Answer:
They should operate Mine 1 for 1 hour and Mine 2 for 3 hours to meet the contractual obligations and minimize cost.
Explanation:
The formulation of the linear programming is:
Objective function:
Restrictions:
- High-grade ore: 
- Medium-grade ore: 
- Low-grade ore: 
- No negative hours: 
We start graphing the restrictions in a M1-M2 plane.
In the figure attached, we have the feasible region, where all the restrictions are validated, and the four points of intersection of 2 restrictions.
In one of this four points lies the minimum cost.
Graphically, we can graph the cost function over this feasible region, with different cost levels. When the line cost intersects one of the four points with the lowest level of cost, this is the optimum combination.
(NOTE: it is best to start with a low guessing of the cost and going up until it reaches one point in the feasible region).
The solution is for the point (M1=1, M2=3), with a cost of C=$680.
The cost function graph is attached.
Answer: Option (B) is correct.
Explanation:
Given that,
Total population of group = 28.19 million
Employed = 11.73 million
Unemployed = 1.04 million
Total labor force = Employed + Unemployed
= 11.73 million + 1.04 million
= 12.77 million
Labor-force participation rate = 
= 
= 45.29%
= 45.3%
Unemployment rate = 
= 
= 8.14%
Answer:
the answer is insurance, jobs, rentals on edgy
The correct option is ALL OF THE ABOVE.
The start up cost of a business refers to those costs that are incurred before the business start operation. Such costs include: rent, legal fees, insurance, start up equipment, etc,
Assimilation efficiency quantifies the ratio between the organism's used energy for growth and production of new cells and tissues, and others.
We let x be the amount of substance assimilated.
AE = x / 10,000
From the given, AE is equal to 0.5. Substituting,
0.5 = x/10,000
x = 5,000
Production efficiency on the other hand is the ratio of the amount of substance used for production compared to the assimilation. Mathematically,
PE = 2,000 / x = 2,000/5,000
PE = 0.4
This is equivalent to a percentage of 40%.
