According to the equation, the monthly fee that Sara paid was $60.

Let's start by assigning some variables. Let x be the monthly fee that Sara paid and let y be the number of months that Sara was a member of the gym. We know that Sara paid $15.95 to become a member, so her total cost can be represented by the equation:

Total Cost = Initial Cost + Monthly Fee x Number of Months

$735.95 = $15.95 + x x y

Now we have an equation with two variables. To solve for x, we need to isolate it on one side of the equation. We can do this by subtracting $15.95 from both sides of the equation:

$720 = x x y

Next, we need to solve for x. Since we don't know the value of y, we can't solve for x directly. However, we do know that Sara was a member for 12 months, so we can substitute y = 12 into the equation:

$720 = x x 12

Now we can solve for x by dividing both sides by 12:

$60 = x

To determine the number of sheets of cardboard in a stack, we need to use the information given in the problem.

We know that each sheet of cardboard is 1 inch thick, and 16 sheets are stacked on top of each other in packages. The height of each stack is 21 inches.

Using the model of a ruler, we can divide the height of the stack (21 inches) by the thickness of each sheet (1 inch) to find the number of sheets in the stack.

21 ÷ 1 = 21

So, there are 21 sheets of cardboard in a stack.

To write an expression that can be used to determine the number of sheets of cardboard in a stack, we can use:

Number of sheets = height of stack ÷ thickness of each sheet

Or, substituting the given values: Number of sheets = 21 ÷ 1 = 21

This expression is simply a representation of the model we used earlier. It shows that we can determine the number of sheets in a stack by dividing the height of the stack by the thickness of each sheet. In this case, the expression yields the same result as the model, which is 21 sheets.

A scatter plot is a graphical representation of a set of data points that displays the relationship between two variables.

How to solve the question?

The plot uses a Cartesian coordinate system, with one variable plotted on the x-axis and the other on the y-axis. Each data point is represented by a dot, with its location on the plot determined by its values for the two variables. The pattern of the dots on the plot gives insight into the relationship between the two variables.

Scatter plots are useful for visualizing the strength and direction of a relationship between two variables. A positive relationship between the variables means that as one variable increases, the other variable also increases. In contrast, a negative relationship means that as one variable increases, the other variable decreases. A scatter plot can also help to identify any outliers or unusual data points.

Scatter plots can be used to analyze many types of data, including scientific data, financial data, and social data. They can be used to identify trends, correlations, and patterns that might not be immediately apparent from a simple numerical analysis of the data. Scatter plots are a valuable tool for data analysis and visualization, and are widely used in scientific research, data analysis, and data-driven decision making.

From the attached picture, it is proven that the diagonals of rectangle MNOP are congruent.

To show that the diagonals of rectangle MNOP bisect each other, we need to show that they intersect at their midpoint. Let's label the diagonals as AC and BD, where AC is the diagonal that goes from vertex M to vertex O, and BD is the diagonal that goes from vertex N to vertex P.

First, let's find the midpoint of AC. The midpoint of a line segment is the point that is exactly halfway between the two endpoints. The endpoints of AC are M and O, so we can find the midpoint by averaging their x-coordinates and y-coordinates:

midpoint of AC = ((Mx + Ox)/2, (My + Oy)/2)

Similarly, we can find the midpoint of BD:

midpoint of BD = ((Nx + Px)/2, (Ny + Py)/2)

Now we need to show that these midpoints are the same point. That is, we need to show that:

((Mx + Ox)/2, (My + Oy)/2) = ((Nx + Px)/2, (Ny + Py)/2)

To do this, we can set the x-coordinates equal to each other and the y-coordinates equal to each other:

(Mx + Ox)/2 = (Nx + Px)/2

(My + Oy)/2 = (Ny + Py)/2

Now we can solve for the values of x and y. First, we'll solve for x:

Mx + Ox = Nx + Px

2Mx + 2Ox = 2Nx + 2Px

Mx + Ox - Nx - Px = 0

(Mx - Nx) + (Ox - Px) = 0

Similarly, we can solve for y:

My + Oy = Ny + Py

2My + 2Oy = 2Ny + 2Py

My + Oy - Ny - Py = 0

(My - Ny) + (Oy - Py) = 0

Now we can see that the x-coordinate and y-coordinate of the midpoint of AC are equal to the x-coordinate and y-coordinate of the midpoint of BD, respectively. Therefore, the diagonals of rectangle MNOP bisect each other.

To show that the diagonals are congruent, we can use the Pythagorean theorem. Let's label the length of AC as a and the length of BD as b. Then we have:

a^2 = OM^2 + ON^2 (by the Pythagorean theorem in triangle OMN)

b^2 = PN^2 + PO^2 (by the Pythagorean theorem in triangle PON)

But we know that OM = ON and PO = PN, since MNOP is a rectangle. Therefore, we can simplify these expressions:

a^2 = 2OM^2

b^2 = 2PO^2

Since OM = PO (they are opposite sides of a rectangle), we can substitute to get:

a^2 = 2OM^2 = 2PO^2 = b^2

Therefore, a = b, and the diagonals of rectangle MNOP are congruent.

Set bytes = file_size_in_mb * 1000000

Set result = round((bytes / 1048576), 2)

Output "There are " + result + " MB " + bytes + " bytes".

the given equation y = 2.81x² represents a non-proportional situation because the output variable y is not directly proportional to the input variable x.

HOW TO SOLVE THE QUESTION?

The given equation y = 2.81x² represents a non-proportional situation because the output variable y is not directly proportional to the input variable x. In a proportional relationship, when one variable increases or decreases, the other variable changes in direct proportion to it. However, in this equation, the output variable y increases at a non-linear rate as the input variable x increases.

A proportional relationship between two variables is characterized by a constant ratio between the two variables, which means that if one variable is doubled, the other variable is also doubled. In this case, the coefficient of x² is not a constant value, which indicates that the ratio between y and x² is not constant. Therefore, the given situation is not proportional.

Furthermore, a non-proportional relationship between two variables may exhibit a curved or nonlinear relationship between the variables, as in the case of this equation where y increases at an increasing rate as x increases. Therefore, the given situation can be categorized as non-proportional.

In conclusion, the given equation y = 2.81x² represents a non-proportional situation because the output variable y is not directly proportional to the input variable x.

Answer: 729

Step-by-step explanation:

3^2 is the same has 3 to the power of 2

9^2 is the same as 9 to the power of 2

When you see an expression like 3^2 x 9^2, it means you must raise 3 and 9 to the power of 2, multiply those numbers, and then do it again.

3 raised to the power of 2, often known as 3 times itself or 3 x 3, equals 9.

9 raised to the power of 2, often known as 9 times itself (9 x 9), equals 81.

As a result, when we change these values in the original expression, we obtain:

3^2 x 9^2 = 9 x 81

Now that we have these two integers, we can easily multiply them to obtain the result:

9 x 81 = 729

Therefore, 729 is the answer to the equation 3^2 x 9^2.

The amount that each girl receives if they receive $200 more than each boy is: $1133.33

We are told that $2800 is shared among four boys and two girls.

Fraction of boys = 4/6 = 2/3

Fraction of girls = 2/6 = 1/3

Amount received by each boy if shared equally = (4/6) * 2800 = $1866.67

Amount received by each girl if shared equally = (2/6) * 2800 = $933.33

Now, each girl gets $200 more than each boy. Thus:
