Step-by-step explanation:
Reflecting the points across the y axis will be making the x values opposite, so the new points will be:
A(5,5)
B(2,4)
C(4,2)
A reflection across the X axis will be making the Y values opposite so the new points will be:

1 km = 0.62 mi. The distance between Lowell and Shelby is 285
miles. How many kilometers is this?
Round your answer to the nearest whole kilometer.
Answer:
459
Step-by-step explanation:
Since to find out mile to kilometer you divide the mile by 1.609 would equal 458.66304 and rounding it to the nearest whole kilometer is 459 there is you answer.
The distance between Lowell and Shelby is approximately 460 kilometres.
Given that information:
1 km = 0.62 miles
Also given the distance between Lowell and Shelby is 285 miles.
To convert miles to kilometres, use the conversion factor:
1 mile = 1.60934 kilometres
Now calculate the distance in kilometres as follows:
Distance in kilometres = 285 miles × 1.60934 km/mile
Distance in kilometres ≈ 459.7 kilometres.
Now, round the answer to the nearest whole kilometre as follows:
Distance in kilometres ≈ 460 kilometres.
Hence, the distance between Lowell and Shelby is approximately 460 kilometres.

200 random people were surveyed at an amusement park and asked if they ride roller
coasters and if they play games while at the park. 130 of those surveyed ride roller
coasters. 86 of those surveyed play games. 70 of those surveyed ride roller coasters and
play games. Use the formulas in the text to answer the following questions.
a) What is the probability a person at the amusement park rides roller coasters or plays
games?
b) What is the probability a person at the amusement park does ride roller coasters?
c) Are the events of a person riding roller coasters and playing games mutually exclusive?
Answer:
let the P(ride roller coaster) be A and P(play games) be B
a. P(AUB) = P(A) + P(B) - P(AnB)
= 130/200 + 86/200 - 70/20.
= 146/200
= 73/100
b. P(A) = 130/200
= 13/20

The longer leg of a right triangle is 4 inches longer than the shorter leg. The hypotenuse is 8 inches longer than the shorter leg. Find the side lengths of the
triangle.
Answer:
lengths are 12, 16, and 20
Step-by-step explanation:
let 's' = length of smaller leg
let '4+s' = length of second leg
let '8+s' = length of hypotenuse
Now use the Pythagorean Theorem: a² + b² = c²
s² + (4+s)² = (8+s)²
s² + 16 + 8s + s² = 64 + 16s + s²
2s² + 8s + 16 = 64 + 16s + s²
subtract s² from each side:
s² + 8s + 16 = 64 + 16s
subtract '16s' from each side:
s² - 8s + 16 = 64
subtract 64 from each side:
s² -8s - 48 = 0
factor:
(s+4)(s-12) = 0
's equals -4 and 12 but -4 is discarded as a length so smallest side is 12

Corresponding angles converse theorem
Step-by-step explanation:
Angles x and y are corresponding angles.
This makes the lines parallel by the converse of that theorem.
This makes it similar by the corresponding angles converse theorem.
Definition of converse
the reverse of another
The corresponding angles theorem is for the congruency of the angles by parallel lines. Here we want to see if the lines are parallel given the congruency of the angles.
We can flip the operation, checking to see if the angles are congruent, which proves that the lines are parallel.

What single amount on April 1, 2012, is equivalent to a series of equal, semiannual cash flows of $5200 that starts with a cash flow on January 1, 2010, and ends with a cash flow on January 1, 2019? The interest rate is 6% and compounding is quarterly?
The single amount on April 1, 2012 that is equivalent to a series of equal, semiannual cash flows of $5200 is; $57,023.2
Compound Interest FactorWe are given;
Semi annual cash Flow; A_sa = $5200
Interest rate; r = 6%
From April 1, 2012 to January 1 2019 is 6.75 years
Thus; Period; T = 6.75 years
Cash flows is semi annual. Thus; t_a = 1/2
Thus; n_sa = 6.75 * 2
n_sa = 13.5
i_sa = 6% * 1/4 = 1.5%
Thus;
Single amount = 5200 * (P/A, 1.5%, 13.5)
From compound interest tables, P/A at n = 13.5 and at i = 3% by interpolation gives 10.966. Thus;
Single amount = 5200 * 12.137
Single amount = $63,112.4

69
How many bags of potatoes are on the van at the start.
The total number of bags the van have at the starting is 70.
What is ratio?Ratio is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another.
According to the given question.
The sacks of potatoes delivered in two different shops are in the ratio 3:7.
Also, one shop has 28 more bags than the other.
Let the number of bags of potatoes at one shop be x.
Then, the bags of potatoes in another shop = x + 28
Therefore,
[tex]\frac{x}{28 + x } =\frac{3}{7}[/tex]
⇒ [tex]7x = 3(28 + x)[/tex]
⇒ [tex]7x = 84 + 3x[/tex]
⇒ [tex]4x = 84[/tex]
⇒[tex]x = 21[/tex]
So, the total number of bags
[tex]=x + (x + 28)[/tex]
[tex]=2x + 28[/tex]
[tex]= 2(21) + 28[/tex]
[tex]= 42 + 28[/tex]
[tex]= 70[/tex]
Hence, the total number of bags the van have at the starting is 70.

Explain why a change from 20 to 40 is a 100% increase, but a change from 40 to 20 is a 50% decrease. I don't under stand it
Answer:
Step-by-step explanation:
40 to 20 is a 50% decrease because you are halving it
20 to 40 is a 100% increase because you are adding 100% of 20 to 20 and you get 40.
Answer:
I hope this helps :)
Step-by-step explanation:
For 20 to 40, how much are you adding to your first number (20) to get your second number (40)?
You are adding 20 to your original number, which is the same amountSince you add the same amount to your original number (100% of your original number,) it is a 100% increase.For example: a 50% increase from 20 would be adding 50% of your original number (20) to the original number (e.g. 20 + (20/2) = 30 --> 50% increase)For 40 to 20, how much are you decreasing from your first number (40) to get your second number (20)?
You are subtracting 20 from your original number, which is half of the amountSince you subtract half (50%) of your original number, it is a 50% decreaseFor example: a 50% decrease from 30 would be taking away 50% of your original number (30) (e.g. 30 - (30/2) = 15 --> 50% decrease)
