When you have two shapes to compare on a coordinate plane, you can determine the scale factor, knowing that the transformation was a dilation. Generate instructions you would give another student to determine the scale factor. If you know the center of dilation is the origin, you can simply divide any non-zero coordinate of the transformed figure by the corresponding coordinate of the original figure to get the scale factor. Sample Response: Locate two corresponding ordered pairs of the two shapes. Calculate how much the pre-image values were multiplied by to obtain the image values. This is your scale factor. You can calculate this by dividing the coordinates of the mage by the corresponding coordinates of the pre-image. Which did you include in your response? Check all that apply. Use corresponding ordered pairs. Divide the coordinates of the image by the pre-image. Determine that the pre-image times the scale factor produces the image.

Answer:
Easiest to pick (0, 0) and (1, 1) probably, then slope is 1.
Step-by-step explanation:
Rise over run for (0, 0) and (1, 1) is rise up 1 and run over 1, so 1/1.
This means slope is 1

A teacher gives a test in which the average of the test scores is 68 and the standard deviation is 14. Realizing that the test was probably too difficult, the teacher decides to scale the tests by adding 10 points to all scores. What is the mean and standard deviation of the scaled test scores?
Answers
Answer:
Mean = 78 ;
Standard deviation = 14
Step-by-step explanation:
Given that:
Mean score = 68
Standard deviation = 14
When a constant value is added to the individual value of a dataset, the new mean value will become the sum of the initial mean value and the constant term added to the values.
Constant Added score = 10
The mean of scaled test score will be:
Mean score + constant added score
68 + 10 = 78
The standard deviation remains unchanged ; Hence, standard deviation = 14

Serena, Alyssa and Katie have just finished lunch at the Rainforest Cafe. Their bill came to $38.96. There is an 8% sales tax. The girls have decided to leave a tip of 15% on the total amount of the bill. How much money did the entire bill come to including the tip?
Answers
Answer:
About $48.39
Step-by-step explanation:
Sales tax only applies to the bill, not the tip.
Calculate the sales tax:
38.96 × 8%
38.96 × 0.08
3.1168
Round to the nearest cent:
3.12
Add the sales tax to the bill:
38.96 + 3.12
42.08
Calculate the tip based "on the total amount of the bill:"
42.08 × 15%
42.08 × 0.15
6.312
Round to the nearest cent:
6.31
Add the tip to the rest of the bill:
42.08 + 6.31
48.39

x1-x2
so
and (x1,y1) and (x2,y2) are those points so plug it in
(1-4)/(-6-4) so that simplifies to -3/-10 so just 3/10 is the slope.

Ms.Lawrence buys 8 ounces of smoked salmon at 17.98 per pound how much money did ms.Lawrence spend on smoked salmon

$8.99
Step-by-step explanation:
1 pound = 16 ounces
y pound = 8 ounces
[tex]\frac{1}{16} :\frac{y}{8}[/tex]
y · 16 = 1 · 8
16y = 8
16y ÷ 16 = 8 ÷ 16
y = 0.5

1 pound = $17.98
0.5 pound = y

In order to find the surface area of a 3-dimensional figure, one must find the 2-dimensional area of all of its faces, then add up the values to find the surface area of the entire figure. The given prism is drawn out in the form of a net, thus, it is rather easy to find the area of each face, and add up the area to find the surface area.
The lateral surface area refers to the surface area of a figure, not including the base of the figure. In this case, the base is the largest rectangle: the one with the dimensions of the following length
[tex](12)*(18)[/tex]
Use the following formulas to find the surface area of each face:
Rectangle: [tex](length)(width)[/tex]
[tex](10)(18)=(180)[/tex]
[tex](10)(18)=(180)[/tex]
Triangle:[tex]\frac{(base)(height)}{2}[/tex]
[tex]\frac{(12)(8)}{2}=48[/tex]
[tex]\frac{(12)(8)}{2}=48[/tex]
Add up all of these values to find the total surface area:
[tex](180)+(180)+(48)+(48)=456[/tex]
