The approximate area that is within range of the motion sensor is 4975 square meters
<h3>How to determine the area of the range?</h3>
The figure is not given, however the area of the range can be calculated without the figure.
The given parameters are:
Angle, ⊕ = 135°
Radius, r = 65 meters
The area of the range is calculated using the following sector area
This gives
Evaluate
A = 4974.9375
Approximate
A = 4975
Hence, the approximate area that is within range of the motion sensor is 4975 square meters

Jus go a thru z and you’ll be fine
Answer:
Step-by-step explanation:
This information provides the number of students who read a certain range of books. Those ranges are provided 0 to 4 (inclusive) 5 to 9 and 10-14.
Since 9 books or more covers two bins, this cannot be the answer.
The information doesn't offer specific values just ranges, so both the mean and median cannot be determined.
So the answer is C, the number of students who read 4 books or fewer.
<h3>Answer: RS = 16</h3>
========================================
Explanation:
The ratio QR : RS : ST is equal to 1 : 4 : 5
This means we have the following three equations
For some positive number x.
Note the ratio QR : RS : ST turns into x : 4x : 5x, which reduces to 1 : 4 : 5 when we divide all three parts by x
.
Along with those three equations, we'll also use QT = 40 as well.
Now turn to the segment addition postulate. Plug in the equations mentioned earlier, and solve for x
.
QT = QR + RS + ST
40 = x+4x+5x
40 = 10x
10x = 40
x = 40/10
x = 4
So we know that
QR = x = 4
RS = 4x = 4*4 = 16
ST = 5x = 5*4 = 20
-----------
As a check,
QR + RS + ST = 4 + 16 + 20 = 40
which is the same as QT = 40
Therefore, we've confirmed that QR + RS + ST = QT is correct and we've confirmed our answers.
