Answer:
12 cleaners
Step-by-step explanation:
8 cleaner can clean in 3 hours = 1 office
1 cleaner can clean in 3 hours =
part of job
1 cleaner can clean in 1 hours =
part of job
Let the number of cleaner required to finish the job in 2 hours = x
hence
x cleaner can clean in 1 hours =
part of job
x cleaner can clean in 2 hours =
part of job
Hence




Hence we need 12 men to complete the same job in 2 hours
Step-by-step explanation:
i think a is 50,000? if you go along the x axis until you get to 40 and then go up and see where the blue line is the blue line is on 50,000
Supplementary angles need to add up to 180 degrees.
Subtract Y from 180:
X = 180 - 156 = 24
X = 24 degrees
