Answer:
Step-by-step explanation:
To determine what Paul will pay or receive, we need to calculate his total tax liability and compare it to the amount he already paid in federal tax.
For 2021, the tax brackets and rates for individuals filing married separately are as follows:
10% on taxable income up to $9,950
12% on taxable income over $9,950 up to $40,525
22% on taxable income over $40,525 up to $86,375
24% on taxable income over $86,375 up to $164,925
32% on taxable income over $164,925 up to $209,425
35% on taxable income over $209,425 up to $523,600
37% on taxable income over $523,600
First, we need to determine which tax bracket Paul falls into based on his taxable income of $27,205. Since his income is between $9,950 and $40,525, he falls into the 12% tax bracket.
To calculate his total tax liability, we can use the following formula:
(total taxable income) x (tax rate) - (tax credit) = total tax liability
Plugging in the numbers for Paul, we get:
($27,205) x (0.12) - ($1,630) = $2,267.60
Note that we subtract a tax credit of $1,630 since Paul is filing married separately and has taxable income below the phase-out threshold for the credit.
Now, we can compare Paul's total tax liability of $2,267.60 to the $3,410 he already paid in federal tax. Since he paid more than his total tax liability, he will receive a refund of:
$3,410 - $2,267.60 = $1,142.40
Therefore, Paul will receive a refund of $1,142.40 from the federal government.

As per the curve, the area under the shaded region is = 0.4878.
How to find the area of the shaded region?The entire area covered by a flat (2-D) area or the form of an item is known as area. A plane figure's area is the space that is enclosed by its border. The area of a closed figure is the sum of the number of unit squares that cover its surface. Square units like cm² and m² are used to quantify area.
99.7% (or 0.997) of the standard normal curve's entire area, which is 1, is located within three standard deviations of the mean.
The distribution of mean is μ = 0
The distribution of standard deviation is σ = 1
We must determine the area of the shaded zone according to the curve.
That is as follows:
P (-2.25 < Z < 0)
The formula to determine:
= P (Z < 0) - P (Z < -2.25)
Substitute the values in the above equation.
= 0.5 - 0.0122

El punto P está en el exterior de una circunferencia C en el plano. ¿Cuál es el número máximo
de puntos de C que se encuentran a 3 cm de P?
A) 1
B) 2
C) 3
D) 4
E) 8
The correct response is 4. We can consider the following construction to understand why: We drew a 3 cm radio circle with the center located at P. Llamemoso C1.
What exactly is a circle's radio?Half of a circle's diameter corresponds to its radius. The radius equals 5 cm for a 10 cm diameter.
So, in order for C2 to intersect C, the straight line connecting P and C's center must be contained within C2, that is, it must be separated from C's center by a distance less than r. In other words, we need that:
r > d + 3
the distance between the center of C and the straight line connecting P and the center of C is where d. Its distance, d, is same to that between P and the center of C, minus C1's radio. Defined as,
d = PC - 3
where PC denotes the distance between P and C's center.
Thus, we require that:
r > PC - 3 + 3 = PC

Petra is making donuts by stamping circles in dough using a pastry stamp with a radius of 4.25 inches. For the donut hole, she stamps out a circle of dough using a pastry stamp with a radius of 0.4 inches
Answer:
If the radius of the pastry stamp Petra uses to stamp circles in the dough for the donuts is 4.25 inches, then the diameter is 2 * 4.25 = 8.5 inches. The area of each donut can be calculated using the formula for the area of a circle:
Area of a circle = π * radius^2
So, the area of each donut is:
π * (4.25)^2 = 56.75π square inches (rounded to two decimal places)
If the radius of the pastry stamp Petra uses to stamp out circles for the donut holes is 0.4 inches, then the diameter is 2 * 0.4 = 0.8 inches. The area of each donut hole can be calculated using the same formula:
Area of a circle = π * radius^2
So, the area of each donut hole is:
π * (0.4)^2 = 0.16π square inches (rounded to two decimal places)

a ship steamed 120nm south and 230 nm west. find the distance made good
The distance made good by the ship is approximately 259.5 nautical miles.
What is distance?
Distance is a measurement of how far apart two objects or points are, either numerically or rarely qualitatively. Distance can relate to a physical length in physics or to an estimate based on other factors in everyday language.
To find the distance made good, we need to calculate the total displacement of the ship. This can be found using the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
In this case, the 120 nm southward and 230 nm westward movements of the ship form the legs of a right triangle, and the hypotenuse represents the total displacement. Using the Pythagorean theorem, we get:
Total displacement = √((120²) + (230²)) nm
= √(14400 + 52900) nm
= √(67300) nm
≈ 259.5 nm
Therefore, the distance made good by the ship is approximately 259.5 nautical miles.

