Answer:
(a) Describe the rule for translating center Q onto center P.
center P(2, 0)
center Q(0, 4)
you would need to add 2 units in x axis, and subtract 4 units on y axis.
(b) Determine the scale factor for dilating circle Q so that it has the same radius as circle P.
P radius 20, Q radius 2, radiusQ*10 = radiusP, so the scale factor is 10
(c) Are circles P and Q similar? Explain your answer.
they are similar because a similarity transformation (translation, dilation) exists between them
Step-by-step explanation:
Circle Q' is formed by dilating Circle Q by a factor of 10.
What is the scale factor?The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.
To Describe the rule for translating center Q onto center P.
center P(2, 0) and center Q(0, 4)
We would need to add 2 units on x-axis, and subtract 4 units on y-axis.
To find the scale factor for dilating circle Q ,so that it has the same radius as circle P.
P radius 20, Q radius 2, radius Q x 10 = radius P, so the scale factor is 10
It is found that they are similar because a similarity transformation (translation, dilation) exists between them.

B: 3:2
40. If three dice are tossed, find the probability that the sum is less than 16.
Answer:
0.953703703704
Step-by-step explanation:
We have 6 × 6 × 6 = 216 possible results
You can make a table :
obtaining a sum of 18 in only one case : (6 ,6 ,6)
obtaining a sum of 17 in 3 cases : (5 ,6 ,6) ; (6 ,5 ,6) ; (6 ,6 ,5)
obtaining a sum of 16 in 6 cases : (5 ,5 ,6) ; (6 ,5 ,5) ; (5 ,6 ,5)
(4 ,6 ,6) ; (6 ,4 ,6) ; (6 ,6 ,4)
[tex]\text{the probability that the sum is less than 16} =\frac{216-\left( 1+3+6\right) }{216} = \frac{206}{216} =0.953703703704[/tex]

The inside space of two different water tanks are shown below. Which tank has a greater capacity? Justify your response to Question 1.
Answer: C , explanation at the bottom
Step-by-step explanation:
Step 1: Find the volume of tank 1
V= Lwh
l= 6in
w= 1.5in
h= 3in
6x1.5x3= 27
Step 2: Find the volume of tank 2
l= 2 in
w= 1.5 in
h= 9 in
2x1.5x9= 27
Step 3: Compare
27=27
answer= C
Explanation: Since they have the same volume, they can hold the same amounts. Using the formula V=lwh, I multiplied the lengths, widths, and heights of both tanks and then compared their volumes.

Math geometry and measurement
Answer: You will need 1080 in²
Step-by-step explanation:
The formula for finding the area of a triangle is:
Area = 1/2 x b x h
b = base length
h = height
So the equation would be:
1/2 x 12 x 30 = 180
After finding our answer of 180 we multiply it by the amount of pennants we want to hang in this case that number is 6
180 x 6 = 1080
That's how we arrive at our answer of 1080 in².

To understand how to do this problem, we have to look at examples to figure it out. One example would be, if I had a whole cake and cut into 2 pieces I would have two halves, and if I cut it into 4 pieces, I'll have 4 quarters of cake, so 2/2 (two halves) = 4/4 (4 quarters). If I ate 1/2 I would have
(Keep in mind that Equivalent fractions are fractions that are equal to each other)
So to solve these we have to figure out the equal fractions. To do this, we start by multiplying by 2.
(the * symbol is multiplication)
So 3/4 would be 3*2=6 and 4*2=8 so it would be 6/8
Now we can try multiplying it by 3
3*3=9 and 4*3=12 so the 2nd would be 9/12
And we multiply it by 4 now,
3*4=12 and 4*4=16 so the 3th would be 12/16
So, therefore, the answers for 3/4 are 6/8, 9/12, & 12/16.
I'm also going to give you a simplified number that you can use to solve the other problems easier.
3/7 is 3/7. (cannot be simplified)
18/27 is 2/3.
20/80 is 1/4.
You can use these three numbers to start and multiply by 2 and 3 for the other two numbers.
I just gave you a very easy was to solve them and a simple calculator or doing the simple math will be able to help you figure out the rest.
Good luck!

Mathew is a financial analyst for a surf board company. He has found an equation for the revenue of selling t-shirts with the company logo to be r= -3p^2 + 60p +1060, where p is the price of the company’s product. What should he use to determine the price of maximum sales?
Answer: The price of maximum sales is $160
Step-by-step explanation:
This question requires you to find the vertex of this equation. The vertex of a parabola is the point where the parabola crosses its axis of symmetry.
since the coefficient of the [tex]x^2[/tex] term is negative, the vertex will be the highest point on the graph.
this quadratic equation is in standard form: [tex]y = ax^2+bx+c[/tex].
From this, we can derive:
[tex]a = -3[/tex]
[tex]b = 60[/tex]
[tex]c = 1060[/tex]
First, determine the axis of symmetry ([tex]p[/tex] is the variable for the horizontal axis ([tex]x[/tex]) in this instance). This will be our x-coordinate of the vertex.
[tex]p = \frac{-b}{2a}[/tex]
[tex]p = \frac{-(60)}{2(-3)}[/tex]
[tex]p = \frac{-60}{-6}[/tex]
[tex]p=10[/tex]
Then, substitute the axis of symmetry into the function to find the y coordinate of the axis of symmetry. r stands for the variable for the vertical axis in this instance. This will be our y-coordinate of the vertex.
[tex]r = -3(10)^2+60(10)+1060[/tex]
[tex]r = 160[/tex]
As we have determined both the x and y coordinate of the vertex for this equation, we can determine that the maximum point is at [tex](10, 160)[/tex].
the maximum price ([tex]r[/tex]) is 160

Answer: 105 in^2
Step-by-step explanation: The area of the square is 25 because 5x5=25. The area of each triangle is 20, because to find a triangle it is BxH/2. so 5x8/2=20. Multiply this by four because there are four triangles and add the area of the square. So 20x4= 80. 80+25=105

The cost of a cleaning service includes labor and supplies. Supplies are 30% of the total cost. The cost of supplies for a certain cleaning service is $54.
What is the total cost of the cleaning service?
Enter your answer in the box.
Answer:
The total cost of the cleaning service is $180
Step-by-step explanation:
We have, 30% × x = 54
or,
30/100 × x = 54
Multiplying both sides by 100 and dividing both sides by 30,
we have x = 54 × 100/30
x = 180
If you are using a calculator, simply enter 54×100÷30, which will give you the answer.
