The Distance Plus partnership has the following capital balances at the beginning of the current year:

Each of the following questions should be viewed independently.

1. If Sergio invests $60,000 in cash in the business for a 20 percent interest, what journal entry is recorded? Assume that the bonus method is used.

2. If Sergio invests $40,000 in cash in the business for a 20 percent interest, what journal entry is recorded? Assume that the bonus method is used.

3. If Sergio invests $50,000 in cash in the business for a 20 percent interest, what journal entry is recorded? Assume that the goodwill method is used.

Note: there is one JE for A to record the admission of new partner under bonus method, one JE for B, to record the admission of new partner under bonus method, and 2 JE's for C, the first to record the entry for goodwill allocation, during the admission of a new partner and the second to record the investment made by the new partner in the business.

1 A buffer is prepared by mixing 50.0 mL of 0.100 M acetic acid with 30.0 mL of 0.100 M sodium hydroxide and 20.0 mL of distilled water. Estimate the concentration of acetic acid in the resulting buffer. Report your answer in moles/liter, but do not include units with your answer. 2 Determine the concentration of acetate ions in the buffer solution. Report your answer in moles per liter, but do not include units in your answer. 3 Estimate the pH of the buffer solution using the Henderson-Hasselbalch equation. 4 Using the Henderson-Hasselbalch equation, estimate the pH of the buffer if an additional 10.0 mL of 0.100 M sodium hydroxide is added. 5 Estimate the pH of the original buffer if 10.0 mL of 0.100 M hydrochloric acid is added.

Discuss property the importance of earnings management, and the role that ethics plays in its reporting. What policies and internal procedures would you consider being the minimum necessary to instill confidence in earnings reports? How and why would you supplement those?

Using c++

Im trying to figure out a good user validation for this loop. So that if a valid number is not input, it gives an error message. I have the error message printing but its creates an infinite loop. Need some help.

double get_fahrenheit(double c){

    double f;

    f = (c * 9.0) / 5.0 + 32;

    return f;  

}

#include "question2.h"

#include<iostream>

#include<string>

using std::cout; using std::cin; using std::string;

int main()

{

    double c;

    double f;

    double user_exit = 444;

    do{

        cout<<"Enter Celsius (Enter 444 to exit)\n";

        cin>>c;

        if(cin.good()){

             f = get_fahrenheit(c);

             cout<<c<<" degrees celsius is "<<f<<" degrees fahrenheit. \n\n";

            break;

        }else {

            cout<<"Invalid Input! Please input a numerical value. \n";

            cin.clear();

        }

    }while(c != user_exit);

Calculate the change in pH when 9.00 mL of 0.100 M HCl(aq) is added to a 100.0 mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq). Calculate the change in pH when 9.00 mL of 0.100 M NaOH(aq) is added to the original buffer system.

The market demand curve for a pair of duopolists is given as P=50- 2Q where Q= Q₁+ Q_2. The constant per unit marginal cost is 7 for firm 1 and 5 for firm 2. Both firms also have no fixed costs. Find the equilibrium price, quantity and profit for each firm if firm 1 is the Stackelberg leader and firm 2 a follower. Now re-do the computations assuming that firm 2 is the leader and firm 1 the follower.

(a) Firm 1 is leader

Equilibrium Price:

Equilibrium Quantity for Firm 1:

Equilibrium Quantity for Firm 2:

Profit for firm 1:
