After extensive research, a physicist has developed a way to determine the minimum stopping distance of a car. The stopping distance, s, is greater than or equal to the ratio of the square of the speed of the car, u, to twice the deceleration, d. Which of
the following inequalities represents this situation?

answer: c i think

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.

step-by-step explanation:

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
