Select each transformation that carries a square onto itself.

A
A rotation of 180 degrees clockwise about one of the square's vertices.

B
A rotation of 90 degrees clockwise about the square's center.

C
A reflection over one of the square's sides.

D
A rotation of 180 degrees clockwise about the square's center.

E
A reflection over one of the square's diagonals.

Answers

Answer: E B D

Step-by-step explanation: I did a test

Transformation involves moving a shape from one position to another. The transformation that carries the square onto itself is:

A rotation of 90 degrees clockwise about the square's center. A rotation of 180 degrees clockwise about the square's center. A reflection over one of the square's diagonals.

For the square to carry itself onto itself, it must either be rotated or reflected.

For reflection:

It must be reflected across any of its diagonal

For rotations:

It must be rotated through its center, around multiples of 90 degrees (i.e. 90, 180, 270, 360.....)

Hence, the correct options are: B, D and E

An 80 metre long train crosses a 120 metre long platform in 20 seconds, what is the speed of the train per hour?​


ans:
Total distance= length of train + length of platform

I.e 80+120= 200 m but need in kmph so 0.2 km

Time = 20 second but need in hours so 20/(3600)= 1/(180)

Speed = distance / time = 0.2*180= 36 kmph

Step-by-step explanation:

The round off to the number at three decimal places will be 8.513.

What is rounding off the numbers?

When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.

A number can be rounded off to its lower value if the number after the decimal is between 0 and 4. The number will be rounded off to its higher value if the number after it is between 5 and 9.

During your morning workout, you run for 20 seconds for every 3 seconds you sprint. Determine the constant of proportionality for the ratio between the number of seconds you run and the number of seconds you sprint.​

Answers

Answer:

Constant of proportionality; k = 20/3

Step-by-step explanation:

Let running be A and sprinting be B.

Now, we are told that you run 20 seconds for every 3 seconds you sprint.

This means that is directly proportional to B and written as; A ∝ B.

Now, constant of proportionality is simply the ratio between 2 quantities that are directly proportional.

Thus, A = kB

Where k is the constant of proportionality

Plugging in the values of A and B we are given, we have;

20 = 3k

Divide both sides by 3 to get;

k = 20/3

Graph the equation 2x−y=9 by plotting points.

Answers

Answer:

y=2x-9

Step-by-step explanation:

2x-y=9

-2x     -2x

-y=-2x+9

-y/-y= -2x/-y+9/-y

y=2x-9

The required graph of equation 2x - y = 9 by plotting points is attached below.

To graph the equation 2x - y = 9 by plotting points, we can choose different values of x, solve for y, and then plot the corresponding points.

Here is a table of values:

x | y

0 | -9

1 | -7

2 | -5

3 | -3

4 | -1

5 | 1

Using these values, we can plot the points (0, -9), (1, -7), (2, -5), (3, -3), (4, -1), and (5, 1) on a graph.

The x-axis represents the values of x, and the y-axis represents the values of y. Connect the plotted points with a straight line to represent the equation 2x - y = 9.

Thus, the required graph of equation 2x - y = 9 is attached below.

A regular pentagon (5 sides) is rotated about its center. By which angle could the pentagon be rotated so that it is mapped onto itself?
A
45 degrees

B
60 degrees

C
72 degrees

D
90 degrees

Answers

Answer: Your answer is C, 72 degrees.

Step-by-step explanation:

A pentagon is a polygon with 5 vertices. A polygon can be rotated 360 degrees in total. Since this shape has 5 vertices, it can be rotated on every vertex to get the same figure, or in other words, it being mapped onto itself. Therefore, 360 degrees divided by 5 vertices is 72 degrees.

A. Alternate interior angle theorem
B.Converse of the alternate exterior angle
theorem
C.Converse of the alternate interior angle
theorem
D.Alternate Exterior angle theorem

Answers

Answer: B . Converse of the alternate exterior angle theorem.

The converse of the alternate exterior angle proves that line d is parallel to line e which is the correct answer would be an option (C).

What are Alternate Interior Angles?

Alternate Interior Angles are defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles.

According to the alternate exterior angles theorem, if two parallel lines are intersected by a transversal, the alternate exterior angles are congruent. In light of this, the converse of the alternate exterior angle theorem would state that if the two outside angles are congruent, the lines that the transversal cuts must be parallel.

The graph indicates that the outer angles are congruent (both equal x) shows that the lines are parallel.

Therefore, the converse of the alternate exterior angle proves that line d is parallel to line e.
