Did Amazon succeed in China? What did it learn?

A 6.210 gram sample of an organic compound containing C, H and O is analyzed by combustion analysis and 10.34 grams of CO2 and 3.388 grams of H2O are produced. In a separate experiment, the molar mass is found to be 132.1 g/mol. Determine the empirical formula and the molecular formula of the organic compound.

1. Sequential Method

   Jasmine Company manufactures both pesticide and liquid fertilizer, with each product manufactured in separate departments. Three support departments support the production departments: Power, General Factory, and Purchasing. Budgeted data on the five departments are as follows:

   	Support Departments		Producing Departments
   	Power	General Factory	Purchasing	Pesticide	Liquid Fertilizer
   Overhead	$90,000	$312,000	$165,000	$78,500	$107,700
   Square feet	1,500	—	1,500	4,200	4,800
   Machine hours	—	1,403	1,345	24,000	8,000
   Purchase orders	20	40	—	120	60

   The company does not break overhead into fixed and variable components. The bases for allocation are power—machine hours; general factory—square feet; and purchasing—purchase orders.

   The company has decided to use the sequential method of allocation instead of the direct method. The support departments are ranked in order of highest cost to lowest cost.

   Required:

   1. Allocate the overhead costs to the producing departments using the sequential method. Carry out allocation ratios to four decimal places. Use these numbers for subsequent calculations. Round allocated costs to the nearest dollar. If an amount is zero, enter "0".

   Allocation ratios:

   	Power	General Factory	Purchasing	Pesticide	Liquid Fertilizer
   Square feet
   Machine hours
   Purchase orders

   Cost allocation:

   	Power	General Factory	Purchasing	Pesticide	Liquid Fertilizer
   Direct costs	$	$	$	$	$
   General Factory
   Purchasing
   Power
   Total	$	$	$	$	$

   2. Using machine hours, compute departmental overhead rates. (Round the overhead rates to the nearest cent.)

   	Overhead Rates
   Pesticide	$ per machine hour
   Liquid Fertilizer	$ per machine hour

Why is a visual analysis important in communicating findings in a business research paper or proposal? Give an example of a visual analysis that would be appropriate for your paper and presentation (rising health-care costs). Describe acceptable report page design methods to make your paper or presentation visually appealing.

Q. A sequence X1, X2, ... , Xn is said to be cyclically sorted if the smallest number in the sequence is Xi for some unknown ?, and the sequence Xi, Xi+1, Xn, ... , X1, X2,....Xi-1 is sorted in an increasing order. Design an algorithm to find the position of the minimal element in a cyclically sorted ? distinct elements. (6 points) If your algorithm uses recursion, you need so show the recurrence function. Otherwise, show a closed-end form of the running time function. (2 points) Show that your algorithm in ?(log ?) time. (2 points) (No need to prove the bound).

Direct Method and Overhead Rates

The company does not break overhead into fixed and variable components. The bases for allocation are power—machine hours; general factory—square feet; and purchasing—purchase orders.

Required:

1. Allocate the overhead costs to the producing departments using the direct method. If required, round your allocation ratios to four decimal places and round allocated costs to the nearest dollar and use the rounded values for the subsequent calculations.

Cost assignment:

2. Using machine hours, compute departmental overhead rates. (Round the overhead rates to the nearest cent.)

Select one of the key concepts from below for your Discussion response for this week. Be sure to identify the name of the organization. If organization’s name needs to stay anonymous, please check with the instructor ahead of time regarding how to approach that.

• Discuss different types of operations management and project management activities that occur at the organization of your choice.
• Provide examples of single-factor and multifactor productivity measures.
• Provide two examples of operations management activities at an organization you considered and its inputs and outputs, productivity measures, and classify whether it is a goods or services producing organization.

Be sure to post an initial, about 250-word substantive response

On January 1, 2021, Marshall Company acquired 100 percent of the outstanding common stock of Tucker Company. To acquire these shares, Marshall issued $310,000 in long-term liabilities and 20,000 shares of common stock having a par value of $1 per share but a fair value of $10 per share. Marshall paid $24,000 to accountants, lawyers, and brokers for assistance in the acquisition and another $9,000 in connection with stock issuance costs. Prior to these transactions, the balance sheets for the two companies were as follows: Marshall Company Book Value Tucker Company Book Value Cash $ 75,000 $ 38,800 Receivables 354,000 90,000 Inventory 380,000 229,000 Land 246,000 253,000 Buildings (net) 476,000 274,000 Equipment (net) 174,000 50,400 Accounts payable (241,000 ) (41,400 ) Long-term liabilities (480,000 ) (310,000 ) Common stock—$1 par value (110,000 ) Common stock—$20 par value (120,000 ) Additional paid-in capital (360,000 ) 0 Retained earnings, 1/1/21 (514,000 ) (463,800 ) Note: Parentheses indicate a credit balance. In Marshall’s appraisal of Tucker, it deemed three accounts to be undervalued on the subsidiary’s books: Inventory by $9,000, Land by $25,800, and Buildings by $32,200. Marshall plans to maintain Tucker’s separate legal identity and to operate Tucker as a wholly owned subsidiary. Determine the amounts that Marshall Company would report in its postacquisition balance sheet. In preparing the postacquisition balance sheet, any required adjustments to income accounts from the acquisition should be closed to Marshall’s retained earnings. Other accounts will also need to be added or adjusted to reflect the journal entries Marshall prepared in recording the acquisition. To verify the answers found in part (a), prepare a worksheet to consolidate the balance sheets of these two companies as of January 1, 2021.
