Answer:
52.5 days
Step-by-step explanation:
Ten people can dig 2 acres in 7 days.
One person can dig 0.2 acres in 7 days.
Working at half the rate, one person can dig 0.1 acre in 7 days.
8 people can dig 0.8 acres in 7 days.
8 people can dig 6/0.8 * 0.8 acres in 6/0.8 * 7 days.
8 people can dig 6 acres in 52.5 days

Answer:
3 inches
Step-by-step explanation:
Given that the volume of the rectangular prism or a cylinder needs to be cubic inches. The container being made is a rectangular prism with a height of inches and length of inches.
A rectangular prism is a polyhedron with six rectangular faces.
Therefore the required width (w) needed to produce a container with a volume of cubic inches is given by:
volume of a rectangular prism = height * width * length
Substituting:
= * * w
258.75 = 11.5 * 7.5 * w
w = 258.75 / (11.5 * 7.5)
w = 3 inches
The required width is 3 inches
Answer:
option e is correct
utilization factor is 60 %
Step-by-step explanation:
given data
arrival rate = 12 students per hour
average service rate = 20 students per hour
to find out
utilization factor
solution
we know that utilization factor is percentage of time server that is
time serve is = arrival rate / average service rate
so
utilization factor is = 12 / 20
so utilization factor is 60 %
option e is correct
Answer: y=55 x=6
Step-by-step explanation: Because of the two equivalent lines in lines DE and FE we know that the angles D and F must be equal, therefore y is 55. And now we know that angles D and F add up to 110 and because all of the angles in a triangle add up to 180, angle E must equal 70.
Angle E- (11x+4)=70
-4 -4
11x=66
divide both sides by 11
x=6
