Sandy works at a clothing store. She makes $9 per hour plus earns 15% commission on her sales. She worked 73 hours over the last two weeks and had a total of $2,830 in sales before taxes.

Which of the following is closest to how much she will earn in hourly wages and commission for those two weeks?

Answer:

$1.41

Step-by-step explanation:

0.20 * 5.8 ounces = $1.16

0.25 * 1.16 = $1.41

The mail  weighing 6.8 ounces cost 145 cents

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given here, the first ounce cost 25 cents and all subsequent ounces or parts of an ounce cost 20 cents each

therefore cost of the first ounce = 25

        and cost of 5.8 ounces = 20× 6

                                                = 120 cents

thus total cost is 120+25 =145 cents

Hence, the  total cost to mail a package is 145 cents

The graph of y² 4x is a parabola with vertex (0,0) and x- and y-intercepts (0,0). The graph opens downward and can be written as y=4x².

The graph of y² 4x is a parabola in the shape of a "U" that opens downward. This parabola can be written in the standard form of y=a(x-h)²+k. In this case, a=4, h=0, and k=0. This means that the equation for the graph of y² 4x is y=4x².

To calculate the graph, we must first determine the vertex, which is the point of the parabola that has the maximum or minimum value. To do this, we use the formula for the vertex of a parabola, which is (h,k)=(-b/2a,f(h)). With a=4 and b=0, the vertex of the parabola is (0,0).

We can then calculate the x-intercepts, which are the points at which the graph of y² 4x crosses the x-axis. To do this, we set y=0 in the equation y=4x² and solve for x. This gives us x=±√(0/4) or x=0. This means that the x-intercepts of the graph of y² 4x are (0,0).

Finally, we can calculate the y-intercept, which is the point at which the graph of y² 4x crosses the y-axis. To do this, we set x=0 in the equation y=4x² and solve for y. This gives us y=0. This means that the y-intercept of the graph of y² 4x is (0,0).

From the question, we are to determine the equation of the line that passes through the given points

We will pick two value pairs from the table

Picking (-4, 9) and (-2, 4)

Using the formula,

(y - y₁) / (x - x₁) = (y₂ - y₁) / (x₂ - x₁)

Then,

(y - 9) / (x - (-4)) = (4 - 9) / (-2 - (-4))

Simplify

(y - 9)/(x + 4) = -5/(-2 + 4)

(y - 9)/(x + 4) = -5/2

Cross multiply

2(y - 9) = -5(x + 4)

2y - 18 = -5x - 20

2y = -5x -20 + 18

2y = -5x - 2

A point is said to be equidistant from two other points when it is at an equal distance away from both of them. For example, the perpendicular bisector of a line segment is equidistant from both endpoints.

A point is said to be equidistant from a set of objects if the distances between that point and each object in the set are equal.

In two-dimensional Euclidean geometry, the locus of points equidistant from two given (different) points is their perpendicular bisector. In three dimensions, the locus of points equidistant from two given points is a plane, and generalising further, in n-dimensional space the locus of points equidistant from two points in n-space is an (n−1)-space.

For a triangle the circumcentre is a point equidistant from each of the three vertices. Every non-degenerate triangle has such a point. This result can be generalised to cyclic polygons: the circumcentre is equidistant from each of the vertices. Likewise, the incentre of a triangle or any other tangential polygon is equidistant from the points of tangency of the polygon's sides with the circle.

The slope of the situation means: B. after the initial rental fee, the paddleboard costs an additional $12 every hour

If a situation is modeled as a linear relationship between two variables, the slope of the relationship is a measure of the strength and direction of the relationship between the two variables in that particular situation.

The slope is calculated as the change in the value of one variable (the "rise") over the change in the value of the other variable (the "run").

For example, consider a situation in which the number of hours that a student studies is related to their grades in a class. The slope of this relationship would indicate the strength and direction of the relationship between hours of study and grades in this particular situation.

A positive slope would indicate that as the number of hours of study increases, the grades also increase, while a negative slope would indicate that as the number of hours of study increases, the grades decrease.

To find the slope of the situation that is represented in the graph given, use two points on the line to calculate the slope.

Using (0, 10) and (2.5, 40)

Slope (m) = change in y / change in x = (40 - 10) / (2.5 - 0)

= 30/2.5

Slope (m) = 12

Relation between base and height of parallelograms is a function  [tex]f(x)=\frac{48}{x}[/tex].

Relations called functions provide an output for each input. The characteristic that every input is associated to exactly one output defines a function as a relation between a set of inputs and a set of allowable outputs. A mapping from A to B will only be a function if every element in set A has one end and only one image in set B. Let A & B be any two non-empty sets.

Based on the values listed in the table for the parallelograms' base length and height, you can see that the base length grows by one unit, giving you the numbers 1, 2, 3, and 4. When base length increases by one unit, height reduces by 1/x, as shown in the following example:

There are countless possible solutions to some equations. In these equations, the equation is true regardless of the value given to the variable. If we try to solve an equation and receive a variable or a number equal to itself, there are infinitely many solutions to the equation.

Single-solution equations:

Some equations only have one precise solution. The variable in these equations can only take on one value in order for the equation to be true. When you solve an equation and the result is a variable equal to a number, you know that the equation only has one solution.

Example: For x, find the solution to the equation 6x-3=21.

6x \s= 24

To both sides, add 3.

x \s= 4

Subtract 6 from both sides.

For a single value of the variable, x=4, the equation is true. Consequently, there is only one solution to the equation 6x-3=21

Non-solvable equations:

There are certain equations with no answers. These equations don't have a value for the variable that would make them true. If you attempt to solve an equation and the result is false, the problem has no solutions.

Example: Solve the equation 4x+12=2x+12+2x.

4x+12

= 2x+12+2x

4x+12

= 4x+12 Combine like terms 2x and 2x.

12

= 12 Subtract 4x from both sides.

Since the equation 12=12 is always true, you can change the value of x to make it true. Therefore, 4x+12=2x+12+2x has an endless number of solutions.

Equations that have infinitely many solutions:

The number of solutions to some equations is limitless. When a variable is used in these equations, any value makes the equation true. If you attempt to solve an equation and it yields a variable or value that is equal to itself, then the equation has an endless number of solutions.

Solve the equation 4x+12=2x+12+2x.

4x+12

= 2x+12+2x

4x+12

= 4x+12 Combine like terms 2x and 2x.

12

= 12 Subtract 4x from both sides

Step-by-step explanation:

The wheelchair ramp creates a right triangle figure. Look at the image I have attached to this response to see the figure.

⭐ What is the "angle of inclination"?

The angle of inclination is the base angle adjacent to the 90-degrees. The angle of inclination is often denoted as θ.

To solve for the angle of inclination, θ, we have to use the inverse of a trigonometric function.

⭐ What trigonometric function do we use?

Look at the side lengths you are given. Are they opposite of θ? Are they adjacent to θ? Are they the hypotenuse of the triangle? Whatever combination of 2 side lengths you have, see what trigonometric function uses those 2 side lengths.

We are given the side length opposite of θ and a side length that is the hypotenuse of the triangle. Therefore, we are going to use the sine function.

⭐ What is the sine function?

sin(θ) = opposite/hypotenuse

Now, we are going to create an equation of the wheelchair ramp using the sine function.

sin(θ) = 5.1/20

Next, find the inverse of the equation. Here is the inverse of the sine function:[tex]sin^{-1} (opposite/hypotenuse) =[/tex]

Let's substitute the opposite and hypotenuse into the inverse of the sine function and solve using a scientific calculator. Make sure to round to the nearest degree.
