The independent variable: lengths of the sides
The dependent variable: the perimeter of a square,
K(5) = 20.
What is the Dependent and Independent variable of a Function?The dependent variable of a function is the output of a function that changes as a result of any change in the independent variable, which is the input of the function.
The input (independent variable) determines the output (dependent variable) of a function.
Therefore, we can make the following deductions:
The independent variable, x, represents lengths of the sides, and the dependent variable is the perimeter of a square, because the perimeter of the square depends on the length of the side of the square.
The function that relates to the variables is: K(x) = 4x
So, K(5) = 4(5) = 20.
This means, if 5 is the length of one of the sides of the square, then 20 is the perimeter of the square.

Allison is saving money to buy a video game system. in the first week her savings were $8 less than 2/5 the price of the system. in the second week, she saved 50 cents more than 1/2 the price of the system. she was still $37 short. find the price of the system.
Answers
Hence , the price of the system $295 .
The linear equations in one variable is associate degree equation that is expressed within the sort of ax+b = zero, wherever a and b square measure 2 integers, and x may be a variable and has just one resolution. as an example, 2x+3=8 may be a equation having one variable in it.Let the price of the system be "x" .
It is given that in the first week her savings were $8 less than 2/5 the price of the system which can be represented by equation
First week savings = (2/5)x -8
It is also given that in the second week, she saved 50 cents more than 1/2 the price of the system which can be represented by equation
Second week savings = (1/2)x +0.5
savings + short = price of system
(2/5)x -8 + (1/2)x +0.5 + 37 = x
(2/5)x + (1/2)x + 29.5 = x
4x + 5x/ 10 + 29.5 = x
9x/10+ 29.5 = x

Answers
With the help of Pythagoras Theorem for triangles, we get that the possible areas of the square are: 12 sq. units and 20 sq. units, according to the cases mentioned.
What is Pythagoras Theorem?According to the Pythagoras Theorem, in a right angled triangle, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Given:
Sides of a right triangle are 2 and 4 units.
To find: Area of a square that shares a side with the third side of the triangle.
Finding:
There can the following cases:
If 2 and 4 units are the lengths of the perpendicular sides.
Then, by Pythagoras Theorem, -
[tex]H^{2} = 2^{2}+4^{2}\\ H^{2} = Side^{2}\\H=Side \\H= \sqrt{4+16} \\H= \sqrt{20} \\H= 2\sqrt{5}[/tex]
Hence, the area of the square = side² = 20 units²
If 4 units is the length of hypotenuse.
Then, by Pythagoras Theorem,
[tex]4^{2} = 2^{2} + A^{2} \\16 - 4 = A^{2} \\= \sqrt{12}\\[/tex]
side of triangle = [tex]\sqrt{12}[/tex]

The average of five numbers is 72, two of them are 70 and 74. Find the average of the other three numbers.
Answers
The average of the other 3 numbers is 72.
Average or mean is a measure of central tendency which calculates the central point of a data-set.
Average of a set of numbers is calculated by taking the sum of the numbers and dividing it by the total frequency of the numbers.
If 3 numbers a , b and c are taken then the average is equal to
(a+b+c) ÷3
Given average of 5 numbers is 72.
Therefore the sum of the numbers is 72 × 5 = 360
Two of the numbers are 70 and 74 .
Sum of the remaining 3 numbers = 360 - (70 + 74) = 360 - 144 = 216
Average of the 3 numbers = 216 ÷ 3 = 72
Therefore the average of the remaining 3 numbers is 72.

find the rise and the run

Answer:

Step-by-step explanation:
The picture is a little blurry so the graph is hard to read. But I believe the answer is 7/8. The rose would be counting up or down the y axis and the run is counting forward or backward on the x axis.
Hope this helps! :)
Answer:
rise = 7, run = 8
slope = rise/run = 7/8
See attached picture for graph in case you have to plot
Step-by-step explanation:
Take two distinguishable points, (x1, y1) and (x2, y2) on the graph. Find the difference in their y values= y2 - y1. This will be the rise
Find the corresponding difference in the x values, x2 - x1. This will be the run
Divide the y difference by the x difference and you get rise/run which is the slope of the line
Two clear points are (x1 = 0, y1= -7) and (x2=8, y2=0)
(y2 - y1)/(x2 - x1)
= (0 - (-7)/(8 - 0))
= (0+7/(8 - 0) ==> 2 negatives make a positive
= 7/8 and that is rise/run
Rise = 7, run = 8

We also need to find the difference between the numbers.
The number 3 is in the 3rd place (hundreds) of the number 5,341 as a digit will be replaced by 8 to form the number 5,841.
This means that 300 is replaced by 800 because the third place in both the numbers is of hundreds.
The difference between 800 and 300 is:
