Tom and Keira will owe $182,002 in federal income tax for 2022.

To calculate the federal income tax that Tom and Keira will owe in 2022, we need to first determine their taxable income.

Assuming that Tom and Keira have no dependents, their standard deduction for 2022 is $25,900. Therefore, their taxable income is:

Taxable income = Combined income - Standard deduction

Taxable income = $208,264 - $25,900

Taxable income = $182,364

To determine their federal income tax, we need to use the tax brackets and rates for 2022. According to the IRS, for married filing jointly status, the tax rates for 2022 are as follows:

10% on taxable income up to $21,450

12% on taxable income over $21,450 up to $87,850

22% on taxable income over $87,850 up to $183,250

24% on taxable income over $183,250 up to $351,600

32% on taxable income over $351,600 up to $431,200

35% on taxable income over $431,200 up to $666,450

37% on taxable income over $666,450

To calculate the federal income tax owed, we need to apply the appropriate tax rates to the corresponding income brackets. In this case, the taxable income falls within the following brackets:

$21,450 at 10% = $2,145

($87,850 - $21,450) at 12% = $7,026

($183,250 - $87,850) at 22% = $24,457

($351,600 - $183,250) at 24% = $42,336

($431,200 - $351,600) at 32% = $25,280

($666,450 - $431,200) at 35% = $80,758

($182,364 - $666,450) at 37% = $0

Therefore, the total federal income tax owed for 2022 is:

Total federal income tax = $2,145 + $7,026 + $24,457 + $42,336 + $25,280 + $80,758 + $0

Total federal income tax = $182,002

Therefore, Tom and Keira will owe $182,002 in federal income tax for 2022.

The value of x and y for the given set of triangle is x = 1.8022 cm and y = 0.9054 cm.

In geometry, a triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry and has many properties and applications in mathematics and other fields. The sum of the interior angles of a triangle is always 180 degrees, and the area of a triangle can be calculated using various formulas depending on the given information, such as the base and height, the lengths of the sides, or the angles. Triangles can also be classified based on the length of their sides and the measure of their angles, such as equilateral, isosceles, scalene, acute, right, and obtuse triangles. Triangles are used in many fields, including engineering, architecture, physics, and computer graphics, among others.

Here,

We can use the Pythagorean theorem and the fact that the base is divided by the altitude in a 3:1 ratio to find x and y.

Let's call the length of the altitude h, and the length of the base b.

Since the base is divided by the altitude in a 3:1 ratio, we have:

b/h = 3/1

b = 3h

We know that the side adjacent to the angle is 6 cm, and that the height of the altitude is x cm. Therefore, we have:

cos(θ) = adjacent/hypotenuse

cos(θ) = 6/b

cos(θ) = 6/(3h)

cos(θ) = 2/h

We also know that the length of the altitude is h, and that the length of the base is 3h. Therefore, we have:

h² + (3h)² = (6 cm)²

Simplifying this equation gives:

h² + 9h² = 36

10h² = 36

h² = 3.6

h = √(3.6)

h = 1.8974 cm (rounded to four decimal places)

Now we can use the equation we derived earlier for cos(theta) to find y:

cos(θ) = 2/h

cos(θ) = 2/1.8974

cos(θ) = 1.0546 (rounded to four decimal places)

y = hypotenuse * sin(θ)

y = 6 * sin(cos⁻¹(1.0546))

y = 0.9054 cm (rounded to four decimal places)

Therefore, x = √(h² - y²)

= √(3.6 - 0.9054²)

= 1.8022 cm (rounded to four decimal places)

So, x = 1.8022 cm and y = 0.9054 cm.

Required equation represents

3 × 3/5 as a multiple of a unit fraction is 9 x 1/5.

To multiply a whole number by a fraction, you can convert the whole number to a fraction with a denominator of 1. So, 3 can be written as 3/1.

