Answer:
A, C, and E
Step-by-step explanation:
for a shape to be congruent it must be the same size and shape so
A would be correct because it only changes the position of the shape.B would be incorrect for it is dilated which changes its shape.C is correct because it also only changes the position.D is incorrect because it dilates the shape which changes the size.E would be the last correct answer because it keeps the size and shape and only changes the position.Thus your answer is A, C, and E

A pair of parallel lines is cut by a transversal. What are the measures of the two marked angles?
CHOICES
40 degrees and 40 degrees
40 degrees and 140 degrees
65 degrees and 115 degrees
75 degrees and 105 degrees
Answer:
Let us mark the points R and S on line p, T and U on line q, A and B on line l and C and D on line m.
Suppose the lines p and q intersect the line l at K and L respectively and line m at N and M respectively.
Since, AB is a straight line and ray KN stands on it, then
∠NKL + ∠NKA = 180∘ (Angles in a linear pair)
⇒110∘ + a = 180∘
⇒a = 180∘ − 110∘ = 70∘
Since, line p || line q and line l is a transversal intersecting them at K and L, then
∠TLB = ∠NKA (Alternate exterior angles)
⇒b = a
⇒b = 70∘
Since, line p || line q and line m is a transversal intersecting them at N and M, then
∠CNK = ∠NML (Corresponding angles)
⇒c = 115∘
Since, CD is a straight line and ray ML stands on it, then
∠NML + ∠LMD = 180∘ (Angles in a linear pair)
⇒115∘ + d = 180∘
⇒d = 180∘ − 115∘ = 65∘

A will be equall to {2 3 4}
The value of the set A' for the set A{1,5} from the universal set will be A'{2,3,4}.
What is a set theory?The area of mathematical logic known as set theory examines sets, which are essentially collections of objects. Set theory is an area of mathematics that primarily deals with objects that are pertinent to mathematics as a whole, despite the fact that any form of an object can be gathered into a set.
Given that the universal set is U = {1, 2, 3, 4, 5}, and the set A is {1,5}. The value of the set A' will be calculated as,
U = {1, 2, 3, 4, 5
A = {1,5}
A' = {2,3,4}
Therefore, the value of the set A' for the set A{1,5} from the universal set will be A'{2,3,4}.

1/10(x + 11) = -2(8 -x)
please show your steps, will give brainliest.
Answer:
X = 1.9
Step-by-step explanation:
Distribute first!
1/10(x + 11) = -2(8 - x)
1/10x + 11 = -16 - (-x)
Then simplify (if need be):
1/10x + 11 = -16 + x
Combine like terms:
11 + 16 = 1x - 1/10x
27 = .9x
Divide to get your x by itself:
27/.9 = .9x/.9
or
27/.9 = x
Solve:
X = 30
Answer:
-149/9=x
Step-by-step explanation:
Use distributive property first
1/10x +11/10= -16 +x
move x's to one side and the constants to the other
11/10= -16 +x -1/10x
11/10 -16= 9/10x
simplify the constants
-16x10/10= -160/10 + 11/10= -149/10
-149/10=9/10x
multiply by reciprocal
-1490/90=x
simplify
-149/9=x
A carton of two dozen eggs includes three with cracks. How many eggs without cracks can be expected in six dozen eggs?
Answer:
63
Step-by-step explanation:
because 2 dozens is 24, and since there are three cracked eggs in two dozens, in six dozens, which is 72 eggs, since 24 times 3 is 72, we have to multiply 3 times 3, which is nine, so 9-72,which is 73.
The number of eggs without cracks can be expected in six dozen eggs will be 63.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A carton of two dozen eggs includes three with cracks.
Crack egg = 3 / (12 x 2)
Crack egg = 3 / 24
Crack egg = 1/8
The number of non-crack eggs is given as,
Non-crack egg = (24 - 3) / 24
Non-crack egg = 7/8
Then the total number of eggs in six dozen is given as,
Total egg = 12 x 6
Total egg = 72
Then the total number of non-crack eggs is given as,
Total non-crack eggs = 72 x 7 / 8
Total non-crack eggs = 63
The number of eggs without cracks can be expected in six dozen eggs will be 63.

