Answer:
x =3.9
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2 + b^2 =c^2
x^2 + (5x)^2 = 20 ^2
x^2 + 25x^2 = 400
Combine like terms
26 x^2 = 400
Divide each side by 26
x^2 = 400/26
Take the square root of each side
sqrt(x^2) = sqrt(400/26)
x = sqrt(400/26)
x =3.922322703
Rounding to the nearest tenth
x =3.9

I need help arranging cards in a 4 x 4 grid with numbers 1-9 so that the sum of each row and each column is 20. This what the grid looks like:
Answers
Answer:
8, 2, 8, 2
7, 3, 7, 3
6, 4 6, 4
9, 1, 9, 1
Step-by-step explanation:
In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.
So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.
Since there are 18 numbers, I'm assuming we don't have to use all of them.

In the case of this distance, trying to imagine 5 x 10^6 is obviously way too ridiculous
The answer is B.
5 kilometers is a reasonable way to describe the distance.
Describing that distance in such tiny units (such as millimeters) is ridiculous. Yes, 5 Km is the same as 5,000,000 mm, but I can't picture what 5,000,000 of anything really looks like.
And we do use scientific notation for distances. The distance from Earth to the Sun is about 149,597,870 kilometers. Most people would state that as 1.5x10^8 Km, using scientific notation.

Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

What are the coordinates of vertex A?
Enter your answers in the boxes.
Answers
Answer:
A (3, 4)
Step-by-step explanation:
A has to be positioned horizontally along B. This means its x coordinate is the same as x-coordinate of B which is 4
A also has to be positioned vertically below C. This means its y coordinate is the same as the y-coordinate of C. So y-coordinate of A is 3
So coordinates of A are (3, 4)

Enter the correct answer in the box.
Answers
Answer:$256.10
Step-by-step explanation:
x * 1.2= 307.32
X= 307.32/1.2
X= 256.1
The original price is $245.86.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Total price: n = $307.32
Tax or tip rate: 20%
Let m be the original price.
So,
Tax = Original Price x Tax %/100
Tax = 307.32 × 20/100
Tax = 307.32 x 0.2
Tax = $61.46
Original Price = Original Price - Tax
Original Price = 307.32 - 61.464
Original Price = $245.86
Therefore, $245.86 is the price.

If the relationships below are given in the form (input, output), which pairing always describes a function? (a person’s age in years, that same person’s height in inches) (a person’s weight in pounds, that same person’s height in inches) (a person’s height in centimeters, that same person’s height in inches) (a person’s telephone number, that same person’s height in inches)
Answers
Answer:
A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:
(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.
(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.
(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.
(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.
So, the pairings that always describe a function are:
(a person’s age in years, that same person’s height in inches)
(a person’s weight in pounds, that same person’s height in inches)
(a person’s height in centimeters, that same person’s height in inches)
These three pairings meet the criteria of a function, where each input corresponds to a unique output.
The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)
How did we arrive at this assertion?A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:
1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).
2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.
3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.
4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).
So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Which congruence transformation follow the rule (x,y) ---> (x, -y)?
Answers
Answer.
The answer is A or D. ( Based on what the original color is)
Step-by-step explanation:
I say A because if the original color is blue, then the second shape would cross over the -y axis.
If it is red, then D is correct because the second color crosses over the -y axis.
Answer:
C
Step-by-step explanation:
(x, y) --> (x, -y) ==> also known as a reflection over the x-axis.
All x values stay the same, while the y values becomes negative.If the x values are negative, they stay the same. If the y values are already negative, they stay the same.With this knowledge, our finally answer will be C.
A (0, 5) --> A' (0, -5)
B (2, 3) --> B' (2, -3)
C (0, 2) --> C' (0, -2)
D (-3, 4) --> D' (-3, -4)