Now, to multiply 3/1 by 3/5, you can multiply the numerators (top numbers) together and the denominators (bottom numbers) together separately:

3/1 × 3/5 = (3 × 3) / (1 × 5)

Simplifying the numerator and denominator gives 9/5

To write this as a multiple of a unit fraction (a fraction with a numerator of 1), you need to rewrite 5 as a product of 1 and another number (in other words, find a denominator that is a multiple of 5):

5 = 1 × 5

Then, you can write 9/5 as:

9/5 = (9/1) × (1/5)

So, the equation that represents 3 × 3/5 as a multiple of a unit fraction is:

Answer:
1. D. -1/81
2. D. 1
3. A. -1/5
4. A. -1/27ab^6

To find the simplified form of each expression, we can use the rule of exponents and the distributive property.
For the first expression, we can use the rule of exponents that states that x^-n = 1/x^n. Therefore, (-3)^-4 = 1/(-3)^4 = 1/(-81) = -1/81.
For the second expression, we can use the rule of exponents that states that any number raised to the power of 0 is equal to 1. Therefore, (-7.4)^0 = 1.
For the third expression, we can use the rule of exponents that states that x^-n = 1/x^n. Therefore, -(5)^-1 = 1/-(5)^1 = 1/-5 = -1/5.
For the fourth expression, we can use the distributive property to rewrite -(3ab^2)^-3 as -(3^-3) * (ab^2)^-3. We can then use the rule of exponents that states that x^-n = 1/x^n to find that -(3^-3) * (ab^2)^-3 = -1/(3^3) * 1/(ab^2)^3 = -1/27ab^6.

B. The advertised sale price of the shoes that day at the store, before sales tax is $42.50

A. We can find the total price Angela paid in the following way:

For the sunglasses:

6% of $15 = 0.06 x $15 = $0.90

Tax paid for sunglasses = $0.90.

For the sweatshirt:

6% of $25 = 0.06 x $25 = $1.50.

Tax paid for sweatshirt = $1.50.

So, we can see here that:

Total price = price of sunglasses + price of sweatshirt + sales tax on both items

Total price = $15 + $25 + $0.90 + $1.50

Total price = $42.40

B. We can find the discount on the shoes as follows:

Discount = 15% of $50 = 0.15 x $50 = $7.50

Therefore, the discounted price of the shoes is:

Discounted Price = Original Price - Discount = $50 - $7.50 = $42.50

Thus, the advertised sale price of the shoes that day at the store, before sales tax = $42.50.

ABC  Company has sales forecasts of the following .cash receipts for March are $45,820

What is calculation?.

The calculation involves applying the given collection percentages to the sales forecasts and then subtracting the uncollectible percentage from the total amount of sales. The calculation steps are as follows:

Calculate the amount of January sales that will be collected in March: $40,000 x 0.20 = $8,000

Calculate the amount of February sales that will be collected in March: $65,000 x 0.50 = $32,500

Calculate the amount of March sales that will be collected in March: $52,850 x 0.25 = $13,212.50

Add up the three amounts of collections: $8,000 + $32,500 + $13,212.50 = $53,712.50

Calculate the uncollectible amount: $157,850 x 0.05 = $7,892.50

Subtract the uncollectible amount from the total collections: $53,712.50 - $7,892.50 = $45,820

Therefore, the calculation shows that the cash receipts for March are $45,820.

To calculate the cash receipts for March, we need to first determine how much of the January, February, and March sales will be collected in March.

For January sales, 20% will be collected in March, which is $40,000 x 0.20 = $8,000.

For February sales, 50% will be collected in March, which is $65,000 x 0.50 = $32,500.

For March sales, 25% will be collected in March, which is $52,850 x 0.25 = $13,212.50.

To account for the 5% uncollectible, we need to subtract 5% of the total amount of sales from the total cash receipts. The total sales are $40,000 + $65,000 + $52,850 = $157,850. So, 5% of $157,850 is $7,892.50.

Therefore, the total cash receipts for March are:

$8,000 + $32,500 + $13,212.50 - $7,892.50 = $45,820

Furthermore, the sum of the angles in a triangle is equal to 180. This ultimately implies that, we would sum up all of the angles as follows;

a + c + b = 180°

53 + 58 + b = 180°

b = 180° - 111

b = 69°

In Mathematics and Geometry, the law of sine is modeled or represented by this mathematical equation:

[tex]\frac{sinA}{a} =\frac{sinB}{b} =\frac{sinC}{c}[/tex]

sin69/b = sin53/10

b = 10sin69/sin53

b = 11.690 units.

Answer:

When Jordan Reeves was 10 years old, she designed a toy especially for kids who had only one hand, like her. Later, she thought that other kids with physical differences might want to make something familiar. This idea motivated Jordan to start an organization where kids could get creative. The organization's experts conducted design workshops, and the kids who took part benefited in many ways. For instance, the kids learned about the design process, which could help them prepare for jobs later on.
