Answer:
2.14
Step-by-step explanation:
|PR| = |PQ| + |QR|; |PQ| = |QR| conclusion |PR| = 2|PQ|
|PQ| = 3y; |PR| = 42; |QR|=?
subtitute
42 = 2(3y)
6y = 42 |divide both sides by 6
y = 7
|QR| = 3(7) = 21
Based on the total of intervals vs the number of intervals Amy attended her CA percentage is 75%
<h3>What is the CA percentage?</h3>
The CA percentage measures the commitment of an employee to be logged in during the intervals that were assigned to him/her to work.
In this way, the CA percentage is equal to 100% if the employee worked as scheduled. Moreover, this percentage can be affected by factors such as:
- Technical issues.
- Human errors.
In the case of Amy, there is a total of 12 intervals and it is known:
- She had a technical issue that prevented her from working, but this was reported so it is unlikely this is considered in her CA.
- She missed three intervals because she looked at her schedule wrong.
Based on this information, let's calculate her CA:
- 12 intervals = 100%
- 9 intervals = x
- x = 9 x 100 / 12
- x = 900 / 12
- x = 75%

Answer: 116.93ft^2
Explanation: find the area of the circle
A= pi•r^2
A=(3.14)•1.5^2= 7.07
Then find the area of the rectangle
A=L•W
A=15.5•8=124
Then do 124-7.07=116.93
You have to subtract the area of the circle from the area of the rectangle because the circle is not shaded in
