Kevin works as a part-time vendor selling wallets for $20 each and hats for $15 each. He needs to earn a minimum of $450 per wee
k to cover his expenses.
The inequality that represents this situation is graphed here, where x is the number of wallets sold and y is the number of hats sold.
20x + 15y ≥ 450
Determine which points are valid solutions and which are invalid, and then drag them to the correct location on the table.

Answer:
Volume = cubic inches
Step-by-step explanation:
A cube is the 3D version of a square. Since one side length is x inches, all the other side lengths are same, x inches each.
We know,
Volume = area of base * height
THe base is a square and the area is side * side. We know each side is x, so we have:
Area of Square = Area of Base = x * x =
Now, we know height is also same side length, x, thus the volume becomes:
Volume = area of base * height
Volume =
We add the exponents when we have same base multiplied, so the expression for volume becomes:
Volume =
