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

Answer:
Step-by-step explanation:
3y=7x+2

one pair is (1,3)
go on adding 3 in x=1,you get corresponding value of y.
x=4,y=10,(4,10)
and so on .
