Answer:

Explanation:

a. cycle time = Total time available/ production rate required

cycle time = (60*60)/180 = 3600/180 = 20sec per unit

b. theoretical minimum for the number of work-stations that Rosenberg can achieve in this assembly line.

Total task time = 12+15+8+5+20 = 60

theoretical minimum for the number of work-stations = Total task time/cycle time

theoretical minimum for the number of work-stations = 60/20 = 3stations

c. idle time

standard hour for the job is calculated as

standard hours allowed for actual production = unit produced * labor time required

The question does not contain the required information to solve it. Information such standard hours is not given.

If marginal product is greater than average product:
babunello [35]

Answer:

(D). Average product must be rising.

Explanation:

Average product is gotten by dividing the total product of a firm, by the labor quantity (such as the number of workers). This gives the average product per worker.

Marginal product shows the change in total productivity caused by an additional unit of labor (such as a newly hired worker).

If the extra productivity brought about by an additional worker (marginal product) is higher than the average productivity per worker in a firm (the average product), then this marginal productivity, when added to the total, will raise the average productivity of the firm.

This explains why "average product must be rising as long as marginal product is greater than it."

Similarly, once marginal productivity drops below average productivity, then average product starts to decline.

uestion 31 Oriole Company has the following inventory data: July 1 Beginning inventory 114 units at $19 $2166 7 Purchases 399 un
lina2011 [118]

Answer:

$7,714

Explanation:

The computation of the cost of good sold under LIFO method is shown below

But before that following calculations need to be done

Goods sold = Beginning inventory + Purchases - Ending inventory

= 114 + (399 + 57) - 190

= 380 units

Now 380 units sold would include 57 units of July 22 purchases and balance i.e. (380-57)  323 units of July 7 purchases

So, cost of goods sold

= (57 × 22) + (323 ×20)

= $7,714

In its first year of existence (year 1), SCC corporation (a C corporation) reported a loss for tax purposes of $30,000. How much
devlian [24]

Answer:

SCC won't pay any tax

Explanation:

Their loss of $30,000 in year 1 will be unused and made available to counterbalance the total generated earnings in year 2.

The $20,000 earnings in year 2 can be used to counterbalance the whole taxable income; so, SCC will not pay pay tax. SCC will have a ($10,000) loss carryover available for year 3 and beyond
