Answer:
150 minutes
Step-by-step explanation:
First we have to express all these fractions of an hour in minutes, then add them and get the total of minutes.
To pass these numbers in hours to minutes, we only have to multiply by 60 because one hour has 60 minutes.
3/4 h =
3/4 * 60 = 45m
5/6 h =
5/6 * 60 = 50m
11/12 h =
11/12 * 60 = 55m
to calculate the total number of minutes we have to add the 3 values that we have
45m + 50m + 55m = 150m

Answer:
k = - 2
Step-by-step explanation:
Given α and β are the zeros of x² - 6x + k = 0 , with
a = 1, b = - 6 and c = k , then
α + β = - 
= - 
= 6
αβ = 
= 
= k
Then solving
(α + β)² - 2αβ = 40
6² - 2k = 40
36 - 2k = 40 ( subtract 36 from both sides )
- 2k = 4 ( divide both sides by - 2 )
k = - 2
Answer:
Greater than 5
Step-by-step explanation:
The quotient of 5 1/2 is greater than 5 because if you convert 5 1/2 to a decimal, it becomes 5.5.
5.5 is greater than 5, so the quotient of 5 1/2 is greater than 5.
You can first do the multiplication 117* 100 (=11700) or
54 * 100 = 5400
