Answer: EK's relationship to EL is perpendicular.
Step-by-step explanation: Two geometric objects are perpendicular if they intersect at a right angle (90 degrees or π/2 radians)
Likewise, you can see EK and EL are intersecting at a right angle, so they are in fact perpendicular.

Answer: q=70°
Step-by-step explanation: 52°+58°+q=180°

so q=70°
52+58 gives you 110.
180 is the half of a full rotation, so the straight line is 180 degrees.

yolanda measures the depth of the water in a reservoir. In one week the depth changes from 2,366.74ft to 2,354.63.ft. what rational number represents the average change in the depth each day? Show your work.
Answers
Answer:
Step-by-step explanation:
To find the average change in depth each day, we need to divide the total change in depth by the number of days.
Total change in depth = 2,366.74 - 2,354.63 = 12.11 ft
Number of days = 7
Average change in depth each day = Total change in depth / Number of days
= 12.11 / 7
= 1.73 (rounded to two decimal places)
Therefore, the rational number that represents the average change in depth each day is 1.73 ft per day.

Find the perimeter and the area of the polygon with the given vertices.
A (12,2), B (12,13), C (15,13), D (15,2)
The perimeter is __ units.
The area is __ square units.
Answers
Answer:
Step-by-step explanation:
As points A and B have same x-coordinate, length of AB will be given by the difference of y-coordinate
AB = 13 - 2 = 11 units
As points C and D have same x-coordinate, length of CD will be given by the difference of y-coordinate
CD = 13 - 2 = 11 units
As points B and C have same y-coordinate, length of BC will be given by the difference of x-coordinate
BC = 15 - 12 = 3 units
As points A and D have same y-coordinate, length of AD will be given by the difference of x-coordinate
AD = 15- 12 = 3 units
AB = CD = 11 units
BC = AD = 3 units
So,ABCD is a rectangle
Area = 11 * 3 = 33 square units
Perimeter = 11+11+3+3 = 28 units
Answer:
Solution :-At first
Length of AB = 13 - 2 = 11 cm
Length of CD = 13 - 2 = 11 cm
Length of BC = 15 - 12 = 3 cm
Length of AD = 15 - 12 = 3 cm
Now
Perimeter = 11 + 11 + 3 + 3
Perimeter = 22 + 6
Perimeter = 28
Area = 11 × 33 = 33 cm

Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

What is the biggest whole number smaller than the perimeter of any triangle with a side of length 5.6 and a side of length 19.7?
Answers
Answer:
50
Step-by-step explanation:
The perimeter of a Triangle is the sum of it's 3 sides.
We are given two sides here which is side length 5.6 and a side of length 19.7
Let's us represent the third side as x
Therefore
x + 19.7 + 5.6 = Perimeter of the triangle
We would have this equation
But it is important to know that every side of a triangle must be less than the sum of the other two sides, hence
x < 19.7 + 5.6
x < 25.3
Adding 25.3 to both sides to make the left side equal to the perimeter
perimeter = x+25.3 < 25.3 + 25.3 = 50.6
Therefore, 50.6 is the smallest whole number that is larger than the perimeter of the triangle in the question above.
Therefore, the biggest whole number smaller than the perimeter of the above triangle is 50
Answer:
39
Step-by-step explanation:
25.3<x>14.1
Because 5.6 +19.7=25.3
Because 19.7-5.6=14.1
And 25.3+14.1=39.4

A circle has a diameter of 8 inches. What is the area of this circle? Use 3.14 for pi.
(100 POINTS I NEED THE ANSWER SO I PASS THIS YEAR)
Answers
Given that a circle has a diameter of 8 inches and we are required to find its area using 3.14 as pi.
We know that the formula for calculating the area of a circle is A = πr², where A is the area, π is the mathematical constant pi (approximately 3.14), and r is the radius of the circle.
Since we are given the diameter of the circle, we can calculate its radius using the formula: radius (r) = diameter/2
Therefore, the radius of this circle is: r = 8/2 = 4 inches
Now, we can calculate the area of the circle using the formula: A = πr² Substituting the value of r, we get: A = 3.14 x 4² A = 3.14 x 16 A = 50.24 square inches
Therefore, the area of the circle is 50.24 square inches.
The answer is:
50.24 in²Work/explanation:
The formula for the circle's area :
\(\sf{A=\pi r^2}\)
where :
A = areaπ = 3.14r = radiusWe know the diameter, but the radius is one-half of that, so the radius is :
Radius = Diameter ÷ 2 = 8 ÷ 2 = 4 inchesHere's a diagram for better understanding:
\(\setlength{\unitlength}{1.1cm}\begin{picture}(0,0)\thicklines\qbezier(2.3,0)(2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,-2.121)(0,-2.3)\qbezier(2.3,0)(2.121,-2.121)(-0,-2.3)\put(0,0){\line(1,0){2.3}}\put(0.5,0.3){\bf\small 4\ in}\end{picture}\)
Now, plug in the data:
\(\large\begin{gathered}\bf{A=\pi r^2}\\\\\bf{A=3.14\times4^2}\\\\\bf{A=3.14\times16}\\\\\bf{A=50.24\:in^2}\end{gathered}\)

L is in meters whereas B and H are in cm
