~S O M E O N E ~ H E L P ~ M E~ Sarah has a wall hanging in the shape of a parallelogram. What is the height of the wall hanging if its area and base are 300 square centimeters and 20 centimeters respectively?

Option D

Step-by-step explanation:

Height = Area/ base

Height = 300 cm² / 20 cm

Height = 15 cm

The area of a parallelogram is base times height because it can be rearranged into a rectangle with the same area.

We can also check our answer by plug the value in the formula A = b x h

A = 20 cm x 15 cm

A = 300 cm²

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
