Answer: 1008 revolutions
Step-by-step explanation:
1 revolution is equal to 
To find how many revolutions the wheel makes, you must divide the distance traveled in the race between the circumference of the wheel
You must first convert 62.8318 in to meters.
We know that 1 inch is 0.0254 meters
Then


Finally The wheel made 1008.21 revolutions
9y+7 + 7y-19 = 180
Y =12 degrees
No because 2/3 to 3/5 and 3/5 to 5/7 arent proportional.
answer
8/25
Step-by-step explanation:
so you would keep the first fraction (2/15) then you would change the symbol then you would flip the other fraction (5/12). then you would multiply 2*12=24 and 15*5=75. then you would simplifie it. it would be 8/25.
