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:
2 [tex]\frac{3}{8}[/tex]
Step-by-step explanation:
3/4 + 5/6 (lowest common denominator = 12)
= 9/12 + 10/12
= 19/12
19/12 ÷ 2/3 (reciprocate 2/3 to replace division sign by multiplication sign)

-3x + b = 6x
solve for x
Answer:
x = 1/9(b)
Step-by-step explanation:
Step 1: Subtract 6x from both sides.
[tex]-3x + b - 6x = 6x - 6x[/tex] [tex]-9x + b = 0[/tex]Step 2: Subtract b from both sides.
[tex]-9x + b - b = 0 - b[/tex] [tex]-9x = -b[/tex]Step 3: Divide both sides by -9.
[tex]\frac{-9x}{-9}= \frac{-b}{-9}[/tex] [tex]x = \frac{1}{9}b[/tex]Therefore, [tex]x = \frac{1}{9}b[/tex].

2x+65=4x−3
Answer:
x=7/6
Step-by-step explanation:
subtract the 4x from both sides of the equation
(2x+6)-4x=4x-3-4x
find common denominator
(2x+6)/5+(5(-4)x)/5=4x-3-4x
then combine fractions
(2x+6+5(-4)x)/5=4x-3-4x
then multiply the 5&4
(2x+6-20x)/5= 4x3-4x
combine terms
(-18x+6)/5= -3
then multiply everything by 5
-18x+6= -15
subtract the 6 from both sides
-18x= -21
divide -21 by -18
(-21)/(-18)=x

Step-by-step explanation:
Step 1: Distribute.

Answer:
Question : The dress store is having a sale where all merchandise is 1/4 off. A woman buys $48 of merchandise at the sale price
Answer :
There are two ways to look at this. If we take 1/4 off, then the $48 is 3/4 of the original price.
(3/4)p = 48
(4/3)(3/4)p = 48(4/3)
p = 64
Regular price is $64.

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.
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

Jen ran directly toward school at a constant velocity for 36 seconds. In one-third of that time, she ran 120 meters. What was her velocity?
Answer is 10 m/s
Step-by-step explanation:-First, we need to calculate one-third of 36 seconds :
[tex] \frac{1}{3} \times 36[/tex]
[tex] \frac{36}{3} [/tex]
[tex]12[/tex]
Now, to find velocity, let's divide the distance by time :
[tex]velocity = \frac{distance}{time} [/tex]
[tex]velocity = \frac{120}{12} [/tex]
[tex]velocity = 10 \: m/s[/tex]
Therefore, Jen's velocity is 10 m/s .

An ostrich was 960meters east of its nest. It ran west at a constant velocity for 160seconds. In that time, it ran halfway to its nest. What was its velocity?
Answer is 3 m/s.
Step-by-step explanation:-The ostrich ran at a constant velocity, so it's velocity was :
[tex]velocity = \frac{distance}{time} [/tex]
It is said that the bird ran for 160 seconds and it made it half-way to its nest, so the distance was :
[tex]distance = \frac{960 \: metres}{time} [/tex]
[tex]distance = 480 \: metres[/tex]
And the velocity is :-
[tex]velocity = \frac{480 \: metres}{160 \: seconds} [/tex]
[tex]velocity = 3 \: m/s[/tex]
Therefore, the ostrich ran at a velocity of 3 m/s .
