Answer:
a) 3 inch pulley: 11,309.7 radians/min
6) 6 inch pulley: 5654.7 radians/min
b) 900 RPM (revolutions per minute)
Step-by-step explanation:
Hi!
When a pulley wirh radius R rotantes an angle θ, the arc length travelled by a point on its rim is Rθ. Then the tangential speed V is related to angular speed ω as:

When you connect two pulleys with a belt, if the belt doesn't slip, each point of the belt has the same speed as each point in the rim of both pulleys: Then, both pulleys have the same tangential speed:


We need to convert RPM to radias per minute. One revolution is 2π radians, then:


The saw rotates with the same angular speed as the 6 inch pulley: 900RPM

Answer:
D. The numbers distance from zero in the number line.
Step-by-step explanation:
answer : t= 6d
Kelli is running a mile in gym. She runs at a pace of 6 minutes per mile.
We change the speed to miles per minute
6 minutes per mile = 1/6 miles per minute
d is the distance that Kelli has run and t is the number of minutes passed.
Speed is 1/6 mile per minute
We know the formula distance = speed * time
distance is d, speed is 1/6 and time is t
So the equation becomes

Multiply by 6 on both sides
6d = t
t= 6d
