Answer:
There are 9 boys and 12 girls in mrs Clark's class
Step-by-step explanation:
We are given that mrs Clark has 21 students, of which 3/7 are boys
In order to find the number of boys, we multiply 21 by 3/7 which results in 9
This means there are 9 boys and then we just simply subtract 9 from 21 in order to find the number of girls 21-9=12
therefore there are 9 boys and 12 girls in mrs Clark's class
The answer would have to be 0
We can rewrite the given time as:
- 7.03x10^15 mins
- 1.17x10^14 hours.
- 4.88x10^12 days.
<h3>
What is 4.22x10^17 seconds in minutes and hours?</h3>
First, remember that:
60s = 1 min
Then to write that amount in minutes, we just need to divide by 60, so we get:
(4.22x10^17)/60 mins= 7.03x10^15 mins
Now, remember that:
1 hour = 3600s
Then to get the time in hours, we need to divide by 3600:
(4.22x10^17)/3600 h = 1.17x10^14 hours.
Similarly, you can change to any time unit that you want, for example:
1 day = 24*3600 s
Then the time in days is:
(4.22x10^17)/(24*3600) days = 4.88x10^12 days.
And so on.

Answer:
g = 12
Step-by-step explanation:
g + 7 - 4 = 15
Combine like terms
g +3 = 15
Subtract 3 from each side to isolate g
g+3-3 = 15-3
g = 12
400 - 200 = 600.
