Answer:
2.) 8/5
Step-by-step explanation:
a4 = 8/5
11 hours and 15 minutes because doing 2.25, which is equal to 2 hours and 15 minutes, times 5 you end up getting 11.25, and converting that to time you get 11 hours and 15 minutes.
So the total number of students is 50, and you want to find 32/50. and that is equal to 64%
To find the hourly rate, we would first need to take the total earnings and subtract the bonus. $164 - $50 = 114 This gives us the total money earned for hourly work. Then we need to add the total hours worked: 4 + 8 = 12. Lastly, we need to take the total money earned and divide it by the total hours worked: 114 / 12 = 9.50 or $9.50 per hour. The equation could look like: 4h + 8h + $50 = $165
My guess is 9 hours, because since pipe a takes 12 hours and with pipe b it takes 9, it's 12-9=3
I think.
