Answers

I believe the family budget to make a one- way trip will be $140 because each gallon is $3.50. You need 20 gallons to get there which is $70. You need 20 gallons to get back which is another $70. You add both and is $140. Hope this helped.
Final answer:

The cost of one gallon of gas is $3.50 (calculated by dividing $10.50 by 3). Therefore, to find out the budget needed for the one-way trip to border=0 cell spacing=0 cellpadding=0 the grandmother's house, multiply the cost per gallon by the number of gallons needed, getting: 20 gallons * $3.50/gallon = $70.

Explanation:Solution:

The first step is to identify the cost per gallon of gas. From the problem, we know that three gallons of gas cost $10.50. So, we can find out how much one gallon of gas costs by dividing $10.50 by 3, which is $3.50 per gallon.

The top three corn producers in the world​ - country​ A, country​ B, and country C​ - grew a total of about 664 million metric tons​ (MT) of corn in 2014. The country A produced 82 million MT more than the combined production of country B and country C. Country B produced 177 million MT more than country C. Find the number of metric tons of corn produced by each country.  

Answers

Answer:

Number of metric tons of corn produced by country A = 373 million MT

Number of metric tons of corn produced by country B = 234 million MT

Number of metric tons of corn produced by country C = 57 million MT

Step-by-step explanation:

From the given information we have

A+B+C = 664 ____equation(1)

A = B+C+82 ____equation(2)

B = C + 177 ____equation(3)

1) Plugging in B=C+177 into equation 2, we get

A = B+C+82

=> A = (C+177) + C +82

=> A = C+177+C+82

=> A = C +C +177+82

=> A= 2C +  259 ____let it be equation (4)

2) Plugging in A=2C+259 from equation 4 and B=C+177 from equation 3 into the equation 1, we get

A+B+C = 664

=> (2C+259)+(C+177)+C = 664

=> 2C+C+C+259+177 = 664

=> 4C + 436 = 664

3) Subtracting 436 from both the sides, we have

4C + 436 - 436 = 664 - 436

4) Cancelling out +436 and -436 from the left side, we get

4C = 228

5) Dividing both the sides by 4, we get

[tex]\frac{4C}{4} = \frac{228}{4}[/tex]

6) Cancelling out the 4's from the left, we get

C = 57

7) Plugging in C=57 into the equation 3, we get

B = C + 177

=> B = 57+177

=> B = 234

8) Plugging in B=234 and C=57 into the equation 1, we get

A+B+C = 664

=> A+234+57=664

=> A + 291= 664

9) Subtracting 291 from both the sides, we get

A + 291 - 291 = 664 - 291

10) Cancelling out +291 and -291 from the left side, we get

A = 373

So, A = 373, B= 234, C=57

What is the equation of a line that is perpendicular to 4x-3y=12 and passes through (-8,1)?

Answers

Answer:

y=-(3/4)x-5

Step-by-step explanation:

First we must write our equation in slope intercept form:

[tex]y=mx+b[/tex]

Where m is slope and b is the y-intercept.

[tex]4x-3y=12\\\\-3y=-4x+12\\\\y=\frac{4}{3}x-4[/tex]

Now we will find a line that is perpendicular to [tex]y=\frac{4}{3}x-4[/tex]

To do this we will get the negative inverse of our original slope which is 4/3 and the negative inverse is: [tex]-\frac{3}{4}[/tex].

Now we must determine our y-intercept for the perpendicular line by using the slope calculated above and plugging it in to the following equation:

[tex]y=m(x-x_1)+y_1[/tex]

Where m is the slope, x1 = -8 and y1=1 and so:

[tex]y=-\frac{3}{4}(x-(-8))+1\\\\y=-\frac{3}{4}x-\frac{24}{4}+1\\\\y=-\frac{3}{4}x-6+1\\\\y=-\frac{3}{4}x-5[/tex]

A set of data follows a nonstandard normal distribution curve. Find the probability that a randomly selected value will be between 660 and 680 given mean of 715 and a standard deviation of 24
Options:
0.9169

0.7100
0.8300

Answers

Answer:

0.0611

Step-by-step explanation:


Answer:

B. 0.0611

Step-by-step explanation:

We have been given that a data set which follows a nonstandard normal distribution curve and mean of data set is 715 and standard deviation is 24.

To find the probability that a randomly selected value will be between 660 and 680 we will use probability formula to find the values between two z-scores.

