The equations is the variable isolated
What is Variable?A variable is an alphabet or phrase that stands in for an unknowable quantity, value, or number. Particularly in the case of algebraic expressions or algebra, the variables are utilised.
Given:
We know when we find the value of variable we need to isolate the variable.
We have given some equations, the isolated variable means only the variable on one side of the equal.
So, among the Equation only x = 9/2 + 4 has isolated variable x.
The other parts have some number or other quantities along with variable.

Find the selling price.
A store pays $8 for a pool noodle. The markup is 20%.
The selling price is $
Answer:
The selling price is $9.60.
Answer:
the selling price of the pool noodle is $9.60.
Step-by-step explanation:
The selling price of the pool noodle can be calculated by adding the markup to the cost price.
Step 1: Calculate the markup amount. The markup is 20% of the cost price of $8, which is calculated as: 20/100 * $8 = $1.60.
Step 2: Add the markup amount to the cost price to find the selling price. The selling price is $8 + $1.60 = $9.60.

Consider the equation y=3x-1. Identify the slope and y-intercept and sketch the graph if you can.
Answer:
Slope: 3, Y-intercept: -1
Step-by-step explanation:
Remember, the slope is always the number before x in this kind of form. The Y-intercept is when x is 0, so when x = 0, y = -1, and that is the Y-intercept

The area of a rectangle whose perimeter is a fixed 80 feet is given by A=40w - w2 , where w is the width of the rectangle. Determine the width of the rectangle that gives the maximum area. What type of special rectangle is necessary to produce this maximum area? Justify.
Answer:
Width=20 feet
Since Length=Width=20 feet, the rectangle is a Square.
Step-by-step explanation:
Area, [tex]A=40w - w^2[/tex]
To determine the width of the rectangle that gives the maximum area, we take the derivative of A and solve for its critical point.
[tex]A'=40 - 2w\\$When A'=0\\40-2w=0\\40=2w\\w=20 feet[/tex]
The width of the rectangle that gives the maximum area =20 feet.
Perimeter of a rectangle=2(l+w)
Perimeter of the rectangle=80 feet
2(l+w)=80
2l+2(20)=80
2l=80-40
2l=40
l=20 feet
Since the length and width are equal, the special type of rectangle that produces this maximum area is a Square.
The area of the rectangle is the product of its dimensions
The width that gives the maximum area is 20 feetThe special rectangle is a squareThe area of the rectangle is given as:
[tex]\mathbf{A = 40w - w^2}[/tex]
Differentiate
[tex]\mathbf{A' = 40 - 2w}[/tex]
Set to 0
[tex]\mathbf{40 - 2w = 0}[/tex]
Add 2w to both sides
[tex]\mathbf{ 2w = 40}[/tex]
Divide both sides by 2
[tex]\mathbf{ w = 20}[/tex]
This means that, the width that gives the maximum area is 20 feet
The perimeter of a rectangle is:
[tex]\mathbf{P = 2(l + w)}[/tex]
So, we have:
[tex]\mathbf{80 = 2(l + 20)}[/tex]
Divide both sides by 2
[tex]\mathbf{40 =l + 20}[/tex]
Subtract 20 from both sides
[tex]\mathbf{l = 20}[/tex]
This means that, the length and the width are equal (i.e. 20 ft)
Hence, the special rectangle is a square

Step-by-step explanation:
The probability of a podiatrist examining six people until he finds the first patient who has bunions is [tex](0.76)^5[/tex] (0.24).
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
We have,
24% of people who get their feet examined are found to have bunions.
let p= 24%= 0.24
and, q= 1-p = 1-0.24 = 0.76
When he examines 6 people before he sees a patient with an bunions, the event is represented as:
P = ([tex]q^5[/tex]) p
= [tex](0.76)^5[/tex] (0.24)

Step-by-step explanation:
EFG + EGD + DGC = 180 since the form a straight line
EGD = 30 since it is a vertical angle to AGB = 30
DGC = 50
Substitute these values in

Tim is building a model of a castle with small wooden cubes. So far Tim has constructed part of a security world castle,as shown below. Each wooden cube has a side length of 1/8ft
Based on the model,the length of the wall is ___ft, the width of the walk is 1/2 ft, and the height of the wall is ___. The volume of the portion of security wall that Tum has constructed so far is ___ cu ft.
Answer:
Based on the model,the length of the wall is 9/8 ft, the width of the walk is 1/2 ft, and the height of the wall is 11/8. The volume of the portion of security wall that Tim has constructed so far is 99/128 cu ft.
Step-by-step explanation:
In the picture attached, part of a security world castle is shown.
length: 9 blocks, which is equivalent to 9*(1/8) = 9/8 ft
height: 11 blocks, which is equivalent to 11*(1/8) = 11/8 ft
width: 1/2 ft
Volume: length*height*width = (9/8)*(11/8)*(1/2) = (9 * 11 * 1)/(8 * 8 * 2) = 99/128 cu ft
Based on the model, the length of the wall is 9/8 ft, the width of the walk is 1/2 ft, and the height of the wall is 11/8. The volume of the portion of security wall that Tim has constructed so far is 99/128 cu ft.
Tim is building a model of a castle with small wooden cubes. Each wooden cube has a side length of 1/8 ft. Given the following information, we will solve the problem step by step:
Length of the Wall
Assuming we know the total number of cubes used to form the length of the wall, we can multiply the number of cubes by the side length of each cube (1/8 ft) to obtain the length in feet.
Width of the Wall
We are given that the width of the wall is 1/2 ft.
Height of the Wall
If we assume that the wall height in the model is given in terms of the number of cubes stacked, we can multiply that number by 1/8 ft per cube to determine the total height in feet.
Volume of the Security Wall
To find the volume, we will assume there is a certain number of cubes used for the entire structure. The volume of a cube with side length 1/8 ft is:
Volume of one cube = (1/8 ft)³ = 1/512 cu ftThe total volume of the wall is then the volume of one cube multiplied by the total number of cubes used.
Therefore, to complete the details:
Length of the wall = Number of cubes in length direction [tex]\times[/tex] 1/8 ftWidth of the wall = 1/2 ftHeight of the wall = Number of cubes in height direction [tex]\times[/tex] 1/8 ftVolume of the security wall = Total number of cubes [tex]\times[/tex] 1/512 cu ftEnsure you have the number of cubes to accurately determine the final measures.
