Answer:
52
Step-by-step explanation:
39, 40, 44, 49, 50, 54, 56, 61, 62, 68
39, 40, 44, 49, <u>50, 54,</u> 56, 61, 62, 68
= = 52
5) x + 5.4 < -1.6
x < -1.6 - 5.4
x < -7
6) x + 7.5 > -2.5
x > -2.5 - 7.5
x > -10
7) 3 ≤ 1/3 + x
x ≥ 3 - 1/3
x ≥ 5/3
2.802691 revolutions per second
You can round to the nearest whole number making it 3 revolutions per second
2%, 0.2, 1/2
0.2 = 0.20 = 20%
1/2 = 0.50 = 50%
2% = 0.02
