:

Dh/dt  = 0.082 ft/min

Step-by-step explanation:

As a perpendicular cross section of the trough is in the shape of an isosceles triangle the trough has a circular cone shape wit base of  1 feet and height     h = 2 feet.

The volume of a circular cone is:

V(c)  = 1/3 * π*r²*h

Then differentiating on both sides of the equation we get:

DV(c)/dt   = 1/3* π*r² * Dh/dt   (1)

We know that DV(c) / dt   is  1 ft³ / 5 min      or     1/5  ft³/min

and  we are were asked how fast is the water rising when the water is 1/2 foot deep. We need to know what is the value of r at that moment

By proportion we know

r/h  ( at the top of the cone  0,5/ 2)   is equal to  r/0.5  when water is 1/2 foot deep

Then      r/h   =   0,5/2   =  r/0.5

r  =  (0,5)*( 0.5) / 2        ⇒   r  =  0,125 ft

Then in equation (1) we got

(1/5) / 1/3* π*r² =  Dh/dt

Dh/dt  = 1/ 5*0.01635

Dh/dt  = 0.082 ft/min

Hence, [tex]f(f^{[2004]}(x))=\frac{1}{2}[/tex].

Assume [tex]y=f^{[2004]}(x)[/tex].

Hence, [tex]f(y)=\frac{1}{2}[/tex] or [tex]y=\frac{1}{4}[/tex] or [tex]y=\frac{3}{4}[/tex].

So we can conclude that [tex]f^{[2004]}(x)=\frac{1}{4}[/tex] or [tex]f^{[2004]}(x)=\frac{3}{4}[/tex].

So we can find [tex]f(f^{[2003]}(x))=\frac{1}{4}[/tex] orf(f^{[2003]}(x))=\frac{3}{4}.

Assume [tex]z=f^{[2003]}(x)[/tex].

[tex]f^{-1}(x)=f(x)[/tex]

In this problem the graph of the inverse function is the same that the graph of the original function

Final answer:

Graphing the inverse of a function is achieved by flipping the graph over the line y = x. In science, graphs of inversely proportional variables like P and V form a hyperbola, but these can be 'linearized' for clarity and accuracy. Often, a regression analysis is utilized to find the best fitting line within a set of data plots.

Explanation:

To graph the inverse of a function, you observe the function as a set of points in a 2D space (on a graph) and flip each point over the line y = x. This results in a new function, which is the inverse. When it comes to more specific functions like pressure and volume relationships, this is shown when plotting the inverse of the pressure (P^-1) versus the volume (V), or the inverse of volume (V^-1) versus the pressure (P).

Scientists often linearize data when graphs have curved lines because they're difficult to read accurately at low or high values. If you plot P (pressure) versus V (volume), you will get a hyperbola. This kind of function can be 'linearized' to make it easier to understand and interpret.

Finally, in many cases, such as plotting data points of inflation rate versus unemployment rate, the resulting graph can be analysed using a statistical process called regression. This helps to find the best fitting line for the set of data plots, which can often not perfectly fit the line.

The major arc is DE, 142 degrees.

The minor arc is AC, 48 degrees.

The two secants intersect outside the circle and creates a vertex angle, Angle B. The theorem tells us that the measure of that vertex angle would be ONE HALF of the difference of the two intercepted arcs. So, we have:

For Size B - [tex]16\frac{1}{2}[/tex] or [tex]\frac{33}{2}[/tex] ounce can costs $6.49

Per ounce cost = [tex]\frac{6.49}{\frac{33}{2}}[/tex]

= 0.39

For size C - [tex]24\frac{3}{4}[/tex] ounce or [tex]\frac{99}{4}[/tex] ounce can costs $8.49

Per ounce cost = [tex]\frac{8.49}{\frac{99}{4}}[/tex]

Darwin used this to illustrate that as food supplies increase, populations increase.

Answers

Answer:

C. Darwin realized this also applied to plant and animal populations, and this struggle for existence resulted in an opportunity for natural selection to act on differences within populations.

Step-by-step explanation:

Thomas Malthus in his Malthusian theory of population concluded that since population increases geometrically and  resources only increase arithmetically, there will reach a point in time when the resources will be not be able to sufficiently cater for the population.

The Charles Darwin theory of Evolution is based on five key observations and conclusions drawn from them. These observations and inferences are summarized as:

Species are more fertile. They birth more offspring than can grow to adulthood. Populations remain fairly stable with miniscule fluctuations. Food resources are limited, but are relatively constant most of the time.

