5 0

Answer:

0.066 cent

Explanation:

Efficiency (E) = Energy output (Eo)/Energy input (Ei)

Eo = E × Ei

E = 0.6

Ei = mass × acceleration due to gravity × height

mass = 100lbm = 100×0.45359kg = 45.359kg, height = 300ft = 300/3.2808 = 91.44m

Ei = 45.359×9.8×91.44 = 40646.7Ws = 40.6467kWs = 40.6467kWs × 1h/3600s = 0.011kWh

Eo = 0.6 × 0.011kWh = 0.0066kWh

1kWh = 10 cents

0.0066kWh = 0.0066×10 = 0.066 cent

Profit Suppose that the daily profit (in dollars) from the production and sale of x units of a product is given byP180xx21000200
algol13

Answer:

The answer is "1798".

Explanation:

\to p=180x-\frac{x^{2}}{1000}-2000

In order to find the rate of profit increase each day, we differentiate between the money demand function and the time t.

\to \frac{dp}{dt}=180\frac{dx}{dt}-\frac{2x}{1000}\frac{dx}{dt} \\\\\to \frac{dp}{dt}=\frac{dx}{dt}\left (180-\frac{2x}{1000} \right ).................(1)

Calculate \frac{dp}{dt} when x=100

\frac{dx}{dt}=10  (Extension rate of produced and delivered units per day)

x=100 \ and\ \frac{dx}{dt}=10 ......... in \ \ eq(1)\\\\\frac{dp}{dt} = 10\left (180-\frac{2(100)}{1000} \right )\\\\  

    =10\left (180-0.2\right ) \\\\=1798 \\\\

Cardinal Industries had the following operating results for 2018: Sales = $34,318; Cost of goods sold = $24,212; Depreciation ex
JulsSmile [24]

Answer:

a  $1,091.22

b $9,798.22

c - $1,709.78

d-1 $2,710

d-2  - $4,419.78

Explanation:

a. The computation of the net income is shown below:

= Sales - cost of good sold - depreciation expense - interest expense - income tax expense  

= $34,318 - $24,212 - $5,997 - $2,710 - $307.78

= $1,091.22

The income tax expense  

= ($34,318 - $24,212 - $5,997 - $2,710) × 22%  

=  $307.78

b. The operating cash flow is shown below:

= EBIT + Depreciation - Income tax expense

where,  

EBIT = Sales - cost of good sold - depreciation expense  

= $34,318 - $24,212 - $5,997

= $4,109

And all other items would remain same

Now put these values to the above formula  

So, the value would equal to

= $4,109 + $5,997 - $307.78

= $9,798.22

c. Computation of the cash flow from assets for 2019 is shown below:

= Operating cash flow - net capital spending - changes in working capital

where, net capital capital = ending fixed assets - beginning fixed assets + depreciation  

= $24,502 - $19,940 + $5,997

= $10,559

Changes in working capital = (ending balance of current assets - ending balance of current liabilities) - (beginning balance of current assets - beginning balance of current liabilities)

= ($8,684 -  $4,673 ) - ($7,054 - $3,992)

= $4,011 - $3,062

= $949

Now put these values to the above formula  

So, the value would equal to

= $9,798.22 - $ $10,559 - $949

= - $1,709.78

d.1 The computation of the cash flow to creditors is shown below:

= Interest expense - ending balance of long term debt + beginning balance of long term debt  

= $2,710 - 0 + 0

= $2,710

d.2 The computation of the cash flow to stockholder is shown below:

= Cash flow from asset - cash flow to creditors

= - $1,709.78 - $2,710

= - $4,419.78

Leto [7]

Answer:

benefit those in the worst position.

Explanation:

Rawls theory is based on the concept that no inequalities shall prevail in the country. Although some inequalities are unavoidable.

In those circumstances, when Rawls shall agree to such inequalities, and in-fact, further states that it shall benefit all the people. But for this he states that those in the worst position shall be benefited first and with maximum.

This shall create an equality as these people facing inequality will not be criticised further for any purpose, if they are paid off well in the first instance only.

Describe the abilities of someone with analytical/research skills. Somebody please help me!!!!!!!!!!!!!
Neko [114]
Somebody whose job is to provide analytics or research should always be someone who is very good at quantitative analysis.  They should be good with math and numbers, because their job is to analyze a business.  The same goes for research.  A good researcher is good at math because they have to analyze large datasets.  This person would also be pretty detail-oriented because they need to make sure that they are not making small mistakes, as small mistakes could result in poor decisions that come out of their analysis.

Does that make sense?
