Answer:

Jonelle's

Step-by-step explanation:

Cube is made up of square faces. The sides of a square equal.

The general formula of volume= Area of base X the height of the object

The area of the base of a cube (square) is calculated with the formula: Length X Length = L to the power of 2.

The area of the base must be multiplied by the height of the object to get the volume.

*You already know that all the dimensions on a cube are equal.

Therefore, the height of the cube will be equal to the Length of the square.

Length to the power of two(this is the area of the base) X Length (the length is equal to the height because the object is a cube)

=Length to the power of three.

The sum of the first and third consecutive add integers is 131 less than 3 times the second integer.Find the 3 integers.Pls writ

Arisa [49]

3 consecutive odd integers....x, x + 2, and x + 4

x + x + 4 = 3(x + 2) - 131
2x + 4 = 3x + 6 - 131
2x + 4 = 3x - 125
2x - 3x = - 125 - 4
-x = - 129
x = 129

x + 2 = 129 + 2 = 131
x + 4 = 129 + 4 = 133

so ur 3 odd numbers are : 129,131, and 133 <==

Homework (5)

Answer:

Step-by-step explanation:

Let's set the ratio as

7x : 9x

If you add all the states that border an ocean and do not, you will get 48 states (because Alaska and Hawaii are not part of the continental US, as they do not touch the "main" part of the country)

So, we can write this equation.

7x + 9x = 48

Simplify.

16x = 48

Divide both sides by 16.

x = 4

Now, find how many states border an ocean. In our ratio, the number of states that border an ocean was 7x. Substitute x = 4 into 7x

7 * x = 7 * 4 = 28

The number of states that border an ocean is 28.

I hope this helps! Feel free to ask any questions!