Based off these observations, it is seen that there will be a struggle amongst the members of the specie for the limited resources.

In sexually reproducing species, generally no two individuals are identical. Variation is rampant.Much of this variation is heritable.

From the last two observations, the species that survive then pass on their traits to their offspring and the cycle repeats itself with each subsequent generation being better evolved than the previous ones.

Thus, Darwin discovered that the Malthusian theory of population also applies to plant and animal populations where scarcity of resources gives room for natural selection to take place due to the variation within populations.

In the xy-coordinate plane, line l is perpendicular to the y-axis and passes through the point (5, -3).Which of the following is an equation of line l?A. x = 0B. x = 5C. y = −3D. y + 3 = x + 5E. y − 3 = x + 5

Answers

Answer:

C. y = -3

Step-by-step explanation:

Line L is perpendicular to the y-axis, so line L is just a straight horizontally line going from left to right.

This mean that the x-coordinate they gave us is irrelevant since our flat line is going to pass through all possible x-values. The only thing we need to focus on the the y-value.

So we know that the line passes through (__, -3)

the equation y = -3 gives us a horizontal line that passes through (__, -3).

Therefore answer is C.

Answer A and B are wrong because they gave us vertical lines, we want horizontal lines. D and E are wrong because those are diagonal lines, we want flat horizontal lines.

y + y + x = 50

Solve for one of the side. I solved for x because it's easier to work with and substitute later. I got x = 50 - 2y.

Now I solve for area. Area of a rectangle is Length * Width.

A = LW

I used x and y for my sides so my area is this instead:

A = yx

Substitute in x.

A = y(50 - 2y)

A = 50y - 2y²

Area must be a minimum of 300ft², so

50y - 2y² ≥ 300

50y - 2y² - 300 ≥ 0

replace y with L because that's what they used in the answer choice

-2L² + 50L − 300 ≥ 0

Answer:

-2l^2+50l-300 ≥ 0

l(50 − 2l) ≥ 300

(l − 15)(l − 10) ≤ 0

There are 70 students in a school band. 40%are sixth graders,20% are seventh graders and the rest are eighth graders.How many sixth graders are there.

Answers

Answer:the number of sixth graders is 28

Step-by-step explanation:

Total number of students in the school band is 70. 40% are sixth graders. 20% are seventh graders and the rest are eighth graders. This means that the percentage of eighth graders is 100 - (40+20) = 100 - 60 = 40%

This means that the number of sixth graders would be 40% of the total number of students in the school band. It becomes

40/100 × 70 = 0.4×70 = 28

involving a carnival fishpond. Assume that the pond contains 100 fish: 78 purple, 21 blue, and 1 silver. A contestant pays $0.65 to randomly catch one fish and receives $0.40 if the fish is purple, $0.80 if the fish is blue, and $13.00 if the fish is silver. How much (on average) does the carnival gain on each play?

Answers

Answer:

On average the carnival gain on each play

= 0.04 dollars

Step-by-step explanation:

Given that a pond contains 100 fish: 78 purple, 21 blue, and 1 silver.

Fish            Purple     Blue          Silver    total

   

Frequency  78               21                 1    100

Prob          0.78      0.21             0.01      1

Revenue           0.4                0.8            13  

game fee 0.65        0.65            0.65  

Net revenue -0.25      0.15            12.35    

   

Net Rev*Prob -0.195      0.0315   0.1235   -0.04

Thus we get per player expected net revenue is -0.04

This would be gain for Carnival

Hence On average the carnival gain on each play

= 0.04 dollars

Final answer:

To calculate the carnival's average gain per play, determine the expected payoff for each fish type, subtract the cost to play, and sum these amounts. The carnival gains an average of $0.61 per play.

Explanation:

The student's question involves calculating the average gain for a carnival on each play of a carnival fishpond game. To find this, we need to determine what the carnival earns on average based on the probabilities of catching each type of fish (purple, blue, or silver) and the payoff for each.

Let's calculate the expected profit (gain) per play for the carnival. The probability and payoff for each type of fish are:

Purple fish: Probability = 78/100, Payoff = $0.40

Blue fish: Probability = 21/100, Payoff = $0.80

Silver fish: Probability = 1/100, Payoff = $13.00

The expected payoffs for the carnival from catching each type of fish are:

Purple: 78/100 * $0.40

Blue: 21/100 * $0.80

Silver: 1/100 * $13.00

Subtract the contestant's cost ($0.65) from each expected payoff to find the expected gain. Then, sum these expected gains to find the overall average gain for the carnival.

