Answer:
1.5 laps
Step-by-step explanation:
You can use a proportion to solve this problem.
2 minutes is to 1/3 lap and 9 minutes is to x laps.
2/(1/3) = 9/x
Cross multiply:
2x = 9 * 1/3
2x = 3
x = 1.5
Answer: 1.5 laps

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°)
Answer:
180%

A rectangle has side lengths x + 2 and x - 1. What is the perimeter of the rectangle
when x = 5?
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.

OD. trapezoid
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
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.

Need help plzzz???!?????!
Answer:
137
Step-by-step explanation:
First start with what you know. The measure of the interior angles of a triangle total to [tex]180^{o}[/tex] so 51 + 2x + x = 180, then 51 + 3x = 180, 3x = 129, so
x = 43, the exterior angle is on a straight line with x so
x + exterior angle = 180 [since they are supplementary], since x = 43 then
43 + e = 180, so e has to be 137
f(x)= 7x^3-8x+2, f'(-2)

Step-by-step explanation:
Note that all the base are the same (the variable x). You are multiplying the three like terms together. Simply add the powers together:
[tex]x^{3} * x^{4} * x^{5} = x^{3 + 4 + 5} = x^{12}[/tex]

A teacher has 36 students who were randomly assigned to 6 rows of 6 desks. She wants to survey the students
about the homework policy. Which of the following uses cluster sampling?
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.
Thus, the correct answer would be an option (A).

AA’ = BB’
AA = BB
AB = BB
A’A’ = B’B’
Answer:
AA’ = BB’
Step-by-step explanation:
Suppose that we have a point (x, y), and we apply a transformation that translates this point in a given direction, let's suppose that we translate n units in the horizontal axis, and m units in the vertical axis.
Then the new coordinates of the point will be (x+ n, x + m)
Notice that for any point (x, y) the distance between the original point and the translated point (x + n, x + m) is always the same.
D = √( (x - (x + n))^2 + (y - (y + m))^2)
D = √ ( n^2 + m^2)
Here you can see that there is no dependence with the original coordinates of the point.
So if we have a line and we translate it with a translation like the one defined above, the distance between all the points in the original line and the corresponding point in the translated line is always the same.
Then if we have the point A, and after the translation, it becomes A', the length of the segment AA' is equal as the distance between A and A'.
And exactly the same happens for B and B'.
Then if the distance between A and A', is the same as the distance between B and B', then:
AA' = BB'
Answer:
AA’ = BB’
Step-by-step explanation:
A transformation produces a mapping of points whose distances are congruent.

Answer A states, "save at least $72." If the inequality used a greater than or equal to sign this could work, yet it uses a > symbol. I would go with B & C, if you haven't chosen already.
