Cohen Chemicals, Inc. produces two types of photo-developing fluids. The first, a black-and-white picture chemical, costs Cohen $2,500 per ton to produce. The second, a color photo chemical, costs $3,000 per ton. Based on an analysis of current inventory levels and outstanding orders, Cohen's production manager has specified that at least 30 tons of the black-and-white chemical and at least 20 tons of the color chemical must be produced during the next month. In addition, the manger notes that an existing inventory of a highly perishable raw material needed in both chemicals must be used within 30 days. To avoid wasting the expensive raw material, Cohen must produce a total of at least 60 tons of the photo chemicals in the next month. What is the lowest cost to Cohen Chemicals? post the answers on Excel please. include a photo of the excel spreadsheet

****JAVA Program****

Make a LandTract class with the following fields:

• length - an int containing the tract's length
• width - an int containing the tract's width

The class should also have the following methods :

• area - returns an int representing the tract's area
• equals - takes another LandTract object as a parameter and returns a boolean saying
whether or not the two tracts have the same dimensions (This applies regardless of whether the dimensions match up. i.e., if the length of the first is the same as the width of the other and vice versa, that counts as having equal dimensions.)
• toString - returns a String with details about the LandTract object in the format:
LandTract object with length 30 and width 40
(If, for example, the LandTract object had a length of 30 and a width of 40.)

Write a separate program that asks the user to enter the dimensions for the two tracts of
land (in the order length of the first, width of the first, length of the second, width of the second). The program should print the output of two tracts' toString methods followed by a sentence stating whether or not the tracts have equal dimensions. (If the tracts have the same dimensions, print, "The two tracts have the same size." Otherwise, print, "The two tracts do not have the same size.") Print all three statements on separate lines.

A sediment sample taken from a lignite strip-mine pit contains highly alkaline (pH 10) water. Cations were displaced from the sediment by treatment with HCl. A total analysis of cations in the leachate yielded, on the basis of millimoles per 100 g of dry sediment: 160 mmol Na+, 10 mmol K+, 30 mmol Mg2+, and 70 mmol Ca2+. What is the cation exchange capacity of the sediment in milliequivalents per 100 g of dry sediment? Why does H+ not have to be considered in this case?

On January 1, Morris Company offered a customer a 10% trade discount if the customer purchases 1,000 units of an item within the next 6 months. Each item sells for $100. Based on the customer’s previous purchase history, Morris believes there is a 60% chance that the customer will purchase more than 1,000 units. On January 10, the customer purchases 200 units on credit. Required: How much revenue should Morris recognize related to this customer? Prepare the entry to record the sale on account on January 10.

Problem 3: Astronaut testing At its Ames Research Center, NASA uses its large 20-G centrifuge to test the effects of very large accelerations (hypergravity) on test pilots and astronauts. In this device, an arm 8.84 m long rotates about one end in a horizontal plane, and the astronaut is strapped in at the other end. Suppose that he is aligned along the arm with his head at the outermost end. The maximum sustained acceleration to which humans are subjected in this machine is typically 12.5g.

a) How fast must the astronauts head be moving to experience this maximum acceleration?

b) What is the angular velocity ω of the arm?

c) What is the difference between the acceleration of his head and feet if the astronaut is 2.00 m tall?

Many managers and executives are too rushed to read long journal articles, but they are eager to stay current in their fields. Assume your boss has asked you to help him stay abreast of research in his field. He asks you to submit to him one executive summary every month on an article of interest.

Your Task. In your field of study, select a professional journal, such as the Journal of Management. Using ProQuest, Factiva, EBSCO, or some other database, look for articles in your target journal. Select an article that is at least five pages long and is interesting to you. Write an executive summary in a memo format. Include an introduction that might begin with As you requested, I am submitting this executive summary of . . . . Identify the author, article title, journal, and date of publication. Explain what the author intended to do in the study or article. Summarize three or four of the most important findings of the study or article. Use descriptive, or “talking,” headings rather than functional headings. Summarize any recommendations made. Your boss would also like a concluding statement indicating your reaction to the article. Address your memo to Marcus E. Fratelli.
