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:
The answer is: FALSE
Explanation:
Documents are the most significant evidence in most fraud cases. Those who commit fraud will generally try to manipulate documentary evidence. Investigating the company's databases and accounting records are the best way to get documentary evidence. Also, documentary evidence is considered to be more reliable than eyewitness testimony.
A check will be written with the amount of $95. A sales discount, like 5%, 10days, simply means, you'll get 5% discount if paid within 10 days from the date of invoice.
If you pay within the discount period, say 6 days from the invoice date, instead of paying $100, you'll pay just $95 ($100 × 95%). Computed another way as, ($100 - ($100 × 5%)).
Answer:
r = 0.099974 or 9.9974% rounded off to 10.00%
Explanation:
Using the constant growth model of DDM we calculate the price of a stock today which is expected to pay a dividend which increases at a constant rate through out. The DDM values a stock based on the present value of the expected future dividends from the stock. The formula for price under this model is,
P0 = D1 / r - g
Where,
- r is the required rate of return or cost of equity
- g is the constant growth rate in dividends
Plugging in the available values in the formula, we calculate r to be,
74.11 = 4.63 / (r - 0.0375)
74.11 * (r - 0.0375) = 4.63
74.11r - 2.779125 = 4.63
74.11r = 4.63 + 2.779125
r = 7.409125 / 74.11
r = 0.099974 or 9.9974% rounded off to 10.00%
