Answer:
6 cars per hour
Step-by-step explanation:
The rate can be expressed several ways. One of them is "cars per hour". To find that rate, divide cars by hours:
(24 cars)/(4 hours) = 6 cars/hour
__
If 6 cars were washed in 60 minutes, another way to express the rate is ...
(60 minutes)/(6 cars) = 10 minutes/car
__
When you ask "what is the rate?", you need to be specific as to the rate you're interested in. Different expressions of the rate are useful for different purposes.

Answer:
sin Ф = -1 and cos Ф = 0
Step-by-step explanation:
If the angle is -pi/2 (or -90 degrees), then the radius must be 1 and the opposite (vertical) side -1. The horizontal (adjacent) side is 0.
Thus, the sine of this angle is opp/hyp = -1.
The cosine is adj/hyp = 0.
Answer:
Step-by-step explanation:
A = LW + ½πr²
A = 15(12) + ½(3.14)(12²/4)
A = 180 + 56.52
A = 236.52 m²
