Answer:
the lowest operating cost is achieved when mine 1 is operated for 0 hours and mine 2 is operated for 2 hours.
Explanation:
Mining hours of mine 1: M1
mining hours of mine 2: M2
Objective function: Minimize operating cost < 200M1 + 160 M2
Explicit constraints:
6M1 + 2M2 ≥ 12
2M1+ 2M2≥ 8
4M1+ 12M2 ≥ 24
Implicit constraints:
M1> 0
M2>0
See the attachment for feasible region
The coordinates of feasible region are (0,0), (2,0),(0,2),(1.5,1.5)
To maximize cost substitute each of these coordinates in objective function
for(0,0)
cost=0 (neglect this cost since M1>0 and M2 >0)
for(2,0)
cost= 320
for (0,2)
cost= 400
for (1.5,1.5)
cost= 540
the lowest operating cost is achieved when mine 1 is operated for 0 hours and mine 2 is operated for 2 hours
<span>It is false that job hidden in the job market can be discovered through advertisement. As matter of fact, they aren't even advertised. You cant just go to a job post website and get them, if it was then they aren't hidden. There are multiple ways that prove how hard it is to find these jobs. One is that you have to network. Join website like linkedin and you'll be able to connect professionally with others. Talk to people who are also trying to find a job, they are always eager to show you what they found to help someone out in need. Even join the IRA! Most people that are apart of the IRA are able to get hidden jobs before anyone else. As a personal experience I believe these to be true. When I quit my job because of the employees and my medical issue is difficult to find a job. Most job wants you to have experience already that takes years to earn, especially if you have no degree. Though I am not trying to knocked down website like snagajob, indeed, and zip recruiter etc, they aren't that helpful. rarely you will get a call back and your resume ends up not being looked at or in the trash. The way I found my first job was actually through someone else. It was hidden on a website which they guide me to and I was quickly hired.</span>
Answer:
increase by $11,000
Explanation:
The computation of net operating income is shown below:-
Revenue = Sales per unit × Sales price per unit
= 3,000 × $70
= $210,000
Less variable costs = Sales per unit × Variable cost per unit
= 3,000 × $50
= $150,000
Fixed costs = $25,000
Net income = Revenue - Less variable costs - Fixed costs
= $210,000 - $150,000 - $25,000
= $35,000
Contribution margin per units = $70 - $50
= $20
Increase by 10%, it will be
$20 × (1 + 0.1)
= $22
If it decrease by 20%
= $25,000 × (1 - 0.20)
= $20,000
Net income = $3,000 × 22 - 20,000
= 46,000
So it was 35,000, with the changes it is 46,000. That increase by $11,000
Answer:
d.Cost, residual value, and service life
Explanation:
The depreciation of an asset is the systematic allocation of cost for the use of the asset over its useful life.
Depreciation is usually computed using the formula below
Depreciation = (cost - salvage value)/useful life
The difference between the cost and salvage value is the depreciation base of the asset over its entire useful life.
As such, the right option is d.Cost, residual value, and service life
The reason why hosa require students to joint through local chapter instead of joining as individuals is :
Hosa activities are so closely connected with the school curriculum,
And this curriculum usually more compatible if it's carried out in groups.
