Step-by-step explanation:
Variable x = number of copies
6.50 <= 0.45x
Divide both sides by 0.45
6.50 ÷ 0.45 <= 0.45x ÷ 0.45
14.4444.... <= x
No more than 14 copies
6.50 <= 0.45x
6.50 <= 0.45(14.444)

whats your question? lol
Step-by-step explanation:
David > Chris
Chris < Annie
Annie = Sarah
Sarah < David
David is out since he is taller that Chris.
Anne is out since she is taller than Chris.
Sarah is out since Anne and Sarah are the same height.
Chris is the shortest, because he is shorter than Annie and Sarah, while Sarah and Annie are shorter than David, but Chris is shorter than Annie so Sarah applies too, Chris is shorter than Anne and Sarah.
Shortest ---> Tallest:
Chris, Anne, Sarah, David
Step-by-step explanation:
V= π r^2h
^
Pi
First you need the radius, if the diameter is 10inches divide by 2 = 5 inches, that's your radius.
π(5inches)^2 times (20 inches)
firsr work out 5^2= 5x5= 25
π(25inches) times (20inches)
25x20=500π inches
500π =1,570.7963267948966192313216916397514420985
which rounds to 1,570, the first one is your answer
