Answer:

1) The discount is $4.05

The sale price is $18.45

2) The discount is $10

The sale price is $30

3) The discount is $2.6

The sale price is $23.4

Step-by-step explanation:

1) What is the discount and sale price for a haircut that originally cost $22.50 with an 18% discount.

Actual Price= $22.50

Discount = 18%

Finding discount:

$18\%\:of\:22.50\\=\frac{18}{100}\times 22.50\\=4.05$

So, the discount is $4.05

Finding Sale Price

The sale price can be found by: $Sale\;Price=Actual\:Price-Discount$

Putting values and finding sale price:

$Sale\:Price=22.50-4.05\\Sale\:Price=18.45$

The sale price is $18.45

2) What is the discount and sale price for a sweatshirt that originally priced $40.00 with an 25% discount.

Actual Price= $40.00

Discount = 25%

Finding discount:

$25\%\:of\:40.00\\=\frac{25}{100}\times 40.00\\=10$

So, the discount is $10

Finding Sale Price

The sale price can be found by: $Sale\;Price=Actual\:Price-Discount$

Putting values and finding sale price:

$Sale\:Price=40.00-10\\Sale\:Price=30$

The sale price is $30

2) What is the discount and sale price for a large pizza that originally cost $26.00 with an 10% discount.

Actual Price= $26.00

Discount = 10%

Finding discount:

$10\%\:of\:26.00\\=\frac{10}{100}\times 26.00\\=2.6$

So, the discount is $2.6

Finding Sale Price

The sale price can be found by: $Sale\;Price=Actual\:Price-Discount$

Putting values and finding sale price:

$Sale\:Price=26.00-2.6\\Sale\:Price=23.4$

The sale price is $23.4

Which of the following are congruence transformations? A.Shrinking B.Rotating C.Reflecting D.Stretching E.Translating

Soloha48 [4]

Answers:
Rotating
Reflecting
Translating

Explanation:
Congruence transformation is a transformation that does not change neither the side lengths nor the measures of the angles.
This means that the formed image is an exact copy of the original figure

Now, let's check the options:
1- Shrinking: This means that we are decreasing the side lengths.
This option is incorrect

2- Rotating: This means that we are just changing the orientation of the figure without altering any measurements.
This option is correct

3- Reflecting: This means that we are just changing the orientation of the figure without altering any measurements.
This option is correct

4- Stretching: This means that we are increasing the side lengths.
This option is incorrect

5- Translating: This means that we are just changing the position of the figure without altering any measurements.
This option is correct

Hope this helps :)
