One revolution also corresponds to an angular displacement of 2π rad.
So, the angular velocity is
120 rev/min = (120 rev/min) * (2π rad/rev) = 240π rad/min
If each math book is 0.75 of a inch wide you would do 18 divided by 0.75= 24. 24 books width can fit into the 18 inches.
Answer:
x = 9
Step-by-step explanation:
The two angles are alternate exterior and has same measurement
15(x+1) = 150 divide both sides by 15
x + 1 = 10 subtract 1 from both sides
x = 9
12% less since faster
100%-12%=88%
88% of 4 min and 23 sec=
0.88 times 263 seconds=
=231.44=3 minutes and 50 seconds rounded
3 mins, 50 seconds
