They are all in their currency in billions and I need to make them into US dollar. Like Yen is 84.5 billion yen and also 14.2 billion yen, what are they if their converted to US dollars. Do that for all in the table below. Please show formula

Consider an economy with a production function given by Y =K^1/4 (EL)^3/4 . The depreciation rate is = 0.1, the population growth rate is n = 0.02 and the technological growth rate is g = 0.03. The economy's current savings rate is s = 0.3 and the current level of capital per effective worker K₀ = 1. Answer the following questions.

1. What is the consumption per effective worker in the current year (C₀) ?
2. What is the capital per effective worker in the next period (k₁) ?
3. What is the steady state level of output per effective worker (y*) ?
4. Find the golden rule level of output per-effective worker (y_G) ?
5. Compare the economy's savings rate with the golden-rule savings rate. Is the economy saving less ?

A metal cylinder of mass ? = 5 kg with a coaxial hole is sliding horizontally on a metal rod. A spring with spring constant ? = 500 N/m is attached to the cylinder. The other end of the spring is attached on a table at a vertical distance of ℎ = 0.3 m below the cylinder. The spring has an equilibrium length of ?_0 = 0.5 m.

a) What is the horizontal position ?0 of the cylinder when the spring is at its natural equilibrium length of ?0 = 0.5 m? Define the attachment point of the spring on the table as position ? = 0.

b) What is the length ? of the spring when the cylinder is at any given position ??

c) Draw a free-body diagram of the cylinder.

d) Show that the horizontal force from the spring on the cylinder is: ?? = −?? (1 − ?0 √? 2 + ℎ 2 )

Microsoft has an equity value of $250B, but has only $10B in debt. Management decides they’d like to increase the D/(D+E) ratio to 40% and use the proceeds to repurchase shares of equity, i.e. a leveraged recapitalization.

a) Before the recapitalization, the debt is considered risk-free and the equity has a beta of 1.13; afterwards, the debt beta becomes 0.3. How much debt does Microsoft issue? By how much has this restructuring changed the riskiness of equity in Microsoft, i.e. what is
the equity beta after the recapitalization?

b. If the risk-free rate is 3% and the expected market return is 9%, what are the expected
returns to equity holders before and after the recapitalization?

Please answer all parts of this question.

In order to analyze water samples using a spectrophotometer or plate reader, it is necessary to turn the molecules of nitrate into a dye molecule that can be quantified. The first step in turning nitrate (NO₃^-)  into a dye molecule is reducing it to a molecule of nitrite (NO₂^-). This is done by reacting the NO₃^- with cadmium.

After the reduction reaction, the NO₂^- is reacted with two additional reagents. The first reagent, Reagent A, is a solution of sulfanilamide and hydrochloric acid. The second reagent, Reagent B, is a solution of N-(1-naphthyl)-ethylenediamine, called NNED for short. The compounds are mixed with the water sample and produce a purple color. The intensity of the purple color is directly related to the concentration of nitrite in the water sample. We can measure how purple the water turns as absorbance on a spectrophotometer and then convert the absorbance to concentration of nitrate.

To make Reagent A, we will need to make a solution of 10.0 g of sulfanilamide in 1 L of 2.4 molar hydrochloric acid (HCl).

The stock solution of HCl is 12 molar HCl. How many milliliters (mL) of 12 M HCl would you add to produce 0.3 liters (L) of 2.4M HCl?  mL HCl

After creating 0.3 L of 2.4 molar HCl solution, how many grams of sulfanilamide will be added?  

g sulfanilamide

41) After reacting the nitrate with cadmium to produce nitrite, the nitrite is then reacting with sulfanilamide and N-(1-naphthyl)-ethylenediamine, to produce a purple dye molecule that can be quantified on a spectrophotometer. The N-(1-naphthyl)-ethylenediamine, called NNED for convenience, reagent is made by mixing 1 gram of NNED in 1 liter of water. However, we don't always want to make an entire liter of solution because the NNED solution only lasts about 1 month before going bad and turning brown. How many milligrams of NNED will need to be added to make 0.15 liters of solution?

Hi there! I can not find solution of Octave Levenspiel Chapter 26. I need it immediately. Can you please help me!Thank you.

A solid feed consisting of

20 wt% of 1-mm particles and smaller

30 wt% of 2-mm particles

50 wt% of 4-mm particles

passes through a rotating tubular reactor somewhat like a cement kiln where it reacts with gas to give a hard nonfriable solid product (SCMI reaction control, T = 4 h for 4-mm particles).

