I am only doing 15 points because I have asked questions and they just take advantage of the points and don't actually answer the question.

Mrs. Jones husband thought he could fix the clogged sink drain. In doing so he lost the drain snake down the pipe and had to call a plumber. Roto-Rooter charged a $50 home visit fee and an hourly rate of $35 an hour.

Write an equation in slope-intercept form to represent the total cost of the plumbers fees.
y represents the total cost and x represents the number of hours.



Write another equation where t represents the total cost and h represents the number of hours.



What does the y-intercept represent in this problem?



What does the slope represent in this problem?




The plumber was at Mrs. Jones house for 4 hours. What is the total cost for the plumbers visits?

Answer:

Shorter than 15IN, 5.9 or 6 inches

Hope this helps:)

Step-by-step explanation:

The ribbon is shorter than 15 inches, and its length is approximately 5.91 inches.

Given that a ribbon has a length of 15 cm, we need to calculate the length in inches,

To determine the length of the ribbon in inches, we need to convert the length from centimeters to inches.

To convert centimeters to inches, we can use the conversion factor 1 inch = 2.54 centimeters.

The length of the ribbon is 15 centimeters. To convert this to inches, we divide 15 by 2.54:

15 cm / 2.54 cm/inch = 5.91 inches (rounded to two decimal places).

So, the ribbon is shorter than 15 inches.

The ribbon is approximately 5.91 inches long.

Answer:

x=2

Step-by-step explanation:

x+(-4) is the same as x-4

First you have to get X alone so you add 4 to both sides because when you add 4 to both sides it will take away the 4 on the x side.

x-4=-2

+4    +4

x= -2+4                or you can see this as 4-2 which is 2

x=2

Answer:

Density is defined as mass per unit volume:

density = mass/volume

Density can be calculated using the mathematical formula (expression):

d = m ÷ V

where d = density, m = mass, V = volume

The greater the density, the more mass per unit volume.

The unit of density derived from SI units is kilograms per cubic meter, kg/m3 or kg m-3.

More commonly, densities are given in g/mL (g mL-1) or g/cm3 (g cm-3 or g/cc).

Density is a characteristic property of pure substances so density can help identify a particular pure substance.

Since different substances have different densities, density can also be used to separate one substance from another.

In general, solids are more dense than liquids which are more dense than gases:

density of solid > density of liquid > density of gas

Step-by-step

Answer:

0.338 g/mL

Step-by-step explanation:

Density is the mass per unit volume of any object. It is calculated by dividing the mass of an object by its volume. This is:

ρ = m/V

ρ = 4.05 g  / 12 mL

ρ = 0.3375 g/mL

ρ ≅ 0.338 g/mL

Mathematics includes the study of such topics as quantity, structure, space, and change. It has no generally accepted definition. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof.

Step-by-step explanation:

Mathematics is the study of numbers, shapes and patterns. The word comes from the Greek word "μάθημα" (máthema), meaning "science, knowledge, or learning", and is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada). ... Numbers: how things can be counted.

Therefore, Mathematics is the abstract study of topics such as quantity (numbers), structure, space, and change!

Answer:

For the first one

x= About 32.02

y= About 27.58

z= About 55.16

For the second one

x= 6

y= 12

z= about 16.97

Step-by-step explanation:

Their all really simple

These are special right triangles, a 45, 45, 90 and a 30, 60, 90 triangle. The formla for these triangles are shown in the picture below.

Now for the first one ]

Lets find Z first

Now this is a 45 special right triangle so we know the other side s 39 but the hypotenuse is n[tex]\sqrt{2}[/tex] (I’m using N becuase x and y is taken) So n is basically 39 (look at the image below) and just solve that. Now for x and y. We know its a 30, special right triangle. We know that 39 here is already the answer for  N[tex]\sqrt{3}[/tex] so make an equation to find the n and you’ll get 27.58 for y. Now For x, its just doubled the y.

For the second one this is easier

We know that the x is (6) becuase its already in the radical number, now to find the hypotnuse, we double that and get 12. Now we know what y is becuase since the 2nd triangle is a 45/45/90, we know that 12 is y, the hypotnuse is just N[tex]\sqrt{2}[/tex] and we just plug in the n with 12 and solve it!

The graphical function representation of a function, represents the mapping of the domain of the function to the range of the function

The sum of the coordinates of the point is 7.25

The reason the above values are correct is as follows;

The given parameter is;

The point (9, 7) is on the graph y = f(x)

Required:

A point on the graph, 2·y = (f(2·x)/2) + 2

Solution:

Let x = 9/2, given that (9, 7), is on the graph, f(x), we get;

f(2·x) = f(2 × 9/2) = f(9) = 7

Therefore;

2·y = (f(2·x)/2) + 2 = (7/2) + 2) = 5.5

y = 5.5/2 = 2.75

y = 2.75

The coordinate of the point is (x, y) = (2.75, 9/2)

The sum of the coordinates of the point is 2.75 + 9/2 = 7.25
