Benny the Barber (see Question 1) is considering the addition of a second chair. Customers would be selected for a haircut on a FCFS basis from those waiting. Benny has assumed that both barbers would take an average of 20 minutes to give a haircut, and that business would remain unchanged with customers arriving at a rate of two per hour. Find the following information to help Benny decide if a second chair should be added: Part (a): The average number of customers waiting. Part (b): The average time a customer waits. Part (c): The average time a customer is in the shop.

Answers

According to the information presented, Benny should decide not to add a second chair because the average number of clients waiting is 1 (very low), the average waiting time for a client is 10 minutes (very low), and the average time a customer is in the store is 20 minutes (very low).

According to the information, an average of 2 clients arrive at the hairdresser for every hour (60 min) and each cut takes a maximum of 20 minutes. Therefore, the hairdresser would have an average of 40 minutes busy and 20 minutes free for each hour.

Additionally, customers who must wait do not have to spend a long time waiting in the store because the maximum waiting time is 10 minutes (in the case that both customers arrive at the same time).

Below is a graph where the information of both cases is compared (with an additional chair and without an additional chair) and it is inferred that an additional chair is not necessary because the number of clients waiting and the waiting time is not high.

Answer:

False θ·θ.................

Answer:

x = -28/3

y = -51

Step-by-step explanation:

Let's solve for X first

6x + 5 = 3x - 23

-3x            -5         (like terms)

3x = -28

/3       /3               (divide by 3)

x = -28/3

y = 6(-28/3) + 5

y = -51

Answers

i think it’s 115 because 33x3 is 99 then 99+16 is 115

Answer:

115

Step-by-step explanation:

y = 3

33y + 16

So since we know what y equals, we replace y in the equation to find our answer

33(3) + 16

33 times 3

99 + 16

115

A. y = 5^x – 27

B. y = -1/5x – 27

C. y = -1/5x – 15

D. y = -5^x – 27

Answers

Answer:

D. y = -5^x – 27

Step-by-step explanation:

Find the negative reciprocal of the slope of the original line and use the point-slope formula  y − y 1 = m ( x − x 1 )  to find the line perpendicular to  − x + 5 y = 14 .

y = − 5 x − 27                         PERPENDICULAAR

A marathon is 26.2 miles long. Jarrod is running a marathon and has completed 17.75 miles. How
many more miles to the finish line?

Answers

Answer:

Jarron has 8.45 more miles to get to the finish line.

Step-by-step explanation:

All we have to do is subtract the total number of miles by the number of miles Jarron has completed.

So: 26.20 - 17.75 = 8.45

26.2 - 17.75 = 8.45

All you need is subtraction because you are finding what is left.

You can find 8.45 by using a calculator or solving in your head, it would just take longer.
