This is a complicated question because part of the paddle is submerged, so the effective radius is somewhat less than r=0.68 feet. We'll ignore that.
We have f=14 revolutions per minute so the tip of our paddles moves at
That's it except we'll get the result in feet per minute which we have to convert to mph.
Answer: A
That's oddly close to the radius in feet because

Answer:
the answer is forty sevan
Step-by-step explanation:
104 - 57 equals 47
-3x < 30.
When you solve for x, the answer is x>-10. This matches the graph.
Answer:
x = 20
Step-by-step explanation:
Length 6 corresponds to length 15
Length 8 corresponds to length x
15 ÷ 6 = 2.5
8 • 2.5 = 20
x = 20
2.5 is the scale factor of the small triangle to the big triangle.
