Write a program. Commence the change to be dispensed from a vending machine. An item machine can cost between $0.25 send a dolla
SSSSS [86.1K]

Answer:

Explanation:

The objective of this question is to write a java program for a vending machine.

/* This program finds out what amount the vending machine is going to dispense. A given item in the machine can cost between $0.25 and a dollar in five-cent increments (25, 30, 35, 40...90, 95 or 100), and the machine accepts only a dollar bill to pay for the item. */

// Compile: javac PP10. java

// Run: java PP10

// imported the scanner class from util package.

import java. util. Scanner;

//class declaration

public class PP10 {

// main method is defined here.

       public static void main(String[]   args)

          {

// declaration of the variables.

             Scanner keyboard=new Scanner (System.in):

//taking the string type input

              int nl, amount, n2, n3, n4, n5;

            System.out.println("Enter price of item (from 20

cents to a dollar, in 5-cents) :");

             n1=keyboard. nextInt ();

            System.out.println("You bought an item for "+n1+"

cents and gave me a dollar");

            System.out.println ("so your change is ");

//the amount is first calculated.

          amount=100-n1;

// quarter value is calculated

            n2=amount/25;

// rest amount is get here.

            amount=amount%25;

// dime value is calculated

             n3-amount/10;

// rest amount is calculated

            amount=amount%10;

// value of nickel is calculated here

            n4=amount/5;

// rest amount is calculated

            amount=amount%5;

//at last the number of pennies is get

            n5=amount;

// Display output

              System. out . println(n2+" quarters") :

              System. out . println(n3+" dimes") ;

              System. out . println(n4+" nickels") ;

              System. out . println(n5+" pennies") ;

       }

  }

Output:

Enter the price of the item (from 20 cents to a dollar, in 5 - cents):

So, you bought an item for $0.45 and gave me one dollar; thus, your change is

2 quarters

0 dimes

1 nickel

0 pennies

6.5 Code Practice: Question 1
vaieri [72.5K]

Answer:

# input the number of temperatures required, which will be 10 here, but the user can print any number.

n=input("Enter the number of temperatures you want")

# create a list which can have n temperatures since it starts from 0, the maximum is n-1, and n needs to be converted to an integer.

temp= [0,int(n)-1]

#declared a variable of float type. As its 0.0 it will be a float, if 0 then integers, and so on

s=0.0

#running a for loop n times, and hence 0 to n-1.

for i in range(0, int(n)):

temp[i]=input("Enter the temperature in degree celsius in float")

s=s + float(temp[i])

i=i+1

print("The sum of the temperatures is:{0:0.1f}", +s)

Explanation:

The question from edhesive is: You need to write a program that calls for ten temperatures and then find the sum of temperatures. The temperature should be in float, which is expected. And the program is as being mentioned in the answer section.

A profit of ₹ 1581 is to be divided amongst three partner P,Q and R in ratio 1/3:1/2:1/5.theshareof R will be?​
Burka [1]

Answer:

R's share = 306

Explanation:

Sum of ratio = 1/3 + 1/2 + 1/5

LCM = 30

Sum of ratio = (10 + 15 + 6) / 30 = 31 /30

Profit to be shared = 1581

P = 1/3 ; Q = 1/2 ; R = 1/5

Share of R :

(Total profit / sum of ratio) * R ratio

[1581 / (31/30)] * 1/5

(1581 / 1 * 30/31) * 1/5

51 * 30 * 1/5

51 * 6 = 306
