During the two hours of the morning rush from 8 a. m. to 10 a. m., 100 customers per hour arrive at the coffee shop. the coffee shop has a capacity of 80 customers per hour. how long does the customer arriving at 10 a. m. have to wait to be served? 2 hours 1 hour 0.5 hour 0.25 hour

Time to serve the customer arriving at 10 a.m. = T × (Demand/Capacity - 1)

2 * (100/80 - 1) = 0.5

The customer arriving at 10 a.m. would have to wait 0.5 hours to be served.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
