Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both doubles) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f} {:.2f} {:.2f}'.format(dollars_20_miles, dollars_75_miles, dollars_500_miles)) Ex: If the input is: 20.0 3.1599 the output is: 3.16 11.85 79.00

THIS IS MEANT TO BE IN JAVA So far we've learned variables, branches, loops, and some array. The assignment is: Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both doubles) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:System.out.printf("%.2f", yourValue); The output ends with a newline. This doesn't make sense to me.... Please show the end result and explain why you added what you added. This is what I have so far: import java.util.Scanner; public class LabProgram {public static void main(String[] args) {}}
Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('{:.2f} {:.2f} {:.2f}'.format(your_value1, your_value2, your_value3)) Ex: If the input is: 20.0 3.1599 Then the output is: 3.16 11.85 79.00 Note: Real per-mile cost would also include maintenance and depreciation.
In your favorite open world adventure video game, currency conversion is as given below: 1 Gold coin 23 Bolts 1 Gem 13 Gold coins Write a program that takes a number of Bolts as user input (as an integer) and converts it to the number of whole Gems, Gold coins, and Bolts as shown below. The conversion information between these measurement metrics is provided in the table above. The number of Bolts should be converted in such a way that maximizes the whole number of Gems and Gold coins. Expected output 1 (bold is user input) Enter the number of Bolts: 32 0 Gems(s) 1 Gold coin(s) 9 Bolt(s) Expected output 2 (bold is user input) Enter the number of Bolts: 3000 10 Gem(s) 0 Gold coin(s) 10 Bolt(s) The file should be named as convertCurrency.cpp. Don’t forget to head over to Coderunner on Canvas and paste your solution in the answer box!

Hi, I need help with the following assignment. Implement a program that reads in a year and outputs the approximate value of a Ferrari 250 GTO in that year. Use the following table that describes the estimated value of a GTO at different times since 1962. Year Value 1962-1964 $18,500 1965-1968 $6,000 1969-1971 $12,000 1972-1975 $48,000 1976-1980 $200,000 1981-1985 $650,000 1986-2012 $35,000,000 2013-2014 $52,000,000
Write a program that computes the molecular weight of a carbohydrate (ingrams per mole) based on the number of hydrogen, carbon, and oxygenatoms in the molecule. The program should prompt the user to enter thenumber of hydrogen atoms, the number of carbon atoms, and the numberof oxygen atoms. The program then prints the total combined molecularweight of all the atoms based on these individual atom weights:Atom Weight(grams I mole)H 1.00794c 12.01070 15.9994For example, the molecular weight of water (H20) is: 2(1.00794) +15.9994 = 18.01528.
Suppose you are a cashier at a grocery store and you want to write a program that takes a purchase subtotal and calculates the total purchase cost, including 7% tax.
You are working for a lumber company, and your employer would like a program that calculates the cost of lumber for an order. The company sells pine, fir, cedar, maple, and oak lumber. Lumber is priced by board feet. One board foot equals one square foot that is one inch thick. Theprice per board foot is given in the following table: Pine 0.89Fir 1.09Cedar 2.26Maple 4.50Oak 3.10 The lumber is sold in different dimensions (specified in inches of width and height, and feet of length) that need to be converted to board feet. For example, a 2 x 4 x 8 piece is 2 inches wide, 4 inches high, and 8 feet long, and is equivalent to 5.333 board feet (2 * 4 * 8 = 64, which when divided by 12 = 5.333 board feet). An entry from the user will be in the form of a letter and four integer numbers. The integers are the number of pieces, width, height, and length. The letter will be one of P, F, C, M, O (corresponding to the five kinds of wood) or T, meaning total. When the letter is T, there are no…
CORAL HELP Write a program with total change amount as an integer input, and output the change using the fewest coins, one coin type per line. End each line with a newline. The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Ex: If the input is: 0 or less than 0, the output is: no change Ex: If the input is: 45 the output is: 1 quarter 2 dimes
. Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B and C = 2 D, E and F = 3 G, H and I = 4 J, K and L = 5 M, N and O = 6 P, Q, R and S = 7 T, U and V = 8 W, X, Y and Z = 9 Write a program that asks the user to enter a 10-character number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-GET-FOOD, the application should display 555-438-3663. After displaying the translated telephone number, ask the user if they’d like to enter another number. If the user enters “y”, run the program again. If not, terminate the program. (10 points)Note: the sentence the program reads SHOULD NOT be hardcoded. Allow the user to enter the sentence the program reads PYTHON

C++ In this task, you are required to write a code that converts an Octal number into its equivalent Decimal value or vice versa. The user first selects the conversion choice by inserting 1 or 2. Choice 1 is followed by inserting an Octal integer and getting its Decimal equivalent value as an output. Choice 2 requires inserting a Decimal integer and prints out its Octal equivalent. The Octal numeral system, is the base-8 number system, and uses the digits 0 to 7, that is to say 10 octal represents 8 Decimal and 100 octal represents 64 Decimal. Convertion from an Octal integer into Decimal In the Decimal system, each number is the digit multiplied by 10 to the power of its location (starting from 0). For example: 74 decimal = 7 x 10^1 + 4 x 10^0 1252 decimal = 1 x 10^3 + 2 x 10^2 + 5 x 10^1 + 2 x 10^0 each number is the digit multiplied by 8 to the power of its location (starting from 0). For example: 112 octal = 1 x 8^2 + 1 x 8^1 + 2 x 8^0 Converting an Octal integer into…