Which of the following best shows the associative property of addition?
a.4 + 5 = 9
b.(4 + 5) + 2 = 4 + (5 + 2)
c.4 + 5 + 2 = 2 + 5 + 4
Answer:
The answer is C: 4 + 5 + 2 = 2 + 5 + 4
Step-by-step explanation:
This is an example of the associative property of addition because the associative property of addition is described as any equation, that despite in what order your shift your equation to, the answer will stay the same. And as C shows, 4 + 5 + 2 will be rearranged to 2 + 5 + 4 and would still get the same answer, which would be 11.
The associative property of addition is represented by (4 + 5) + 2 = 4 + (5 + 2). The correct option is B.
What is associative property?
Rearranging the parenthesis in an expression will not change the outcome since some binary operations in mathematics have associative features.
The associative property is shown by the expression (4 + 5) + 2 = 4 + (5 + 2).
Solving the right-hand side:-
(4 + 5) + 2 = 9 + 2
(4 + 5) + 2 = 11
Solving the left-hand side:-
4 + (5 + 2) = 4 + 7
4 + (5 + 2) = 11
Therefore, the associative property of addition is represented by (4 + 5) + 2 = 4 + (5 + 2). The correct option is B.

Answer:
21. The slope is 50.
22. 0
23. y=50x
24. $2600
Step-by-step explanation:
21. The slope of the line is 50. Slope is defined as "rise over run". As the line increases, each segment moves up the y-axis by $50, and to the right on the x-axis 1 segment. (Work: 50 divided by 1)
22. The y-intercept is (0, 0), or simply 0. If you look at the graph you can see that the line crosses the y-axis at the origin. This makes the y-intercept equal to 0.
23. The slope tells you that the student makes $50 every week. The y-intercept is 0. Using the formula y=mx+b, an appropriate equation would be y=50x.
24. The equation found in problem 23 can me used to determine how much a student makes (y) after "x" weeks. Substitute 52 for x to solve for y. This becomes y=50(52). This can be simplified to y=2600. This means that after 52 weeks, the student will have made $2,600.

Question: Tyler and Kiran each started running at a constant speed at the same time. Tyler ran 4,200 meters in 30 minutes and Kiran ran 6,300 meters in 1/2 hour. Eventually, Kiran ran 1 kilometer (1000 meters) more than Tyler. How much time did it take for this to happen?
(I'll give 12 points and I'll name you brainlist.
Answer:
14 and 2/7 minutes, or 100/7 minutes
Step-by-step explanation:
To begin with, supposed the rate at which Tyler and Kiran are running are variables T and K. We can come up with the equations
30T= 4,200 and
30K= 6,300.
Where 30 is the number of minutes, multiplied by the rate at which they are running to equal the total distance ran. We can isolate the variables by dividing both sides of both equations by 30, resulting in Tyler's speed of 140 meters per minute and Kiran's speed of 210 meters per minute.
We can then plug these values into a final equation where x is the amount of time taken for Kiran to run 1 km more than Tyler
We end up with this: 210x= 140x+1000
Solve first by subtracting 140x from 210x to get 70x, and then divide both sides by 70. This isolates x and you get a final answer of 14 2/7 minutes, or 100/7 minutes
And sorry I couldn't get this to you in the 5 minutes you needed, but I hope this at least helps you understand the concept :')
It will take 14 and 2/7 minutes, or 100/7 minutes, for this to happen.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
To begin, consider Tyler and Kiran's running rates to be variables T and K. We can create the equations.
30T= 4,200 and
30K= 6,300.
Where 30 is the number of minutes multiplied by the speed of running to equal the total distance run. By dividing both sides of both equations by 30, we can isolate the variables, obtaining Tyler's speed of 140 meters per minute and Kiran's speed of 210 meters per minute.
We have to substitute the value into a final equation where x is the time it takes Kiran to run 1 km further than Tyler.
We end up with this: 210x= 140x+1000
To begin, remove 140x from 210x to get 70x, then divide both sides by 70. This isolates x, obtaining a final result of 14 2/7 minutes, or 100/7 minutes.
Thus, It will take 14 and 2/7 minutes, or 100/7 minutes, for this to happen.
