what is the unit rate if 5 bags of chip cost a total cost of 35.22? round your answers to the nearest hundredth.
the unit rate for bags of chips per dollar is___bags per $.
the unit rate per bag of chips is $_____per bag.
To find the unit rate for the number of bags of chips per dollar, you divide the number of bags by the total cost. For the unit rate per bag of chips, you divide the total cost by the number of bags.
Unit rate for bags of chips per dollar:
Number of bags: 5
Total cost: $35.22
Bags per dollar = Number of bags / Total cost
Bags per dollar = 5 / 35.22
Now we calculate this and round to the nearest hundredth:
Bags per dollar ≈ 0.142 (rounded to the nearest hundredth)
Unit rate per bag of chips:
Total cost: $35.22
Number of bags: 5
Cost per bag = Total cost / Number of bags
Cost per bag = 35.22 / 5
Calculate this and we get:
Cost per bag ≈ $7.04 (rounded to the nearest hundredth)
So the unit rate for bags of chips per dollar is approximately 0.14 bags per $, and the unit rate per bag of chips is $7.04 per bag, when rounded to the nearest hundredth.
Each pencil costs the same price. What is the price for 1 pencil?
6 pencils for $1.92
7 pencils for $2.24
8 pencils for $2.56
9 pencils for $2.88
The cost for 1 pencil is $____.
To find the cost for one pencil, you can take the total cost for any number of pencils and divide it by the number of pencils in that group. The prices given for different numbers of pencils should all derive the same unit price since each pencil costs the same price. Let's calculate the cost for one pencil using the first set of numbers:
6 pencils for $1.92:
Cost per pencil = Total cost / Number of pencils
Cost per pencil = $1.92 / 6
Calculate this:
Cost per pencil = $0.32
To confirm that the cost for one pencil is consistent among the options, let's check one more:
7 pencils for $2.24:
Cost per pencil = Total cost / Number of pencils
Cost per pencil = $2.24 / 7
Calculate this:
Cost per pencil ≈ $0.32
The results should be the same regardless of which set of numbers you use. Since we found that the cost per pencil is $0.32 from two different sets, we can confidently say that the cost for one pencil is $0.32.
David has 444 gallons to water his
45 square foot garden. How much water would David have to evenly distribute for each square foot of his garden? Round your answer to the nearest tenth.
____gallons per square foot
To determine how much water David would have to evenly distribute for each square foot of his garden, we divide the total amount of water by the total square footage of the garden.
Total amount of water: 444 gallons
Total square footage of the garden: 45 square feet
Water per square foot = Total amount of water / Total square footage
Water per square foot = 444 gallons / 45 square feet
Calculating this gives us:
Water per square foot = 9.86666666667 gallons per square foot
Rounded to the nearest tenth, David would have to evenly distribute approximately 9.9 gallons per square foot.
John runs a 8.5 mile long race in 2 hours. What is John's mile per hour average? Round your answer to the nearest tenth.
___m.p.h
To calculate John's average speed in miles per hour (m.p.h), we divide the total distance run by the total time taken to run that distance.
Total distance: 8.5 miles
Total time: 2 hours
Miles per hour (m.p.h) = Total distance / Total time
Miles per hour (m.p.h) = 8.5 miles / 2 hours
Calculating this gives us:
Miles per hour (m.p.h) = 4.25 miles per hour
Rounded to the nearest tenth, John's mile per hour average is 4.3 m.p.h.
thats wrong
Apologies for any confusion. Let's review the calculation:
To find John's average speed in miles per hour, we divide the total distance run by the total time taken:
Total distance: 8.5 miles
Total time: 2 hours
Miles per hour (m.p.h) = Total distance / Total time
Miles per hour (m.p.h) = 8.5 miles / 2 hours
Calculating this gives us:
Miles per hour (m.p.h) = 4.25 miles per hour
Since you said the previous answer was wrong, and we calculated 4.25 m.p.h, we need to check our calculation again. However, 8.5 miles divided by 2 hours is definitely 4.25 miles per hour. The correct average speed for John, based on these numbers, is 4.25 m.p.h.
If you are looking for a rounded answer to the nearest tenth, 4.25 miles per hour is already rounded to the nearest hundredth and doesn't change when rounded to the nearest tenth. So the answer is:
4.25 m.p.h.
