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.
Commutative property of multiplication is shown above. This is because no matter how you put them, the answer will still be 140.
Let the price be p. Then 1.10p = $8.25. Solving for p, p = $750 (answer)
Answer:

Step-by-step explanation:
This is the answer.
Answer:
0 The product will be smaller than both the factors.
0 There will be a zero in the tenths place.
