Two pulleys, one with radius 3 inches and one with radius 6 inches, are connected by a belt. if the 3 dash inch pulley is caused to rotate at 4 revolutions per minute, determine the revolutions per minute of the 6 dash inch pulley. (hint: the linear speeds of the pulleys are the same, both equal the speed of the belt.)

The angular speed of the 6 inch pulley is 2 revolutions per minute.

Step-by-step explanation:

Consider the provided information.

Two pulleys, one with radius 3 inches and one with radius 6 inches, are connected by a belt. If the 3 dash inch pulley is caused to rotate at 4 revolutions per minute,

It is given that r₁ = 6 in, r₂ = 3 in, ω = 4 rev/min

The angular speed of the 3 inches pulley is 4.

v₁=3×4

v₁=12

Similarly for v₂

Let the angular speed of the 6 inches pulley be ω.

Then its linear speed v₂ is:

v₂=6ω

Equate the linear speed of the pulleys as shown.

v₁=v₂

12=6ω

ω=2

Hence, the angular speed of the 6 inch pulley is 2 revolutions per minute.

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
