➷ The formula for circumference is \pi d

1) \pi d = 31.4

Divide both sides by \pi

d = 9.99 (consider this to be 10)

Half this to find the radius

10/2 = 5

It would be figure B.

2) \pi d = 37.68

Divide both sides by \pi:

d = 11.99 (consider this to be 12)

Divide by 2 to find the radius:

12/2 = 6

It would be figure C.

3) area = \pi r^2

\pi r^2 = 153.86

r^2 = 48.97515909

r = 6.998 (consider this to be 7)

It would be figure D

4) \pi r^2 = 113.04

r^2 = 35.98174

r = 5.998 (consider this to be 6)

It would be figure C.

5) radius = diameter / 2

radius = 3

\pi (3)^2 = 28.27433

It would be option C

The regression equation y = -0.414x + 106.55 approximates the percent of people in an
murzikaleks [220]

The correct option will be:   A. 67%

<em><u>Explanation</u></em>

Given equation is:   y = -0.414x + 106.55 , where x is the length of the film in minutes and y is the percentage of people finish watching the film.

Here, the length of the documentary is given as 95 minutes. So, we will <u>plug x=95 into the above equation</u> and get....

y=-0.414(95)+106.55\\ \\ y=-39.33+106.55\\ \\ y=67.22 \approx 67

<em>(Rounded to the nearest percent)</em>

So, the percentage of people in an audience who will finish watching a documentary that is 95 minutes long will be 67%

If b is the midpoint of ac, ab=12x+11 and bc= 14x - 1, find AB
xxMikexx [17]

Answer:

AB = 83

Step-by-step explanation:

The mid-point of any segment divides the segment into two equal parts

∵ B is the midpoint of segment AC

→ That means B divides AC into two equal segments AB and BC

∴ AB = BC

∵ AB = 12x + 11

∵ BC = 14x - 1

→ Equate them

∴ 14x - 1 = 12x + 11

→ Subtract 12x from both sides

∵ 14x - 12x - 1 = 12x - 12x + 11

∴ 2x - 1 = 11

→ Add 1 to both sides

∵ 2x - 1 + 1 = 11 + 1

∴ 2x = 12

→ Divide both sides by 2

∵ \frac{2x}{2}=\frac{12}{2}

∴ x = 6

→ To find AB substitute x by 6 in its expression

∵ ab = 12x + 11

∵ x = 6

∴ AB = 12(6) + 11

∴ AB = 72 + 11

∴ AB = 83

Can anyone help please?
Furkat [3]
Alternate interior angles are equal.
2x - 10 = 65 - x
2x + x = 65 + 10
3x = 75
x = 75/3 = 25
x = 25.
