Answer:
The scale factor of the dilation is 6.
Step-by-step explanation:
Dilation of a Triangle
A dilation is a transformation that produces an image that is the same shape as the original but at a different size.
Dilating a point centered at the origin means multiplying its coordinates by a fixed scale factor k.
If point A(3,6) is dilated centered at the origin by a scale factor of 4, then its new coordinates are A'(12,24).
Triangle FGH has vertices F(−5, 0), G(0, 5), and H(5, 0).
It's known a dilation, centered at the origin, is applied to this triangle and the image has vertices F′(−30, 0), G′(0, 30), and H′(30, 0)
Comparing the coordinates F and F', the x-coordinate is scaled by a factor of (-30)/(-5)=6
Comparing the coordinates G and G', the y-coordinate is scaled by a factor of (30)/(5)=6
Comparing the coordinates H and H', the x-coordinate is scaled by a factor of (30)/(5)=6
Since all the scale factors are the same, we can conclude the scale factor of the dilation is 6.

The regular price of a swimsuit in the junior department of a store is $54. The store advertises an end-of-season sale at 40% off the regular price of all swimsuits. Two weeks later the store advertises a bonus sale at an additional 1/5 off the end-of-season sale price of all swimsuits. Shannon and Mary decide this is a great time to shop for swimsuits. Shannon figures that the swimsuits are now 60% off the regular price. Mary disagrees, because she figures that the total discount is actually less than 60%.
a. What is the cost of a swimsuit during the end-of-season sale? Justify your reasoning using a model.
b. What is the cost of a swimsuit during the additional 1/5-off bonus sale? How can you show this with a model?
c. Did Shannon or Mary figure the discount correctly? Use a model to explain.
answer for a b and c plzzz
Answer:
the cost of a swimsuit during the end-of-season sale is 21.6 because 40% of 54
b. 21.4
40% of 54 +(-1/5)
c. No because the 60% of 54 is 32.4

Given:15y+7=12-20y prove:y=1/7 (I just need the prove thanks)
Answer:
15y+7=12-20y (add 20y to both sides)
35y+7=12 (minus 7 from both sides)
35y = 5 (divide both sides by 35) (5/35=1/7)
y= 1/7
Answer:
64/7 = 64/7 yes y = 1/7
Step-by-step explanation:
To prove this we simply have to plug in!
15(1/7) + 7 = 12 - 20(1/7) (simplify)
15/7 + 7 = 12 - 20/7 (simplify further)
64/7 = 64/7
So yes y = 1/7

Lin has a pet German shepherd that weighs 38 when measured in one unit and 84 when measured in a different unit. which measurement is in pounds, and which is in kilograms?
Given :
Lin has a pet German shepherd that weighs 38 when measured in one unit and 84 when measured in a different unit.
To Find :
Which measurement is in pounds, and which is in kilograms.
Solution :
We know, mass in kg and pounds are related as :
[tex]m_P = 2.2m_{kg}[/tex]
Putting, [tex]m_{kg}=38[/tex] and [tex]m_P=84[/tex] , we get :
LHS = 84
RHS = 2.2 × 38 = 83.6 ≈ 84
Since, LHS = RHS .
Therefore, 38 units is Kg and 84 units in Pounds.
Hence, this is the required solution.

kayla is tracking the progress of her plants growth. today the plant is 8 cm high. the plant grows 2 cm per day.
a. write a linear model that represents the height of the plant after d days
b. when will the plant be at a height of 20 cm?
Answer:
30 cm
Step-by-step explanation:
A. Multiply daily rate by number of days and add that to the starting height:
Height = 2d + 8
B. Set height to 20 and solve for d:
20 = 2d +8
Subtract 8 from both sides
12 = 2d
Divide both sides by 2
D = 6

Martha wants to go to band camp this summer that costs $103.50 she has $10 and plans to save $5.50 each week. How many weeks will it take her to save the money? In algebra pls
Answer:
19 weeks
Step-by-step explanation:
You'll be looking for an equation the form of
y=mx+b
Given:
b = $103.50
m = $5.50
x = ? (where x is in weeks)
Next, set y = 0
--> mx+b = 0
Rearrange
x = (-b/m)
Plug in b and m:
x = (-(-103.5)/5.5) = 18.818
Rounding up, it will Martha 19 weeks to save enough money.
Paul Smith pays $50.00 a month for group health insurance. There is a $300 deductible. His medical bills for the last year were $2,600.00. Paul’s insurance company provided payment of 80% of the bills less the deductible. What was Paul’s total cost (including the monthly premium)?
Answer:
$1,360
Step-by-step explanation:
Take the monthly payment of $50 and multiply it by 12 because there is 12 months in a year which is $600. Next subtract $2,600 by your deduction of $300 which is $2,300. Then multiply by 20% because the insurance pays 80% leaving you with 20%, you get $460. Add $460 and $300 because those are the amounts you paid and you get $760. Now add the $600 to the $760 because of the monthly payment. The total comes out to $1,360.
