A steam generation system at a biomassfueled power plant uses an electrostatic precipitator (ESP) to clean its gaseous effluents

. The power plant has consistently made use of the same type of ESP over the past several years. The installed cost of a new ESP has been relatively constant at $80,000. Records of operation and maintenance expenses indicate the following average expenses per year as a function of the age of the ESP. The MVs of the ESP are also reasonably well known as a function of age. Determine the best time to replace the ESP if the MARR
is 15% per year

A steam generation system at a biomass-fueled power plant uses an electrostatic precipitator (ESP) to clean its gaseous effluents. the best time to replace the ESP is mathematically given as

EUAC3= 46377.48

<h3>What is the best time to replace the ESP if the MARR is 15% per year?</h3>

Generally, the equation for the EUAC for the yrs of operation  is mathematically given as

For Year 1

EUAC1 = 85000 * (A/P,9%,1) + 25000 - 63000 * (A/F,9%,1)

EUAC1 = 54650

Solving till year 5

EUAC2= 46525.60

EUAC3= 46377.48

EUAC4= 48730.91

EUAC5= 50730.79

In conclusion,  the best time to replace the ESP if the MARR is 15% per year will be at the EUAC3= 46377.48  since EUAC is the lowest at that year.

B. effectively harnesses the incentives of workers and entrepreneurs.

D. has slowly lost ground to emerging command systems.

Answer:

An economic system can be defined as a series of governmental or societal arrangements and a coordinating mechanism used for the allocation of available resources, economic inputs, goods and services across a particular country. The economic system differs according to the method used to coordinate economic activities and who the factors of production belongs to.

Generally, there are basically two (2) main types of economic systems and these are;

2. Market systems.

The market system effectively harnesses the incentives of workers and entrepreneurs because workers are able to engage in division of labor and are well compensated for their efficiency in service while the entrepreneur are usually rewarded with an increase in sales and profits.

The market system allows participants to have property rights such as trademarks, patents and copyright. Also, market systems are regulated by the competition among individuals (traders or entrepreneurs) and this gives direction to the market as they pursue self interests and are independent.

Beatrice invests $1,410 in an account that pays 3 percent simple interest. How much more could she have earned over a 4-year per
mixas84 [53]

Answer:

$7.77

Explanation:

The answer would be the difference between compound and simple interest

Simple interest = principal x time x interest

$1,410 x 0.03 x 4 = $169.20

Compound interest = future value - present value

future value = Principal ( 1 + interest)^n

$1,410 ( 1.03)^4 = $1586.96

$1586.96 -$1,410 = $176.97

Difference = $176.97 - $169.20 = $7.77

From the word itself, "values-led" business, this type of businesses are more inclined to doing what is right and moral by promoting values rather than thinking too much about the profit that comes from the sales of the manufactured goods.

Sloan [31]

If, in the market for money, the amount of money supplied exceeds the amount of money households and businesses want to hold, the interest rate will  rise, causing households and businesses to hold less money.

Option A

<u>Explanation: </u>

Fiscal policy is the central bank's macroeconomic policy. This covers the supply of money and interest rate control and is also the demand-side economic strategy of a country's government for achieving macroeconomic targets such as inflation, investment, productivity, and liquidity.

If the required quantity is above the amount given, people sell the property to obtain money like bonds. It leads to an increase in bond supply, a drop in bond prices and a higher market interest rate. If the volume supplied meets the necessary number, capital is increasing by purchasing a certain property, such as bonds.

The supply of money meets the demand for money, and the real rate of interest is higher than the number of equilibrium.

sergiy2304 [10]
<h2>In the short run, these workers are <u>variable</u> inputs, and the ovens are <u>Fixed</u> inputs.</h2>

Explanation:

By analyzing the information, we can understand that, Megan can grow slowly and steadily because the constraint here is that, Megan has so many people to work but they are students and he cannot buy more than 2 oven's at present considering his financial background and the size of the kitchen.

So the wise work is that, he keeps changing the number of workers every time but the number of oven to be used every time is only 2.

So workers are variable (changing) and ovens are fixed.
