How do I convert 29.35 W to J/sec?

How do I convert 312 ft³s^-1mi^-2 to m³ min.^-1km^-2?

How do I convert from 2.2 km/hr to ft sec^-1 and mi² hr^-1?

How do I convert from 5.4 ft sec^-1 to cm sec^-1 and m hr^-1?

Matlab: When I plot "figure (3)", I would like it to produce three lines/curves instead of data points. Currently, the code will only produce a plot when I use characters and symbols. Please help...

1.) An old vial of radioactivee material was found buried in the ground at Hanford Site. in 2014, it was found to contain 0.1578 Ci of 238Pu and 0.1125 Ci of 234U. the vial was labebled year 1951. how many atoms of 238 Pu and 234U were present in the vial in 1951 ?

C++ program, include comments stating what each part of code does please. I want to be able to understand it so I'll be more knowledgeable in the future. The program is multiple files(transcribe_dna_to_rna.h file, transcribe_dna_to_rna.cpp file, main.cpp file and loops_strings_test.cpp). After the directions I also included any starter code or comments left by my professor within the files to aide us.

Directions:

In folder 05_loops_strings write prototype and definition for string value - return function transcribe_dna_into_rna with a string parameter that returns the rna string. Write the required unit test(s) in folder 05_loops_strings_test. Main program flow: No loop. Use the given string as function argument call transcribe_dna_into_rna function and display the output.

data information

NAME:  Hat measurements, including hat size
TYPE:  Observational
SIZE:  26 observations, 6 variables

DESCRIPTIVE ABSTRACT:
 
The dataset contains hat size as well as circumference, length of major axis 
and length of minor axis of the inner hat band for 26 hats. The manufacturer 
and the country of manufacture are also included.

SOURCE:

Katherine Brady and Kari Cornelius, Carleton College ('96) students, gathered 
the observations from hats at a store at the Mall of America in Bloomington, 
Minnesota.

VARIABLE DESCRIPTIONS:

Variables 
1         Hat size
2         Circumference (inches)
3         Length of major axis (inches)
4         Length of minor axis (inches)
5         Where made? Italy = 1, U.S.A. = 2
6         Manufacturer? Beaver = 1, Borsalino = 2, Dobbs = 3, Stetson = 4

please answer the follow question

How many variables are there, and how are they defifined?

• Which variables are quantitative and which are categorical?

• What are the units of measurement for each quantitative variable?

• What questions do you plan to investigate in your project? These may be questions that were of interest

to the researchers who collected data, or they may be questions that you thought of yourself. Make sure to

include questions that you can hope to answer using methods from this course.

The expected pretax return on three stocks is divided between dividends and capital gains in the following way:

a. If each stock is priced at $190, what are the expected net percentage returns on each stock to (i) a pension fund that does not pay taxes, (ii) a corporation paying tax at 21% (the effective tax rate on dividends received by corporations is 6.3%), and (iii) an individual with an effective tax rate of 15% on dividends and 10% on capital gains?

b. Suppose that investors pay 50% tax on dividends and 20% tax on capital gains. If stocks are priced to yield an after-tax return of 8%, what would A, B, and C each sell for? Assume the expected dividend is a level perpetuity.

Importance of Accounting and international business

Write a 250 words post explaining why having an international accounting overview is important. Provide examples.

The following costs result from the production and sale of 4,550 drum sets manufactured by Tight Drums Company for the year ended December 31, 2019. The drum sets sell for $305 each. The company has a 40% income tax rate.

Required:
1. Prepare a contribution margin income statement for the year.
2. Compute its contribution margin per unit and its contribution margin ratio.
3. For each dollar of sales, how much is left to cover fixed costs and contribute to operating income?

If ?H = -60.0kJ and ?S = -0.300kJ/K , the reaction is spontaneous below a certain temperature. Calculate that temperature.

Consider this scenario: You own a small business with 25 employees. In your initial post, explain which internal controls you would use to protect your assets and ensure that your financial statements are accurate.

At a certain temperature, this reaction establishes an equilibrium with the given equilibrium constant, K_c.

3A(g)+2B(g)−⇀↽−4C(g)Kc=2.53×1031

If, at this temperature, 1.70 mol of A and 3.50 mol of B are placed in a 1.00 L container, what are the concentrations of A, B, and C at equilibrium?

Define a class named Payment that contains an instance variable "paymentAmount" (non-static member variable) of type double that stores the amount of the payment and appropriate accessor (getPaymentAmount() ) and mutator methods. Also create a method named paymentDetails that outputs an English sentence to describe the amount of the payment. Override toString() method to call the paymentDetails() method to print the contents of payment amount and any other details not included in paymentDetails().

Define a class named CashPayment that is derived from Payment. This class will have an additional instance variable of type String (a non-static member variable) that specifies a type of currency, such as "dollar", "euro", "peso", "yen", etc. This class should override the paymentDetails method to indicate that the payment is in cash, and the type of currency used. Include appropriate constructor(s)  and accessor/mutator methods for all instance variablesand. Override toString() with contents of cash payment details (should still call paymentDetails()).

Hello folks, i need some JAVA help here.

Define a class named CreditCardPayment that is derived from Payment. This class should contain instance variables (member variables) for the name on the card, expiration date, and credit card number. Include appropriate constructor(s) and accessor/mutator methods for all instance variables. Finally, redefine thepaymentDetails method to include all credit card information in the printout.  Override toString() method with contents of credit payment details (should still call paymentDetails()).

Create a main method within Payment that creates at least two CashPayment and two CreditCardPayment objects with different values and payment amounts. Call toString() methods from each object to print the details of each payment.
