Approximately 24.1% of Kelly's taxable income is her tax.

What is percent?

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.

To determine what percent of Kelly's taxable income is her tax, we need to calculate her tax liability first.

Assuming that Kelly files as a single taxpayer with no dependents and takes the standard deduction, her taxable income of $50,000 falls into the 22% tax bracket for the year 2021.

Using the IRS tax tables for 2021, Kelly's tax liability would be approximately:

$9950 + (0.22 * ($50,000 - $40,525)) = $9950 + $2095.50 = $12045.50

Therefore, Kelly's tax liability is approximately $12,045.50.

To calculate what percent of her taxable income is her tax, we can divide her tax liability by her taxable income and multiply by 100:

($12,045.50 / $50,000) * 100 = 24.09%)

Therefore, approximately 24.1% of Kelly's taxable income is her tax. Rounded to one tenth of a percent, this is 24.1%.

Answer:

-5≤y≤17

Step-by-step explanation:

Answer: -5 to 17 degrees

Step-by-step explanation:

When two distinct lines, l and m, are each perpendicular to the same line n, it means that the two lines have the same angle of rotation in relation to n.

An angle is a figure formed by two lines or rays diverging from a common point. It is measured in degrees, with a full circle representing 360 degrees. Angles are used to describe the direction and orientation of objects, as well as to measure the size of an area or the relationship between two lines. Angles are an important part of mathematics, used in problems such as geometry, trigonometry and calculus.

This angle is equal to 90 degrees, meaning that the two lines are parallel to one another.

Parallel lines are lines that never intersect and are always the same distance apart. This is the case for l and m because both lines are perpendicular to the same line n and, thus, have the same angle. Therefore, the two lines are parallel to one another, meaning that they will never cross and will always remain the same distance apart.

Therefore , the solution of the given problem of equation comes out to be the system of equations has an answer of x = 5 and y = -2.

Mathematical formulas frequently use the same variable letter to try to enforce harmony among two assertions. Many academic numbers are shown to be equal using mathematical expression, also known as assertions. In this case, instead of splitting 12 into two parts, the normalise adds b + 6 using the example of y + 6. It is possible to determine the link number between each sign portion and the line length.

Here,

One of the solutions for a single variable should be solved in terms of the other.

We can find x from the first solution by solving in terms of y:

=> 2x + 3y = 4

=>  2x = 4 - 3y

=>  x = (4 - 3y)/2

Solve for the other variable by substituting the formula for the variable from step 1 into the other equation.

Change x in the second expression to (4 - 3y)/2:

=>  2x = 7y + 24

=>  2((4 - 3y)/2) = 7y + 24

=>  4 - 3y = 7y + 24

=> -10y = 20

=> y = -2

Solve for the other variable by substituting the value of the variable from step 2 into one of the initial formulae.

When the first solution is used:

=> 2x + 3y = 4

=> 2x + 3(-2) = 4

=> 2x - 6 = 4

=> 2x = 10

=> x = 5

As a result, the system of equations has an answer of x = 5 and y = -2.

On the opening day of the exhibition, 30 adult tickets were sold.

Let's use the following variables to represent the number of adult and child tickets sold:

a: the number of adult tickets sold

c: the number of child tickets sold

From the problem, we will use linear equation system. we know that the total number of tickets sold is 80, so we have:

a + c = 80 (Equation 1)

We also know that the total revenue from ticket sales is $180, so we have:

3a + 2c = 180 (Equation 2)

We can use Equation 1 to solve for one of the variables in terms of the other:

c = 80 - a

Substituting this into Equation 2, we get:

3a + 2(80 - a) = 180

Simplifying this equation, we get:

a + 160 = 90

a = 30

Rotation: Rotate the larger circle by the same angle as the smaller circle around the origin. Rotate the smaller circle by any angle. Although changing direction, this metamorphosis keeps the shape and size intact.

Any point in the plane that is a certain distance from another point forms a circle (center). Thus, it is a curve formed up of points that are separated from one another by a predetermined distance in the plane. Moreover, at every angle, it is rotationally symmetric about the centre. The closed, two-dimensional plane of a circle has every pair of points equally separated from the "centre." By drawing a line through the circle, one can create a line of circular symmetry. Moreover, at every angle, it is rotationally symmetric about the centre.

