each week darins lawn service mows 90 lawns in 45 hours at a housing complex the lawns in the comples are the same size
at this rate how many hours will it take darin to mow 12 lawns? complete the table
lawns 90 12
time (h) 45 ?
To find the time it will take Darin to mow 12 lawns, we can set up a proportion.
If it takes 45 hours to mow 90 lawns, we can set up the proportion:
45 hours / 90 lawns = x hours / 12 lawns
Cross multiply to solve for x:
90x = 12 * 45
90x = 540
x = 540 / 90
x = 6
Therefore, it will take Darin 6 hours to mow 12 lawns.
The completed table would look like this:
lawns 90 12
time (h) 45 6
a bottle of orange juice contains 750 mg of vitamic c and has 6 servings a bottle of cranberry juice contains 135 mg of vitamin c and has 1.5 servings. mrs kahn wants to compare the amount of vitamin c in the juices
how many milligrams of vitamin c are in 1 serving of each type of juice?
orange juice has ? mg of vitamin c per serving
cranberry juice has ? mg of vitamin c per serving
To find the amount of vitamin c in 1 serving of each type of juice, we can divide the total amount of vitamin c in the bottle by the number of servings.
For the orange juice:
750 mg of vitamin c / 6 servings = 125 mg of vitamin c per serving
For the cranberry juice:
135 mg of vitamin c / 1.5 servings = 90 mg of vitamin c per serving
Therefore, orange juice has 125 mg of vitamin c per serving and cranberry juice has 90 mg of vitamin c per serving.
how does the amount of vitamin c in each type of juice compare? complete the statement
one serving of ? juice has ? mg more vitamin c per serving than one serving of ? juice
One serving of orange juice has 35 mg more vitamin c per serving than one serving of cranberry juice.
This can be calculated by taking the difference between the amount of vitamin c in one serving of orange juice (125 mg) and the amount in one serving of cranberry juice (90 mg):
125 mg - 90 mg = 35 mg
Therefore, one serving of orange juice has 35 mg more vitamin c per serving than one serving of cranberry juice.
