Answer:
Part a) 
Part b) 
Step-by-step explanation:
we have
60 rev/min
Part a) Find the angular speed in radians per minute
we know that
One revolution represent 2π radians (complete circle)
so
To convert rev to rad, multiply by 2π
Part b) Find the linear speed in inches per minute
we know that
The circumference of a circle is equal to
we have
----> given problem
substitute
Remember that
One revolution subtends a length equal to the circumference of the circle
so
To convert rev to in, multiply by 16π

Answer:69
Step-by-step explanation:
Answer:
56
Step-by-step explanation:
Given that there are 8 candidates for student government: Hal, Mary, Ann, Frank, Beth, John, Emily, and Tom.
The three candidates that receive the highest number of votes become candidates for a runoff election.
i.e. 3 persons out of 8 to be selected for becoming candidates for a runoff election.
Since order does not matter we use combinations here
3 persons out of 8 can be done in 8C3 ways
= 56
no of 3-candidate combinations possible are 56
