The employer would need to pay $19.13 in payroll taxes for this employee.

Payroll tax is a tax that employers are required to deduct from their employee's wages and pay to the government on their behalf.

It is a tax on the wages or salaries that employees earn and is used to fund various government programs, such as Social Security, Medicare, and unemployment insurance.

We have,

The amount an employer needs to pay for payroll taxes depends on several factors.

The employee's gross wages

The type of payroll taxes.

The tax rates are in effect.

Now,

The two primary types of payroll taxes that employers are responsible for are:

Social Security tax:

This tax funds the Social Security program and is calculated as a percentage of the employee's gross wages, up to a certain limit.

In 2023, the Social Security tax rate is 6.2% for both employers and employees, and the wage base limit is $147,000.

Medicare tax:

This tax funds the Medicare program and is calculated as a percentage of the employee's gross wages, with no limit.

In 2023, the Medicare tax rate is 1.45% for both employers and employees.

Assuming the employee owes $250 for Social Security and Medicare taxes combined, and the employer is responsible for paying the same percentage rate as the employee,

The employer would need to pay an additional $250 in payroll taxes.

i.e

Social Security tax.

= $250 x 6.2%

= 250 x 6.2/100

= $15.50

Medicare tax.

= $250 x 1.45%

= 250 x 1.45/100

= $3.63

Total payroll taxes owed by the employer.

= $15.50 + $3.63

= $19.13

Therefore,

The employer would need to pay $19.13 in payroll taxes for this employee.

The scenario describes calculating the multiple of growth in the US national debt from 1970 to 1990 using scientific notation, showing that the debt was nearly 9 times larger in 1990 than in 1970

Let's create a scenario involving the United States' national debt from two different decades using multiplication in scientific notation. Imagine the government wanted to compare the debt from 1970 to that of 1990 to analyze the growth. The debt in 1970 was approximately $370.9 billion, and in 1990, about $3,233.3 billion. To find out how many times larger the debt was in 1990 compared to 1970, we'd convert these numbers into scientific notation and divide the 1990 figure by the 1970 figure.

In scientific notation, the 1970 debt is 3.709 x 1011 dollars, and the 1990 debt is 3.2333 x 1012 dollars. To perform the division, we have (3.2333 x 1012) / (3.709 x 1011) which gives us approximately 8.71. This means the national debt in 1990 was nearly 9 times larger than it was in 1970

The composite function that converts temperatures from degrees Kelvin to degrees Fahrenheit is:

K to F = 9/5 * K - 241.15

The image shows a question about how to convert temperatures from degrees Celsius to degrees Fahrenheit using composite functions. The question provides two functions:

[tex]$F(x) = \frac{9}{5}x + 32$[/tex] converts from degrees Celsius to degrees Fahrenheit

[tex]$C(x) = x - 273.15$[/tex]converts from degrees Kelvin to degrees Celsius

We are asked to find the composite function [tex]$C \circ F$[/tex] that converts from degrees Kelvin to degrees Fahrenheit.

To find the composite function, we simply substitute the output of the first function, [tex]$F(x)$[/tex], into the input of the second function, [tex]$C(x)$[/tex]. This gives us:

[tex]```(C \circ F)(x) = C(F(x)) = F(x) - 273.15 = \frac{9}{5}x - 241.15```[/tex]

Therefore, the composite function that can be used to convert temperatures from degrees Kelvin to degrees Fahrenheit is:

[tex]```(C \circ F)(x) = \frac{9}{5}x - 241.15```[/tex]

A composite function is a function that is created by composing two or more other functions. In other words, it is a function that takes the output of one function as the input to another function. Composite functions are often used to solve complex problems that cannot be solved using a single function.

For example, the composite function that we found above,[tex]$(C \circ F)(x)$[/tex], can be used to convert temperatures from degrees Kelvin to degrees Fahrenheit. This is a useful function for scientists and engineers who work with temperatures in different units.

