n trapezoid STUV, SW is an altitude. Which is equivalent to the measure of angle m + n + p if m angle VSW = 65 degrees?

Answers

Answer:

The measure of angle m+n+p is equivalent to 205° (Fourth option)

Step-by-step explanation:

In a quadrilateral, the sum of the interior angles must be equal to 360°:

S=m+n+p+m<VSW+m<WST=360°

m<VSW=65°

Like SW is an altitude, m<WST=90°

Replacing the known values in the formula above:

m+n+p+65°+90°=360°

Adding like terms:

m+n+p+155°=360°

We want m+n+p, then subtracting 155° both sides of the equation:

m+n+p+155°-155°=360°-155°

m+n+p=205°

Answer:

4th Option is correct.

Step-by-step explanation:

Given: STUV ia a trapezoid that is ST is parallel to UV

          SW is altitude that is m∠ SWV = 90°

          m∠ VSW = 65°

To find: measure of m + n + p

Since, ST is parallel to UV.

⇒ n + p = 180° because Sum of Interior Angle on the same side of traversal is 180°

Now, In ΔSVW

∠SVW + ∠SWV + ∠WSV = 180° (Angle sum property of triangle)

m + 90° + 65° = 180°

m + 155 = 180

m = 180 - 155

m = 25°

Thus,  m + n + p = 25 + 180 = 205°

Therefore, 4th Option is correct.

Suppose your car gets 28 miles per gallon of gasoline, and you are driving at 55 miles per hour. Using unit analysis, find the amount of gas you use every hour.

Answers

Answer:

1 27/28 ≈ 1.964 gallons/hour

Step-by-step explanation:

You want gallons in the numerator of your unit rate, but that unit is in the denominator of the mileage rate. So, the computation must involve division by 28 mpg. Hours is already in the denominator of 55 mph, so the computation will involve multiplication by that rate.

... (55 mi/h)/(28 mi/gal) = (55 mi/h)·(1 gal/(28 mi)) = 55/28 gal/h

... = 1 27/28 gal/h

Final answer:

To calculate the gas usage per hour, divide the speed of 55 mph by the car's fuel efficiency of 28 mpg, resulting in approximately 1.9643 gallons of gas used per hour.

Explanation:

To determine the amount of gas used every hour by a car that gets 28 miles per gallon (mpg) and is travelling at 55 miles per hour (mph), we can use unit analysis as follows:

Understand the given information: The car's fuel efficiency is 28 mpg, and its speed is 55 mph.Set up the units so that miles cancel out, and you are left with gallons per hour. This can be done by dividing the speed of the car (in miles per hour) by the fuel efficiency (in miles per gallon).Compute the amount of gas used per hour: 55 mph / 28 mpg = 1.9643 gallons per hour (rounded to four decimal places).

Therefore, the car uses about 1.9643 gallons of gasoline per hour when driving at a constant speed of 55 mph.

Problem 3 among the cast aluminum parts manufactured on a certain day, 80% were flawless, 15% had only minor flaws, and 5% had major flaws. find the probability that a randomly chosen part

a.has a flaw (major and minor).

b.has no major flaws.

Answers

Greetings!

Answer:

A) P(flaw) = 0.2

B) P(No major flaws) = 0.95

Step-by-step explanation:

A)

To find the probability of flaws, we can find the probability of no flaws first by dividing by 100:

P(no flaw) = [tex]\frac{80}{100}[/tex] = 0.8

So then:

P(flaw) = 1 - P(no flaw) = 1 - 0.8 = 0.2

P(flaw) = 0.2

B)

First, we need to find the probability of major flaws:

P(major flaws) = [tex]\frac{5}{100} = 0.05[/tex]

P(Major flaws) = 0.05

So to find the probability of no major flaws:

P(No major flaws) = 1 - P(major flaws) = 1 - 0.05 = 0.95

P(No major flaws) = 0.95


Hope this helps!
Final answer:

According to known percentages, it can be concluded that the probability a part has a flaw is 20% (0.20), and the probability a part has no major flaws is 95% (0.95).

