Answer:
D, B, C; see attached
Step-by-step explanation:
You want to identify the transformations from Figure A to each of the other figures.
<h3>a. Translation</h3>
A translated figure has the same orientation (left-right, up-down) as the original figure. Figure D is a translation of Figure A. The arrow of translation joins corresponding points.
<h3>b. Reflection</h3>
A figure reflected across a vertical line has left and right interchanged. Up and down remain unchanged. Figure B is a reflection of Figure A. The line of reflection is the perpendicular bisector of the segment joining corresponding points.
<h3>c. Rotation</h3>
A rotated figure keeps the same clockwise/counterclockwise orientation, but has the angle of any line changed by the same amount relative to the axes. Figure C is a 180° rotation of Figure A. The center of rotation is the midpoint of the segment joining corresponding points. Unless the figures overlap, the center of rotation is always outside the figure.

<em>Additional comment</em>
The center of rotation is the coincident point of the perpendicular bisectors of the segments joining corresponding points on the figure. It will be an invariant point, so will only be on or in the figure of the figures touch or overlap. In the attachment, the center of rotation is shown as a purple dot.
8,425 ÷ 10.25 = 821.95
You would round up so to earn $8,425 you would need to work 822 hours
Answer:
There are 40 students in the class.
Step-by-step explanation:
We are given the following in the question:
Percentage of class that failed = 15%
Percentage of class that made mistakes but did not fail = 25%
Number of students that got perfect score = 24
Percentage of students that got perfect score =

Let x be the total number of students in the class.
Then, we can write:

Thus, there are 40 students in the class.
83 x 72 = 5,976. 82 x 73 = 5,986. The way to do this is to take the two biggest numbers and use them in the tens place. Then take the other numbers and put them in the ones space. Then switch the ones slot numbers around to get two different numbers over 5000.
12a. First expressing as a fraction, Shan has 12/32 books from his favorite author, so:
12/32=3/8=0.375 books from his favorite author
12b. Because the decimal 0.375 isn't a periodical decimal, so it would be a terminating decimal.
