ACTIVITY The number of gallons of paint needed to cover a wall is equal to the walls total area divided by 3500. The program reads wall area from input, representing a wall's total area. Complete the program to output the number of gallons of paint needed to cover the wall rounded to five digits after the decimal point Ex 1: If variable wall area is assigned the value 250.0, then the output is: 0.71429 Ex2: If variable wall area is assigned the value 578.6, then the output is 1.65314

Exercise II Write a program that finds the positive integer solutions of the following equation ax³ + bx² + cx' + d = 0. The user enters the values of coefficients a, b, c and d. The program should test each integer starting from -50 to 50, and each time the equation is equal to zero, it prints its value as well as "is a solution". At the end, it displays the total number of positive integers found. Note that if the equation has more than one solution, the plural word “solutions" is used in the output. Sample run 1: Enter the coefficient of a, b, c, d: 1 -8.5 21 -13.5 1 is a solution 3 is a solution The equation has 2 integers as solutions Sample run 2: Enter the coefficient of a, b, c, d: 6 48 103.5 67.5 The equation has no integer solutions Sample run 3: Enter the coefficient of a, b, c, d: 1 -1 -12 0 4 is a solution The equation has 1 integer solution
1- If money is left in a particular bank for more than 5 years, the bank pays interest at a rate of 4.5% of the money; otherwise, the interest rate is 3.0% of the money. Write a program to accept the number of years in the variable numYears and money in the variable money then display the correct interest rate, depending on the value input into numYears 2- Write a program that accepts a user-entered number and calculates the square. Before calculating, check that the number is negative, and isn't zero. If either condition occurs, display a message stating that the operation can't be calculated. 3- Write a program which accept a number of 2 digits and check if ones digit is greater than the tens digit print the number in reverse order, if each of the ones digit and the tens digit greater than 5 print the average of them (ones and tens), otherwise print the message( NOT valid ). 4- Write C++ program to accept a number num (with any number of digits).

Draw a flowchart for a program that: 1) Asks the user to enter from the keyboard electricity consumption in kilowatts (KW) and municipality tax in BD. 2) Calculates the cost of consumed electricity (Elctcost ) as shown in the table below: Consumed electricity (KW)? O to 2000 more than 2000 Elctcost= 0.005xelectricity(KW) 0.020xelectricty(KW) 3) Calculates the monthlyPament(BD) = municipality tax + Elctcost. 4) Displays the value of calculated monthlyPament. %3D

C++ please - 24-hour time (also known in the U.S. as military time) is widely used around the world. Time is expressed as hours since midnight. The day starts at 0000, and ends at 2359. Write a program that converts am/pm time to 24-hour time. If the input is 2:30 pm, the output should be 1430. If the input is 12:01 am, the output should be 0001. Hints: Think of how each hour should be handled. 12:00 am -12:59 am becomes what? 8:00 am becomes what? 12:00 pm? 1:00 pm? Group the hours into cases that should be handled similarly (e.g., 1:00 am to 11:00 am are handled the same). Declare variables for hoursAmPm, minAmPm, and hours24. Note that minutes for 24-hour time remain the same as for am/pm, so no extra variable is needed. Use an if-else statement to detect each case, and set the hours24 appropriately. When outputting hour24, check if the hour is 0-9 (just check for < 10). If so, output a "0". So 7 will be output as 07. Do the same when outputting the minutes. #include…
Completed a partially completed Python program. When completed, the user should be able to enter a year and then press Enter, enter a month and then press Enter, and enter a day and then press Enter to determine if the date is valid. Valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31. Follow these steps for the python program to complete the partially completed program: 1. Write the housekeeping() method that contains input statements to retrieve a year, a month, and a day from the user.2. Add statements to the housekeeping() method that convert the string representation of the year, month, and day to ints.3. Include the output statements in the simulated endOfJob() method. The format of the output is as follows:month/day/year is a valid date.ormonth/day/year is an invalid date.
3. The formula for determining compound interest is: A represents the amount to earn; P is the principle that is initially invested; r is the interest rate earned; n is the number of times the interest is compounded; and t is the number of time periods for the investment. Write a program that prompts the user to enter P, r, n and t. The program should output the amount earned on the investment. 4. Look up the Pythagorean theorem if you are not already familiar with it. Use the following formula to solve for c in the formula: c = √a2 + b2. Use the proper functions from the cmath header file. Be sure to output the result.l
