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

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.

Students recorded the total number of pages and chapters in each of several books on the scatterplot.







Based on the scatterplot, which is the best prediction of the total number of pages in a book with 4 chapters?

Answers

Answer:

120

Step-by-step explanation:

based on the plot the closest number to the patter seem to be around 100 but its not 90 as 90 would be below so it has to be about 12

The best prediction of the total number of pages in a book with 4 chapters could be 120 pages.

How does the dot plot work?

Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in the number line. Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing we did.

We have been given that Students recorded the total number of pages and chapters in each of several books on the scatterplot.

Based on the scatterplot, we need to find the best prediction of the total number of pages in a book with 4 chapters.

According to the scatterplot, we can see that the closest number to the pattern seems to be between 100 and 120.

Therefore, the best prediction of the total number of pages in a book with 4 chapters could be 120 pages.
