I don't really understand this question do u have a pic
Her estimate is reasonable because there are 12 months in a year. 12×40 is 480. 480 is pretty close to 474.72
Answer: My best answer would be independent
Step-by-step explanation: because you would be the one rolling the dice but you don't know what it would be landing on

Explanation:
We view the ramp as a right triangle. The hypotenuse is 4.2 and the vertical side .7, which is opposite the angle
θ
we seek.

I'm going to finish the problem but I'll note if we were actually building the ramp we don't need to know the angle; this sine is sufficient.

which I think is a pretty steep ramp for a wheelchair.
There will be another inverse sine that is the supplementary angle, around
170

, but we can rule that out as a value for a ramp wedge angle.
Answer:
2.5mph (miles per hour)
Step-by-step explanation:
Simple, 12.5/5 = 2.5 mph (miles per hour)
