Read and understand the following problem: 1. Write a program that accepts from the user a weight of an object in kilograms. The program should compute the equivalent weight in grams, milligrams and metric tons. It should display the weight in different units (grams, milligrams and metric tons). Given: 1 metric ton = 1000 kilograms 1 kilogram = 1000 grams 1 gram = 1000 milligrams note: discuss or explain the solution of the problem
C++ Programming Exercise: A real estate office handles, say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say, $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit? Write a program that prompts the user to enter: a. The total number of of units. b. The rent to occupy all the units. c. The increase in rent that results in a vacant unit. d. Amount to maintain a rented unit. The program then outputs the number of units to be rented to maximize the profit.

When you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2/12 = 0.6%. The first months interest on $1,000 is 1000 0.006 = 6. Because the payment is $25 and the interest for the first month is $6, the payment toward the principal amount is 25 6 = 19. This means after making the first payment, the loan amount is 1,000 19 = 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 0.006 = 5.886, that is, approximately $5.89. This implies that the payment toward the principal is 25 5.89 = 19.11 and the remaining balance after the second payment is 981 19.11 = 961.89. This process is repeated until the loan is paid. Write a program that accepts as input the loan amount, the interest rate per year, and the monthly payment. (Enter the interest rate as a percentage. For example, if the interest rate is 7.2% per year, then enter 7.2.) The program then outputs the number of months it would take to repay the loan. (Note that if the monthly payment is less than the first months interest, then after each payment, the loan amount will increase. In this case, the program must warn the borrower that the monthly payment is too low, and with this monthly payment, the loan amount could not be repaid.)
A sphere is characterized by a single dimensions; its radius (r). The surface area of the sphere is calculated as A=4πr2 While the volume is calculated as V=43πr3 Write a program that asks the user for r and when VALID proceeds to calculate both the surface area and the volume of the sphere by calling a single function. The function's prototype is as follows: void sphereCalc(float, float *, float *); All console input and output operations are in main(). Print the area and volyme with 3 decimal places. Follow best programming practices. Use r = 3 for the screenshot. Hint: Define PI using #define PI 3.1415927

write a C++ program. Write a program that calculates and displays the average of a group of test scores, all integers, after the lowest score in the group has been dropped. There are six test scores in the group. The program must contain only the following functions in additionto the main:• void getScore should ask the user for a test score, store it in a referenceparameter variable, and validate it. This function should be called by the mainfunction once for of the six scores to be entered by the user.• double calcAverage should calculate and return the average of the five highest scores. This function should be called just once by the main function, and should be passed the six scores. Use pass by reference to receive the lowest test score.• int findLowest should find and return the lowest of the six scores passed to it. It must be called by the calcAverage function, which uses it to determine which of the six scores to drop.• void displayResults should be called by the main function…
**PLEASE READ THE WHOLE QUESTION!!"" Write a python, program that prints a pyramid made of letters in the middle of the screen. Use functions with parameters for this assignment. The base width of the pyramid is determined by a character the user enters. If the user enters the letter o, the following pyramid will be printed. It can be assumed that the screen width is 80 characters. The following assignments make use of functions with return values ("fruitful functions"). So if the user enters the letter o it will print the ******The input is not always o, the input o is just an example, so the user can enter also a letter like u or w or something else******** **nBesides that the code may not have the charArray = 'abcdefghijklmnopqrstuvwxyz', but it needs to have the range code like (range(97,123)) or something else **
ALL DONE IN PYTHON PLEASE!!!! In many businesses across the country, people are buying food and goods using cash. Whenever a purchase is made with cash, it is usual that change must be back to the customer. Business point of sales software help to ensure that the correct change is return to a customer by providing detailed information of the change that should be returned to the customer. using the fewest number of bills and coins. In this assignment, you are asked to use what we have covered in Modules 1-3 to design and implement a program that writes out what bills (ones, fives, tens, twenties) and coins (pennies, nickels, dimes, and quarters) that should be returned to the customer given two inputs from the user: A total cost of a sale. The amount that was paid by the customer. Ensure that your output is grammatically correct. If the customer does not provide adequate payment, you should print the following statement, the program should end. Did not receive enough cash from the…

1 - Nuclear Power Plant (python) The nuclear powerplant at Threeyedfish will automatically run a program to print a warning message when the reactor core becomes unstable. The warning message reads: NUCLEAR CORE UNSTABLE!!! Quarantine is in effect. Surrounding hamlets will be evacuated. Anti-radiationsuits and iodine pills are mandatory. Since the message contains crucial information, it should be printed three times. To do this, write a function that prints this message. This function has to be used three times.
