Explain how to show a reflected object is congruent to its preimage. Be specific.
Answer:
To show that a reflected object is congruent to its preimage, follow these steps:
Identify the line of reflection.
Locate corresponding points on the preimage and its reflection.
Measure the distances between the line of reflection and the corresponding points.
Compare the distances for each corresponding point.
If the distances are equal, the reflected object is congruent to the preimage.
Step-by-step explanation:
Step-by-step explanation:
To show that a reflected object is congruent to its preimage, you need to demonstrate that the reflected object and the preimage have the same size and shape. Here's how you can do it:

You bought some jeans for $55. Today they were on sale for $49.50. What was the percent decrease in price?
10% decrease
Explain how you these answers are right
Answer:
Step-by-step explanation:
Profit % = \(\frac{New Value - Old Value}{Old value}\)x 100
Loss % = \(\frac{Old Value-NewValue}{Old Value}\)
Profit % = \(\frac{16.1-5}{5}\) × 100
= \(\frac{11.1}{5}\) x 100
= 11.1 x 20
= 222% increase
∴ Hence, proved that the answer is correct.
Profit % = \(\frac{57.6-40}{40}\)×100
= 44% increase
∴ Hence, proved that the answer is correct.
Profit % = \(\frac{63.6-60}{60}\)x 100
= 6% increase
∴ Hence, proved that the answer is correct.
Loss % = \(\frac{110-13.2}{110}\)x 100
= 88% decrease
∴ Hence, proved that the answer is correct.
Loss % = \(\frac{55-49.5}{55}\)x 100
= 10% decrease
∴ Hence, proved that the answer is correct.

Answer:
Step-by-step explanation:
Old Value: 5
New Value: 16.1
16.1-5=11.1
11.1 divided by 5= 2.22
2.22/1 x 100=222%
222% increase
Old Value: 40
New Value: 57.6
57.6-40=17.6
17.6 divided by 40= 0.44
0.44/1 x 100= 44%
44% increase
Old Value: 60
New Value: 63.6
63.6-60=3.6
3.6 divided by 60= 0.06
0.06/1 x 100= 6%
6% increase
Old Value: 110
New Value: 13.2
13.2-110= -96.8
-96.8 divided by 110= -0.88
-0.88/1 x 100= 88%
88% decrease

A) This is a translation because triangle ABC has slid down.
B) This is a translation because triangle ABC has slid up.
C) This is a reflection because triangle ABC has been flipped over the y-axis.
D) This is a reflection because triangle ABC has been flipped over the x-axis.
Answer:
D) This is a reflection because triangle ABC has been flipped over the x-axis.
Step-by-step explanation:
You can see that A'B'C' is congruent to ABC
You can also confirm the fact that it is a reflection by counting the distance from a point to the X axis and comparing it to the corresponding point- for example, A is 2 units above the X axis, and A' is 2 units below.

Step-by-step explanation:
13oz bottle of dish soap sells for 2.34
Answer: hope this helps ♡
The unit price of the 13 oz bottle is $0.18 per oz
The unit price of the 30 oz bottle is $0.53 per oz
The 13 oz bottle for $2.34 is a better deal.
Step-by-step explanation:
Unitary method: diving the number that you want to find out over the already known number. (just try to understand this lol) :)
13 oz = $2.34
13 oz bottle is $? per oz
\(\frac{2.34}{13}\) = 0.18
1 oz = $0.18
(double check: 0.18×13=2.34)
30 oz = $15.90
30 oz bottle is $? per oz
\(\frac{15.9}{30}\) = 0.53
1 oz = $0.53
(double check: 0.53×30=15.9)
The 13 oz bottle for $2.34 is a better deal.
A single, standard cube is tossed. What is the probability of getting a number greater than 3?
Answer:
1/2 or 50%
Step-by-step explanation:
numbers on a dice:
1, 2, 3, 4, 5, 6
4 5 and 6 are above 3
therefore, there are 3 numbers that are greater than 3 on a standard dice
3/6 can be simplified to 1/2 which is also the same as 50%.

Answer:
I don't think anyone is going to answer ALL of those questions but ill get you started...
Step-by-step explanation:
1: 7.8 billion. Used billions as my unit. Did not use a site, I already knew this information.
2: The population has increased by approximately 12% in the last 10 years. Worldometer.com shows this information.
3: 1950 population: 2.5 billion, 1960 population: 3.039 billion. The population comparison can be achieved by looking at the increase in billions. The increase was almost 0.6 billion.
Hopefully, that can get you started.
