Answer:

your answer is D.

Step-by-step explanation:

if you times each number (9, 10, 17, 13) by 14.3 you would find your number like so:

A. 14.3 · 9 = 128.7

B. 14.3 · 10 = 143

C. 14.3 · 17 = 243

D. 14.3 · 13 = 185.9

which gives you your answer and shows explanation of how you got your answer.

Answer:

D 13

Step-by-step explanation:

To find out how many floors the building has, we take the height of the building and divide by the size of each floor

floors = 185.9 ft / 14.3ft per floor

           = 13 floors

In circle V, r = 14ft.
Bad White [126]

For this case we have that by definition, the area of a circle is given by:

A = \pi * r ^ 2

Where:

r: It is the radius of the circle

According to the data of the statement we have that the circle has a radius of 14 \ ft

Substituting in the formula we have:

A = \pi * (14) ^ 2\\A = \pi * 196\\A = 196 \pi

So, the area of the circle is 196 \pi feet squared

Answer:

Option D

How do I find the measure of these two supplementary angles using algebra?
nikdorinn [45]

Answer:

70 and 110

Step-by-step explanation:

The two angles add to 180 degrees since they form a straight line

2x+10 +3x+20 =180

5x+30 = 180

Subtract 30 from each side

5x+30-30 =180-30

5x = 150

Divide by 5

5x/5 =180/5

x = 30

The left angle is 2x+10 = 2*30+10 = 60+10 =70

The right angle is 3x+20 = 3*30 +20 = 90+20 = 110
