The answer is 6 inches

Answer:B

Step-by-step explanation:

After 3 minutes you both have knitted the same amount of rows.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, You knit 8 rows each minute and have already knitted 10 rows.

Your friend knits 5 rows each minute and has already knitted 19 rows.

Assuming t is the time when will you both have knitted the same amount of rows,

8t + 10 = 5t + 19.

8t - 5t = 19 - 10.

3t = 9.

t = 3 minutes.

The time at which her lesson start is 9:30 am.

More people to do a task means less time it will take.

Less people to do a task means more time it will take.

Thus, they are inversely related.

If x men take y time for a work,

We can define a constant as "Manpower" needed for doing that specific work.

Let we define:

Manpower needed for a work = y + y + y + .. + y = Time per man × count of men

Manpower needed for a work = xy

We are given that;

Time= 1 hour 20 minutes

Now,

To find the time when Sierra’s lesson started, you need to subtract the duration of her lesson from the time when she finished. You can do this by subtracting the minutes and then the hours.

First, subtract 20 minutes from 10:50 am. To do this, you can take away 10 minutes to get 10:40 am and then take away another 10 minutes to get 10:30 am.

Next, subtract 1 hour from 10:30 am. To do this, you can take away 60 minutes or simply reduce the hour by 1. Either way, you get 9:30 am.

Therefore, by work and time the answer will be 9:30 am.

Final answer:

The proportion of data more than 2.0 standard deviations away from the mean in a normal distribution is less than 5%, consisting of 2.5% in the upper tail and 2.5% in the lower tail.

Explanation:

The proportion of values more than 2.0 standard deviations from the mean in a normal distribution is less than 5% because according to the empirical rule, 95% of the data falls within 2 standard deviations of the mean. Therefore, if you are looking at a normal distribution and you want to know the proportion of data that lies beyond 2 standard deviations from the mean, you would subtract 95% from 100%, which is 5%. This is then split between both tails of the distribution, so you have 2.5% in the upper tail and 2.5% in the lower tail, for a total of 5% more than 2 standard deviations away from the mean.

Final answer:

The total Social Security tax for Ty's earnings this week, given his total earnings are now $110,600, is $155.00. This calculation considers the Social Security tax rate of 6.2% up to the income threshold of $110,100. Thus, option B is correct.

Explanation:

The question involves calculating the Social Security tax for Ty's earnings this week. With cumulative earnings to date at $107,600 and an additional $3,000 this week, Ty's total earnings for the year are now $110,600.

Since the Social Security tax rate is 6.2% and applies only up to an income of $110,100, we will only apply the tax rate to the $110,100 threshold, not the full $110,600. The week's Social Security tax is then:

0.062 × $110,100 = $6,826.20 (for the entire year so far)

Since we only need to find out the tax for this week's earnings, we need to calculate the tax that was already paid on the first $107,600:

0.062 × $107,600 = $6,671.20

The additional Social Security tax for this week is the difference between the two:

$6,826.20 - $6,671.20 = $155.00

Therefore, the total Social Security tax for this week is $155.00, which corresponds to option B.

The total amount of Social Security tax for Ty this week is $155.00. Hence, the correct option is B.

To calculate the total amount of Social Security tax for Ty this week, we must apply the 6.2% rate to his weekly pay of $3,000. However, since his cumulative earnings to date are $107,600 and the Social Security tax applies only up to $110,100, we need to determine how much of his $3,000 weekly salary is subject to this tax.

To find this, we subtract his current earnings from the maximum amount that is subject to Social Security tax: $110,100 - $107,600 = $2,500. Only $2,500 of Ty's $3,000 salary is taxable for Social Security purposes since he has reached the threshold beyond which Social Security tax is not levied on additional income.

Therefore, this week's Social Security tax is 6.2% of $2,500, which equals $155.00. As the rate for Medicare does not cap, the full $3,000 is subject to the Medicare tax at a rate of 1.45%, leading to a Medicare tax amount of $43.50. However, as the question only asks for the Social Security tax, the answer is B. $155.00.

Answer:

The correct answer is: Option: D

D. Maximum: 35°   ;  minimum: −15°  ; Period: 4 hours

Step-by-step explanation:

We are given a function f(t) as:

          [tex]f(t)=25\sin (\dfrac{\pi}{2}t)+10[/tex]

We know that the maximum value of the function is obtained when the sine function is maximum.

i.e. when sine takes the value=1

and the minimum value of the function is obtained when the sine function is minimum.

i.e. when sine takes the value= -1

Hence, the minimum value of the function is:

-25+10= -15

and the maximum value of the function is:

25+10=35

Also the period of the function of the type:

[tex]f(x)=a\sin(bx)+c[/tex]

is:

[tex]Period=\dfrac{2\pi}{b}[/tex]

Hence, here we have: b=π/2

Hence, period is:

[tex]Period=\dfrac{2\pi}{\dfrac{\pi}{2}}\\\\\\Period=4[/tex]

         Hence, option: D is the correct answer.

To find the amount of interest earned on a bank account after 4 years, use the compound interest formula. After plugging in the values, the account earns approximately $162.89 in interest.

To calculate the amount of interest earned on a bank account after 4 years, we need to use the formula for compound interest: A = P(1 + r/n)^(nt) - P. In this case, the initial deposit (P) is $3000, the annual interest rate (r) is 1.25%, compounded semi-annually (n = 2), and the time period (t) is 4 years. Plugging in these values, we get:

A = 3000(1 + 0.0125/2)^(2*4) - 3000

Solving this equation, we find that the account earns approximately $162.89 in interest after 4 years.

Final answer:

The lowest common denominator of the fractions 5/(n-2) and[tex](n+2)/(n^2-4)[/tex] is[tex]n^2 - 4,[/tex] which is the factored form of the denominator of the second fraction.

Explanation:

The question asks to find the lowest common denominator (LCD) of two fractions: 5/(n-2) and (n+2)/[tex]n^2 - 4,[/tex]. To do this, we need to factor each denominator, if possible, and then determine the LCD. The second denominator can be factored into (n+2)(n-2) since it is a difference of squares. For the LCD, we need each factor present at least as many times as it occurs in any one of the denominators. The first fraction is already missing the (n+2) factor, so we multiply the numerator and the denominator of this fraction by (n+2) to have an equivalent fraction with the common denominator.

The common denominator then is (n+2)(n-2), equivalent to[tex]n^2 - 4,[/tex] So the LCD of the two fractions is[tex]n^2 - 4.[/tex] We can use this denominator to combine fractions or compare them. No further steps are necessary because the second fraction already has the LCD. Therefore, the LCD for both fractions is [tex]n^2 - 4.[/tex]

Final answer:

The total number of employees working is 54. According to company policy requiring 1 supervisor for every 8 employees, 7 supervisors are needed to comply with this policy.

Explanation:

To find how many supervisors are required, we first need to know the total number of employees working. Since there are 3 teams of 18 employees, the total number of employees is 3 teams * 18 employees per team = 54 employees. Company policy requires 1 supervisor for every 8 employees. Therefore, we divide the total number of employees by the supervisor to employee ratio: 54 employees / 8 employees per supervisor = 6.75. Since we cannot have a fraction of a supervisor, we round up to the next whole number, making it 7 supervisors needed in total.

So, the supervisor would say: "We need 7 supervisors working tonight so we should be OK."
