Answer:

Step-by-step explanation:

Alright, lets get started.

The given expression as :

$\frac{3}{7}r + \frac{5}{8}s$

r is given as 14 and s is given as 8

Plugging the value of r and s in given expression.

$\frac{3}{7}(14) + \frac{5}{8}(8)$

$3*2 + 5$

$6+5$

$11$

Hence the answer is 11 : Answer

Hope it will help :)

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.

Answer: 2x + 5y = -5

Step-by-step explanation:

Two lines are said to be parallel if they have the same slope.

The equation of the line given :

2x + 5y = 10

To find the slope , we will write it in the form y = mx + c , where m is the slope and c is the y - intercept.

2x + 5y = 10

5y = -2x + 10

y = -2/5x + 10/5

y = -2/5x + 2

This means that the slope is -2/5 ,the line that is parallel to this line will also have a slope of -2/5.

using the formula:

$y-y_{1}$ = m ( $x-x_{1}$ ) to find the equation of the line , we have

y - 1 = -2/5(x -{-5})

y - 1 = -2/5 ( x + 5 )

5y - 5 = -2 ( x + 5 )

5y - 5 = -2x - 10

5y + 2x = -10 + 5

therefore :

2x + 5y = -5 is the equation of the line that is parallel to 2x + 5y = 10
