Whenever you want to zoom and enlarge a photo so you can see details, you are using a dilation transformation.
At eye exams, the pupil dilates (widens), allowing in more light and giving your doctor a better view of the back of your eye.
When you build model airplanes, cars, or buildings that are true in scale and measurement, you are performing a dilation.
And even your shadow is a dilation as well.

A football team was given 3 penalties for 15 yards each. What was the total change in their field position from these penalties? Explain your reasoning. *
Answers
Answer:
45
If there was 3 penalties given for 15 yards each then we would have to multiply 3 by 15, or 15 by 3. To get the sum of 45.
Answer: Three 15-yard penalties totals 45 yards lost.
Two 5-yard penalties totals another 10 yards lost.
So the team lost a grand total of 55 yards to penalties.
Step-by-step explanation: 3·15 = 45 now remember 45 then do the equation 2·5 = 10 now 45 + 10 = 55 and there is your answer

EX: You decided to go to college but as a broke college student you couldn't pay for college (because it is expensive) so you decide to take out a student loan. For simplicity's sake let's say that you only need a $15,236.75 loan to add to the money you had saved up for college. However, the loan agency adds a 0.05 per month interest rate as soon as your 4 years of college are over. Knowing that interest adds up fast you decide to try to pay off as much loan debt as you can while still in college with your part-time job. You end up paying off $746.98 leaving you with only $14,489.77 left of the loan. The first month out of college you wind up with only $15,214.26 of college debt. Before the next month however you marry your college sweetheart and as a couple, you take on each other's debts making your grand sum for college debts $32,416.51. After five blissful years of marriage you wind up getting a divorce but because finances have been jumbled (real-world ish) you decide just to divide the $12,758.36 debt from college evenly between the two of you.
Subtraction:
15,236.75-746.98 = 14,489.77Multiplication:
14,489.77x.05 = 15,214.26Addition:
32,416.51 = 15,214.26+17,202.25Division:

A volunteer is buying 10 blankets for the animal shelter. Shipping the blankets costs $1.50 and the volunteer has $75 to spend. What is the maximum amount the volunteer can spend for each blanket? Write an inequality that would represent the situation and solve the inequality. Show your work to justify your answer.
Answers
Answer:
they have $60 dollars because 10 times 1.50 is $15 so they have $60 to spend on blankets
Step-by-step explanation:
The maximum amount spent on each blanket is required.
The maximum amount that can be spent on each blanket is $7.35
Number of blankets is 10.
Let cost of one blanket be [tex]x[/tex]
The cost of shipping 10 blankets is $1.5
Total amount to spent is $150 or less.
The inequality will be
[tex]10x+1.5\leq 150\\\Rightarrow x\leq \dfrac{150-1.5}{10}\\\Rightarrow x\leq 7.35[/tex]
The maximum amount that can be spent on each blanket is $7.35.

Given:
x + (- 8) = 3 x + 6
x- 8 = 3x +6
First,
Add 8 positive unit tiles to both sides
x- 8 + 8 = 3x +6 + 8
