Answer:
B. A dilation with a scale factor of 0.5
Step-by-step explanation:
A. is wrong because it is congruent transformation because reflections keep the angles and side lengths of the figure the same.
B. is right because it is NOT congruent because a dilation of any scale factor other than 1 results in a similar figure, because the side lengths are proprtional but not equivalent
C. is wrong because translations keep the angles and side lengths of the figure the same.
D. is wrong because a scale factor of 1 changes nothing about the figure.

Currently I have separators on my molars so I can have enough space for an expander. But I noticed that one of my molars has shifted a lot to the side where it’s uncomfortable to eat or bite down. And I’m not sure if it’s suppose to shift to the side or not
Is that normal?-
Answers
Answer:
Yes I think
Step-by-step explanation:
I went through the braces process a few years ago and I got an expander. Your separator is probably making room for something meaning your teeth will probably move. Im no professional so Id say call into the office tomorrow or asap. And for the pain use whatever pain meds they allow (normally ibprophen ot tylenol) (sorry for spelling)

The area of the figure is ___ square units.
Answers
Answer:
26 square units
Step-by-step explanation:
We are given a diagram and are asked to find the area of the figure in square units.
To solve, take in mind that we need to multiply the sides given.
Area is L * W, therefore, we know that our length is 5 by 2 units, while our width is 3 by 2 units.
First start with the length, since it is 5 by 2 we multiply 5 and 2 :
5 * 2 = 10
Then with the width, since it is 3 by 2, we can multiply 3 and 2 :
3 * 2 = 6
Then do the length again since the bottom part of the diagram needs to be included, it is also 5 by 2 :
5 * 2 = 10
Add all these together to get your answer :
10 + 6 + 10
16 + 10
26 square units.

3. There are 6645 students at Tech Middle School, and
20% of the stredents are 7th graders.
How
many
Students are 7th graders?
Answers
Answer:
.20
Step-by-step explanation:
The word percent literally means "Out of 100". With that being said, 20% can be written as a fraction, mixed number or whole number as follows: 1/5 (fraction), 20/100 (mixed number) or .20 (whole number).
Answer:
1329 students
Step-by-step explanation:
20/100 ×6645
Reduce the fraction 20/100 with 20
So..20 goes into 20 1 time and 20 into 100 5 times
1/5×6645
Use 5 as the greatest common factor now
so...5 into 5 goes 1 time and 5 into 6645 goes 1329
1/1 × 1329 = 1329
Or... you could just convert 20% into a decimal by carring the . two places to the left
which is 0.2
0.2 × 6645 = 1329
