Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P′Q′R′ has vertices P′(4, 0), Q′(3, 1), and R′(−1, −2).
Plot triangles PQR and P′Q′R′ on your own coordinate grid.
Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P′Q′R′? Explain your answer. (4 points)
Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)
Part C: Are the two triangles PQR and P′'Q′'R′' congruent? Explain your answer. (2 points)
Answer:
The scale factor from triangle PQR to P'Q'R' is 1/4.
The length of each side of the triangle is divided by 4, in other words it is multiplied by the scale factor of 4.
If P'Q'R" is reflected over the y-axis the new points would be: (1, 0) (0, 1) and (-2, 1).
No, the triangles are not congruent. There was a dilation of 1/4 in the triangles.

An octagon has an area of 55.3 square inches. It is a smaller version of an octagon whose dimensions are 7 times larger. What is the area of the larger octagon?
9514 1404 393
Answer:
2709.7 square inches
Step-by-step explanation:
If the linear dimensions are a factor of 7 larger, then the area is a factor of 7^2 = 49 larger.
larger area = 49(55.3 in^2) = 2709.7 in^2

The product of 45 and the counting number n is a perfect cube. find the least possible value for n.
PLS HELP.
The counting number n is 75 which when multiplied with 45 gives perfect cube.
What is a perfect cube?Numbers which are the triple product of the exact number are known as perfect cubes.
In other words, we can say the value produced by multiplying a whole number by three times itself is a perfect cube.
A number that may be expressed as three times the product of another integer is also termed as a perfect cube.
It is given in the question that the product of 45 and the counting number n is a perfect cube
So, we have to find the counting number n
First of all we will factorise 45
45 = 5 × 9
After factorising we get,
45 = 3×3×5
For 45 to become perfect cube we have to multiply the factors with 3×5²
45 = 3×3×3×5×5×5
∴ 3×5² = 75
Hence , the counting number n is 75 which when multiplied with 45 gives perfect cube.

Which of the following sets shows all the numbers from the set {0, 0.5, 1, 2.5, 3} that make the inequality 2a + 3 ≥ 8 true?
{2.5, 3}
{1, 2.5, 3}
{0, 0.5, 1}
{0.5, 1}
Answer:
A
Step-by-step explanation:
it can't be any answer with 0, because when you substititue the variable a with 0, it simplifies to 3 ≥ 8 which is false, so C and D are incorrect. it also can't be B since when you substitue a with 1 it simplifies to 6 ≥ 8 which is also false. therefore A is the correct answer, hope this helps :)
Answer:
{2.5, 3}
Step-by-step explanation:
2a + 3 ≥ 8
2a + 3 - 3 ≥ 8 - 3
2a ≥ 5
[tex]\frac{2a}{2}[/tex] ≥ [tex]\frac{5}{2}[/tex]
a ≥ 2.5
From the expression above, a is equal to 2.5 and any number above 2.5
∴The answer is {2.5, 3}

Lee spins the spinner once. Which outcome is most likely?
A.
The arrow lands on a number less than 6.
B.
The arrow lands on 1 or 2.
C.
The arrow lands on an odd number.
D.
The arrow lands on a number divisible by 3.
Answer: A

A baseball coach order hats for his team. Each hat cost $10. The shipping charger is $6. The total cost of the order must be less than $125. Which inequality can be used to solve?
Answer:
10x + 6 < 125
Step-by-step explanation:
Hi,
10x is the cost per hat. 6 is the charging fee. 125 is the total cost of the order. We put x because we don't know how many hats they're going to buy. 6 is the amount they pay no matter what. And < is used because the total cost has to be less than 125, not less than or equal to, but LESS than.
