Answer:
34.65 dollars
Step-by-step explanation:
multiply the 75 by .45 to get the new price
If a wheel makes a full turn, it will have traveled the entire distance around that wheel. After 3 revolutions, it should have traveled 3 times its circumfrence.
The circumfrence of a circle is equal to the diameter times pi. (about 3.14)
21 × 3.14 = 65.94 = circumfrence = 1 revolution
3 revolutions = = 65.94 × 3 = D. 197.82 in.
Explanation: 54 yards is about 162 feet, and since we are converting measurements we need this ( duh ) and 135 seconds is approximately 2.25 minutes, so what we need to do is is divide the numbers like any conversion problem: 162 divided by 2.25 is 72.
Hope this answer helps!
You can cross multiply on this and then solve.
140 / 60 = 200 / x
140x = 12000
x= <span>85.7142857143
x= 85.7</span>
Two 1/3s (2/3) and 1/6 get you 5/6 a inch
basically:
2/3+1/6=5/6
