Using proportions, it is found that the angular velocity at the tip of the blade is of 753.98 radians per minute.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Each revolution has
radians, hence in one minute, the 120 revolutions will have a measure in radians of:
M = 120 x 2pi = 240pi = 753.98
Hence the angular velocity is of 753.98 radians per minute.

Answer:
see explanation
Step-by-step explanation:
(b)
30n - 12 ( factor out the gcf 6 from each term )
= 6(5n - 2) ← in factored form
(c)
6x + 9y ( factor out the gcf 3 from each term )
= 3(2x + 3y) ← in factored form
