I will show you a way to do 1 and then you pratice with the rest and I'll check it and help you .
This is what I would do to make it easier
1. 7:15 to 11:16 then 12:05 to 6:10
- hours are on the left side-
1 - 7:15 to 8:15
2- 8:15 to 9: 15
3 - 9:15 to 10:15
4 - 10:15 to 11:15
16 - 15 = 1
4 hours and 1 minute
worked :12:05 - 6:10
1- 12:05 to 1:05
2- 1:05 to 2:05
3- 2:05 to 3:05
4 - 3:05 to 4:05
5- 4:05 to 5:05
6- 5:05 to 6:05
10 - 5 = 5
6 hours and 5 mins
4 + 6 = 10 hours
1 + 5 = 6 mins
10 hours and 6 minutes
Answer: $1150
Step-by-step explanation:





Answer:
Step-by-step explanation:
Let the first term is a and common difference is d.
<u>The nth term is:</u>
<u>We have:</u>
<u>The difference of these terms is:</u>
- (a + 8d) - (a + 5d) = 16 - 15
- 3d = 1
- d = 1/3
<u>Then the first term is:</u>
- a + 5*1/3 = 15
- a = 15 - 5/3 = 13 1/3
<u>The nth term equation is:</u>
- aₙ = 13 1/3 + 1/3(n - 1) = 1/3n + 13
<u>If the nth term is 22, find n:</u>
- 1/3n + 13 = 22
- 1/3n = 22 - 13
- 1/3n = 9
- n = 9*3
- n = 27
Answer:
b. 9.2 minutes
Step-by-step explanation:
To find the expected waiting time for a random call from the sampie given by using the formula:

number of calls (x) waiting time f(x) in minutes f(x) *(x)
0 0 0
2 3 6
4 10 40
6 15 90
8 10 80
10 6 60

Therefore:


Answer:
114
Step-by-step explanation:
Both angle 8 and angle 1 have the same measure, so angle 1 would also be 114 degrees
