Answer: (a ) 4 per hour (b ) 4.5 minutes (c ) 3 minutes

Explanation:

Average time between customer arrival = 15 minutes

Average service time = 10 minutes

(a) To calculate the customer arrival rate

Arrival rate = 1 / time between Arrival

= 1 / 15

= 0.066 × 60

= 4 per hour

(b) To calculate the average number of customers in queue

( Arrival time )^2 / service time ( service time - Arrival time)

= (15)^2 / 10 ( 10 - 15)

= 225 / 10 (-5)

= 225 / 50

= 4.5 minutes

(c) To calculate the average time customers spend in the system

Arrival time / service time - Arrival time

= 15 / 10 - 15

= 15/ -5

= 3 minutes

You are the newly appointed sales manager of the Rock Record Company and have been charged with the task of increasing revenues.
mote1985 [20]

Answer:

Increase price.

Explanation:

Price elasticity is the degree of responsiveness of quantity demanded to changes in price. Ideally as price increases quantity demanded reduces. When prices reduce quantity demanded increases.

As a new manager of Rock Record company, if the economics consultants inform you the price elasticity is less than one it means quantity does not change with increase in price.

So price can be increased without a corresponding decrease in price. The goal of higher revenue can be achieved by increasing the product price.

marshall27 [118]

Answer:

Current Ratio= Current Assets/ Current Liabilities

Explanation:

Current Ratio= Current Assets/ Current Liabilities

The current ratio is an important measure of a company's ability to pay its short term obligations. It is defined as current assets divided by current liabilities.

Current assets are cash and other resources that are expected to be sold or used within one year or the company's operating cycle , whichever is longer. Examples are cash, short term investments , accounts receivable, short term notes receivable, goods for sale ( called merchandise or inventory) and prepaid expenses. Prepaid expenses are usually listed last because they will not be converted to cash ( instead they are used).

Current liabilities are obligations due to be paid or settled within one year of operating cycle, whichever is longer. they are usually settled by paying out current assets such as cash . Current liabilities often include accounts payable , notes payable, wages payable, taxes payable, interest payable and unearned revenues. Also any portion of a long term liability due to be paid within one year or the operating cycle whichever is longer is a current liability.

A) You have just moved into a new apartment and are trying to arrange your bedroom. You would like to move your dresser of weigh
notsponge [240]

Answer:

A. W = 0joule

B.W = d * w * cos (90 -ø)

Explanation:

work done is force multiplied by distance since the distance covered by the dresser is zero so automatically work done in moving the dresser is 0 (zero)

B. The component of weight of box along the inclined plane = w * cos ( 90 - ø )

Where ø is the angle of inclination to the horizontal

W = weight of body due to gravity.

Since the distance traveled by box due to gravity = d

So therefore:

W = d * w * cos (90 -ø)

W = work done