First of all let us find z-score for our given values using z-score formula.

[tex]z=\frac{x-\mu}{\sigma}[/tex], where,

[tex]z=\text{ z-score}[/tex],

[tex]x=\text{Random sample score}[/tex],

[tex]\mu=\text{ Mean}[/tex],

[tex]\sigma=\text{ Standard deviation}[/tex].

Let us find z-score for random score 660.

[tex]z=\frac{660-715}{24}[/tex]

[tex]z=\frac{-55}{24}[/tex]

[tex]z=-2.29[/tex]

Let us find z-score for random score 680.

[tex]z=\frac{680-715}{24}[/tex]

[tex]z=\frac{-35}{24}[/tex]

[tex]z=-1.458\approx -1.46[/tex]

We will use formula [tex]P(a<z<b)=P(z<b)-P(z<a)[/tex] to find the probability between our given values.

Upon substituting our given values in above formula we will get,

[tex]P(-2.29<z<-1.46)=P(z<-1.45)-P(z<-2.29)[/tex]

Using normal distribution table we will get,

[tex]P(-2.29<z<-1.46)=0.07215-0.01101[/tex]

[tex]P(-2.29<z<-1.46)=0.06114[/tex]

Therefore, the probability that a randomly selected value will be between 660 and 680 is 0.0611 and option B is the correct choice.

Answers

Answer:

The total cost charged by the two companies will be the same for 10 square yards of carpeting .

Step-by-step explanation:

Let us assume that the number of square yards for carpeting  used be x.

Let us assume that the total cost of the  charged by the companies be y.

As given

Country Carpets charges $22 per square yard for carpeting, and an additional installation fee of $100.

Than the equation becomes

y = 22x + 100

As given

City Carpets charges $25 per square yard for the same carpeting, and an additional installation fee of $70.

Than the equation becomes

y = 25x + 70

Than the two equations are

y = 22x + 100 and y = 25x + 70

Than compare the two equations are

22x + 100 = 25x + 70  

25x - 22x = 100 - 70

3x = 30

[tex]x = \frac{30}{3}[/tex]

x = 10 square yards .

Therefore the total cost charged by the two companies will be the same for 10 square yards of carpeting .

a) Choice D -- Graph is discrete due to b only taking on whole number values (b = 0, b = 1, b = 2, etc)

see the attached image below for the graph

---------

b) She bought 9 basketballs

====================================================

Explanation for part A

To make a table, we simply replace every copy of 'b' with a positive whole number. So for instance, replace b with 0 and we get

a = 18*b = 18*0 = 0

Therefore b = 0 leads to a = 0 meaning buying 0 basketballs cost the coach $0

If b = 1, then a = 18 because

a = 18*b = 18*1 = 18

So 1 basketball costs $18 as expected

2 basketballs cost a total of $36 and we see that as shown below

a = 18*b = 18*2 = 36

This pattern continues however long as you need. Each row of the table represents an ordered pair of (b,a) values. Unfortunately your teacher made 'b' the independent variable meaning that it must come first even if the temptation is to put 'a' first in the ordered pair due to alphabetical order.

To graph this function, we just plot the points from the table. Each row is an ordered pair so it represents 1 point. We do NOT connect the dots with a straight line. Why not? Because we can't buy half a basketball, so the point with b = 1/2 = 0.5 wouldn't make any sense, so it's no use to us. The fact we have disconnected points as the graph shows visually tells us that we have a discrete graph. Connecting the dots would make the graph continuous.

Once again, have a look at the image attached below for the table and graph.

-----------------------

Explanation for part B

The equation in part A helps us find the pre-tax total cost. If that cost is $162, then a = 162 and b is...

a = 18*b

162 = 18*b

18*b = 162

18*b/18 = 162/18

b = 9

So she bought 9 basketballs

This is represented as point J(9,162) on the graph below.

x - 1  ----> x + 2  shifts  it 3 units to the left.

3 ---->5  shifts it 2 units up.

Answer:

Options 3 & 4

Step-by-step explanation:

Recall, an exponential function has the basic form  

[tex]y=ab^{x+h}+k[/tex].

a produces a vertical stretch or shrink b is the ratex is the input valueh shifts the function left and right opposite to the sign of itk shifts the function up and down

Thus [tex]f(x)=2^{x-1} +3[/tex] is shifted to the right 1 unit and up 3 units.\\

This means that [tex]g(x)=2^{x+2}+5[/tex] is shifted to the left 2 units and up five units.

