The volume of a cube is 8000 cubic feet, what is the area of one of its faces?
eimsori [14]

Since a cube is l x w x h, find the length of one side first:

∛8,000 = 20

The length of one side is 20 feet. This can represented as "s".

To find the area of one of the faces, use s²:

20²   or   20 x 20 = 400

The area of one face is 400 ft²!

Jake and Gloria are running on the track team. Gloria can run twice as many miles as
Tanzania [10]

Answer:

J+2J=12 so 3J=12 so J=4

Step-by-step explanation:

Use J to represent Jake's miles.

We know that Gloria's miles (G) is twice J, so G=2J

We also know that Jake and Gloria together ran 12 miles.

So we know, J+2J=12 or 3J=12   meaning J=4

So Jake runs 4 miles, and since Gloria is two times that she ran 8 miles.

How do I solve x+4y=22<br> -x+5y=23
xxTIMURxx [149]
{ x + 4y = 22     ( + x - x = 0 )
{ - x + 5y = 23

4y + 5y = 22 + 23
9y = 45
  y =<u> 45 </u>
         9
  y = 5

x + 4y = 22
x + 4 . 5 = 22
x + 20 = 22
x = 22 - 20
x = 2

S = { 2 , 5 }
