Fill out the tables for each scenario and answer the question that follows. Use $7.25 as the minimum wage and remember that empl

Answer:

see below for the table values
US labor cost: $115275 per year

Step-by-step explanation:

The labor charge is for (6 days/week). In Mongolia, the charge per laborer is then ...

(6 days/week)($1.10/day) = $6.60/week

The three laborers working 50 weeks/year will have a labor cost of ...

(3 laborers)($6.60/week/laborer)(50 weeks/year) = $990/year

In the US, the labor charge per person per week is ...

(14 hr/day)(6 day/week) = 84 hr/week

That's 40 hours of straight pay and 44 hours of overtime pay, or ...

7.25(40 +1.5(44)) = 7.25(106) = 768.50

For 150 person-weeks per year, the total US labor charge is ...

($768.50/person/week)(3 persons)(50 weeks/year) = $115,275/year

The materials cost for a year is ...

($50/rug)(12 rugs/year) = $600/year

The revenue is ...

($2000/rug)(12 rugs/year) = $24,000/year

Profit is the difference between revenue and the total of costs:

profit = $24,000 -($990 +600 +10000) = $12410 . . . made in Mongolia

So, the table gets filled as follows:

(labor, material, fixed cost, revenue, profit)

Mongolian-made

($990, $600, $10000, $24000, $12410)

US-made

($115275, $600, $10000, $24000, -$101,875)

The US labor cost would be $115,275.

Comment

For the given selling price, the break-even labor cost is about $1.06 per hour (on average). At US labor rates, the break-even selling price is about $10,490 per rug.

Explain why each of the following integrals is improper. (a) 4 x x − 3 dx 3 Since the integral has an infinite interval of integ

erma4kov [3.2K]

Answer:

Since the integral has an infinite discontinuity, it is a Type 2 improper integral

Since the integral has an infinite interval of integration, it is a Type 1 improper integral

Since the integral has an infinite discontinuity, it is a Type 2 improper integral

Step-by-step explanation:

Considering a

$\int\limits^4_3 {\frac{x}{x- 3} } \, dx$

Looking at this we that at x = 3 this integral will be infinitely discontinuous

Considering b

$\int\limits^{\infty}_0 {\frac{1}{1 + x^3} } \, dx$

Looking at this integral we see that the interval is between $0 \ and \ \infty$ which means that the integral has an infinite interval of integration , hence it is a Type 1 improper integral

Considering c

$\int\limits^{\infty}_{- \infty} {x^2 e^{-x^2}} \, dx$

Looking at this integral we see that the interval is between $-\infty \ and \ \infty$ which means that the integral has an infinite interval of integration , hence it is a Type 1 improper integral

Considering d

$\int\limits^{\frac{\pi}{4} }_0 {cot (x)} \, dx$

Looking at the integral we see that at x = 0 cot (0) will be infinity hence the integral has an infinite discontinuity , so it is a Type 2 improper integral

27? i cant figure out her mistake can anyone help ?

expeople1 [14]

The mess up occurs in one of the first things she says. She first claims that 7^2 +25^2 = 24^2
Wait a minute... slow your roll there.
25 is the hypotenuse, or the longest side of the triangle AND opposite the right angle (but we aren't supposed to know that yet).
The Pythagorean Theorem holds that a^2 + b^2 = c^2, where a & b are the legs of the triangle & c is the hypotenuse. So, she got the formatting correctly, but she switched 24 & 25.
Hope this helps!

What is 6 divided by 7/9

Hunter-Best [27]

Answer:

54/7

Step-by-step explanation:

Use the KCF method - Keep, Change, Flip
6 divided by 7/9 is just 6/1 divided by 7/9
You can keep 6/1 as the way it is
Next, you change the sign from division to multiplication
Lastly, you flip 7/9 to 9/7
It will now change from 6 divided by 7/9 to 6/1 x 9/7
You now multiple 9 x 6 which is 54 and divide by 7
You cannot simplify further so the answer is 54/7
