Answer:

1. C

2. C

3. 48 in

4. C

Step-by-step explanation:

1. A perfect square is a number that can be expressed as n * n, where n is an integer. A perfect cube is a number that can be expressed as n * n * n, where n is an integer again. The three given numbers suffice both properties, hence the answer is C.

2. The volume is 9 * 9 * 9 = 729 cubic inches. We want to fit 1000 cubic inches in the box, so not everything wil fit as 729 < 1000.

3. The side lengths of the square, s, may be solved by s^2 = 144, which gives s = 12. So the perimeter is 4s = 48.

4. The area of the square is 64 square inches, so each of the side lengths measures sqrt(64) = 8 inches.

The perimeter of a rectangle is 20 inches.The length is 2 inches less than twice the width.
SSSSS [86.1K]

Answer:

width = 6

length = 4

Step-by-step explanation:

perimeter = 2L + 2W

L = W - 2

plug in perimeter:

20 = 2L + 2W

you know the length is 2 less than the width

plug in (w - 2) for L:

20 = 2(w - 2) + 2w

solve for w:

20 = 2w - 4 + 2w

20 = 4w - 4

4w = 24

w = 6

now plug in 6 for w in either equation, whichever is easier to solve:

L = 6 - 2

L = 4

width = 6

length = 4

J.K. Rowling and R.L. Stine are both reading the hunger games. J.K. reads 35 pages every 2 hours and R.L. reads 45 pages every 3
Lilit [14]

Attention:THIS IS PART B <em>ONLY!</em>

First,find the unit rate.

35/2   and   <em>x</em>/1

35 divided by 2 = 17.5 so the unit rate for J.K. is 17.5 pages per hour.

now,R.L.

45/3   and  <em>x</em>/1

45 divided by 3 = 15 so the unit rate for R.L. is 15 pages per hour

now we need to divide 355 by 17.5 and divide it by 15.Whichever quotient is smaller,finishes the book first

355 divided by 17.5 = about 20 hrs----J.K.

355 divided by 15 = about 24 hrs-----R.L.

So,who read faster?
