Answer:
96 people in total.
BTW its seats and I think you meant "how many"
A=1/10, b=1/12, c=1/15 (these are the rates for each worker...)
1.)
2(1/10)+4(1/12)+t/15=1
1/5+1/3+t/15=1
(3+5+t)/15=1
3+5+t=15
8+t=15
t=7
So it would take c 7 hours to finish the job.
2.)
1/40-1/60
(3-2)/120
1/120
The drain rate is 1/60. So you will need to find t when the tank is empty, while starting at 2/3 capacity...
2/3-t/60=0
(40-t)/60=0
40-t=0
t=40
It would take 40 minutes to empty the tank when it is 2/3 full.
It's the slope-point formula:
We have:
Therefore, the slope 
Perimeter = 12
2(w+l) = 12
w + l = 6
area = 8
w x l = 8
the possibility
length = 4
width = 2
i know you can draw it
Answer:
41.40
Step-by-step explanation: 36*.15=5.40, 36+5.40=41.40
