Sienna planned a rectangular pool, as shown in the scale drawing below. 11 in. 7 in. Sienna used the scale drawing above to create a pool that is 14 ft wide x 22 ft long. She then decided to make a pool with a final length of 33 ft. Which expression finds the change in scale factor for the longer pool Sierra is building?

Given that Sienna planned a rectangular pool drawn on a scale 11 inches long by 7 inches wide, and Sienna used the scale drawing above to create a pool that is 14 ft wide x 22 ft long, and she then decided to make a pool with a final length of 33 ft, to determine which expression finds the change in scale factor for the longer pool Sierra is building the following calculation must be performed:
11 inches = 0.916 feet 11 / 0.916 = 12 7 inches = 0.583333 feet 7 / 0.5833333 = 12 Thus, the initial scale is 1:12. 33 / 0.916 = 36
Therefore, the scale factor went from 1:12 to 1:36.

Answer:
y = -1/5x - 10
Step-by-step explanation:
Pick any two points on the line.
(0,-10) and (50,-20)
find the slope by using m = y2-y1/x2 - x1(rise over run)
m = -20-(-10) / 50 - 0
m = -10/50 = -1/5 -- this is your slope
slope intercept form is y = mx + b, but we need to find your b, which is your y intercept. you find this by asking yourself, what is the y coordinate when x = 0? It is -10.
so now you have all the points you need.
y = mx + b
y = -1/5x - 10

Step-by-step explanation:
This diagram shows a pre-image △ABC, and its image, △A′′B′′C′′, after a series of transformations. Select from the drop-down menus to correctly complete the statements. △ABC is Choose... to become △A′B′C′. Then △A′B′C′ is Choose... to become △A′′B′′C′′ . Because the transformations are Choose... , the pre-image and image are Choose... . Triangles on a coordinate plane whose axes are labeled x and y. Triangle A B C has vertex A at 1 comma negative 1, vertex B at 4 comma negative 2, and vertex C at 7 comma 2. Triangle A prime B prime C prime has vertex A prime at negative 1 comma 1, vertex B prime at negative 4 comma 2, and vertex C prime at negative 7 comma negative 2. Triangle A double prime B double prime and C double prime has vertex A double prime at negative 1 comma negative 2, vertex B double prime at negative 4 comma negative 1, and vertex C double prime at negative 7 comma negative 5.
Answers
The answers that complete the statements of the series of transformations are;
- △ABC to △A′B′C′; because the △ABC has been rotated at angle of 180° about the origin.
- △A′B′C′ to △A′′B′′C′′; Because the △A′B′C′ has been shifted down by 3 units.
- All 3 transformations are rigid transformations
- All three transformations are congruent transformations.
The image showing triangles △ABC, △A′′B′′C′′, and △A′B′C′ is missing and so I have attached it.From the image attached, we see the following coordinates of the triangles;
Coordinates of △ABC; A(1, -1), B(4, -2), C(7, 2)
Coordinates of △A′B′C′; A'(-1, 1), B'(-4, 2), C'(-7, -2)
Coordinates of △A′′B′′C′′; A''(-1. -2), B''(-4, -1), C''(-7, -5)
Now, in transformation from △ABC to △A′B′C′, we see that the pattern of transformation is; (x, y) → (−x ,−y). This pattern where coordinates of x and y are transformed to the negative part of them denotes that there has been a rotation at angle of 180° about the origin.In transformation from △A′B′C′ to △A′′B′′C′′, we see that triangle shifted down because the y-coordinates have reduced by 3 units. Thus, we can say that the transformation was to shift △A′B′C′ down by 3 units.In each of the transformations, we can tell that regardless of the position of the triangle, the distances AB, BC and AC remain the same. Thus, the transformation is rigid. The transformations are also congruent because all their corresponding sides are equal.Read more at; https://brainly.com/question/11254677

Does it include all the steps needed to solve the problem? Explain
10.5 x 10.5 = 110.25 PLZ SOLVE THE PROBLEM
110.25 ÷ 1.5 = 73.5
Answers
The steps your teacher gave you are on the right track, but not quite 100% correct.
The first line has us find the area of the entire patio. That area being 110.25 square feet.
The next step is to find the area of each stone. That would be 1.5 x 1.5 = 2.25 square feet.
Therefore, the patio is made up of 110.25 ÷ 2.25 = 49 tiles
When arranged into a square, we'll have a 7 by 7 square set of stone tiles. Notice how 7 x 7 = 49.