Another example of a composite function is the product rule in calculus. The product rule states that the derivative of the product of two functions [tex]$u(x)$[/tex]and [tex]$v(x)$[/tex] is equal to the sum of the product of the derivatives of [tex]$u$[/tex] and [tex]$v$[/tex] and the product of [tex]$u$[/tex] and the derivative of [tex]$v$[/tex]. This can be expressed mathematically as follows:

[tex]```\frac{d}{dx}[u(x)v(x)] = u'(x)v(x) + u(x)v'(x)```[/tex]

The product rule is a composite function because it takes the output of two functions, [tex]$u$[/tex] and [tex]$v$[/tex], and their derivatives,[tex]$u'$[/tex] and [tex]$v'$[/tex], and produces a new function, [tex]$\frac{d}{dx}[u(x)v(x)]$[/tex].

Composite functions are a powerful tool that can be used to solve a wide variety of problems in mathematics, science, and engineering.

Answer:

C. 1.9090%

Step-by-step explanation:

We have been given that the APR of a savings account is 1.9% and interest is compounded semiannually. We are asked to find the APY of the account.

To solve our given problem, we will use APY formula.

[tex]APY=(1+\frac{r}{n})^n-1[/tex], where,

r = Annual interest rate in decimal form,

n = Number of times interest is compounded per year.

Let us convert our given rate in decimal form.

[tex]1.9\%=\frac{1.9}{100}=0.019[/tex]

Upon substituting [tex]r=0.019[/tex] and [tex]n=2[/tex] in APY formula we will get,

[tex]APY=(1+\frac{0.019}{2})^2-1[/tex]

[tex]APY=(1+0.0095)^2-1[/tex]

[tex]APY=(1.0095)^2-1[/tex]

[tex]APY=1.01909025-1[/tex]

[tex]APY=0.01909025[/tex]

Since APY is in decimal form, so we will multiply APY by 100 to get as percentage.

[tex]APY=0.01909025\times 100[/tex]

[tex]APY=1.909025\%\approx 1.9090\%[/tex]

Therefore, the the approximate APY of the account 1.9090% and option C is the correct choice.

Final answer:

68% of the total combined amount of paint is used for the job, calculated by using 20% of the blue paint and 80% of the crimson paint from the initial amounts of 2 liters and 8 liters, respectively.

Explanation:

To calculate the percentage of the total combined amount of paint used during the job, we first identify the amount of blue and crimson paint used separately. From the question we know that there were initially 2 liters of blue paint and 8 liters of crimson paint.

Now, we compute the total paint used and the initial total paint:

To find the percentage of the total paint used, we divide the total paint used by the initial total paint and multiply by 100:

Percentage used = (Total paint used / Initial total paint) × 100

Percentage used = (6.8 liters / 10 liters) × 100 = 68%

Therefore, 68% of the total combined amount of paint is used for the job.

Answer:

Option 3. 1/14

Step-by-step explanation:

The bag held some coins that are

pennies = 10

nickels = 6

dimes = 5

total coins = 10 + 6 + 5 = 21 coins

You drew 2 coins without replacement,

so the probability that first draw will be nickel = [tex]P_{1}[/tex] = 6/21 = 2/7

Second draw will be a dime  = [tex]P_{2}[/tex] = 5/20 = 1/4

P = [tex]\frac{2}{7}[/tex] × [tex]\frac{1}{4}[/tex] = 2/28 = 1/14

Option 3. 1/14 would be the answer.

Final answer:

The probability of withdrawing a nickel and then a dime from the bag without replacement is 1/14, calculated by multiplying the independent probabilities of drawing each coin in sequence (6/21 for the nickel and 5/20 for the dime).

Explanation:

The student has asked for the probability of withdrawing first a nickel and then a dime from a bag containing ten pennies, six nickels, and five dimes, without replacement. To solve this, we calculate the probability of each event independently and then multiply these probabilities, since the events are dependent.

First, the probability of drawing a nickel: There are six nickels and a total of 21 coins, so the probability is 6/21. After drawing a nickel, there are five dimes left out of 20 coins total, thus the second probability is 5/20. Multiplying these together gives us:

(6/21) * (5/20) = 30/420 = 1/14

So, the probability of drawing a nickel and then a dime without replacement from this bag of coins is 1/14.
