Step-by-step explanation:
The formula for calculate the area of a rectangle is:
Where "l" is the lenght and "w" is the width.
You know that the ratio of the sides of the rectangular window is:
Then, let be the width (in inches) of the rectangular window and
the lenght (in inches) of the rectangular window.
Knowing that the area of the window is 2,720 square inches, you can know that:
Now you must solve for "x" in order to find the width:
Finally, the lenght is:
Answer:
Time taken to process 20 students is 100 minutes.
Step-by-step explanation:
Given that:
Students are going through a three-step process to obtain their ID cards.
Let Have a table below illustrating what the question means:
Unit Number of Number of
<u> servers minutes spent</u>
Registration 1 2
desk
Cashier 3 10
ID processing 4 20
<u>station </u>
Demand Rate = 0.5 student per minute
To calculate how long it take to process 20 students assuming the system is full; we need to run through the following process:
The Capacity of each of the server at three-processes is calculated as;
Capacity = Number of students served per minute
At the Registration desk
Number of minutes spent to serve 1 student = 2 minutes
Number of servers to be = 1
Therefore, the Capacity=
= 0.5 students per minute
At the Cashier Unit
Number of minutes spent to serve 1 student = 10 minutes
and we have number of servers to be = 3
Thus, the Capacity =
= 0.3 students per minute
Over to the ID processing station
Number of minutes spent to serve 1 student = 20 minutes
Number of servers = 4
The capacity=
= 0.2 students per minute
In the three-step process, the bottleneck process is the ID processing stations and this process also have the highest time to serve 1 student.
As such, the process capacity is equivalent to the bottleneck process
Process Capacity = 0.2 students per minute
As we know that our demand rate = 0.5 students per minute
Since, the demand rate is higher than the Process capacity, the number of students served per minute will still be:
Number of students served per minute = 0.2
Time taken to serve 1 student = 1 / 0.2 = 5 minutes
Time to process 20 students = 5 × 20 =100 minutes.
