A contractor orders, say, 30 cubic yards of premixed concrete to construct a patio that is to be, say, four inches thick. The length of the patio is to be, say, twice the width. Write a program that prompts the user to specify the amount of premixed concrete (in cubic yards) ordered, the thickness of the patio (in inches), and the ratio of length and width. The program then outputs the length and width of the patio (in feet). (1 cubic yard 5 27 cubic feet.) (To find the square root of a decimal number, include the header file cmath using the statement #include <cmath>, in your program. The function sqrt, included in this header file, determines the square root of a decimal number. For example, sqrt(16.0) = 4.0.)

The cost of renting a room at a hotel is, say $100.00 per night. For special occasions, such as a wedding or conference, the hotel offers a special discount as follows: If the number of rooms booked at least 10, the discount is 10%; at least 20, the discount is 20%; and at least 30, the discount is 30%. Also if rooms are booked for at least three days, then there is an additional 5% discount. Write a program that prompts the user to enter the cost of renting one room, the number of rooms booked, the number of days the rooms are booked, and the sales tax (as a percent). The program outputs the cost of renting one room, the discount on each room as a percent, the number of rooms booked, the number of days the rooms are booked, the total cost of the rooms, the sales tax, and the total billing amount. Your program must use appropriate named constants to store special values such as various discounts.
A contractor orders, say, 30 cubic yards of premixed concrete to construct a patio that is to be, say, four inches thick. The length of the patio is to be, say, twice the width. Write a program that prompts the user to specify: 1. The amount of premixed concrete (in cubic yards) ordered 2. The thickness of the patio (in inches) 3. The ratio of length and width o Ex. If the ratio is 3 to 2, have the program accept a 3 then a 2. Then compute the ratio using these numbers The program then outputs: 1. The length and width of the patio (in feet). (1 cubic yard = 27 cubic feet.) To calculate the width, you will need to: 1. Find the total cubic feet of the concrete 2. Divide the total cubic feet of concrete by the result of the length to width ratio multiplied by the thickness of the patio, over 12 (inches in a foot) 3. Square root the answer To find the square root of a decimal number, include the header file cmath using the statement #include , in your program. The function sqrt, included…
Airline companies apply baggage restrictions for their passengers. An airline company has decided to apply a 10kg limitation for passengers' hand luggage and 20kg for their normal baggage. When passengers arrive, they enter their hand and normal luggage weight from the keyboard. If passengers exceed their normal baggage allowance of 10 dollars per gram, they pay 12 dollars per kg. Accordingly, write the program that calculates the baggage price of the airline they will go to according to the baggage values entered by the arriving passenger and keeps this from closing the program for each passenger. Note: If hand and normal baggage allowances are stretched below the maximum value, the payment amount will be considered not negative. An example printout is given on the right. Geri bildirim gönder
A milk carton can hold 3.78 liters of milk. Each morning, a dairy farm ships cartons of milk to a local grocery store. The cost of producing one liter of milk is $0.38, and the profits of each carton of milk is $0.27. Write a program that does the following: a. Prompts the user to enter the total amount of milk produced in the morning. b. Outputs the number of milk cartons needed to hold milk. (round your answer to the nearest integer) c. Outputs the cost of producing milk. d. Outputs the profit for producing milk. Additional Requirements: a. The following values must be declared as named constants: The carton capacity: 3.78 The cost of one liter: 0.38 The profit on a carton: 0.27 b. Use meaningful variable and constant names c. Format any dollar amount output to two decimal places

A bag of biscuit can hold 22 biscuit, and a container can hold 70 bags of biscuit. Write a program that prompts the user to enter the total number of biscuits, the number of biscuit in a bag, and the number of biscuit bags in a container. The program then outputs the number of bags and the number of containers to ship the biscuit. Note that each bag must contain the specified number of biscuit, and each container must contain the specified number of bags. If the last bag of biscuit contains less than the number of specified biscuit, you can discard it and output the number of leftover biscuit. Similarly, if the last container contains less than the number of specified bags, you can discard it and output the number of leftover bags. Use C++ program.

Write the program that computes an employees pay. The program should input the number of hours worked in a week and the pay rate per hour. Any hours that are over 40 and less than or equal to 50 will be computed using (1.5 * payrate). Any hours over 50 will be computed using ( 2 * payrate). The output of the program should be regular pay, overtime pay, double pay and total pay. Regular pay is the pay received for the first 40 hours. Total pay is regular pay plus overtime pay plus the double pay. For this assignment use (if-else). Format your output so it looks nice.

The length of the yard.b. The radius of a fully grown tree.c. The required space between fully grown trees.The program outputs the number of trees that can be planted in the yard and the total space that will be occupied by the fully grown trees.
For each used car a salesperson sells, the commission is paid as follows: $20 plus 30% of the selling price in excess of the cost of the car. Typically, the minimum selling price of the car is the cost of the car plus $200 and the maximum selling price is the cost of the car and $2,000. Write a program that prompts the user to enter the salesperson’s fixed commission, the percentage of the commission, the purchasing cost of the car, the minimum and maximum amount to be added to the purchasing cost to determine the minimum and maximum selling price, and outputs minimum and maximum selling price of the car and the salesperson’s commission range.
