What is kilowatt-hour?Kilowatt-hours are units of energy that represent one kilowatt of electricity for one hour (SI symbol: kWh or kWh; typically abbreviated as kWh). It is 3.6 megajoules in terms of standard units (MJ). For electrical energy supplied to customers by electric utilities, kilowatt-hours are a typical billing unit. The abbreviation "kWh," which is derived from the letters kilowatt and hour, stands in for the kilowatt-hour and is a commonly used abbreviation. In addition to being often used in commercial, academic, and scientific publications as well as in the media, it is also frequently employed by electric utility companies to bill consumers for energy delivered to them. One kilowatt (kW) sustained for one hour (multiplied by one) is equivalent to one kilowatt-hour, a composite unit of energy.

Answer:
d = 2
YZ = 16
Step-by-step explanation:
X-Y-Z
so XY + YZ = XZ
11d + (9d -2) = 5d + 28
11d + 9d - 5d = 28 + 2

The cost of 2 kg of mushrooms and 2.5 kg of turnips is £8.55. The cost of 3 kg of mushrooms and 4 kg of turnips is £13.10. Work out the cost of a) 1 kg of turnips. b) 1 kg of mushrooms.
The solution to the system of linear equations shows that the cost of 1 kg of turnips is £ 1.1 and the cost of 1kg of mushrooms is £ 2.9.
System of EquationsA system of equations is the given term of math for two or more equations with the same variables. The solution of these equations represents the point of the intersection.
You can solve a system of equations by substitution or adding methods. In the addition method, you eliminate a variable, on the other hand, in the substitution method you replace a variable for the other.
First, you should convert the text of the problem into equations, thus you can write:
2m + 2.5t = 8.55 (1)
3m + 4t = 13.10 (2)
where: m = mushrooms and t = turnips
For solving this question, you can apply the addition method. Thus, you should follow the steps below:
Multiply equation 1 by 3 and equation 2 by -2, thus you can rewrite the equations as shown below6m + 7.5t = 25.65 (1)
-6m -8t = -26.20 (2)
Sum equations 1 and 2 and find t-0.5t = -0.55
0.5t = 0.55
Finding mFrom equation 1, you have 6m+7.5t=25.65 . If t= 11/10, you have
6m + 7.5*11/10 = 25.65 * (100)
600 m + 825 = 2565
600 m = 2565 -825
600 m = 1740
m = 1740/600
m=29/10
m=2.9
From the previous steps, you have the answers for the letter a ( £ 2.9 ) and the letter b ( £ 1.1).

Two motorcyclist start at the same point and travel in opposite directions. One travels 8 miles an hour faster than the other. In 3 hours they are 288 miles apart how fast is each traveling
Answer:
One motorcycle was going 44 miles and hour and the other motorcycle was going 8 miles an hour faster, so it was going 52 miles per hour.
Step-by-step explanation:
Distance = rate times time
Both motorcycles have a time of 3. We do not know the rates, but we know that one motorcycle's rate was 8 miles an hour faster. Let's call motorcycle 1's rate x then motorcycle 2's rate must be (x + 3)
Motorcycle 1
d = 3x
Motorcycle 2
d = 3(x +8)
We know that the total distance together is 288
3x + 3(x+8) = 288 Distribute the 3
3x + 3x + 24 = 288 Combine the 3's
6x + 24 = 288 Subtract 24 from both sides of the equation
6x = 264 Divide both sides by 6
x = 44
One motorcycle was going 44 miles and hour and the other motorcycle was going 8 miles an hour faster, so it was going 52 miles per hour.

What is the inequality represented?
(i got it graphed like what i have already but I don't know if its right even thought i gotten it)
Using the equation of the parabola, the inequality represented is:
y ≥ -(x + 2)² + 8.
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
For this problem, the vertex is at (-2,8), hence:
h = -2, k = 8.
y = a(x + 2)² + 8.
The y-intercept is of (0,4), when when x = 0, y = 4, which we use to find a as follows:
4 = 4a + 8
4a = -4
a = -1.
Hence the parabola is:
y = -(x + 2)² + 8.
The exterior of the parabola is shaded, that is, the part that is above the concave down parabola, hence the inequality is:
y ≥ -(x + 2)² + 8.

Inference is referred to as all the data collected in a particular study.
What is inference?Etymologically, the word "infer" means to "carry ahead." Inferences are stages in reasoning that connect premises to logical conclusions. The dichotomy between deduction and induction in inference theory, which dates at least to Aristotle in Europe, is a classic one (300s BCE). Deduction is inference that results in logical conclusions from premises that are known to be true or that are presumed to be true, while the logic of correct inference is investigated. A universal conclusion is inferred by induction from specific evidence. Contradistinguishing abduction from induction, Charles Sanders Peirce is credited with identifying a third sort of inference. Researchers in the domains of logic, argumentation studies, and cognitive psychology traditionally study human inference (i.e., how people draw conclusions); artificial intelligence researchers create automated inference systems to mimic human inference.

