R = 11-2m
S = n+5
T = -m-3n+8
---------------------------
Add up S and T to get...
S+T = (n+5)+(-m-3n+8)
S+T = n+5-m-3n+8
S+T = -m+(n-3n)+(5+8)
S+T = -m+(1n-3n)+(5+8)
S+T = -m+(-2n)+(13)
S+T = -m-2n+13
---------------------------
Subtract that result from R
R - [S + T]
11-2m - [-m-2n+13]
11-2m +m+2n-13
(-2m+m) + (2n) + (11-13)
(-2m+1m) + (2n) + (11-13)
(-1m) + (2n) + (-2)
-m + 2n - 2
---------------------------
---------------------------
The final answer is -m + 2n - 2
Answer:
Step-by-step explanation:
volume of sphere = (4/3)πr³
Difference= [(4/3)*π*6³]-[(4/3)*π*3³]
![=\pi*[(\frac{4}{3}*6*6*6) - (\frac{4}{3}*3*3*3)]\\\\=\pi*[(4*2*6*6)-(4*3*3)]\\\\=\pi *[288-36]\\\\=252\pi](https://tex.z-dn.net/?f=%3D%5Cpi%2A%5B%28%5Cfrac%7B4%7D%7B3%7D%2A6%2A6%2A6%29%20-%20%28%5Cfrac%7B4%7D%7B3%7D%2A3%2A3%2A3%29%5D%5C%5C%5C%5C%3D%5Cpi%2A%5B%284%2A2%2A6%2A6%29-%284%2A3%2A3%29%5D%5C%5C%5C%5C%3D%5Cpi%20%2A%5B288-36%5D%5C%5C%5C%5C%3D252%5Cpi)
Answer:
5.85 years
Step-by-step explanation:
Overall number of associates employed = 117
Number of associates employed per year = 20
Average = Total number of associates employed ÷ number of associates employed per year = 117 associates ÷ 20 associates per year = 5.85 years
I use math-a-way it answers questions like that
A
120/55 will give you the time it takes him to get there. If you subtract that value from both sides, you'd have:
120/x = # hours left
From there you could easily solve his average speed home.
