Elza [17]

Answer:

Python code is given below with appropriate comments

Explanation:

#Prompt the user to enter the test score and class rank.

testScore = input()

classRank = input()

#Convert test score and class rank to the integer values.

testScore = int(testScore)

classRank = int(classRank)

#If the test score is greater than or equal to 90.

if(testScore >= 90):

#If the class rank is greater than or equal to 25,

#then print accept message.

if(classRank >= 25):

print("Accept")

#Otherwise, display reject message.

else:

print("Reject")

#Otherwise,

else:

#If the test score is greater than or equal to 80.

if(testScore >= 80):

#If class rank is greater than or equal to 50,

#then display accept message.

if(classRank >= 50):

print("Accept")

#Otherwise, display reject message.

else:

print("Reject")

#Otherwise,

else:

#If the test score is greater than or equal to

In a particular jurisdiction, taxi fares consist of a base fare of $4.00, plus $0.25 for every 140 meters traveled. Write a func

devlian [24]

Answer:

// here is code in java.

import java.util.*;

// class definition

class Main

{

// method that return total fare

public static double fare(double dis)

{

// calculate the total fare

double tot_fare=(4+((dis*1000)/140)*0.25);

return the fare

return tot_fare;

}

//driver method

public static void main (String[] args) throws java.lang.Exception

{

try{

// scanner object to read input string

Scanner s=new Scanner(System.in);

// variable

double dis;

System.out.print("please enter the distance in KM: ");

//read the number

dis=s.nextDouble();

// call the function with "dis" parameter

double ride_fare=fare(dis);

// print the total fare

System.out.println("total fare is: "+ride_fare);

}catch(Exception ex){

return;}

}

Explanation:

Read the distance from user with the help of scanner class.Call the function with parameter "dis".Here it will calculate the total fare as (4+((dis*1000)/140)*0.25). Here base fare is $4 and $0.25 for every 140 meter.Then function will return the total fare.

Output:

please enter the distance in KM: 7

total fare is: 16.5