What is regression?Regression is a statistical technique used in the fields of finance, investing, and other disciplines that aims to establish the nature and strength of the connection between a single dependent variable (often represented by Y) and a number of independent variables (known as independent variables).
The most popular variation of this method is linear regression, which is also known as simple regression or ordinary least squares (OLS).
Linear regression determines the actual linear relationship between two variables based on a line of best fit. As a result, the slope of a straight line was used to depict linear regression indicating how altering one variable impacts modifying another. In a linear regression connection, the value of one variable when the value of the other is zero is represented by the y-intercept.

Malcolm got his first job. His wage in his first year was $12.50 an hour. In year 2, it was raised to $13.20 an hour. What was the percent increase in his hourly wage between year 1 and year 2?
Answer:
5.6%
Step-by-step explanation:
1) Find the difference between the initial and final values
In this case, a man's hourly wage increased from $12.50 to $13.20. The difference between the hourly wages is $13.20 - $12.50 = $0.70.
2) Divide the difference by the initial value
$12.50 is the initial hourly wage
($0.70 ÷ $12.50) = 0.56
3) Convert the quotient to a percentage
0.56 x 100 = 56%
The man's hourly wage increased by 56%.
Hope this helps, have a great day!
The percentage is the change with respect to the original amount increase in his hourly wage between year 1 and year 2 will be 5.6%.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
As per the given,
The hourly wage in year 1 = $12.50 an hour
The hourly wage in year 2 = $13.20 an hour
Percentage = change / initial
Percentage = (13.20 - 12.50)/12.50
Percentage = 0.7/12.50
Percentage = 0.056
⇒ 0.056 × 100 = 5.6%
Hence "The percentage is the change with respect to the original amount increase in his hourly wage between year 1 and year 2 will be 5.6%".

The location of the midpoint of the line segment is (37 / 2, 11 / 2).
How to determine the location of the midpoint in a line segment
According to the statement, the position of the two endpoints of a line segment are known and we must determine where the midpoint is, that is, the point such that the line segment is divided into two parts of equal length. The location of the midpoint is found by means of the midpoint formula:
M(x, y) = 0.5 · B(x, y) + C(x, y)
Where M(x, y) is the midpoint.
If we know that B(x, y) = (15, 7) and C(x, y) = (22, 4), then the location of the midpoint is:
M(x, y) = 0.5 · (15, 7) + 0.5 · (22, 4)
M(x, y) = (15 / 2, 7 / 2) + (11, 2)

The area of a triangle is [tex]\frac{1}{2} (bh)[/tex].
The height is already given: 8
But we need to find the base and since the hypotenuse is given and it's a right triangle, we can use the pythagorean theorem. (Hypotenuse is longest, slanted side of a right triangle)
The pythagoren theorem is [tex]a^2+b^2=c^2[/tex] where a and b are the sides, and c is the hypotenuse.
Plugging in the given values => [tex]8^2+b^2=10^2[/tex]
We have to solve for b. So, squaring 8 and 10 we get [tex]64+b^2=100[/tex].
Next, subtract 64 from both sides to get b by itself: [tex]b^2=36[/tex]
Square root both sides to get [tex]b=6[/tex].
Now that we have our base we can plug it in to the area of triangle formula: [tex]1/2(6*8)[/tex].

Solve system of equations.
y=2 x
y=-x+6
The system of equations involving y = 2x and y = -x + 6 has the solution (2 , 4).
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in x and y,
y = 2x (equation 1)
y = -x + 6 (equation 2)
Since both equations are in the form of y in terms of x ans dome constant, substitute the first equation to the second equation.
y = -x + 6 (equation 2)
2x = -x + 6
Combining the all terms containing the variable x on one side and the constants on the other side of the equality, and solving for x.
2x + x = 6
3x = 6
x = 2
Substituting the value of x in the first equation,
y = 2x (equation 1)
y = 2(2)
y = 4
Writing it as an ordered pair, we got (2 , 4) as the solution of the system of equations involving y = 2x and y = -x + 6.

change in Ted's net pay per paycheck, after taxes, if his new
federal withholding per week is $75.
Ted's net pay per week after the taxes is $559.09
Net Pay:
Net pay means take-home pay or the amount employees earn after all payroll deductions are subtracted from their gross pay.
Given,
Ted works as a travel guide for a mountain resort, earning $15.72 per hour. Ted is paid weekly, and works 40 hours in one week. His current federal withholding per week is $69. He works in a state with a flat-rate income tax of 4.63%. He will receive a raise of 5% of his hourly rate.
Here we need to find the Ted's net pay per paycheck, after taxes, if his new federal withholding per week is $75.
Through the given details we know that,
Per hour pay = $15.72
Total work per week = 40
So, the total amount for a week is
=> 15.72 x 40
=> $628.8
After federal withholding tax, then the amount is
=> $628.8 - 69
=> $559.8
Now the tax is 4.63%, then
=> $559.8 x 4.63%
=> $559.8 x (4.63/100)
=> $25.91
So, the remaining amount is
=> $559.8 - $25.91
=> $533.88
Now, he will receive 5% for his hourly rate,
Then,
=> $15.72 x (5%)
=> $15.72 x (5/100)
=> 0.78
So, the increased amount is
=> $16.5
Now, the net pay is,
=> (16.5 * 40) - (75 + 25.91)
=> 660 - 100.91
=> 599.09
So, Ted's net pay per paycheck, after taxes is $559.09.
