Amanda can jog 18 miles in 5 hours.
At this rate, how many miles can Amanda jog in 4 hours?
To solve the problem, we need to use a proportion:
distance/time = distance/time
We know Amanda can jog 18 miles in 5 hours, so we can write:
18/5 = distance/4
To solve for distance, we can cross-multiply:
5 x distance = 18 x 4
5 x distance = 72
distance = 72/5
distance = 14.4
Therefore, Amanda can jog 14.4 miles in 4 hours at this rate.
In the United States, 13 out of every 20 cans are recycled.
What percent of cans are recycled?
To find the percent of cans that are recycled, we can use the proportion:
recycled cans/total cans = percent/100
We know that 13 out of every 20 cans are recycled, which means that for every 20 cans, 13 are recycled. Therefore, we can write:
recycled cans/20 = 13/20
To solve for the percent, we can cross-multiply and simplify:
recycled cans = (13/20) x 20
recycled cans = 13
So out of every 20 cans, 13 are recycled. To find the percent, we can divide 13 by 20 and multiply by 100:
percent = (13/20) x 100
percent = 65
Therefore, the percent of cans that are recycled is 65%.
Write an equation to represent the following statement.
j is 25 more than 3.
Solve for j.
The equation would be:
j = 3 + 25
To solve for j, we simply add 3 and 25:
j = 28
Therefore, the value of j is 28.
