The length of a rectangle is 8 feet longer than the width. if the perimeter is 108 feet, find the length and width of a rectangle.

perimeter = 2L +2W

L=w+8

perimeter = 2(w+8) +2w

108 =2w +16 +2w

108=4w+16

92=4w

w=92/4 = 23

l=23+8 = 31

23*2 =46, 31*2 = 62, 62 +46 = 108

length = 31 feet

width = 23 feet

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

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
