Which angles are complementary to each other? Select all that apply.
The complementary angles are ∠1 and ∠5. The correct option is D.
What are complementary angles?Complementary angles are two angles whose measures add up to 90 degrees. In other words, if angle A and angle B are complementary, then:
A + B = 90 degrees
A = 90 - B
B = 90 - A
For example, if angle A measures 30 degrees, then angle B would measure 60 degrees to make a complementary pair. Complementary angles are often used in geometry and trigonometry to solve problems involving right triangles and other geometric shapes.
The two angles ∠1 and ∠5 have the sum of 90°. These angles are complementary to each other.

complete the equation of the line whose slope is -2 and y intercept is (0,3)
Answer:
y = -2x+3
Step-by-step explanation:
This is assuming you want the answer in slope-intercept (y = mx+b)
You need to know:
y = The line
m = The slope
b = The y-intercept
Step 1, replace the slope (m):
y = -2x+b
Step 2, replace the y-intercept (b):
y = -2x+3
Conclusion to 'complete the equation of the line whose slope is -2 and y intercept is (0,3)': y = -2x+3

Answer:sorry its c
Step-by-step explanation:
The mean value of Keisha’s data is 1.333333.
What is Mean?The mean is the average of a set of variables in mathematics and statistics. There are several methods for computing the mean, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations),
We have the data,
0, 1, 0, 2, 2, 1, 3, 0, 4, 0, 1, 2.
So, the mean value of data is
= (0 +1 + 0 + 2 + 2 + 1 + 3 + 0 + 4 + 0 + 1 + 2)/12
= 16/12
= 4/3
= 1.33333

Matteo has &400 in his saving account. On average he spends $10 per week on buying apps. Luca has $200 in his savings account. He is saving $15 a week in order to buy a new Playstation. When will matteo and luca have the same amount of money?
Answer: By the 8th week.
Step-by-step explanation:
Let the time that matteo and luca have the same amount of money be represented by x.
The information given in the question can be formed into an equation as:
400 - 10x = 200 + 15x
Collect like terms
400 - 200 = 15x + 10x
200 = 25x
x = 200/25
x = 8
Matteo and Luca will have the same amount of money by the 8th week.

Write the equation of the circle with a center at (11,6) and a radius of 6.
Answer:
(x-11)^2 + (y-6)^2= 6^2
Step-by-step explanation:
Answer:
(x - 11)² + (y - 6)² = 36
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (11, 6 ) and r = 6, then
(x - 11)² + (y - 6)² = 6² , that is
(x - 11)² + (y - 6)² = 36

find the value of n
1/4(2n +6) = 4
Answer:
n=5
Step-by-step explanation:
1/4(2n +6) = 4
Multiply each side by 4
4*1/4(2n +6) = 4*4
(2n +6) = 16
Subtract 6 from each side
2n+6-6 = 16-6
2n = 10
Divide each side by 2
2n/2 = 10/2
n =5
Answer:
n= 5
Step-by-step explanation:
Hello! So to find the value of n, we just multiply 1/4 by the numbers inside the parentheses and then solve for n by dividing. Let's do it!
1/4 (2n + 6) = 4
0.5n + 1.5 = 4
0.5n = 4 - 1.5
0.5n = 2.5
n = 2.5 / 0.5
n = 5

The five values for a data set are: minimum=11 Lower quartile=12 Median=23.5 Upper quartile=27 Maximum=33 Where will the different sections of the box plot be located?
Answer:
The answer is "Please find the given plot which is shown in the figure".
Step-by-step explanation:
[tex]Minimum = 11\\\\Lower \ quartile = Q_1 = 12\\\\Median = Q_2 = 23.5\\\\Upper \ quartile = Q_3 = 27\\[/tex]
Boxes are between 12 and 27 [tex]\to Q_1 \ \ to \ \ Q_3[/tex]
The box divides a line at 23.5 [tex]\to Q2[/tex]
The left whisker would be 11-12 [tex]\to Minimum \ \ to\ Q_1[/tex]
The proper whisker will be 27 to 33 [tex]\to Q_2 \ \ to \ \ Maximum[/tex]
