Chareese reflects figure RSUT over the y-axis and then rotates the reflected figure 180° about the origin, resulting in figure A. She states that RSUT ≅ ZYWX. Which best describes the accuracy of her congruency statement?


A: Accurate. A reflection will change the direction the vertices trace around the figure. A rotation preserves the change.

B: Accurate. A reflection preserves the direction the vertices trace around the figure. A rotation changes that direction.

C: Inaccurate. The correct congruency statement is RSUT ≅ ZXWY

D: Inaccurate. The correct congruency statement is RSUT ≅ XWYX

Answer:

B

Step-by-step explanation:

the direction of the vertices is still as it is, but when u rotate is 180 degree, the direction of the points changes. This is the same as reflecting the image over the x-axis.

17 because it goes by two
it is 17. I know this because it’s first 9 and then the next given number is 13 meaning it goes up 4. so if you go down to the one before it, it’s half of it. so it goes up 2. then when you’re at 13, you go up two. making the next one 15. then you go up two one last time and get 17z

SORRY FOR THE WRONG STEP BY STEP EXPLANATION !
I DO NO WRITE IT INTENTIONALLY
reasons: I have to answer multiples of questions at a single time
Cuz some one vote it 3 stars so I did a quick check again at the equation

So it's like this

x + 25 + 80 = 180
x = 180 - 25 - 80
x = 75 Degrees

Hope it helped ! Have a good day !

Should be 125.

80 degrees then vertical is 80 the alternate exterior angles are congruent so 80 the. Vertical again then supplementary which is 100 +25.

A large bag contains 16 red, 48 blue, and 16 green marbles. Each student in Mrs. Wynn's class randomly selects a marble, records the color, and then puts the marble back into the bag. Mrs. Wynn then reports the total number of red, blue, and green marbles selected by the entire class. Which of these statements are true? Choose all that are correct. A. Theoretically, the probability of selecting one red marble from this bag is 0.20. B. If the total number of red marbles selected is not equal to the total number of green marbles selected, then there was a mistake in selecting the marbles or recording the data. C. If there are 30 students in the class, the total number of blue marbles selected should be about 18 but may be more or less. D. If a student does not return his or her marble to the bag before the next student selects his or her marble, the theoretical probability of selecting a blue marble may be different for the next student. E. It is possible that every student selects a green marble.

Answer:

It may be D. If a student does not return his or her marble to the bag before the next student selects his or her marble, the theoretical probability of selecting a blue marble may be different for the next student. because it would be the most logical response in this case

Peter has a unique computer. The screen of the computer is a square and measures twelve inches. What is the area of the entire computer screen?

A. 144 in
B. 124 in
C. 54 in
D. 48 in

Answers

Answer:

A. 144 in

Step-by-step explanation:

Squares have congruent sides.

One side is 12 inches, so all of the other sides are 12 inches.

To find the area of a square, multiply width by height. The width is 12, and the height is also 12

12 * 12 = 144

144 in ^2

A.

If it is 12 inches, the sides are all 12 inches, so simply multiply the height and width so 12 • 12 = 144

So the area is 144 inches

What is the mean absolute deviation of a data-set?

The mean of a data-set is given by the sum of all observations divided by the number of observations.

The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.

The mean absolute deviation represents the average by which the values differ from the mean.

In this problem, the mean absolute deviation is of 1.3 inches, hence, it can be concluded that the daily rainfall volume differs from the mean by an average of 1.3 inches.

Step-by-step explanation:

10x10=100x10=1000

Answer:

314

Step-by-step explanation:

The answer would be 314 because we know that the formula for Area is time radius squared so we plug in the information stays the same as for r it is replaced with 10 inches. We start off by multiplying by the radius or 10 but before that we square it.  Squaring it is taking the number and multiplying it by itself so 10x10 giving us 100. After that we can do 3.14 x 100 to get our answer of 314.
