Find how much he will earn
we know he will earn 8 hours sofirst find how many he earns
9 per hour
8 hou
9*8=72
72+6*numberofdeliveries=155
minus 72
6*numberofdeliviers=83
divide by 6
number of delevieries=13.8
he can't make 13.8, round up to get 14

answer is 14 deliveries

To first get rid of the $9 per hour do 8 x 9 (=72). Then do 155- 72 (=83)to show how much more money needs to be made, then 83/the amount of money for each delivery- which is 6. Then the answer is rounded up from 13.83333 to 14 and the answer is 14.

Evaluate the expression when a= 4, b= - 2, and c= 7 - -> 5a - 9 (b - c)
ollegr [7]

Answer:

65

Step-by-step explanation:

Given the following question:

5a-9(b-c)
a = 4
b = 2
c = 7

In order to find the answer, we need to substitute the variables with the numbers given, and then solve using PEMDAS.

5\times4-9\times(2-7)
2-7=-5
5\times4-9\times-5
5\times4=20
20-9\times-5
9\times-5=-45
20--45
20+45=65
=65

Hope this helps.

In a raffle, 1,000 tickets are sold for $2 each. One ticket will be randomly selected and the winner will recieve a laptop compu
Kryger [21]

Answer:

$ 1.2

Step-by-step explanation:

The first thing is to define the expected value of the ticket that would be the sum of the value for all event probabilities.

That is, if you buy 1 ticket, for each participant the probabilities are:

1. 1/1000 to get a $ 1,200 item

2. 999/1000 to get nothing ($ 0).

That is to say:

(1/1000) * $ 1200 + (999/1000) * $ 0 = (1/1000) * $ 1200 = $ 1.2

Therefore, the expected value is $ 1.2, this means that in reality each participant pays $ 0.8 more than the ticket is worth
