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)
Answer:
The answer for this question is Quadrant III
Answer:
110 feet
Step-by-step explanation:
Given that,
Length of the rectangular garden = 9 1/4 feet = 37/4 feet
Width of the rectangular garden = 4 1/2 feet = 9/4 feet
We need to find the total length of fencing Mark needs to surround all 4 gardens.
The length for 1 garden = perimeter of the garden
The length for 4 garden = 4×perimeter of the garden
= 4×2(l+b)
Hence, 110 feet is the total length of the fencing Mark needs to surround all 4 gardens.
