The perimeter of a rectangular rug is 40 ft. It's length is 12 ft. What is it's width?

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

perimeter = 40 ft

length = 12 ft

Substitute the values into the above formula and solve for the width

That's

40 = 2(12) + 2w

40 = 24 + 2w

2w = 40 - 24

2w = 16

Divide both sides by 2

We have the final answer as

Hope this helps you

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

the first one, all those points on the line just make a strait line.
