The answer is approximately 11.18.
1)
We calculate the total number of new light fixtures.
Total number of new light fixtures=(24 new fixtures/1 floor)(4 floors)=
=96 new fixtures.
2)
We calculate the total number of work hours
20 minutes=20 minutes * (1 hour/60 minutes)=1/3 hour.
1 electrician-----------1/3 hour----------1 new fixture
2 electricians---------- x ------------96 new fixtures
1 elec.*1/3 hour*96 nex fixtures=2 elect. * x * 1 new fixture.
x=(1 elec. *1/3 hour * 96 nex litght fixtures) / (2 elect.* 1 new fixture)=
=16 hours.
3)
We calculate the total number of days that it take two electricians to complete the installations.
1 day-------------8 work hours
x------------------16 work hours
x=(1 day* 16 work hours) / (8 work hours)=2 days
Answer: 2 days.
There are 60 bricks in a stack 20 feet high.
2x10=20
If you multiply the 2 by 10, you have to multiply 6 by 10.
6x10=60
So if there are 6 bricks in a 2 feet high stack, there are 60 bricks in a 20 feet high stack.
Twice is how many time you have to multiply it by
Answer: 1.5
Step-by-step explanation: you have to divide 6 by 4 and you get 1.5