Remember it had already been shifted up 3 so, moving up to 5 is a movement of 2 units. Option 3 is correct.

Also, remember the function started 1 unit to the right and then shifted left to 2. This would be 1--2=3 units in total were shift from f(x) to g(x). This makes Option 4 correct too.


In 1992, the population in a town was 8,000 people. In 1997, the population was 14,000. What was the percent increase in the population?

Answers

Answer:

75%

Step-by-step explanation:

To calculate the percent increase or decrease, we:

Find the difference between the new value and the originalDivide the number by the originalMultiply by 100 and the % symbol.

The population of the town originally had 8,000 in 1992. In 1997, the population is 14,000.

14000-8000=60006000/8000=0.750.75(100)=75%

The towns population increase by 75%


To find the percent increase in the population from 1992 to 1997, subtract the initial population from the final population, divide by the initial population, and multiply by 100, resulting in a 75% increase.

To calculate the percent increase in the population of the town from 1992 to 1997, follow these steps:

Subtract the initial population in 1992 from the final population in 1997 to find the absolute increase: 14,000 - 8,000 = 6,000 people.Divide the absolute increase by the initial population to get the increase relative to the initial population: 6,000 \/ 8,000 = 0.75.Multiply the result by 100 to convert it to a percentage: 0.75 * 100 = 75%.

Therefore, the percent increase in the population from 1992 to 1997 was 75%.

A man drove x miles per hour for 3 hours and (2x-60) miles per hour for the next 4.75 hours. A)Express the total distance traveled in terms of x

Answers

Answer:

[tex]12.5x-285[/tex].

Step-by-step explanation:

We are told that a man drove x miles per hour for 3 hours, so he traveled 3x miles in three hours.

We are also told that he drove (2x-60) miles per hour for the next 4.75 hours. So The distance traveled by in next 4.75 hours will be:

[tex]4.75\cdot (2x-60)=9.5x-285[/tex]  

To find the total distance traveled by man we will add distances traveled by him in first 3 hours and next 4.75 hours.

[tex]\text{The total distance traveled}=3x+9.5x-285[/tex]

Upon combining like terms we will get,

[tex]\text{The total distance traveled}=(3+9.5)x-285[/tex]

[tex]\text{The total distance traveled}=12.5x-285[/tex]

Therefore, the total distance traveled in terms of x will be [tex]12.5x-285[/tex].

The total distance traveled in terms of x is the sum of the distances for each part of the trip: 3x miles for the first part and 9.5x - 285 miles for the second part, equating to a total distance of 12.5x - 285 miles.

To express the total distance traveled in terms of x, we need to use the distance formula d = vt, which states that distance (d) is equal to velocity (v) multiplied by time (t).

For the first part of the trip, the man drove at x miles per hour for 3 hours. Therefore, the distance for this part is:

d1 = x miles/hour * 3 hours = 3x miles

For the second part of the trip, he drove at (2x-60) miles per hour for 4.75 hours. So, the distance for this part is:

d2 = (2x-60 miles/hour) * 4.75 hours = 9.5x - 285 miles

To find the total distance traveled, we add the two distances together:

Total Distance = d1 + d2 = 3x miles + 9.5x - 285 miles = 12.5x - 285 miles

Answers

Answer:

Option d is correct.

Both the x and y coordinates of the point on δa'b'c' have opposite signs from the corresponding points on δabc.

Step-by-step explanation:

The rule of 180 degree rotation about the origin is:

[tex](x, y) \rightarrow (-x , -y)[/tex]

Since a Rotation of a point through 180°, about the origin when a point a(h, k)  is rotated about the origin through 180° in anticlockwise or clockwise direction.

then, By the rule of 180 degree rotation;

[tex]a(h, k) \rightarrow a'(-h , -k)[/tex]

so, it takes the new position i.e, [tex]a'(-h , -k)[/tex]

Therefore, both the x and y coordinates of the point on δa'b'c' have opposite signs from the corresponding points on δabc.

between a mixture and substance which can be separated into components & what are the two ways?

Answers

Answer:


Step-by-step explanation:

Introduction:

Mixtures are not unique to chemistry; we encounter them on a daily basis. The food and drinks

we consume, the fuel we use in our vehicles, building materials, soil, air, and ordinary water are

all mixtures. In fact, very few common materials in the world are pure. Any material made up

of two or more substances that are not chemically combined is a mixture. It is not difficult to

separate the components of a mixture if you take advantage of differences in physical properties

of the components.

