For #3, it's 5.4 because you divide the total amount of money made by the amount of money earned per hour.
49.95/9.25=5.4 hours
B the phrasing of the question suggest a bias against classical music
that is the answer because they are assuming that no teens like classic music, which is just an opinion, which is bias :)
If we need to choose the closest answer from the above given ones it is 6471.
SOLUTION:
Diameter(d)= 8
Radius(r)= d/2=8/2 =4,,
Height of cylinder (h)= 12
So,
Volume of cylinder = Pi r^2*h
=22/7 * 4^2 * 12
=4224/7
=603.42,,
You could find the difference on the internet if not found tell me and I would explain for you
1/5, 5/8, and 2/3 are the answers from least to greatest. When divided out, 1/5 = .2, 5/8 = .625, and 2/3 = .66666 repeating. Good luck!