26.3. Find the residence time needed for 100% conversion of solids.

26.4. Find the mean conversion of the solids for a residence time of 15 min.

26.5. Particles of uniform size are 60% converted on the average (shrinking core model with reaction controlling) when flowing through a single fluidized bed. If the reactor is made twice as large but contains the same amount of solids and with the same gas environment what would be the conversion of solids?

26.6. Solids of unchanging size, R = 0.3 mm, are reacted with gas in a steady flow bench scale fluidized reactor with the following result. F, = 10 gmlsec, W = 1000 gm, X, = 0.75 Also, the conversion is strongly temperature-sensitive suggesting that the reaction step is rate-controlling. Design a commercial sized fluidized bed reactor (find W) to treat 4 metric tonslhr of solid feed of size R = 0.3 mm to 98% conversion.

26.7. Solve Example 26.3 with the following modification: the kinetics of the reaction is ash diffusion controlled with T(R = 100 ~m=) 1 0 min.

26.8. Repeat Example 26.4 if twice the stoichiometric ratio of gas to solid, still at C,,, is fed to the reactor.

26.9. Repeat Example 26.4 if the gas is assumed to pass in plug flow through the reactor.

To the friendly student tax preparer:

Hi, it’s Shady Slim again. I just got back from my 55th birthday party, and I’m told that you need some more information from me in order to complete my tax return. I’m an open book! I’ll tell you whatever I think you need to know.

Let me tell you a few more things about my life. As you may recall, I am divorced from my wife, Alice. I know that it’s unusual, but I have custody of my son, Shady Jr. The judge owed me a few favors and I really love the kid. He lives with me full time and my wife gets him every other weekend. I pay the vast majority of my son’s expenses. I think Alice should have to pay some child support, but she doesn’t have to pay a dime. The judge didn’t owe me that much, I guess.

I had to move this year after getting my job at Roca Cola. We moved on February 3 of this year, and I worked my job at Roca Cola for the rest of the year. I still live in the same state, but I moved 500 miles away from my old house. I hired a moving company to move our stuff at a cost of $2,300, and I drove Junior in my car. Junior and I got a hotel room along the way that cost us $65 (I love Super 8!).

Can you believe I’m still paying off my student loans, even after 15 years? I paid a total of $900 in interest on my old student loans this year.

Remember when I told you about that guy that hit me with his car? I had a bunch of medical expenses that were not reimbursed by the lawsuit or by my insurance. I incurred a total of $20,000 in medical expenses, and I was only reimbursed for $11,000. Good thing I can write off medical expenses, right?

I contributed a lot of money to charity this year (and have receipt documentation for all contributions). I’m such a nice guy! I gave $1,000 in cash to the March of Dimes. I contributed some of my old furniture to the church. It was some good stuff! I contributed a red velvet couch and my old recliner. The furniture is considered vintage and is worth $5,000 today (the appraiser surprised me!), even though I only paid $1,000 for it back in the day. When I contributed the furniture, the pastor said he didn’t like the fabric and was going to sell the furniture to pay for some more pews in the church. Oh well, some people just have no taste, right? Roca Cola had a charity drive for the United Way this year and I contributed $90. Turns out, I don’t even miss it because Roca Cola takes it right off my paycheck every month . . . $15 a month starting in July. My pay stub verifies that I contributed the $90 to the United Way. Oh, one other bit of charity from me this year. An old buddy of mine was down on his luck. He lost his job and his house. I gave him $500 to help him out.

I paid a lot of money in interest this year. I paid a total of $950 in personal credit card interest. I also paid $18,000 in interest on my $500,000 home mortgage that helped me buy my dream home. I also paid $2,000 in real estate taxes for my new house.

A few other things I want to tell you about this year. Someone broke into my house and stole my kid’s brand-new bicycle and my set of golf clubs. The total loss from theft was $900. I paid $125 in union dues this year. I had to pay $1,200 for new suits for my job. Roca Cola requires its managers to wear suits every day on the job. I spent a total of $1,300 to pay for gas to commute to my job this year.

Oh, this is pretty cool. I’ve always wanted to be a firefighter. I spent $1,400 in tuition to go to the local firefighter’s school. I did this because someone told me that I can deduct the tuition as an itemized deduction, so the money would be coming back to me. That should be all the information you need right now.

Please calculate my taxable income and complete page 1 of Form 1040 (through taxable income, line 11b) and Schedule A.
