Answer:

The Expected time a customer spends in the system is 4

Explanation:

According to the given data we have the following:

Arrival rate A = 1 every other minute = 30/hour or (30/60) per minute

Service rate S = 84 seconds = 60×60/84= 42.86 customers per hour

System utilization factor P = A/S = 30/42.86 = 0.699

Length of the system L = P/(1-P) = 0.699/(1-0.699) = 2.322

Therefore, Expected time a customer spends in the system = L/A = 2.322/(30/60) = 4.644=4

Explanation:

Extra cost=8%

Saving per year=15%

Extra Cost of home=250000*0.08=$20000

Let the energy saving required per year to justify the home=x

Extra cost paid = P.v of energy saving

20000=x*Annuity factor(10%@30 years)

20000=x*9.427

X=2121.566

If, for a particular process, δh=-405 kjmol and δs=-92 jmol k, the process will be?
Nadusha1986 [10]

The process can be: spontaneous below a sure temperature.

A spontaneous procedure is one that takes place certainly under certain situations. A nonspontaneous procedure, alternatively, will not take region unless it's far “driven” by the continual input of power from an external source.

A spontaneous method is one that happens on its personal, with no strength input from the outdoor. as an example, a ball will roll down an incline; water will waft downhill; ice will soften into the water; radioisotopes will decay, and iron will rust.

A method this is spontaneous in a single direction below a selected set of situations is nonspontaneous in the reverse course. At room temperature and normal atmospheric stress, for example, ice will spontaneously melt, however, water will now not spontaneously freeze.

Dmitry [639]

Answer:

The financial statements effects of the appropriation are as follows:

a) Retained Earnings will reduce by $65,000 in the Income Statement and the Balance Sheet.

b) Cash balance will also reduce by $65,000 in the Balance Sheet.

Explanation:

Normally, partnerships can distribute or appropriate their profits according to their partnership agreements.  However, there may be restrictive loan covenants that can specify how much profits partnerships can distribute among the partners.  The purpose of such covenants is to ensure that the ability of the partnership to repay loans are not compromised through profit appropriations.

Financial institutions, therefore, to secure the loans advanced to businesses may include restrictive covenants.  Some restrictive covenants may specify the minimum cash balance to maintain.  Restrictive covenants, generally, remain measures to overcome unwanted business outcomes.  It is a form of insurance against loan repayments.
