linked and table/indexed) will be most ap- propriate

Table/indexed.  
Let's look at the three options and see what their advantages and disadvantages are:  
Contiguous - In this scheme, the file is stored in contiguous blocks of the disk. It allows for easy random access of the data, but requires a contiguous sequence of blocks large enough to handle the entire file. Since the size of the file specified in this question varies quite a bit over it's lifespan, you're either going to be wasting a lot of space by having an allocation large enough to handle the maximum sized file, or the file will need to be copied whenever it grows and "bumps" into a file that was allocated after it. Because of this, this method is not the best.  
Linked - The file is stored as a single, or double linked list of file blocks. This allows for the file to grow or shrink as needed, using only the amount of space needed for the file. Unfortunately, this storage scheme doesn't allow for random access of the file contents and the file can only be accessed sequentially. The question for this problem doesn't specify how the file is being accessed, so as long as random access isn't required, then this would be a reasonable allocation scheme. But I'm assuming that random access will be required, in which case, this scheme isn't ideal.  
table/indexed - In this scheme, some disk blocks are used as tables to point to other disk blocks that actually contain the file data. It's almost as fast as contiguous allocation for random access of the file contents, yet allows for the growth and shrinkage of a file like linked allocation. As such, it handles all use cases at a relatively minor cost in total storage required. So this would be the most appropriate allocation scheme since the file access behavior wasn't specified in this question.

Holding other factors constant, if bad weather destroys the annual crop for carrots, it causes the supply curve for carrots to
Iteru [2.4K]

Options:

<em>a. Shift to the left, causing the prices of carrots to rise</em>

<em>b. Shift to the left, causing the prices of carrots to fall</em>

<em>c. Stay the same</em>

<em>d. The supply curve does not shift. Only the demand curve shifts.</em>

<u>Answer:</u>

<u>a. Shift to the left, causing the prices of carrots to rise</u>

<u>Explanation:</u>

Indeed, going by the law of supply and holding all other factors constant, we would expect the supply curve to shift to the left, which implies that there would be an increase in the price of carrots.

What this means is that because there are now fewer carrots in the market as a result of the effects of the bad weather, there would be scarcity and so sellers would increase prices.

Hawkins Inc. had pre-tax accounting income of $1,800,000 and a tax rate of 35% in 2017, its first year of operations. During 201
Butoxors [25]

Answer:

Hawkins Inc.

For 2017, the amount of income taxes payable for Hawkins Inc. is:

= $572,600.

Explanation:

a) Data and Calculations:

2017 tax rate = 35%

Pre-tax accounting income =   $1,800,000

2018 Rent from Barrett Co.            64,000

Less:

Exempt Municipal bond income  (80,000)

Tax Depreciation (in excess of

 book depreciation)                     (40,000)

2018 Installment sales revenue (108,000)

Adjusted taxable income       $1,636,000

Income tax (35%)                        572,600 (35% of $1,636,000)

Tax expense (provision)             630,000 (35% of $1,800,000)

b) The difference between the income tax payable of $572,600 and the provision for income tax expense for the year of $630,000 is due to temporary differences and exempt Municipal bond income.  The temporary differences are caused by the different timings of the recognition of revenue and expenses under the tax jurisdiction and the GAAP accounting.

LeCompte Corp. has $312,900 of assets, and it uses only common equity capital (zero debt). Its sales for the last year were $620
Gnom [1K]

Answer:

LeCompte Corp.

The profit margin that LeCompte Corp. would need in order to achieve the 15% ROE, holding everything else constant is:

A) 7.57%.

Explanation:

a) Data and Calculations:

Assets = $312,900

Common Equity = Assets = $312,900

Sales for the last year = $620,000

Net income after taxes = $24,655

Expected return on equity (ROE) = 15%

ROE (in amount) =  $312,900 * 15% = $46,935

Profit margin = Returns on Equity/ Sales * 100

= $46,935/$620,000 * 100

= 7.57%

b) The expected returns on equity in dollars is equal to the net income.  Therefore, we can use the ROE to calculate the profit margin.  The profit margin expresses the relationship between sales and profit.  It shows the profit made from each dollar sales.

True or false: standard rules exist to help managers identify appropriate allocation bases.
tangare [24]

False, standard rules doesn't exist to help managers identify appropriate allocation bases.

Standard Rules refers to strong moral commitments or ethics that allows smooth working of an organisation. It is basically fundamental requirements to govern an organisation. It could play a role in appropriate allocation bases but doesn't exist for it rather to keep check on principles and equality in an organisation. They are not legally binding. But, appropriate allocation bases require judgement. Managers use- the direct method or the sequential (or step) method or the reciprocal method, to develop judgements about allocation bases. Hence, the statement is false.
