Donavon and three friends go to a fair. They each spend one half of their money on rides. Then, they each spend $3 on food. At the end of the day, Donavon and his friends have a total of $8 remaining. How much money did each person bring to the fair?
The question is a mathematics problem requiring solving a two-step equation to find out how much money each person started with, and through logical deduction and equation solving, it's found that every person brought $10 to the fair.
Explanation:The subject of this problem is Mathematics, and it involves solving a two-step equation to find the initial amounts of money each person had. Let's simplify it step by step:
Recognize that there are 4 individuals (Donavon and his 3 friends) spending money. Let's designate the amount of money each person started with as 'X.' They each spend one half of their money on rides. That means they each have X/2 money left.They each then spend $3 on food, so now they each have X/2 - 3 dollarsAfter these expenditures, they're each left with a total of $8. Because there's 4 of them and they each have the same amount left, we have the equation 4 *(X/2 - 3) = 8.Solving this equation, we find that X, the amount of money each person started with, equals $10.Learn more about Two-step equation solving here:https://brainly.com/question/20921293

if the sum of the interior angles of a square is 360,write an equation to show of one interior angle.
Final answer:
To find the measure of one interior angle of a square, divide the total sum of interior angles, 360 degrees, by the number of angles in a square, which is four. The resulting equation is x = 360° ÷ 4, revealing that each angle measures 90 degrees.
Explanation:
The question asks us to write an equation to describe the measure of one interior angle of a square given that the sum of interior angles of a square is 360 degrees.
A square has four equal interior angles. To find the measure of one angle, we can divide the total degrees by the number of angles.
We can set up the equation as follows: Let x be the measure of one interior angle of a square. Then we write the equation x = 360° ÷ 4. When we calculate it, x equals 90 degrees, which means each interior angle of a square is 90 degrees.

75.2 in. ≈≈
cm
To convert 75.2 inches to centimeters, multiply it by the conversion factor of 2.54 cm per inch. 75.2 inches is approximately 191.01 centimeters when rounded to the nearest hundredth.
Explanation:To convert inches to centimeters, you need to use the conversion factor 2.54 cm = 1 inch. The given measurement is 75.2 inches, and you are asked to convert this to centimeters.
You start by setting up the proportion as follows:
1 inch = 2.54 cm75.2 inches = x cmTo find x, you multiply 75.2 by 2.54:
75.2 inches * 2.54 cm/inch = 191.008 cm
Then round this off to the nearest hundredth (if necessary) to obtain:
75.2 in. ≈ 191.01 cm
a three dimensional object grow from witch of the following
check all that apply
A one dimensional objects
B three dimensional
C two dimensional
Three-dimensional objects can grow from both one-dimensional and two-dimensional objects when subjected to thermal expansion, which causes areas and volumes, as well as lengths, to increase with temperature.
Explanation:A three-dimensional object can grow or expand from two-dimensional objects, such as areas (length and width), as well as from one-dimensional objects, such as lengths. When considering thermal expansion in two and three dimensions, it is important to understand that unconstrained objects expand in all dimensions: their areas (two-dimensional) and volumes (three-dimensional), as well as their lengths (one-dimensional), increase with temperature.
For example, if we have a metal plate (a two-dimensional object) with a circular hole in it and we increase the temperature, the area of the plate including the circular hole will increase (Figure 13.11 (a)). Similarly, if we have a solid metal block (a three-dimensional object), its volume will increase with temperature (Figure 13.11 (c)).
The thermal expansion process is explained by the fact that, as temperature increases, the atoms or molecules making up a material move farther apart, causing expansion. This is true for both holes and solid parts of a material, they both grow larger with increased temperature. Therefore, all one-dimensional, two-dimensional, and three-dimensional aspects of an object expand proportional to the increase in temperature.

A cafe only sells two types of sandwiches, turkey and steak. The cafe charges $4 for turkey sandwiches and $6 for steak sandwiches. Last month, the cafe sold $4524 worth of sandwiches. The cafe sold a total of 925 sandwiches.
How many turkey sandwiches did they sell?
Enter your answer in the box.
X = number of turkey sandwiches
Y = number of steak sandwiches
X + Y = 925 total sandwiches sold
4X + 6Y = 4524 dollars made
-4(X + Y = 925)
-4X + (-4Y) = -3700
4X + 6Y = 4524
2Y = 824
Y = 412
X + Y = 925
X + 412 = 925
X = 513 turkey sandwichesx + 2y = 10

By using elimination method, (11,-12) point is the solution to the system of equations.
What is elimination method?"The elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables."
Given system of equations
x + 2y = 10...................(1)
3x + 4y = 8.................(2)
By using elimination method, multiply equation (1) with (3).
Equation (1): 3x + 6y = 30..................(3)
Subtract equation (2) from (3)
3x + 6y - (3x + 4y) = 30 - 8
3x +6y - 3x - 4y = 22
2y = 22
y = [tex]\frac{22}{2}[/tex]
y = 11
Substituting y = 11 in equation (1)
x + 2y = 10
⇒ x + 2(11) =10
⇒ x = 10 - 22
⇒ x = -12
Hence, (11,-12) point is the solution to the system of equations.

Which explains why the graph is not a function?
A.It is not a function because the points are not connected to each other.
B.It is not a function because the points are not related by a single equation.
C.It is not a function because there are two different x-values for a single y-value.
D.It is not a function because there are two different y-values for a single x-value
Answer:- D.It is not a function because there are two different y-values for a single x-value.
Explanation:-
A function is a relation where each input(x) has a single output(y).From the given graph we can see that there are 2 different values of y i.e. y=-2 and y=4 for single x=4.
Therefore, D is the right answer. The graph is not a function because it is not a function because there are two different y-values for a single x-value.
The graph is not a function because there are two different y-values for a single x-value. Option (d) is correct.
Further explanation:
Given:
The options are as follows,
(a). It is not a function because the points are not connected to each other.
(b). It is not a function because the points are not related by a single equation.
(c). It is not a function because there are two different x-values for a single y-value.
(d). It is not a function because there are two different y-values for a single x-value
Explanation:
The output values of the function are known as range and the input values on which function is defined is known as the domain of the function.
The one-to-one function is a function in which every value of the range has exactly one pre-image in the domain.
One-to-one function always passes the vertical line test and the horizontal line test.
The given graph doesn’t pass the vertical line test.

Josephine wants to put a wallpaper border around the ceiling of her room. The dimensions are right there. How many feet of border does she need.
Melissa needs 3.87 feet of string to use as a border for her poster. Melissa finds a piece of string that is 4.25 feet long.
How much string will Mellisa have left over?
Answer
Find out the how much string will Mellisa have left over .
To prove
Let us assume that the string will Mellisa have left over be x .
As given
Melissa needs 3.87 feet of string to use as a border for her poster.
Melissa finds a piece of string that is 4.25 feet long.
Than the equation is write in the form
x = 4.25 - 3.87
x = 0.38 feet
Therefore the string will Mellisa have left over be 0.38 feet .
Hence proved
The length of string Mellisa will have left over is 0.38 feet
From the question,
We are to determine how much string Mellisa would have left over.
From the given information
Melissa needs 3.87 feet of string to use as a border for her poster.
Then,
She finds a piece of string that is 4.25 feet long.
That means,
From the piece of string that she found, she will use 3.87 feet out of the 4.25 feet.
∴ The length of string Mellisa will have left is = 4.25 feet - 3.87 feet
The length of string Mellisa will have left is = 0.38 feet
Hence, the length of string Mellisa will have left over is 0.38 feet
