What is the area of the figure? Round to the nearest tenth.

nikdorinn [45]

Answer:

letter A

Step-by-step explanation:

This is made up of 4 triangular segments. If we assume the cross section is perpendicular then we can use the 1/2b*h formula for each piece with the given values. So we have 2 triangles with the formula: 1/2(3)*(4.5)=6.75 * 2 triangles = 13.5.

Then for the bottom 2 you have 1/2(3)*7.5=11.25, times 2 triangles =22.5

So, 13.5+22.5=36, or letter A

Step-by-step explanation:

Overhead Cost=$700000

Overhead rate for the current year=Budgeted overhead cost for the current year/Machne hours budgeted

$Overhead rate for the current year=\frac{700000}{100000}$

Overhead Rate for current year=$7

If A=4B and A+B=180 what are A and B

son4ous [18]

Just substitute A = 4B into A + B = 180. So:

4B + B = 180

5B = 180

B = 36

Substitute B = 36 into A = 4B. So:

A = 4*36 = 144