1. Sublimation. Some substances change directly from a solid to a gas when they

are heated. The reverse process, when the vapor goes back to the solid phase

without a liquid state in between, is called deposition. Some solids which sublime

are iodine, caffeine, and paradichlorobenzene (mothballs). Dry ice sublimes also.

2 Extraction. This uses a solvent to selectively dissolve one component of the

solid mixture. With this technique, a soluble substance can be separated from an

insoluble substance.

3. Decantation. This separates a liquid from insoluble solid sediment by carefully

pouring the liquid from the solid without disturbing the solid.

4. Filtration. This separates a solid from a liquid through the use of a porous

material as a filter. Paper, charcoal, or sand can serve as a filter. These materials

trap the solid but let the liquid pass through (see diagram in Procedure section).

5. Evaporation. This is the process of heating a mixture in order to remove a

liquid that evaporates easily, leaving a dry residue.  

Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.

[tex]1 m = 100 cm[/tex]

[tex]1 inches = 2.54 cm[/tex]

[tex]1 ft = 12 inches[/tex] and

[tex]1 yard = 3 ft[/tex]

1 ft = 12 inches

3 ft = [tex]3 \times 12 = 36 inches[/tex]

Since,

1 inches  = 2.54 cm

36 inches = 91.44 cm

Also,

1 m = 100 cm

1 m = 100 cm

or

1 cm =

then;

91.44 cm =

⇒ 1 yards = 0.9144 m

Divide both sides by 0.9144 we get;

1 meter =  yards.

Therefore, the answer is, 1 m =  1.1 yards (nearest to tenth)

The distance between the cities Chicago and Toronto is 540 miles. A motorcycle's speed is 48 mph. For a car, it takes 2.25 hours less to cover the same distance than for the motorcycle. How long does it take them to meet, if they start moving towards each other simultaneously?

HELP PLEASE

Answers

Answer:

Motorcycle will complete the 540 mile trip in 11.25 hr.

The car will complete it 2.25 hours less, or 9 hours.

The speed of the car therefore is 540/9 = 60 mph.

60t + 48t = 540

108t = 540

t = 5

So they will meet in 5 hours, after which time the motorcycle will have traveled 48*5 = 240 miles

and the car will have traveled 60*5 = 300 miles.

Hope this help

Mrs. Hool is planning on grading tests over the weekend. The number of tests that she has left to grade after each hour can be modeled by the equation = 78 − 15ℎ, where is the number of tests left to grade and ℎ is the number of hours she has worked on grading. What is the meaning of the values 78 and −15 in this equation?

Answers

Answer:

-15 is how many tests per hour i think, and 78 is how many tests total

Step-by-step explanation:

= 78 − 15ℎ

1 hour would be

78-(15x1)=63

2 hours would be

78-(15x2)=48

and so on.

Final answer:

The value 78 represents the initial number of tests Mrs. Hool has, while -15 represents the rate at which she grades tests per hour.

Explanation:

The values 78 and -15 in the equation represent the initial number of tests that Mrs. Hool has and the rate at which she grades the tests per hour, respectively.

The value 78 is the initial number of tests that Mrs. Hool has left to grade. This means that when she starts grading, she has 78 tests remaining.

The value -15 represents the rate at which Mrs. Hool grades the tests per hour. It indicates that for every hour she works on grading, she is able to complete 15 fewer tests than what she started with. In other words, the number of tests she has left decreases by 15 for every hour she works.

Sulfuric acid is essential to dozens of important industries from steelmaking to plastics and pharmaceuticals. More sulfuric acid is made than any other industrial chemical, and world production exceeds 2.0 x 10 kg per year. The first step in the synthesis of sulfuric acid is usually burning solid sulfur to make sulfur dioxide gas. Suppose an engineer studying this reaction introduces 4.4 kg of solid sulfur and 6.90 atm of oxygen gas at 950. C into an evacuated 50.0 L tank. The engineer believes K-0.71 for the reaction at this temperature. Calculate the mass of solid sulfur he expects to be consumed when the reaction reaches equilibrium. Round your answer to 2 significant digits. Note for advanced students: the engineer may be mistaken in his belief about the value of Kp, and the consumption of sulfur you calculate may not be what he actually observes.
