Answer: Option A
Explanation: In simple words, perfect competition refers to market structure in which there are large number of participants each operating at small level.
The prices of commodities in such markets are determined by the forces of demand and supply as no individual participant is able to influence the price on his or her own.
Thus, the statement depicting Jill not able to decrease price even after increase ins supply depicts perfect completion.
Answer: The opportunity cost is the most desirable trade-off.
Explanation: Trade-offs refer to the choosing decisions that an individual faces when choosing between two-goods or making any other economic decision. For instance, a graduate may face a trade-off between choosing a job or starting up his own business.
While, opportunity cost is simply the cost of the lost alternative. For example, if the graduate chooses to start a business then his opportunity cost is the salary foregone from going for a job.
Thus, when deciding on which option to choose (trade-off) we always look at the option which has a lower opportunity cost. So we can say that they are the most desirable trade-off.
Answer:
the heat capacity of the bolt is 13.9 J/K
Explanation:
J/K is short of " joule per kelvin", is the international system unit of heat capacity
heat energy = (mass of substance)(specific heat)(change in temperature)
Q = mc∆T
Q = heat energy (Joules, J)
m = mass of a substance (kg)
c = specific heat (units J/kg∙K)
∆ is a symbol meaning "the change in"
∆T = change in temperature (Kelvins, K)
Heat gained by water = heat lost by copper = Q = mC∆T = (50 g)(4.18 J/g/deg)(5 deg) = 1045 J = C x ∆T
C = 1045 J/75 = 13.9 J/deg
Answer:
$102,870
Explanation:
The computation of Total cash disbursements is shown below:-
Variable overhead = Direct labor budget × Variable overhead rate
= 8,100 × $1.40
= $11,340
Fixed expenses incurred in cash = Total fixed expenses - Depreciation
= $100,440 - $8,910
= $91,530
Total cash disbursements = Total variable manufacturing overhead + Fixed cash overhead
= $91,530 + $11,340
= $102,870
Therefore for computing the Total cash disbursements we simply applied the above formula.
