A company makes concrete paving stones in different sizes. Each stone has a volume of 30 cubic inches and a height of 3 inches.

Zepler [3.9K]

Answer:

There are 5 different sized paving stones that can have a volume of 360 in³.

Step-by-step explanation:

Volume = Area x height.

We are given;

volume; V = 360 in³

Height; h = 3 in

Thus, 360 = A x 3

A = 360/3 = 120 in²

This is the area of the base, so we need to find the number of different stones which have a base area of 120 in².

Let's list all the factors of 120 which are;

1,2,3,4,5,6,10,12,20,24,30,40,60,120

The question says we shouldn't use 1 or 2 in inches as length and width.

Leaving us with the remaining listed factors.

So the pair of factors that give and area of 120 are;

Size;

3 x 40

4 x 30

5 x 24

6 x 20

10 x 12

Thus, there are 5 different sized paving stones that can have a volume of 360.

A banner has a length of 10 feet and an area of 7 square feet. What is the width of the banner?

const2013 [10]

Answer:

the width is 0.7 feet

Step-by-step explanation:

Well we know that area = length * width. We know both the area and length, but not the width. Let's substitute the area and length in this equation, and substitute x for the width.

7 = 10 * x, or 7 = 10x

Now, solve for the width, or x, by dividing both sides by 10.

7(/10) = 10x(/10)

7/10 = x

Simplify 7/10 = 0.7

So the width of the banner is is 0.7 ft!

find the smaller of 2 consecutive integers, x, if the sum of the smaller is 3 times the larger is -5. Write an equation and solv

Leno4ka [110]

You have defined x to be the smaller of two consecutive integers. Then the larger will be (x+1). The given relation is

... (x) + 3(x+1) = -5 . . . . the smaller plus 3 times the larger is -5

... 4x + 3 = -5 . . . . . . . .simplify

... 4x = -8 . . . . . . . . . . subtract 3

... x = -2 . . . . . . . . . . . divide by the coefficient of x

The smaller of the two integers is -2.
