Answers

Answer:

a) 60% finished the race    b) 40% did not

Step-by-step explanation:

if this is useful please make me brainliest

60 fin 40 didnot

**Explanation:** Most of the time, people use percentages to express a fraction or a portion of a whole. In fact, percent literally means "per 100" or "out of 100." So when you see 25 percent, for example, you could read it as "25 out of 100" or "25 per 100 parts." But you can also have percentages that are greater than 100 percent – and when that happens, there's at least one complete whole, or a whole number, hidden in there somewhere.

1) The bowling club at your school had a car wash last week. They washed 72 cars in 6. 5 hours. About how many cars did they wash per hour?

2) You bought two 2.5 pound bags of shrimp for $34.99. What is the unit rate of the shrimp in dollars per pound? Find the unit rate to the nearest dollar.

Answers

1) they would wash about 11 cars per hour 72/6.5
2) 13.99 per 1/2 pound 34.99/2.5
They washed 11 cars jn an hour . U do 72 divided by 6.5 to find the unit rate . And for the shrimp you do 34.99 divided by 5 and it equals 6.998 so you round to 7 . Therefore shrimp costs 7 dollars per pound