The width of a rectangle is the length minus 3 units. The area of the rectangle is 28 square units. What is the length, in units, of the rectangle?
The length of a rectangle cannot be negative, hence the length of the rectangle is 7 units.
Finding area and perimeter of triangleBased on the question given, the width (W) is the length (L) minus 3 units, which can be expressed as:
W = L - 3
The formula for the area (A) of a rectangle is:
A = Length × Width
We are given that the area is 28 square units, so:
A = 28
Now, we can substitute the expressions for width (W) and area (A) into the area formula:
28 = L × (L - 3)
Now, we need to solve this quadratic equation for L. First, expand the equation:
28 = L^2 - 3L
Now, rearrange the equation in standard quadratic form
L^2 - 3L - 28 = 0
To solve this quadratic equation, you can factor it:
(L - 7)(L + 4) = 0
Now, set each factor equal to zero and solve for L:
L - 7 = 0
L = 7
L + 4 = 0
L = -4
Since the length of a rectangle cannot be negative, hence the length of the rectangle is 7 units.

An equation for the function graphed above is [tex]y = \frac{4(x - 1)}{(x + 1)(x - 4)}[/tex].
What is a vertical asymptote?In Mathematics and Geometry, the vertical asymptote of a function simply refers to the value of x (x-value) which makes its denominator equal to zero (0).
By critically observing the graph of this rational function shown above, we can logically deduce that its vertical asymptotes include the following;
x = -1 ⇒ x + 1 = 0.
x = 4 ⇒ x - 4 = 0.
In this context, an equation that represent its denominator is given by the following quadratic function:
Q(x) = (x + 1)(x - 4)
Assuming the leading coefficient of the function P(x) is represented by a;
P(x) = a(x - 1)
By evaluating and solving for the leading coefficient "a" in this function, we have;
f(x) = P(x)/Q(x)
f(x) = a(x - 1)/[(x + 1)(x - 4)]
f(0) = a(0 - 1)/[(0 + 1)(0 - 4)]
f(0) = -a/[(1)(-4)]
f(0) = a/4
Since the y-intercept of this graph is located at (0, 1), the value of the leading coefficient (a) can be calculated as follows;
1 = a/4
1 = a/4
a = 4 × 1
a = 4
By substituting the value of the leading coefficient (a) into the function, we have the following;
f(x) = P(x)/Q(x)
f(x) = y = 4(x - 1)/[(x + 1)(x - 4)]
[tex]f(x) = y = \frac{4(x - 1)}{(x + 1)(x - 4)}[/tex]

Answer:
Answer: C. 40°
Step-by-step explanation:
The shape in the picture is an isosceles triangle. This is determined because two sides share the same length. This will mean that two angles will also share the same measurement, helping us to find our answer.
Step 2: Write an equation
Now that we have identified the type of triangle, we can write an equation to solve. Two angles will be equal to 70, so subtract 70 twice from 180. It will be taken away from 180, since in a triangle the three angles are equal to 180 degrees. Now we can write the equation!
X= 180-70-70
Step 3: Solve for ∠x
The final step will be to solve using the equation we have created before.

What is the fraction?
A fraction is a numerical quantity that represents a part of a whole or a ratio between two quantities. It is expressed as one integer divided by another integer, with a horizontal line separating the two numbers. The number above the line is called the numerator and the number below the line is called the denominator.
To divide a fraction by another fraction, you need to multiply the first fraction by the reciprocal of the second fraction.
First, we need to convert the mixed number to an improper fraction:
1 3/5 = (5*1 + 3)/5 = 8/5
Now we can find the reciprocal of 8/5:
reciprocal of 8/5 = 5/8
So, 3/8 ÷ 1 3/5 can be rewritten as:
3/8 ÷ 8/5 = 3/8 * 5/8
Multiplying the numerators and denominators:
3/8 * 5/8 = (35)/(88) = 15/64
Therefore, 3/8 divided by 1 3/5 is 3/8 ÷ 1 3/5 = 15/64.

What is indirect cost?Indirect costs are expenses that cannot be directly linked to a specific product or service. Instead, they are costs that are incurred for the general operation of a business and are shared among different products or services produced by the business.
In the given question,
To calculate the customer margin on sales to Interstate Trucking, we need to use the activity-based costing system to allocate the indirect costs to the order and then subtract the total costs from the sales revenue. Here are the steps to follow:
Calculate the total indirect costs for the order:
Batch processing cost = Number of batches x Batch processing activity rate
Batch processing cost = 3 x $95 = $285
Order processing cost = Number of orders x Order processing activity rate
Order processing cost = 1 x $285 = $285
Customer service cost = Number of customers x Customer service activity rate
Customer service cost = 1 x $2,624 = $2,624
Total indirect costs = Supporting direct labor cost + Batch processing cost + Order processing cost + Customer service cost
Total indirect costs = Number of direct labor-hours x Supporting direct labor activity rate + Batch processing cost + Order processing cost + Customer service cost
Total indirect costs = 0.7 x 2,200 x $8 + $285 + $285 + $2,624
Total indirect costs = $20,289
Calculate the total costs for the order:
Total costs = Direct materials cost + Direct labor cost + Total indirect costs
Total costs = $110 x 2,200 + $13.70 x 2,200 + $20,289
Total costs = $147,739
Calculate the customer margin on sales:
Customer margin = Sales revenue - Total costs
Customer margin = $141.60 x 2,200 - $147,739
Customer margin = $181,320 - $147,739
Customer margin = $33,581
Therefore, the customer margin on sales to Interstate Trucking for the year is $33,581.

