Both angles added together equal 180 degrees.
B = 180 - 45 = 135 degrees.
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.
Answer:
Step-by-step explanation:
Given:
Number of people to be seated should be greater than 75.
Let be the number of people. So,
Now, there is a single private chef's table that can seat 3 people.
Tables bought by the owner =
Number of people seated in 1 table = 4
So, number of persons that can be seated in tables =
Now, total number of persons that can be seated in these two types of tables is the sum of 3 and
Therefore,
But,
Hence, the inequality to show the situation is:
Answer:
The blank exponent is 3
Step-by-step explanation:
It is given that n^x=1/64 where n=1/4
1/4^x=1/64
1/4*1/4*1/4=1/64, so x=3 works as a solution. You could use logarithms, but it makes things more difficult, especially in this case.
Answer: The probability of the pointer lands on red(R) both spin =
Step-by-step: The number of parts = 6
The pointer is spun twice.
To find the probability of the pointer lands on red(R) both spin.
Formula
Probability of an event = number of required outcomes ÷ the total number of outcomes.
P(A and B) = P(A)×P(B)
Now,
For one spin,
A = RED comes.
For second spin,
B = RED comes
So,
P(A) = and P(B) =
Then,
P(A and B) = × =
Hence, the probability of the pointer lands on red(R) both spin =
