Answer:
<em>r=6</em>
Step-by-step explanation:
<u>Proportions
</u>
We know M is directly proportional to 
This can be written as
Where k is the constant of proportionality which will be determined knowing that when r = 4, M= 160. Substituting in the equation above:
Solving for k:
The equation is:
Now find r when M=540:
Dividing by 2.5:
Taking cube roots:
![r=\sqrt[3]{216}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B3%5D%7B216%7D)
r=6
Mixed number is just saying 3(denominator) times 1 (whole #) plus 2(numerator) which would equal 5 its like a cartwheel :)
