Answer:
86/5 or 17.2
Step-by-step explanation:
5 + 21/5 + 8
46/5 + 8
86/5 or 17.2
Answer:
26.3 rev/min
Step-by-step explanation:
The angular velocity (ω) is the linear velocity divided by the radius ( r= 80 feet)
ω = 220/80 = 2.75 rad/s
The angular velocity and the frequency are related by:
ω = 2π*f
2.75 = 6.28*f
f = 2.75/6.28
f = 0.438 rev/s * 60s/1min
f = 26.3 rev/min
125 %
If you divide 15 by 12 (the difference between the prices) then that's what you get :)
