Answer:
3.75
Step-by-step explanation:
Set up the following ratio:
2400 watt-hours 1 day
------------------------- = ----------
9000 watt-hours x days
Then do criss-cross-apple-sauce:
x*2400=9000*1
And then solve for x:
2400x=9000
x=9000/2400
x=3.75

Step-by-step explanation:
You are correct, it should either be ∫₁² (x)² dx or ∫₀¹ (x+1)² dx.
Define rates at which the individuals paint.
Bill: x = 1/8 signs/h
Bob: y = (2 signs)/(8 h) = 1/4 signs/h
Barry: z = (4/3 signs)/(8 h) = 1/6 signs/h
The job is to paint 2 signs, working together.
In the first 3 hours, the amount painted is
(x+y+z signs/h)*(3 h) = (1/8 + 1/4 + 1/6)*3 = 13/8 signs
Remaining: 2 - 13/8 = 3/8 signs
Barry quits.
In the next 1/2 hour (30 minutes), the amount painted is
(x + y signs/h)*(0.5 h) = (1/8 + 1/4)*0.5 = 3/16 signs
Remaining: 3/8 - 3/16 = 3/16 signs
Now Bob quits.
The time for Bill to finish the job is
(3/16 signs)/(1/8 signs/h) = 3/2 h
Answer: Bill finishes the job in 1.5 hours (or 1 hour, 30 minutes)