Explanation:

This question is about probability in Mathematics. Specifically, it's based on the principles of probability distribution. Given that we know the percentages for flawless, minorly flawed, and majorly flawed parts, we can calculate the requested probabilities as follows:

The probability that a part has a flaw (major or minor) is the sum of the probabilities of a part having minor flaws and major flaws, so 15% + 5% = 20%, or 0.20 when expressed as a decimal.The probability of a part having no major flaws includes both flawless parts and parts with minor flaws. Therefore, its probability equals 80% + 15% = 95%, or 0.95 in decimal form.

Ella collects 50 bottles to recycle. Of the bottles she collects, 19 are plastic and the rest are glass.

A.) What percent of the bottles are plastic?

B.) What percent of the bottles are glass?

*Please Show Work*

Answers

QUESTION A

The total number of bottles Ella collected is
[tex]50[/tex]


The number of bottles that are plastic is

[tex]19[/tex]

The percentage of bottles that are plastic is

[tex] = \frac{number \: of \: plastic \: bottles}{total \: number \: of \: bottes} \times 100\%[/tex]

[tex] = \frac{19}{50} \times 100\%[/tex]

[tex] = 19 \times 2\%[/tex]
[tex] = 38\%[/tex]

Therefore 38% of the bottles are plastic.



QUESTION B

The total number of bottles that are glass is
[tex]50 - 19 = 31[/tex]

The total number of bottles Ella collected is
[tex]50[/tex]

The percentage of bottles that is glass is
[tex] = \frac{number \: of \: glass \: bottles}{total \: number \: of \: bottles} \times 100\%[/tex]

[tex] = \frac{31}{50} \times 100\%[/tex]

[tex] = 31 \times 2\%[/tex]
[tex] = 62\%[/tex]

Therefore 62% of the bottles are glass
Final answer:

38% of the bottles Ella collects are plastic and the remaining 62% are glass. Percentage is calculated by dividing the part by the whole and then multiplying by 100.

Explanation:

Ella has 50 bottles in total, out of which 19 are plastic. To find out what percentage of bottles are plastic, we use the formula:

Percentage = (Part/Whole) * 100

Substitute the given values into the formula we get:

Percentage of plastic bottles = (19/50) * 100 = 38%

For the percentage of glass bottles, we first need to find out how many bottles are glass. As the total number of bottles are 50 and 19 of these are plastic, we subtract 19 from 50 to find the number of glass bottles:

Total glass bottles = 50 - 19 = 31

Now we can find out what percentage of bottles are glass using our formula:

Percentage of glass bottles = (31/50) * 100 = 62%

So, 38% of the bottles Ella collects are plastic and 62% are glass.

(Round your answer to the nearest tenth.)

Answers

Answer:

Length of the segment QS = 11.76 cm

Step-by-step explanation:

We are given with right angle triangle QRS

Angle S is 80 degree and RS = 2 cm

We need to find out QS

RS is adjacent to angle S, so we use cos formula

[tex]Cos (A) = \frac{adjacent}{hypotenuse}[/tex]

[tex]Cos (S) = \frac{RS}{QS}[/tex]

Plug in the angle and RS

[tex]Cos (80) = \frac{2}{QS}[/tex]

Given cos(80) = 0.17

[tex]0.17= \frac{2}{QS}[/tex]

Multiply by QS on both sides

0.17 * QS = 2

Divide by 0.17 on both sides

If the population will double every 54 years and the population in 1974 was 56000 people, then the function that represents this situation is

[tex]y=56000\cdot 2^{\frac{x}{54}},[/tex]

The sum of two numbers is 52 . The smaller number is 16 less than the larger number. What are the numbers?

Answers

Let the Smaller Number be : S

Let the Larger Number be : L

Given : The Sum of Two Numbers is 52

⇒ S + L = 52 --------------- [1]

Given : The Smaller Number is 16 Less than Larger Number.

It Means if we Add 16 to the Smaller Number, It should be Equal to the Larger Number

⇒ S + 16 = L

⇒ S = L - 16 ------------------ [2]

Substituting Equation [2] in Equation [1], We get :

⇒ L - 16 + L = 52

⇒ 2L = 52 + 16

⇒ 2L = 68

⇒ L = 34

Substituting L = 34 in Equation [2], We get :

⇒ S = 34 - 16

⇒ S = 18

⇒ The Larger Number is 34

⇒ The Smaller Number is 18

Final answer:

The two numbers are 34 and 18; 34 being the larger number and 18 being the smaller number.

