Answer:
8482.3 inches
Step-by-step explanation:
You have to find the circumference of the wheel.
If the radius is 13.5, the diameter is 27 (13.5 x 2).
C = πd
C = π × 27
C = 27π
100 rotations means 27π × 100 = 2700π
= 8482.3 inches
Let x = 0.757575... . Then
100x = 75.757575...
and so
100x - x = 75.757575... - 0.757575...
99x = 75
x = 75/99 = 25/33
2(-3y-1)+(2y+7)
Final result :
5 - 4y
Step by step solution :
Step 1 :
Step 2 :
Pulling out like terms :
2.1 Pull out like factors :
-3y - 1 = -1 • (3y + 1)
Equation at the end of step 2 :
-2 • (3y + 1) + (2y + 7)
Step 3 :
Final result :
5 - 4
Ratio 3:5:9....added = 17......the largest share will then get 9/17 of the total amount. The largest share will get 54.
So 9/17 of the total money is 54...
9/17x = 54
x = 54 / (9/17)
x = 54 * 17/9
x = 102.....so the total amount of money is 102
the smallest share gets : 3/17 * 102 = 18 <===
the middle share gets : 5/17 * 102 = 30
the largest share gets : 9/17 * 102 = 54
