Maria draws △PQR. Then she applies a dilation with scale factor 14 and center of dilation P to the triangle. Next, she translates the image 2 centimeters up and 3 centimeters right. She labels the final image as △XYZ.
Which of the following must be true about △PQR and △XYZ?
△PQR and △XYZ are similar but not congruent.
△PQR and △XYZ are congruent but not similar.
△PQR and △XYZ are neither similar nor congruent.
△PQR and △XYZ are congruent and similar.
Answer:
△PQR and △XYZ are similar but not congruent.
Step-by-step explanation:
When Maria dilated the triangle the size changed and so they can't be congruent. But it wouldn't have changed it's shape, so it'll be similar.
Answer: △PQR and △XYZ are similar but not congruent.

The area of triangle ABD is 50cm, and one of its sides is 10cm in length. Find one of the heights of the triangle.
Answer:
10cm
Step-by-step explanation:
If you want to find one of the heights of the triangle, you need to use some math magic. The magic spell is:
A = (1/2) * b * h
where A is the area, b is the base, and h is the height. Don't ask me why, it just works.
Now, we know that the area of triangle ABD is 50 cm and one of its sides is 10 cm. We can pretend that this side is the base of the triangle. Why? Because it makes our life easier. Trust me.
Then we put these numbers into the magic spell and we get:
50 = (1/2) * 10 * h
Now we need to solve for h, which is the height we want. To do that, we need to do some algebra. Don't worry, it's not that hard. Just follow these steps:
- Multiply both sides by 2. This gives us:
100 = 10 * h
- Divide both sides by 10. This gives us:
10 = h
- Celebrate! We found the height!
So, one of the heights of the triangle is 10 cm. Isn't math fun?
What is the area to this?
Answer:
The Area of the polygon is 36m².
Step-by-step explanation:
Area of the polygon= Area of rectangle + Area of triangle
Diagram
______________
l. l \
3m |. 3m l. \
|. l. /
|_____________ l /
11m. 2m
( 13m).
Area of rectangle= Length × Width
= 11m × 3m
= 33m²
Area of triangle= ½ × base × height
To find the height= 13m - 11m = 2m
= ½ × 3 × 2
= ½ × 6
= 3m²
Area of the polygon= 33m² + 3m² = 36m²

A thunderstorm cloud holds about 6,200,000,000 raindrops. Which of the following shows this number in scientific notation? Answers- F- 0.62*10 to the 10th power G- 6.2*10 to the 9th power H- 6.2*10 to the 8th power J-62.0*10 to the 8th power
Answer:
the answer is G
which is 6.2*10 to the 9th power.
Step-by-step explanation:
In scientific notation you must leave one digit to the place value of ones
so that one digit is 6
So ue come up with 6.2 when ue eliminate all other zeros and end the decimal point between 6 and 2 and that way you have 6.2*10 to the 9th power
Answer:
G, 6.2*10 to the 9th power.

Answer:
-1/2x-2
Step-by-step explanation:
Distribute the negative sign from the right side to make the equation positive
1/4x - 7 + (-1)(3/4x) + (-1)(-5)
(basically multiplying -1 to 3/4x and -5 to eliminate it)
1/4x - 7 + -3/4x+ 5
Make the equation similar
(1/4x + -3/4x) + (-7 + 5)
combine like terms
1/4x + -3/4x = -2/4x --> Simplifies to -1/2x
Do the other integers
-7 + 5 = -2
Put it together
-1/2x-2

Step-by-step explanation:
Samantha earns money when she brings home good grades, but loses money when her grades are poor.
The table below shows how much money Samantha earned and lost last week.
Monday: ($2.25)
Tuesday: (-$1.75)
Wednesday-(-$0.25)
Thursday: ($3.00)
Friday: ($1.75)
If Samantha had $40.75 at the beginning of the week, how much did she have at the end of the week?
PLS SHOW YOUR WORK or i'll just take your answer off
Answer:
$45.75
Step-by-step explanation:
1. Set up the equation: 40.75 + 2.25 - 1.75 - 0.25 + 3 + 1.75 = x
You want to include the amount that she started with which is $40.75 . In this case x is the total amount of money that Samantha has by the end of the week. If Samantha loses money on a certain day you will subtract it, whereas if she gains money you will add it.
2.Simplify: 43 - 1.75 - 0.25 + 3 + 1.75 = x
I just added the 1st two numbers. You can just type this into the calculator if you are comfortable with that or you can solve this by adding and subtracting the numbers on a piece of scratch paper.
3. Simplify: 41.25 - 0.25 + 3 + 1.75 = x
4. Simplify: 41 + 3 + 1.75 = x
5. Simplify: 44 + 1.75 = x
6. Simplify: 45.75 = x

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
Simplify negative 3 over 4 divided by 2 over negative 8.
Answer:
3Step-by-step explanation:
−3/4÷2/−8=?
In the second fraction, move the negative sign from the denominator to the numerator and the value remains the same.
The equivalent equation is
−3/4÷ −2/8=?
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator, leaving the negative sign on the numerator, and changing the operation to multiplication. Then the equation becomes
−3/4× −8/2=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
−3× −8/4×2= 24/8
Since 24 divided by 8 equals 3 then,
24/8 =3
Therefore:
−3/4÷ 2/−8= 3