If two circles have the same shape but different sizes, they are comparable. The circles are centred at the origin in this case, allowing us to compare their radii to see if they are equal. The ratio of the larger and smaller circles' radii is 8/2, or 4.

Translation: Move the smaller circle to the origin and the larger circle in the same direction to a place four times away from the origin. While changing location, this transformation keeps the object's shape and size.

Answer:

To work out the pressure that the car exerts on the road, we need to divide the force by the area of contact between the car and the road.

Since each of the car's 4 tyres has an area of 0.03 m² in contact with the road, the total area of contact is:

Total area of contact = 4 × 0.03 m² = 0.12 m²

So, the pressure that the car exerts on the road can be calculated as:

Pressure = Force / Area of contact

Pressure = 15,600 N / 0.12 m²

Pressure = 130,000 N/m²

Therefore, the pressure that the car exerts on the road is 130,000 N/m².

Answer:

$6141

Step-by-step explanation:

We can use the formula for compound interest to find the amount in the account after 18 years:

A = P(1 + r/n)^(nt)

Where:

A = the amount in the account after 18 years

P = the principal amount (initial deposit) = $3000

r = the annual interest rate = 4% = 0.04

n = the number of times the interest is compounded per year = 4 (quarterly)

t = the time in years = 18

Plugging in these values, we get:

A = 3000(1 + 4%/4)^(4*18)

A = 3000(1.01)^72

A = 3000*2047

A = 6141

Rounding to the nearest whole number, we get:

A = $6141

Therefore, there will be $6141 in the account on the child's 18th birthday.

The rule is to minus 4 from the x-coordinate and add 8 to the other. The coordinates of A after the reflection are (-x,y). Thus, it is present to the left of the Y-axis. Yes, the final figure is congruent to the original figure.

To translate a point 4 units left and 8 units up, we subtract 4 from the x-coordinate and add 8 to the y-coordinate.

Now, let’s apply this rule to point A. If A has coordinates (x,y), then after translation it will have coordinates (x-4,y+8).

For the second question, we can find the new location of A by using the coordinates we just found. So if A was originally located at (x,y), it will now be located at (x-4,y+8).

To reflect a point over the y-axis, we negate its x-coordinate. So if A has coordinates (x,y), then after reflection it will have coordinates (-x,y).

Using this rule, we can find that after reflection over y-axis, point A will have coordinates (-x,y).

Finally, since translation and reflection are both rigid transformations, they preserve distance and angles between points. Therefore, the final figure is congruent to the original figure.

There are 9 choices for the first person, 8 choices for the second person (since one chair is already taken), 7 choices for the third person, and so on. Therefore, the total number of ways 6 people can be seated in a row of 9 chairs is:

[tex]9 * 8 * 7 * 6 * 5 * 4 = 60,480[/tex]

So there are 60,480 ways to seat 6 people in a row of 9 chairs.

To count the number of ways 6 people can be seated in a row of 9 chairs, we can use the multiplication principle of counting.

First, we consider the number of choices for the first person. Since there are 9 chairs and the order in which the people are seated matters, there are 9 choices for the first person. Once the first person is seated, there are 8 chairs remaining for the second person to choose from, since one chair is already taken. Therefore, there are 8 choices for the second person. Continuing in this way, there are 7 choices for the third person, 6 choices for the fourth person, 5 choices for the fifth person, and 4 choices for the sixth person.

To find the total number of ways to seat 6 people in a row of 9 chairs, we multiply the number of choices at each step together. Hence, the total number of ways is:

What exactly is a function?

In mathematics, a function is a rule that assigns to each input value (also called the argument) exactly one output value. The input values are typically drawn from a specific set, called the domain of the function, and the output values are drawn from another set, called the range of the function.

Now,

To find (f °g)(12), we need to first evaluate g(12) and then use the result to evaluate f(g(12)).

g(x) = √(x+4), so g(12) = √(12+4) = √16 = 4.

f(x) = 4x+8, so f(g(12)) = f(4) = 4(4) + 8 = 16 + 8 = 24.

Both the arithmetic mean and the weighted mean may be used to determine the average of a group of integers. The sum of all the numbers in the group divided by the entire amount of numbers in the set yields the arithmetic mean. Regardless of significance or relevance, it gives each integer in the set the same amount of weight. On the other hand, the weighted mean gives the integers in the set distinct weights based on their significance or relevance. This indicates that certain numbers in the set provide a greater weighted mean contribution than others.