Explanation:

This is a common type of problem in algebra called a system of linear equations. We can solve it step by step.

First, let's assign variables to the unknowns. Let's let 'x' be the larger number and 'y' be the smaller number. The problem gives us two equations: x + y = 52 and y = x - 16. Next, we can substitute the second equation into the first one. This gives us: x + (x - 16) = 52.Combine like terms to simplify the equation: 2x - 16 = 52.Add 16 to both sides to isolate '2x': 2x = 68.Finally, divide both sides by 2 to find the value of 'x': x = 34. By substituting 'x' into the second equation, we can also find 'y': y = 34 - 16 = 18.

So, the larger number is 34 and the smaller number is 18.

To find the equation of BC, we must find the slope and use the point B(4,4) with the slope to find the equation.

We know the slope of BC is perpendicular to the slope of AB.

But the slope of AB
[tex] = \frac{4 - 5}{4 - 2} [/tex]

[tex] = - \frac{1}{2} [/tex]

The slope of BC is the negative reciprocal of the slope of AB, which is

In a right triangle with given side lengths and angles, sin α can be calculated using the opposite side and the hypotenuse. The sine function in trigonometry is essential for understanding relationships between angles and sides in triangles. The value of sin α = 3/5.

Explanation:

In this case, we have a right triangle ABC with AB = 9, BC = 12, ∠B = 90°, and ∠A = α.

To find sin α, we use the definition of sine in a right triangle: sin α = opposite/hypotenuse.

Therefore, sin α = opposite/hypotenuse = AB/AC = 9/15 = 3/5.

Answers

Answer:

13 weeks

Step-by-step explanation:

65=5w

w=65/5

w=13

Final answer:

It will take Mark 13 weeks to save $65 for the skateboard by saving $5 each week.

Explanation:

Mark wants to buy a skateboard that costs $65. He plans to save $5 per week. To calculate how many weeks it will take him to save $65, we divide the total cost of the skateboard by the amount Mark can save per week.

Here's the calculation:

Total cost of the skateboard: $65

Amount Mark saves each week: $5Number of weeks needed to save $65: $65 ÷ $5 = 13 weeks

Therefore, it will take Mark 13 weeks to save enough money to buy the skateboard.

Please answer ASAP!! which of the following is closest to 0.25 and why?
A) 9/40 B)5/16 C) 9/32 D) 0.28 E) 15/64

Answers

Answer:

E) 15/64

Step-by-step explanation:

To compare the numbers, it works best to express them all using a common denominator. One possibility is 1600, another is 1,000,000.

9/40 = 360/1600

5/16 = 500/1600

9/32 = 450/1600

0.28 = 448/1600

15/64 = 375/1600

The number we're comparing to is 0.25 = 400/1600, so we want to find the closest number to 400 in the set ...

... {360, 500, 450, 448, 375}.

The magnitude of the differences of these numbers from 400 is ...

... {40, 100, 50, 48, 25}.

Clearly, the last number, 15/64 = 375/1600 has the smallest difference from 0.25.

Answers

Answer:

23.  $ 62.76  to the nearest cent

      $63.00 to the nearest dollar

24.  $ 38.42  to the nearest cent

      $38.00 to the nearest dollar

Step-by-step explanation:

When we round to the nearest cent we round the second number after the decimal.  We look at the third number after the decimal.  If it is 5 or above we round up.

When we round to the nearest dollar, we round the number befroe the decimal. We look at the number after the decimal.  If it is 5 or above we round up.

23.  $62.756  we round the 5 so we look at the 6   6>= 5  so we round up

         $ 62.76  to the nearest cent

    $62.756  we round the 2 so we look at the 7  7>= 5  so we round up

          $63.00 to the nearest dollar

24. $38.415 we round the 1 so we look at the 5   5>= 5  so we round up

         $ 38.42  to the nearest cent

    $38.415  we round the 8 so we look at the 4  4< 5  so we leave alone
