Answer:
180° (in place of blank)
Step-by-step explanation:
GIVEN :-
∠D = 127°∠A = 75°PROCEDURE :-
∠C & ∠D are linear pair. (∵ They lie on same line)
⇒ ∠C + ∠D = 180°
⇒ ∠C = 180° - 127°
In a triangle , sum of its all interior angles equals to 180° (which is also known as "Angle Sum Property). So,
∠A + ∠B + ∠C = 180°
⇒ 75° + ∠B + (180° - 127°) = 180°
⇒ ∠B = 180° - 75° - (180° - 127°)

180%

A rectangle has side lengths x + 2 and x - 1. What is the perimeter of the rectangle
when x = 5?
Answers
Answer:
22 units
Step-by-step explanation:
The perimeter is all the sides of any polygon added up.
A rectangle has 4 sides, but we only need two sides to solve this because a rectangle has symmetry
There are two ways
Method 1:
x+2 + x-1 + x+2 + x-1 OR 2(x+2) + 2(x-1)
simplify: 2x + 4 + 2x - 2
4x +2
Plug 5 into x: 4(5) + 2
Answer: 22
Method 2:
plug in x to get the sides: 7 and 4
now add: 7 + 7 + 4 + 4 OR 2(7) + 2(4)
simplify: 14 + 8
Answer: 22
The perimeter of the rectangle when x = 5 is 22 units.
What is perimeter?Its the sum of length of the sides used to made the given figure.
The perimeter is all the sides of any polygon added up.
WE know that rectangle has 4 sides, but we only need two sides to solve because a rectangle has symmetry
Given that A rectangle has side lengths x + 2 and x - 1.
Then plug in x to get the sides: 7 and 4
Now add:
7 + 7 + 4 + 4
OR
2(7) + 2(4)
Then simplify:
14 + 8
22
Hence, the perimeter of the rectangle when x = 5 is 22.

The image is an example of which type(s) of symmetry?
A. Reflectional
B. Neither rotational ner reflectional
C. Both rotational and reflectional
O
D. Rotational
Answers
The given image of the square is an example of (C) both rotational and reflection symmetry.
What are rotational and reflection symmetry?The rotational symmetry of a shape explains why an object's shape remains unchanged when it is rotated about its own axis. If a geometric shape is rotated 180 degrees or at certain angles, either clockwise or counterclockwise, many of them seem to be symmetrical. Square, circles, hexagons, and other shapes are a few examples.A sort of symmetry that pertains to reflections is called reflection symmetry. Line symmetry and mirror symmetry are other names for reflection symmetry. If a figure has at least one line dividing it into two halves, one half is said to be the mirror image of the other half.So, the given diagram of the square satisfies the situation of both rotational and reflection symmetry.
Therefore, the given image of the square is an example of (C) both rotational and reflection symmetry.

Point NN is located at (-2,-6)(−2,−6) on the coordinate plane. Point NN is reflected over the yy-axis to create point N'N ′ . Point N'N ′ is then reflected over the xx-axis to create point N''N ′′ . What ordered pair describes the location of N''?N ′′ ?
Answers
Given:
Coordinates of point N = (-2,-6)
Point N is reflected over the y-axis to create point N ′.
Point N' is then reflected over the x-axis to create point N''.
To find:
The ordered pair that describes the location of N''.
Solution:
The coordinates of point N are (-2,-6). Point N is reflected over the y-axis to create point N ′.
[tex](x,y)\to (-x,y)[/tex]
[tex]N(-2,-6)\to N'(2,-6)[/tex]
Point N' is then reflected over the x-axis to create point N''.
[tex](x,y)\to (x,-y)[/tex]
[tex]N'(2,-6)\to N''(2,6)[/tex]
Therefore, the ordered pair for point N'' is (2,6).

y = 45 / 2x + 50
Step-by-step explanation:
The best equation for the line of the best fit would be y = 45 / 2x + 50.
The slope would be 45 / 2 and the y-intercept would be ( 0 , 50 ).
I used the points, ( 0 , 50 ) and ( 4 , 140 ) to get the equation, slope, and the y-intercept.
I used those points because they were the most accurate ones that I know for now.
Also, remember the formula is, "y = mx + b."

O Roll a fair number cube. Use the number rolled to pick a row of students. Survey every student in that row.
List the students according to their grade in the class. Survey one A student, one B student, etc.
For each row, flip a coin. If it is heads, survey all the boys in that row. If it is tails, survey all the girls in that row.
O Select a student by rolling a fair number cube twice. The first roll gives the row number, and the second roll gives
the seat number. Then repeat.

Answer:
A
Step-by-step explanation:
Edge 2021
The teacher is using a number cube to select a row of students and then surveys every student in that row, which fits the definition of cluster sampling.
What is the sampling distribution?In statistics, sampling distribution refers to the study of numerous random samples drawn from a particular population depending on a specified property. The gained data paint a clear notion of the changes in the likelihood of the outcomes determined.
Cluster sampling is a type of sampling technique in which a group or cluster of units is selected from the population and then all units within the selected clusters are included in the sample.
In this case, the teacher is using a number cube to select a row of students and then surveying every student in that row, which fits the definition of cluster sampling.

Six less than twice a number x is four

Answer:
2 x − 6
Explanation:
"Six less than.." means "Subtract 6 from".
Do not confuse this with "Six less..." which means "Subtract from 6".
Confusing, I know.
We know that "Double a number" means
2 x , where x is your mystery number.
Therefore, we have:
2 x − 6 , which translates to "6 less than 2x" or "6 less than twice a number"

Write the equation of the line, in slope intercept form, that goes through the points (6,4) and (-3,-5)
Answers
Answer:
y = x - 2
Step-by-step explanation:
Find the slope using rise over run
(y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-5 - 4) / (-3 - 6)
-9 / -9
= 1
Using y = mx + b, plug in the slope and a point to solve for b:
y = mx + b
4 = 1(6) + b
4 = 6 + b
-2 = b
Plug in the slope and b to y = mx + b
y = 1x - 2
y = x - 2
So, the equation of the line is y = x - 2
