The electric usage for a computer repair company was charted over four months. What is the rate of change for the bill during that time? KWH used Billing 578 $109.82 1,033 $196.27 1,475 $280.25 1,754 $333.26 A. $0.56 per KWH B. $1.79 per KWH C. $0.19 per KWH

Answers

Answer 1

Answer:

The correct option is;

C. $0.19 per KWH

Step-by-step explanation:

The given data are;

KWH   [tex]{}[/tex]               Billing

578   [tex]{}[/tex]                 $109.82

1,033   [tex]{}[/tex]               $196.27

1,475   [tex]{}[/tex]               $280.25

1,754   [tex]{}[/tex]               $333.26

Therefore, we have the rate of change, m, given as follows;

m =(Change in the amount paid)/(Change in the electric usage in the same period)

For the first and second month, the rate of change is therefore;

m = ($196.27 - $109.82)/(1,033 - 578) = $0.19 per kWH

Between the first and third month, the rate of change is given as follows;

m = ($280.25 - $109.82)/(1,475 - 578) = $0.19 per kWH

Between the first and fourth month, the rate of change is given as follows;

m = ($333.26 - $109.82)/(1,754 - 578) = $0.19 per kWH

Therefore;

The rate of change is constant and is $0.19 per kWH

1. In the equation y = 2x, what would be the C.O.P ?
2. A graph has the points (2,6) ; (3,9) ; and (5,15)
What is the equation of the graph?​

Answers

9514 1404 393

Answer:

the contant of proportionality is 2y = 3x

Step-by-step explanation:

1. Match the given equation (y = 2x) to the pattern ...

  y = kx . . . . . k is the constant of proportionality

Hopefully, you can see that k corresponds to 2. That is, the coefficient of x is the constant of proportionality. It is 2.

__

2. Since you're studying proportions, it is useful to look at the ratio of the y-value to the x-value. In each case, it is 6/2 = 9/3 = 15/5 = 3. Then the graph shows the variables are proportional, with a constant of proportionality of 3.

  y = 3x

Which graph represents a line with a slope of - į and a y-intercept equal to that of the line y = = x-27
ТУ

Answers

Answer:

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Where m = slope of the line

b = y-intercept

Slope of the line 'm' = -[tex]\frac{2}{3}[/tex]

y-intercept 'b' of the line is equal to the y-intercept of another line given as,

[tex]y=\frac{2}{3}x-2[/tex]

Here y-intercept of the line 'b' = -2

Therefore, the equation of the line will be,

y = (-[tex]\frac{2}{3}[/tex])x + (-2)

[tex]y=-\frac{2}{3}x-2[/tex]

Here negative slope represents a line which is decreasing having y-intercept = -2

Therefore, last graph (bottom) given in the picture will be the answer.

In case you didn't know, there's an order you use to solve these types of questions called the order of operations. You might recognize it as the acronym PEMDAS. PEMDAS is an acronym that stands for the words parentheses, exponents, multiplication, division, addition, subtraction. For example, using the order of operations, the first thing you do is solve inside of parentheses, if there are any. In the problem above, there were parentheses, so that's why we divided inside of it first before multiplying!

Parallel


Neither


Perpendicular

Answers

Answer:

Neither

2y = 3x - 4

y = 2/3x - 3

Step-by-step explanation:

Parallel means the lines never cross. These two lines cross. Perpendicular means they cross and form a 90° angle.

Answer:

Neither

Step-by-step explanation:

Given lines

2y=3x-4 ⇒  y = 3/2x - 4y= 2/3x - 3

The lines have different slope so they intersect but they are not perpendicular as perpendicular lines have negative reciprocal slopes

So the answer choice is neither

Compute the answers for this fish tank containing water.


Compute the mass of water filling this tank.

0.25 g
20 g
250 g

Answers

Answer:

Option (3)

Step-by-step explanation:

Since density on an element = [tex]\frac{\text{Mass}}{\text{Volume}}[/tex]

Volume of the water in the aquarium = volume of the aquarium

                                                              = Length × width × height

                                                              = 10 × 5 × 5

                                                              = 250 cm³

We know density of the water = 1 gram per cm³

By putting these values in the formula,

1 = [tex]\frac{\text{Mass}}{250}[/tex]

Mass = 250 g

Therefore, Option (3) will be the answer.

For the brownie shop:

p = 200m - 2000

200m represents how much money you earn every month. 2000 is how much money you spent to start the business. Multiply 200 by the number of months, then add that number to -2000 to get your profit.

For the smoothie shop:

p = -200 -100m

Same thing as the brownie shop, but 200 is the money spent and 100 is the money earned. Both numbers are negative, so the profit will be more and more negative. This means that, unlike the brownie shop, the smoothie shop isn't gaining any money.

Which describes a type of tax that funds city programs? Oprogressive tax federal income tax Olocal income taax Omedicare tax​

Answers

Answer:

local income tax

Explanation:

The "local income tax" refers to the tax levied to people who are residing or working in a specific local area. This is the tax being used to fund the city programs that will help improve the community.

Such programs include the development of parks in the area, including landscape beautification or enhancement of the public markets, improvement of public schools, etc.

Local income tax may appear as a "withholding tax" in some situations. In this case, it is automatically being withheld from the wage of a worker.
