To figure out how many revolutions Buddy goes in 1 minute, (60 seconds) we can use proportions
4 revolutions/11 seconds = x revolutions/60 seconds
When we cross multiply, (multiplying one numerator by the other denominator, and vice versa for the other numerator) we get
240 = 11x
divide both sides by 11 to get
21.81 = x
or 21 complete revolutions
Answer:
A. cos(60°)
Step-by-step explanation:
sin(30 degrees) = 0.5

cos(90°) = 0
sin(60°) = √
cos(30°) = √
so it's A.
