Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4. Find the difference between 16 and 10. Add the difference to 16. Find the difference between 16 and 10. Add the difference to 7.5.

Answers

Answer:

Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4.

Step-by-step explanation:

Given

Minutes: 10 || 16 || ?  || 48

-----Miles: 2.5 || 4 || 7.5 || 12

Required

Which statements solve for the missing value?

First, we need to calculate the ratio of minutes to mile

[tex]Ratio = \frac{Minutes}{Mile}[/tex]

When minutes = 16; mile = 4

So, we have:

[tex]Ratio = \frac{16}{4}[/tex]

[tex]Ratio = 4[/tex]

Next, we multiply the ratio by 7.5

[tex]Minutes = Ratio * 7.5[/tex]

[tex]Minutes =4 * 7.5[/tex]

[tex]Minutes = 30[/tex]

Hence, option B answers the question.

Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation.

If y varies as directly as the square of x, and y = 75/8 when x = 5, find y when x= 2​

Answers

Answer:y=15/4

Step-by-step explanation:

start with general form y = kx. substitute in the pair of values you know for x and y.

75/8 = k(5) multiply both sides by 1/5 to solve for k, getting

15/8 = k

So your equation is y = (15/8)x substitute 2 for x to find your new y.

y = (15/8)2

y = 15/4

Answers

Answer:

Step-by-step explanation:

tan e = x/(4x-1)

tan f = (6x+5)/(12x + 31)

since tan e = tan f

x/(4x-1) = (6x+5)/(12x+31)

x(12x+31) = (4x-1)(6x+5)

12x^2 +31x = 24x^2 +20x -6x -5

31x = 12x^2 +14x -5

0 = 12x^2 -17x -5

0 = (12x -5)(x -1)

x = 1, 5/12

Suppose A and B are points on the number line. If AB = 8 and B lies at −7, where could A be located?
Select ALL that apply.
−1
1
15
−15

Answers

Answer:

The correct answers are: 1 and -15

Step-by-step explanation:

Let a be a point on number line and b be the second point on number line.

The distance between two numbers on number line is calculate by subtracting the smaller number from larger number.

Here

AB = 8

B = -7

We have to look at the options one by one.

For A = -1

As A>B

[tex]AB = B-A = -1-(-7) = -1+7 = 6[/tex]

For A = 1

As A>B so

[tex]AB = A-B = 1-(-7) = 1+7 = 8[/tex]

So with A = 1 , AB = 8

This is one of the right answers.

For A=15

As A>B

[tex]AB = A-B = 15-(-7) = 15+7 = 22\\[/tex]

For A=-15

As B>A

[tex]AB = B-A = -7-(-15) = -7+15 = 8[/tex]

As with A=1 and A=-15, the distance between AB is 8 so these are the correct answers.

Hence,

The correct answers are: 1 and -15

Radius = 23/2 in

Time = 1 min

Find:

Speed

Computation:

Total distance = 2πr(1000)
