Answer:
12.5lb
Step-by-step explanation:
5lbs+6lb=11lb
11oz+12oz=1.5lbs
11lb+1.5lb=12.5
9^2 + 12^2 = 225. the square root of 225 is 15. x=15
He would need to exercise for approximately 14 minutes to get to 120 bpm
We know that the volume is: V = 1 gallon = 231 in³
Also : r = 3 in.
The volume of a cylinder: V = r² π h
231 = 3³ · 3.14 · h
231 = 9 · 3.14 · h
231 = 28.26 h
h = 231 : 28.26
h = 8.17 ≈ 8 in
Answer: C) 8 in.
Just assuming - A = 20, B = 120, and C = 40
F = 30, G = 75, and H = 75
