Answer:
12 minutes
Step-by-step explanation:
![\frac{7}{6} =\frac{14}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B6%7D%20%3D%5Cfrac%7B14%7D%7Bx%7D)
![7x=84](https://tex.z-dn.net/?f=7x%3D84)
![x=12](https://tex.z-dn.net/?f=x%3D12)
So, he spent 12 minutes jogging.
Answer:
96π
Step-by-step explanation:
![v = \frac{1}{3} {r}^{2} h\pi](https://tex.z-dn.net/?f=v%20%3D%20%20%5Cfrac%7B1%7D%7B3%7D%20%20%7Br%7D%5E%7B2%7D%20h%5Cpi)
V=96π
An arithmetic sequence starts with one number and you add the common difference to the previous term to get the current term
So...
f(x)=mx+b
m=common difference
b=starting point
f(11)=125=11m+b
-
f(1)=5=1m+b
--------
120=10m
Divide both sides by 10
12=m
Your common difference is 12.
Substitute the number for the appropriate variables and solve
(ab)^2
(4×3)^2
(12)^2
12×12
144
Your answer is B.144
