Quadrilateral P'Q'R'S' is a dilation of the quadrilateral PQRS, with the origin as the center of dilation.
What is the rule used to create this dilation?
Answers
step by step solution: life
The dilation scale factor of the quadrilateral is k = 1/2
What is Dilation?Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent
The result of dilation is that the shapes and boundaries of objects in the input image are expanded or thickened. It is often used in conjunction with other morphological operations such as erosion, opening, and closing to manipulate and enhance images.
Given data ,
Let the scale factor of the dilation be represented as k
Now , the coordinates of the quadrilateral PQRS is
P ( -2 , 5 )
Now , the coordinates of the quadrilateral P'Q'R'S' is
P' ( -1 , 2.5 )
So , the dilation factor k is given by
k = -1 / -2
k = 1/2
Hence , the dilation is k = 1/2

The measures of the angles of a triangle are shown in the figure below. Find the measure of the smallest angle.
(2x+18)°
55°
(4x+11)°
Answers
Answer:
(2x+18) degrees
Step-by-step explanation:
A triangle is a total of 180 degrees, so you would do:
(2x+18)+55+(4x+11)=180
(2x+4x)+(18+55+11)=180 <- take out parentheses and add like terms
6x+84=180 <- subtract 84 from both sides of the equation
6x=96 <- divide 6 from each side
x=16
Now that you know what x is you would plug it into each of the angles
Angle 1: 2x+18 --> 2(16)+18= 32+18= 50
Angle 2: 55
Angle 3: 4x+11 --> 4(16)+18= 64+18= 82
Then out of these three angles of the triangle, angle 1 (2x+18) would be the smallest.

5. 5/12 of a pound
Step-by-step explanation:
3. "at least 3/8" means to include that column in the count.
4. 3(1/4) + 4(3/8 ) + 3(1/2) + 2(5/8)
= 3/4 + 12/8 + 3/2 + 10/8 but we need a common denominator. LMK in the comments if you need help with that
= 6/8 + 12/8 + 12/8 + 10/8
= 40/8
= 5 pounds.
5. For the average, we add up all the weights, then divide by the number of kittens. Thankfully, we just added everything up in #4. Since we're going to be dividing 5 by 12, we'll end up with a decimal. But since the whole problem was written in fractions, we'll keep it in fractions.
40/8 divided by 12 kittens
40/8 divided by 12 = 40/8 muliplied by the inverse of 12 which is 1/12
40/8 x 1/12
= 40/96
Our numerator and denominator can be evenly dived by 8, so the fraction is reduced to
= 5/12

* ♡ The Answer ♡
・x = -5
*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*
♡ The Explanation/Step-By-Step ♡
・3 (x + 4) = x - 8 - 2x
3 (x + 4) = x - 2x - 8
3 (x + 4) = -x - 8
3 (x + 4): 3x + 12
Apply the distributive law! : a(b + c) = ab + ac
a = 3, b = x, c = 4
= 3x + 3 x 4
Multiply: 3 x 4 = 12
= 3x + 12
3x + 12 = -x - 8
Subtract 12 from both sides!
3x + 12 - 12 = -x - 8 - 12
Simplify!
3x = -x - 20
Add x to both sides!
3x + x = -x - 20 + x
Simplify!
4x/4 = -20/4
Simplify 4x/4 : x
Divide the numbers!
4/4 = 1 = x
Simplify!
-20/4 : -5
-20/4
Apply the fraction rule! : -a/b = -a/b
= -20/4
Divide the numbers!
20/4 = 5
= -5
x = -5

You are comparing the costs of a certain model of ladder at a hardware store and online. The sale information can be found below.
PART A: Calculate the final cost of the ladder at each of the stores. Include the proportion(s) or equations(s) you needed to reach your answer.
PART B: Suppose the hardware store decides to offer 10% off the cost of the ladder (but still keep the 6% tax) and the online store decides to offer free shipping and handling (but still keep the 6% tax). In this situation, which store offers the better final cost? Include the proportion(s) or equations(s) you needed to reach your answer.
Answers
Answer:
Part A:
Hardware Store = $371Online Store = $355.20Part B: The hardware store is cheaper.
Step-by-step explanation:
Part A:
At the hardware store, the ladder is 350 plus 6% tax. To solve this you would multiply 350 by 1.06 tax. Then you would get 371. Online, the ladder is 320 plus 6% tax and 5% shipping. To solve this you would multiply 320 by 1.11 (tax and shipping combined). Then you would get 355.20.
Part B:
To solve the cost of the ladder at the hardware store, you would need to first multiply 350 by 0.9 for the 10% discount. That would get you 315. Then add the 6% tax to get 333.90. To solve for the online ladder, you would need to multiply 320 by 1.06 (6%), and get an answer of 339.20. This means that the hardware store is cheaper.
Answer
Step-by-step explanation: How to find the percentage from the total value?
Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
We need to Write the percent as a fraction in simplest form
16.24%
So, we can rewrite it as;
16.24 / 100
16 and 24/100 or 16 6/25
So the percent as a fraction is 16 6/25
We are given that;
Cost of ladder= $320
Sales tax of shipping and handling is 5% and 6%
Off on hardware= 10%
Now,
PART A:
At the online store, the ladder costs $320, and the sales tax is 6% of $320, which is:
$320 x 0.06 = $19.20
The shipping and handling is 5% of $320, which is:
$320 x 0.05 = $16
So the total cost of buying the ladder online is:
$320 + $19.20 + $16 = $355.20
At the physical store, the ladder costs $350, and the sales tax is 6% of $350, which is:
$350 x 0.06 = $21
So the total cost of buying the ladder at the physical store is:
$350 + $21 = $371
Therefore, buying the ladder online would be cheaper, with a total cost of $355.20.
PART B:
If the hardware store is offering 10% off the price of the ladder, the cost of the ladder would be:
$350 x 0.1 = $35 off
$350 - $35 = $315
So the total cost of buying the ladder at the physical store with the discount would be:
$315 + $18.90 (6% sales tax) = $333.90
If the online store is offering free shipping and handling, the total cost of buying the ladder online would be the same as the cost of the ladder:
$320 + $19.20 (6% sales tax) = $339.20
