Answer:
51.1 ≈ r
Step-by-step explanation:
"A bicycle wheel travels 321 in for each revolution"- means that 321 is the circumference of the wheel that is a circle.
C = 2· π· r
What is the radius of the wheel ?
321 = 2· π· r, divide both sides of the equation by 2 π
(321/2·π) = r , use calculator, solve and round the answer
51.1 ≈ r

Answer: equation = $600 + tx$8 = $640 ; t = 5 additional hours in May
Step-by-step explanation:
Equation = $600 + tx$8/hour = $640
t = ($640 - $600)/$8/hour
t = $40/$8/hour = 5 hours
Answer: Equation = $600 + tx$8 = $640 ; t = 5 additional hours in May
