Step-by-step explanation:
Answer: 60=5(7+x)
X= 5
Step-by-step explanation:
60 is the total amount of songs so it’s going to be divided into 5 different playlists. And those playlists are going to have 7 older songs plus the amount of new songs.
Because there are two variables, we cannot solve for an exact value of s.
1.5s - 4 = t
Add 4 to both sides.
1.5s = t + 4
Divide both sides by 1.5
s = (t + 4)/1.5
Answer:
B
Step-by-step explanation:
<em>Let
be the radius of one sphere.</em>
- Volume of sphere is

Since radius is r, the height of the cylinder will be 
Also, the cylinder has the same radius as the sphere: 
- Volume of Cylinder is

Plugging in the values we get: 
<u>Ratio of volume of 1 sphere to volume of cylinder is</u>:

The ratio is 1:3
Answer choice B is right.
