In 2/4 minutes the number of
revolutions a CD makes = 58 ½
<span> = 117/2</span>
Then
In 1 minute the number of
revolutions the CD will make = [(117/2)/(2/4) ] * 1
<span>
=
(117 * 4)/(2 * 2)</span>
<span>
= 117</span>
So it can seen that the CD revolves at the rate of 117 revolutions per minute. I hope this is the answer you were looking for. The procedure for solving this problem is easy for you to understand i hope.
Answer:
33 Students
Step-by-step explanation:
4:7 => 4+7 = 11 < 24 not enough

12:21 => 12+21 = 33
24 < 33 < 40

Answer:
40
Step-by-step explanation:
Angles in a circle add up to 360 degrees.
135 + 145 + x + x = 360
280 + 2x = 360
2x = 80
x = 40
