The correct answer is 37.5.
Answer:
E. 2.
Step-by-step explanation:
The sphere will have a diameter equal to the side length of the cube.
The side length of the cube is ∛64 = 4 so the diameter of the sphere = 4.
The radius = 1/2 * 4 = 2.
For the answer to the question above,
and we are told that there are "four times as many quarters as nickels"
this translates to
q = 4n
0.05n + 0.25q = 2.10
and
q = 4n
are your two equations that could be used to solve this problem
if you would like to know how many nickels and how many quarters there are, plug in q = 4n into the first equation and get
0.05n + 0.25(4n) = 2.10
then I would stop here
because I didn't see the choices. So the answer is 4n
