A plumber $25 per hour of work plus a one-time $90 service call fee. which function represents y, the total cost of hiring the plumber for x hours?
What is the value of x?
The value of x is given as follows:
x = 13.7.
How to obtain the value of x?The value of x is obtained using similar triangles, which share these two following features:
Congruent angle measures.Proportional side lengths.The proportional side lengths are given as follows:
x and 16.6 and 7.Hence the proportional relationship of these lengths is given as follows:
x/16 = 6/7.
Meaning that the value of x is obtained as follows:
7x = 16 x 6
x = 16 x 6/7
x = 13.7.

What is the value of x? responses x = 4. 8 cm x, = 4. 8 cm x = 30 cm x, = 30 cm x = 93 cm x, = 93 cm x = 187. 5 cm x , = 187. 5 cm.
Using the equation we know that the required value of x is (B) 30 cm.
What are equations?Basically, an equation is when you have two expressions with the same value on either side of an "equal to" sign.
For example, 3x + 5 = 15.
There are lots of different types of equations, like linear, quadratic, and cubic, among others.
So, looking at the diagram, the equation is true.
x/75 = 12/30
Solve as follows:
30x = 12 * 75
30x = 900
30x/30 = 900/30
x = 30
Therefore, using the equation we know that the required value of x is (B) 30 cm.

What are the 5 coordinate systems?
The 5 coordinate systems are Cartesian Coordinate System, Polar Coordinate System, Cylindrical Coordinate System, Spherical Coordinate System, Elliptic Coordinate System.
1. Cartesian Coordinate System: This system uses two perpendicular axes (X and Y) to determine the location of a point. The point's coordinates are the distances from the origin point (0, 0). The axes divide the plane into four quadrants and the coordinates can be positive or negative. The axes are also referred to as the x-axis and y-axis.
2. Polar Coordinate System: This system uses an angle and a distance from a fixed origin point to specify a point. The angle is measured in radians and the distance is measured from the origin. The coordinates of the point are usually written as (r, θ).
3. Cylindrical Coordinate System: This system combines the two-dimensional polar system and the one-dimensional Cartesian system. It uses three coordinates, (r, θ, z) to determine a point's location in three-dimensional space. The r coordinate is the distance from the origin, θ is the angle measured from the z-axis, and z is the height.
4. Spherical Coordinate System: This system uses three coordinates, (r, θ, φ), to determine a point's location in three-dimensional space. The r coordinate is the distance from the origin, θ is the angle measured from the z-axis, and φ is the angle measured from the x-axis.
5. Elliptic Coordinate System: This system uses two coordinates, (a, b), to specify a point on an ellipse. The a coordinate is the distance from one of the ellipse's foci, and the b coordinate is the distance from the other. This system is useful for describing orbits, such as those of planets.

What are the Slope and intercepts ?
In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction of function
The slope expresses how quickly the dependent variable changes when the independent variable changes. The Greek capital letter D or D is frequently used by mathematicians and economics to represent change. Slope contrasts the change in the vertical axis, y, with the change in the horizontal axis, x.
On the x-axis, negative numbers are below the origin, and on the y-axis, they are to the left of the origin. If the x-value is negative, begin at the origin and go to the left; if the y-coordinate is negative, move downward.
Line graphs, also known as XY graphs, are used to visually represent data (the outcomes of an experiment) in order to demonstrate the link between various factors, such as the severity of the disease and time.

What happens to an image when it is enlarged using scale factor between 1 and 1?
When an image is enlarged using a scale factor between 1 and 1, the image does not change in size.
A scale factor of 1 means that the image is not being enlarged or reduced in size; it is remaining the same size. Therefore, the image will appear the same as it did before the enlargement.
A scale factor of less than 1 means that the image is being reduced in size, and a scale factor greater than 1 means that the image is being enlarged in size. But when it comes to scale factor between 1 and 1, the image will not change in size, it will appear the same as it was before.
It's important to note that when you're enlarging an image using a scale factor that's less than 1, the image becomes smaller but when you're using a scale factor greater than 1 the image becomes larger.

A man deposited $1200 in his bank account. A simple interest of 20% per annum was paid on his deposit.
a. For calculating simple interest for the 4 years
We have been given data as:
Principal (P) = $1200
Rate of Interest (R) = 20%
Time (T) = 4 years
⇒ Simple interest = P × R × T
Substitute the value of P, R, and T in the above formula,
The simple interest for 4 years would be:
⇒ 1200 x 20% x 4 = 960

It costs $4 for 2 visits, $8 for 4 visits, $10 for 5 visits, and $16 for 8 visits.
Fill in the table to find how much it costs for 2, 4, 5, and 8 visits ?2 visits: c = 2v = 2(2) = $4,
4 visits: c = 2v = 2(4) = $8,
5 visits: c = 2v = 2(5) = $10,
8 visits: c = 2v = 2(8) = $16.
Therefore, it costs $4 for 2 visits, $8 for 4 visits, $10 for 5 visits, and $16 for 8 visits.2 visits: c = $30, cost per visit = $15
4 visits: c = $60, cost per visit = $15
5 visits: c = $75, cost per visit = $15
8 visits: c = $120, cost per visit = $15
As seen in the table above, the cost to get your hair done for 2, 4, 5, and 8 visits is $30, $60, $75, and $120 respectively.This means that no matter how many visits you make, the cost per visit stays the same at $15.This is a great deal for customers as they can enjoy the same services for a fixed price.This theory is called the "linear cost model." It is based on the idea that the cost of a product or service is proportional to the number of units that are purchased.In this case, the cost per visit is constant, and the total cost increases in a linear fashion as the number of visits increases.This model is useful for determining the cost of a service or product for a variety of customers, as the cost per unit is known.To learn more about linear cost model refer to:
