1500 m^3/h of a gas mixture containing 20 mole% solute and rest inert enters the absorber at 250 K temperature and 106.6 kPa pressure to remove 80% of original solute. solute free water used for absorption contains 10 mole% solute when it leaves the tower at the bottom. calculate the solvent flow rate to tower.

Your company has just announced a 7-percent price increase on your entire product line and you are meeting with your most important customer. She announces that your competitor has already been to see her and will not raise prices for at least 24 months. What do you do to keep the customer?

Examine the key reasons why a business may not want to hold too much or too little working capital. Provide examples that illustrate the consequences of either situation.

You have looked at the current financial statements for Reigle Homes, Co. The company has an EBIT of $2,850,000 this year. Depreciation, the increase in net working capital, and capital spending were $225,000, $90,000, and $415,000, respectively. You expect that over the next five years, EBIT will grow at 16 percent per year, depreciation and capital spending will grow at 21 percent per year, and NWC will grow at 11 percent per year. The company has $15,100,000 in debt and 345,000 shares outstanding. You believe that sales in five years will be $22,600,000 and the price-sales ratio will be 2.4. The company’s WACC is 8.5 percent and the tax rate is 21 percent.

The McGee Corporation finds it is necessary to determine its marginal cost of capital. McGee’s current capital structure calls for 40 percent debt, 5 percent preferred stock, and 55 percent common equity. Initially, common equity will be in the form of retained earnings (K_e) and then new common stock (K_n). The costs of the various sources of financing are as follows: debt, 5.6 percent; preferred stock, 11.0 percent; retained earnings, 8.0 percent; and new common stock, 9.4 percent.

a. What is the initial weighted average cost of capital? (Include debt, preferred stock, and common equity in the form of retained earnings, K_e.) (Do not round intermediate calculations. Input your answers as a percent rounded to 2 decimal places.)

  
  b. If the firm has $22.0 million in retained earnings, at what size capital structure will the firm run out of retained earnings? (Enter your answer in millions of dollars (e.g., $10 million should be entered as "10").)

Capital Structure Size (X) _______ million

c. What will the marginal cost of capital be immediately after that point? (Equity will remain at 55 percent of the capital structure, but will all be in the form of new common stock, K_n.) (Do not round intermediate calculations. Input your answer as a percent rounded to 2 decimal places.)

Marginal Cost of Capital ______%

d. The 5.6 percent cost of debt referred to above applies only to the first $40 million of debt. After that, the cost of debt will be 7.6 percent. At what size capital structure will there be a change in the cost of debt? (Enter your answer in millions of dollars (e.g., $10 million should be entered as "10").)

Capital Structure Size _____ million

e. What will the marginal cost of capital be immediately after that point? (Consider the facts in both parts c and d.) (Do not round intermediate calculations. Input your answer as a percent rounded to 2 decimal places.)

Marginal Cost of Capital _____%

Why is it important for the researcher to control extraneous environmental and social variables in an experiment? How does a researcher do this?

what is the minimum number of IV conditions in an experiment?

What are experimental and control groups? Do all experiments have to have a control groups?

What are experimental and control groups? Do all experiments have to have a control group.

How can you tell if a variable can serve as an IV?

A volume of 12.95 mL of 0.1080 M NaOH solution was used to titrate a 0.596 g sample of unknown containing K₂HPO₄.

a. What is the molecular mass of K₂HPO₄? (report answers to 4 or 5 significant figures)

b. What is the percent by mass of K₂HPO₄ in the unknown?

c. In this problem what mass of sample in grams would be needed to deliver about 22.00 mL in the next trial?

d. In the second trial above, exactly 0.996 g was transferred into a flask to be titrated. If the initial buret reading is 0.10 mL, predict what the final buret reading be.

1. A priority queue is a special queue that adjusts the location of items based on some priority value. When inserted, a new value is placed in the queue ahead of every other item that has a lower priority than it. This gives us a queue that removes items from the front removing highest priority first, and from items with similar priority the ones that were inserted first. For example, if we inserted the following items with the priority {A, 1}, {B,2}, {C,2}, {D,3}, {E,1} where the lower number is a lower priority, our queue will have the items from front to back: D,B,C,A,E. Using the partial code below, you are to implement the Enqueue method so that the new node is inserted into the appropriate place in the queue based on the priority. (Assume that a higher number is higher priority, for example 0 is lowest and 10 is highest)

class Node<V,P>

{

      public V value;

      public P priority;

      public Node<V,P> next;

      Node(V value, P priority)

      {

           this.value = value;

           this.priority = priority;

      }

}

class PriorityQueue<V,P>

{

      private Node<V,P> head;

      private Node<V,P> tail;

      ...

      public void Enqueue(V value, P priority)

      {
