Basile [38]

Answer:

The box must be 3 inches in height

Step-by-step explanation:

In this question, we are concerned about calculating the height of the supplies box.

To be able to get the value for the volume, we need to use the mathematical formula.

Since It is a rectangular prism, the volume V = l * b * h

where l, b and h are the length, breadth and height respectively. Now , it is the measurement of the base that is l * b, hence the base area in this question is 6 * 5 = 30 inches^2

The height of the supply box is thus 90/30 = 3 inches high

Can someone help me?
ad-work [718]

Answer:

  • registration fee: $50
  • monthly fee: $80

Step-by-step explanation:

Let r and m represent the registration fee and the monthly fee, respectively. We are told that the charges are ...

  370 = r + 4m

  530 = r + 6m

This is your system of equations.

__

Subtract the first equation from the second to start the solution.

  (530) -(370) = (r +6m) -(r +4m)

  160 = 2m . . . . . . simplify

  80 = m . . . . . . . . divide by 2

Using this value in the first equation, we find ...

  370 = r + 4(80)

  50 = r . . . . . . . . . . . . subtract 320

The registration fee is $50; the monthly fee is $80.
