The answer would be 24x=c
Theres roughly 53 weeks in a year (rounded up) that times two would be 106 weeks, take that times 15 and you would have 1,590 dollars (again this was rounded up if your looking for exact it would be wrong)
it would of course be much closer to 1,564 if it wasn't rounded
It would take 24 mins to drive 28 miles going 70mph
He had 44 books before the purchases because 12% of 50 is 6 and 6-50 is 44
If each spoke reaches from the center of the wheel to its rim, then that means that each spoke is as long as the radius.
To calculate radius:
C=2πr
π=3.14
C=42 inches
42=2(3.14)r
2*3.14=6.28
42=6.28r
Divide 42 by 6.28
42/6.28=6.68
length of each spoke is 6.68 inches.