The carnival's expected gain is:

Expected Gain per Play = (78/100 * $0.40) + (21/100 * $0.80) + (1/100 * $13.00) - $0.65

Calculating:

Expected Gain per Play = ($0.3120) + ($0.1680) + ($0.1300) - $0.65

Expected Gain per Play = $0.61

This calculation shows that on average, the carnival gains $0.61 for each play of the fishpond game.

Jakes truck can tow a max weight of 5,000 pounds. What is the max number of horses he can take in his trailer at one time without going over the max weight his truck can tow

Answers

Answer:

He can take 5 Horses at max in his trailer at one time without going over the max weight his truck can tow. (Assuming the average weight of one horse to be equal to 1000 pounds)

Step-by-step explanation:

The no. of horses that can be carried by the truck can be found by simply dividing the maximum weight, that the truck can tow by the weight of a horse.

Max. No of Horses = (Max weight truck can tow)/(Average weight of one    horse)

The weight of a horse is not given in the question .Thus, we assume the average weight of one horse, to be equal to 1000 pounds, we get:

Max. No of Horses = 5000 pounds/ 1000 pounds

Max. No of Horses = 5

Find the area of the largest isosceles triangle that can be inscribed in a circle of radius r

Answers

Answer:

  (3/4)(√3)r²

Step-by-step explanation:

The largest such triangle is an equilateral triangle. It will have a side length of r√3. The area can be found a number of ways, one of which is to use the formula for the area of an equilateral triangle of side length s:

  A = s²·(√3)/4

Using s=r√3, we get ...

  A = (3/4)(√3)r²

Sally is interested in taking a job in a city which she's not familier with the cost of living. She is especially concerned about the cost of housing and is interested in the average cost of a three bedroom home. Which of the following averages will be most influenced by three bedroom homes owned by millionaires?
a.mode
b.median
c.mean
d.none of the above

Answers

She wants to find the mean. A mean is the average

Answer:

c.Mean

Step-by-step explanation:

We have been given that the Sally is interested in taking a job in a city in which she's not familiar with the cost of living. She is especially concerned about the cost of housing and is interested in the average cost of a three bedroom home.

We know that in a normal distribution all central tendencies (mean, mode, median) are equal.

When a very large or very small valued data point is added to data set, mean is mostly affected by that outlier.

We know that mode of a data set is the point that appears at-most in the data set, so outliers doesn't affect mode.

Median of a data set is less affected by outliers.

The price of the three bedroom homes owned by millionaires will be greater than prices of houses owned by people in the neighborhood.

Therefore, mean will be most influenced by three bedroom homes owned by millionaires.

Jade took a math test with 20 questions is worth an equal number of points. The test is worth 100 points in total. Write an equation that can be used to calculate jade's score based on the number of questions she got right on the test.

Answers

Answer:

[tex]Jade's\,score=5*right\,answers[/tex]

Step-by-step explanation:

Because all the questions have the same point, we can find the weight (value) of each question dividing the total points by the total number of answers questions:

[tex]\frac{100}{20}= 5[/tex]

Now with the weight of each question the only thing we should to do is to multiply it by the number of the questions she got right:

[tex]Jade's\,score=5*right\,answers[/tex]

Let check if our equation works, if Jade got all the answers right, we expect she got a 100 score. Let verify on the equation

[tex]Jade's\,score=5*(20)=100[/tex], that's what we expected

If she got 10 right answers, we expect 50 score and if she got 0 right answers, we expect 0 score, let check again:

[tex]Jade's\,score=5*(10)=50[/tex]

[tex]Jade's\,score=5*(0)=0[/tex]

Again, we obtain the expected scores, so we can conclude our equation works.

 

Final answer:

To find Jade's score on the math test, calculate the points per question by dividing the total points (100) by the number of questions (20). Each question is worth 5 points. Jade's score is the number of questions she got right multiplied by 5 points.

Explanation:

To calculate Jade's score on a math test with 20 questions that is worth a total of 100 points, we can start by finding out how many points each correct answer is worth. Since the total points are evenly distributed among the questions, we divide the total points by the number of questions.

Each question is worth 5 points (100 points total ÷ 20 questions).

Let x represent the number of questions Jade got right. The equation to calculate Jade's score is then:

Score = 5 × x

To find Jade's score, we simply multiply the number of questions she got right by 5. For example, if Jade answered 16 questions correctly, her score would be 80 points (5 points/question × 16 questions).
