5 dimes = 50 cents
2 nickels = 10 cents
you have 60 cents
<span>So we want to know how much ball bearings can be made with 5.24 cm^3 if one ball bearing has a diameter of 1 cm. We know that radius r=d/2=0.5cm So the volume V of one ball bearing is: V=(4/3)*pi*r^3 so V=(4/3)*3.14*(0.5)^3cm^3=0.524cm^3. Now we simply divide the volume of steel by the volume of the ball bearing: 5.24/0.524=10. So we can make 10 ball bearings from 5.24 cm^3 of steel</span>
Answer:
if m is midpoint then AM=BM
11X-9=7x+35
4x=44
x=11
AM=11×11-9 =121-9=112
BM=112
136-28 = 108
108/2 = 54
Answer : 54
