Answer:
The frequency of the car is 0.0233743 laps/sec and 1.4024 laps were completed in 60 seconds
Answer:
7.5
Step-by-step explanation:
You have to divide the miles by the hours drived and then divide 60 per the miles per hour
The answer is $820.
I found this by 0.8x = 656
(Remember, a 20% discount means that it costs 80%, or 0.8, of the original price)
Then, divide 0.8 on both sides:
0.8x/0.8 = 656/0.8
This leaves you with:
x = 820
96 yards = 288 feet
speed is 288/40 - 7.2 feet/s
I believe it is by .28. you take the original number, multiply if by .28 and subtract that answer from the original answer to decrease the amount by 28%.
