The perimeter of a rectangle is 64 inches. Find the value of x if the width is 22 inches and tenth is 2x inches.
Dmitry [639]

Answer:

5

Step-by-step explanation:

Did you mean length instead of tenth? If so, 22*2=44, 64-44=20, 20/2=10. The length of the rectangle is 10 so to find the value of x, divide 10 by 2 so, 10/2=5, and x is equal to 5. : )

What is the volume enclosed by the slanted prism in the diagram? A. 225 cm3 B. 270 cm3 C. 300 cm3 D. 540 cm3
Leokris [45]

Answer:

<h2>A. 225 cm3</h2>

Step-by-step explanation:

The volume of a slanted prism is defined as the product between the area of its base and its height.

Remember that height is the distance from the top to the bottom, reaching that bottom with a perpendicular angle.

So, in this case, the height is 9 cm, and the area of the base is 25 square centimeter.

This means the volume is

V=Bh=25cm^{2}(9cm)=225cm^{3}

Therefore, the right answer is A.
