Answer:
1.)41.5 2.)33.68
Step-by-step explanation:
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
To solve, you need to find the least common multiple of the denominator.
In this case, its 30.
3*9= 27/30
1*10 = 10/30
She walked 37/30 miles or 1 mile and 7/30th of a mile
Put one unit at top and other unit bottom. X for unknown
5 gallon / 20 hours = x gallons / 48 hours
Cross multiply
20x = 5*48
20x = 240
X= 12
