Answer:

5.07

Step-by-step explanation:

The volume of a cube is it's side length squared.

We can represent the side length as x.

x^3=130.

Then, taking the cubic root,

x=5.07

19. Identify the coefficient of 2.<br> O A.X<br> OB.3<br> O c. 2<br> OD. 1

castortr0y [4]

<h3>Answer: C) 2</h3>

The term 2 is really the same as 2*1 = 2x^0. Recall that anything (except 0) to the zeroth power is 1. So the rule is x^0 = 1 when x is nonzero.

Looking at 2x^0, we see that 2 is the coefficient here because it is the constant being multiplied with the variable term.

I don’t understand 7B please help...

joja [24]

Answer:

see explanation

Step-by-step explanation:

let w represent the width then length = w + 7

The perimeter of the rectangle = 2w + 2(w + 7) = 2w + 2w + 14 = 4w + 14

The perimeter is given as 54 m, thus

4w + 14 = 54 ( subtract 14 from both sides )

4w = 40 ( divide both sides by 4 )

w = 10

Thus

width of playground = w = 10 m

length of playground = w + 7 = 10 + 7 = 17 m

The combined area of two squares is 80 square centimeters. Each side of one square is twice as long as a side of the other squar

olganol [36]

Answer:

The length of each side of the larger square is<u> 8 </u>centimeter.

Step-by-step explanation:

Given:

The combined area of two squares is 80 square centimeters. Each side of one square is twice as long as a side of the other square.

Now, to find the length of each side of the larger square.

Let $s$ be the length of the smaller square.

So, the length of the larger square = $2s.$

Now, we find the areas of the square by putting formula:

The area of smaller square = length² $=s^2.$

The area of larger square = (length)² $=(2s)^2=4s^2.$

As, given:

The combined area of two squares is 80 square centimeters.

According to question:

$s^2+4s^2=80\\5s^2=80$

<em>So, dividing both sides by 5 we get:</em>

$s^2=16$

<em>Using square root on both sides we get:</em>

$s=4\ centimeter.$

And, to get the length of each side of the larger square we substitute the value of $s$ :

$2s=2\times 4=8\ centimeter.$

<u>The length of larger square = 8 centimeter</u>

Therefore, the length of each side of the larger square is 8 centimeter.
