Julie has a jewlery box shaped like a cube. The volume of the jewlery box is v cubic inches. Write an
Stolb23 [73]

Answer: ∛v

Step-by-step explanation:

Since we know volume is measured height x width x length, we know the equation we'd use here would be:

___ x ___ x ___ =  v in³

If this was area, we would have ___ x ___ = v in², and it would be easy to find each blank. You would just find the square root of "v", making your answer √v.

When you have 3 things multiplied by each other (that are exactly the same, which is the situation here since this is a cube), you will want to find ∛x (if x is our unknown variable). This means that we are finding ONE-THIRD of the number ... sort of. So if x was equal to 8, then ∛x = 2, because 2 x 2 x 2 = 8.

In our situation here, x = v, and since we don't know the actual number, we will keep it as a square root, so the answer to your question is ∛v.

I really hope I was able to explain easy enough, feel free to ask anything else!

What could be the intersection of plane PRS and plane QRS?
Mariana [72]

Answer:

The plane PRS passes through the points P, R and S. So it contains the line RS. Also the plane QRS passes through the points Q, R and S. So it contains the line RS as well. Since both the planes contain the line RS, the line RS must be the intersection of plane PRS and QRS

I have no idea how to solve this
LiRa [457]

Answer:

X = 8

Step-by-step explanation:

Since the shape is a parallelogram the opposite sides are equal

The equation is:

  • 6 = 2x -10

Solve:

  • 6 + 10 = 2x -10 + 10
  • 16 = 2x
  • 2x = 16
  • Divide by 2 on both sides
  • <u>x = 8</u>

Check:

  • 2(8) - 10 = 6
  • 16 - 10 = 6
  • 6 = 6
  • CD = BE
  • 6 = 6
