Answer:
1.5hours
Step-by-step explanation:
Firstly in this question, we convert the time given to minutes.
Using the conversion of 60 seconds make a minute, we have 3/4 hours as 3/4 * 60 = 45 minutes. Let’s add this to a total of 3 hours which is 180 minutes. This gives a total of 225 minutes.
Now, we are told that he spends 2/5 of his time lifting weight. This is equivalent to 2/5 * 225 = 90 minutes
We convert this to hour = 90/60 = 1.5 hours
4485 square feet of grass ... 3/4 of an hour
x square feet of grass = ? ... 1 hour
If you would like to know how many square feet of grass can be fertilized per hour, you can calculate this using the following steps:
4485 * 1 = 3/4 * x
4485 = 3/4 * x /*4/3
x = 4485 * 4 / 3
x = 5980 square feet
Result: 5980 square feet of grass can be fertilized in one hour.
1.2 8 x 15 percent = 8 x .15 = 1.2
Answer:
1)
16=25%
x=100%
25x=1600
x=64
2)
6300/1260 * 100 = 20
100 - 20 = 80%
3)
Total: 40
Set desingers: 16
16/40 = 40%
4)
500*22%=110
500-110=390
