Answer:

5, 10 and 16

Explanation:

The sum of their ages is √961 = 31

If Joe is x years old, the equation that follows is:

x + (x+5) + (x+5+6) = 31

This simplifies to

3x = 31 - 11 - 5 = 15

so x=5

From that you can find

Joe = x = 5

Kate = x+5 = 10

Jody = x+5+6 = 16

olya-2409 [2.1K]

Answer:

A C++ program was used in creating two classes. the code is stated below.

Explanation:

Solution

The C++ program is executed below:

#include<iostream>

using namespace std;

//declare class (will be define later)

class Salesperson;

//class Sale

class Sale

{

  //private members of class

  private:

      string day;

      double amtOfSale;

      int salesPersonId;

 //public methods

  public:

      //constructor that takes day,amount of sale and salesPersonId as parameters

      Sale(string date,double sale,int id)

      {

          //set the private members to the initial values passed

          day=date;

          amtOfSale=sale;

          salesPersonId=id;

      }    

      //declare a friend function that takes objects of the two classes as parameters

      friend void display(Sale,Salesperson);

};  

//define class Salesperson

class Salesperson

{

  //private members of the class

  private:

      int salesPersonId;

      string lastName;    

  //public methods

  public:

      //constructor that takes name and id as parameters

      Salesperson(int id,string name)

      {

          //set the members of the class with the parameters passed

          salesPersonId=id;

          lastName=name;

      }  

      //declare a friend function that takes objects of the two classes as parameters

      friend void display(Sale,Salesperson);

};

//define the friend funtion

void display(Sale saleObj,Salesperson personObj)

{

  //display the sales info using the objects of the two classes

  cout<<"\nSale #"<<saleObj.salesPersonId<<" on "<<saleObj.day<<" for $"<<saleObj.amtOfSale<<" sold by #"<<personObj.salesPersonId<<" "<<personObj.lastName;

}  

int main()

{

  //create object for Sale class and pass default values

  Sale sObj1("12/25/2016",559.95,103);

  //create object for Salesperson class and pass default values

  Salesperson pObj1(103,"Woods");

 

  //create another object for Sale class and pass default values

  Sale sObj2("11/15/2016",359.95,106);

  //create another object for Salesperson class and pass default values

  Salesperson pObj2(106,"Hansen");

  //using the friend function dislay the sales info

  display(sObj1,pObj1);

  display(sObj2,pObj2);

  return 0;

}

Answer:

ooh....

Explanation:

For example, to convert from bar to pounds per square inch you would multiply by 100000 then divide by 6894.757. Or, multiply by 100000/6894.757 = 14.503774. So, to convert directly from bar to pounds per square inch, you multiply by 14.503774.

A bank in your town updates its customers’ accounts at the end of each month. The bank offers two types of accounts: savings and
Lerok [7]

Answer:

This is your corrected code and the output of each test example. I have also added comments with the provided code to make the code understandable. I have also changed itype variable to from int to String in order to print the account type (Savings or Checking) in output.

import java.util.*;

public class bank{  //class name

public static void main (String [] args)  //start of main function body

{int num,error=1; //declare variables

String itype=" "; //stores Checking or Savings account type

char type =0;  //type variable which is one of savings S or checking C

double min,cur =0,balance =0,rate=0;

//declare variables for minimum balance, current balance, interest rate

Scanner in=new Scanner(System.in);

System.out.println("Enter account number: ");  //prompts user to enter acc no

num=in.nextInt();  //reads input account number

while(error==1) {  

//asks user to enter account type C or S

System.out.println("Enter account type(s-savings or c-checking):");

type=in.next().charAt(0);  //reads the input character of account type

if(type=='c'||type=='C')  //if user inputs c or C

{itype= "Checking";  //set itype to Checking when user input c or C

error=0;  //set value of error to 0 means user entered valid type input

rate=3/100.; }  // Savings accounts receives  3% interest

else if(type=='s'||type=='S')  //if user enters S or s that shows Savings account

{itype= "Savings";  //set itype to Savings when user input s or S

error=0;  //set error to 0 means there is no error

rate=4/100.; }  //Savings accounts receives 4% interest

if(error==1)  //in case of error in giving input

System.out.println("Invalid type-re enter"); }  //asks user to input again

System.out.println("Enter minimum balance: ");  //asks user to enter min bal

min=in.nextDouble();  //reads value of input minimum balance

System.out.println("Enter current balance: ");

// reads value of input current balance

cur=in.nextDouble();

balance = cur;  

if(itype=="Checking") //if the account type is checking

{ if(cur>min+5000) //Checking accounts interest is 5%

{rate=5/100.;

cur=cur+rate*cur; //computes new balance

System.out.printf("New balance: $%.2f\n", cur);} //returns new balance value

/*If a customer’s balance falls below the minimum balance, there is a service charge of $25.00 for checking accounts */

else if(cur<min)

{cur-=25;

System.out.printf("New balance: $%.2f\n", cur);} returns the value of new

}

if(itype=="Savings"){ //if account type is Savings

/*If a customer’s balance falls below the minimum balance, there is a service charge of $10.00 for savings accounts */

if(cur<min)

{cur-=10;

System.out.printf("New balance: $%.2f\n", cur);}

else

//Savings accounts receive 4% interest

{cur=cur+rate*cur;

System.out.printf("New balance: $%.2f\n", cur);}}

/* as the program should output account number, account type, current balance, and new balance so i have commented out the extra print statements below */

//System.out.printf("After interest and fees your balance is = $%.2f\n",cur);

System.out.println("Account Number: " + num);

System.out.println("Account type: " + itype);

System.out.printf("Current balance: $%.2f\n ", balance);  //the result is //displayed up to 2 decimal place .2f   } }

Explanation:

Following is the output of each test example:

python A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun
e-lub [12.9K]

Answer:

// program in Python.

#read year

i_year=int(input("Please Enter a year:"))

#check leap year

if((i_year % 4 == 0 and i_year % 100 != 0) or (i_year % 400 == 0)):

   print("{} is a leap year.".format(i_year))

else:

   print("{} is not a leap year.".format(i_year))

Explanation:

Read year from user and assign it to variable "year".If year is completely divisible by 4 and not divisible by 100 or year is completely divisible by 400 then year is leap year otherwise year is not a leap year.

Output:

Please Enter a year:2003                                                                                                          

2003 is not a leap year.
