Step-by-step explanation:
GIven
x: number of nickels
y: number of quarters
A nickel = $0.05
A quarter = $0.25
then we have the system of equations
0.05*x + 0.25*y = 11.90
x + y = 74
Which can be solved applying any of known methods. Then, the solution is
x = 33
y = 41

Answer:
30 inches
Step-by-step explanation:
We know that the formula for calculate the volume of a cube is:
∨=8³
Where "s" is the length of each side.
Since the volume of each cube-shaped box is 125 cubic inches, we can find "s":
125 in³=8³
∛125 in³=8
8=5 in
We know that the display has six layers of boxes, then , to calculate the height of the display, we can multiply the value of "s" obtained before by 6.
Then:
height= (5 in)(6)=30 in