A truck with 38-in.-diameter wheels is traveling at 60 mi/h.
Find the angular speed of the wheels in rad/min: rad/min
How many revolutions per minute do the wheels make?
Answer:
530.7 rpm3334.7 rad/minStep-by-step explanation:
You want the angular speed in RPM and in radians per minute for a truck wheel 38 inches in diameter traveling at 60 mph.
RevolutionsThere are 60 minutes in an hour, so a speed of 60 mi/h is a speed of ...
[tex]\dfrac{60\text{ mi}}{1\text{ h}}\times\dfrac{1\text{ h}}{60\text{ min}}\times\dfrac{5280\text{ ft}}{1\text{ mi}}=5280\text{ ft/min}[/tex]
The distance traveled for 1 revolution of the wheel is equal to its circumference:
C = πd
C = π(38 in)/(12 in/ft) = (19/6)π ft ≈ 9.948 ft
Then the number of revolutions in 5280 ft is ...
(5280 ft/min)/(9.948 ft/rev) ≈ 530.7 rev/min
The wheels make about 530.7 revolutions per minute.
RadiansEach revolution is an angle of 2π radians, so the angular speed is ...
ω = 530.7 rev/min × 2π rad/rev
ω = 3334.7 rad/min

A company makes paper labels for paint cans. As shown below, each can is in the shape of a cylinder with a height of 6in and a diameter of 6in. The paper label is wrapped around the can and covers only the side of the can (not the top or bottom). If the company has a total of 5312.88in2 of paper available, how many labels can be made? Use 3.14 for π, and do not round your answer.
Answer:
Answer: 4,772.8 cm2
Step-by-step explanation:
The company will need 3,583.2 square inches of paper to make 15 labels.
What is cylinder?
Traditionally, a cylinder was a three-dimensional solid, one of the most fundamental curvilinear geometric shapes. It is a prism with a circle as its base in elementary geometry.
The formula for circumference is:
Circumference = π × diameter
Circumference = 3.14 × 8in
Circumference = 25.12in
So the label will need to be 25.12 inches long.
The height of the label will be the same as the height of the can, which is 9 inches.
To find the total area of the paper needed for 15 labels, we need to multiply the length of each label by its height and then multiply that by the number of labels:
Total area = length × height × number of labels
Total area = 25.12in × 9in × 15
Total area = 3,583.2 square inches
Thus, the answer is 3,583.2 square inches.

Bao has 39 m of fencing to build a three-sided fence around a rectangular plot of land that sits on a riverbank. (The fourth side of the enclosure would be the river.) The area of the land is 169 square meters. List each set of possible dimensions (length and width) of the field.
The possible dimensions of the rectangular plot are 13 m by 13 m (a square) or 26 m by 6.5 m.
What is perimeter?Perimeter is the total distance around the edge of a two-dimensional shape, such as a polygon or a circle. It is calculated by adding up the lengths of all the sides of the shape. The perimeter is a measure of the distance that must be covered to go around the shape, and is typically expressed in units of length, such as meters or feet.
Let the length of the rectangular plot be L and the width be W.
We know that the perimeter of the rectangular plot is equal to the sum of the lengths of the three sides of the fence:
2L + W = 39
Also, the area of the plot is LW = 169.
From the second equation, we can solve for L or W in terms of the other variable:
L = 169/W or W = 169/L.
Substitute these expressions into the first equation:
2(169/W) + W = 39
Simplify and rearrange:
2(169) + W² = 39W
W² - 39W + 338 = 0
Solve for W using the quadratic formula:
W = (39 ± √(39² - 4(1)(338))) / 2
W = (39 ± 13) / 2
W = 26 or 13.
If W = 26, then L = (39 - 2W)/2 = -6, which is not possible. So, we can discard this solution.
If W = 13, then L = (39 - 2W)/2 = 13.
Therefore, the possible dimensions of the rectangular plot are 13 m by 13 m (a square) or 26 m by 6.5 m.

What is the Law of Sines?
The Law of Sines is a mathematical formula used to relate the side lengths and angles of any triangle. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle.
a/sin(A) = b/sin(B) = c/sin(C)
To find the length of side z in triangle XYZ, we can use the Law of Sines, which states:
a/sin(A) = b/sin(B) = c/sin(C)
where a, b, and c are the lengths of the sides of a triangle, and A, B, and C are the opposite angles.
In this case, we know the length of side x, and the measures of angles Y and Z.
We want to find the length of side z. So, we can use the Law of Sines as follows:
z/sin(180° - 141° - 25°) = 830/sin(141°)
z/sin(14°) = 830/sin(141°)
Cross-multiplying:
z = (830*sin(14°))/sin(141°)
z ≈ 261.8 cm
Therefore, the length of side z to the nearest tenth of a centimeter is approximately 261.8 cm.
