Solution:
Given Information,
Heat input is ( 
) = 5.5 × 
Btu/h
Combustion efficiency of the boiler (
) = 0.7
Combustion efficiency after turn up (
) = 0.8
Operation Hour (t) = 5200h
Unit cost (c) = 
Calculate heat output from the boiler 
= x
= 5.5 x x 0.7
= 3.85 x Btu/h
Calculate the heat input to the boiler after the tune-up
= / 
= 3.85 x / 0.8
= 4.8125 x Btu/h
Calculate the saved energy after the tune-up
= -
= 5.5 x - 4.8125 x Btu/h
= 0.6875 x Btu/h
Calculate the annual energy saving ( 
)
= x t
= ( 0.6875 x Btu/h ) ( 5200 hr/yr)
= 3575 x Btu/h
Calculate the annual cost saving
Annual cost saving = 
x Unit cost
= 3575 x Btu/h x
= 82225
Answer:
d. can be estimated even if the firm’s bonds are not publicly traded, by looking at the yield to maturity on bonds outstanding from peer group firms with similar ratings and maturity
Explanation:
The cost of Debt for a firm is estimated even if the firm's bonds are not publicly traded, by looking at the yield on bonds outstanding from peer group firms with similar ratings and maturity.
<h2>Every country operate in a different yet similar system of both political and social affairs.</h2>
Explanation:
Every country operate in a different yet similar system of both political and social affairs. In terms of political differences, some countries have parliamentary governments while some countries like the US have presidential governments.
Regardless of how each country operate politically, most of the operational system of these countries are embedded in democracy and the general welfare of its citizens. The differences occur because of these operational systems of each country. They could differ in policies, reforms or laws which are based on the interests of its people and the nation.
In economic terms, the differences occur when governments prioritize what economic policies or model they choose to implement. Economic systems of a country change according to the need of the times. For instance, China initially, after its independence, chose to remain a closed economy until it reformed its policies in 1978 to finally open up the country.
Legal systems of countries differ from one another as every country use a civil law system based on its cultural, social, political and historical circumstances. For instance, in US each state has the power to establish its own legal procedures while in some country, every state must follow a uniform civil code.
As we know the political economy refers to both the political and economic systems of a country, management practice of national differences is important to taken into account before securing economic relations with another country. Management practice of national differences helps in finding favorable economic and political systems around the world for a country to make both economic and political partnership with.
Answer:
C. Fixed Interval
Explanation:
"Fixed Interval" is a type of <em>Reinforcement Schedule. </em>The "reward" in the situation above is the<em> salary given to the employees</em> during Wednesdays. As noticed, their productivity increases over the week, with the peak on Wednesday.
The<u> "peak" of productivity</u> is the<u> exhibited behavior during pay day.</u> They try to work hard in order to receive a salary. <em>They become more inspired to work during the salary day.</em> It is followed by<em> </em><em>less productivity on Thursdays</em><em> </em>because they have already been rewarded.
Such reinforcement schedule is called the "fixed interval." This also means that their productivity will not increase if they will not be paid.
So, this explains the answer.
Answer:
to obtain 10,000 hours of light you would need:
option 1)
10 incandescent light bulbs costing $0.50 each = $5
this incandescent light bulbs will consume 60 x 10,000 = 60,000 watts or 60 kWh = 60 x $0.10 = $6 in electricity
total costs using incandescent light bulbs = $5 + $6 = $11
option 2)
1 fluorescent light bulb = $4
this fluorescent light bulb will consume 15 x 10,000 = 15,000 watts or 15 kWh = 15 x $0.10 = $1.50
total costs using fluorescent light bulbs = $4 + $1.50 = $5.50
