The flag pole is 20 feet tall with an 8 foot shadow.

The tree is X feet tall with a 12 foot shadow.

20/8 = X/12

Cross multiply:

20 * 12 / 8*X

240 = 8x

Divide both sides by 8:

x = 240/8

x = 30

The tree is 30 feet tall.

An arc subtends a central angle measuring 7pi/4 radians

Mumz [18]

Answer:

$\frac{7}{8}$

Step-by-step explanation:

In any circle the following ratios are equal

$\frac{centralangle}{2\pi }$ = $\frac{arc}{circumference}$

$\frac{\frac{7\pi }{4} }{2\pi }$ = $\frac{7}{8}$ = $\frac{arc}{circumference}$

Please solve this geometry equation with the work ! for 40 points and brainliest

topjm [15]

Answer:

D. 16 times.

Step-by-step explanation:

Volume of a cylinder = π r^2 h

π r^2 h = 432

Now if the diameter is reduced by 1/4 then the radius is reduced by a fourth also.

Let the new height be H, then:

432 = π (r/4)^2 H

so π r^2 h = π(r/4)^2 H

r^2 h = r^2 H / 16

h = H/16

H = 16h.

valina [46]

Answer:

<em>I will need to buy 22.5 pounds of turkey and pay $23.63</em>

Step-by-step explanation:

<u>Proportions</u>

Each person is planned to eat 2 x 3/8 pound servings of turkey for thanksgiving dinner. This means each person will eat

$2\cdot\frac{3}{4}=\frac{3}{2}$

pounds of turkey.

There are going to be 15 people at the dinner, thus the total turkey needed is:

$15\cdot\frac{3}{2}=22.5~pounds$

The turkey costs $1.05 per pound, thus the total cost is

22.5*$1.05 = $23.63

I will need to buy 22.5 pounds of turkey and pay $23.63
