ANSWER IN C++ PLEASE!!!!!
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 by executing
cout << fixed << setprecision(2); once before all other cout statements. Note: End with a newline.
Answer:
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
double mpg, ppg;
cout << "Enter your car's gas mileage (miles/gallon): ";
cin >> mpg;
cout << "Enter the gas price (dollars/gallon): ";
cin >> ppg;
cout << fixed << setprecision(2);
for (int miles : { 20,75,500 }) {
cout << miles << " miles will cost $" << miles * ppg / mpg << endl;
}
}

why should one avoid noise in the computer room
Can you identify one syntax error and one logic error in these lines? How do you think you could avoid making logic errors like the one in this code?
You are creating a program in which the user will input his or her age. The program will calculate the year that the user was born and will then tell the user which decade he or she was born in. Here is part of the code:if year > 1989 and year < 2000 print("You were born in the 1980s")
Answer:
(a) Syntax Error: Missing colon symbol
(b) Logic Error: The condition is wrong
Explanation:
The programming language is not stated; so, the syntax error may not be correctly identified.
Assume the programming language is Python, then the syntax error is the missing colon symbol at the end of the if statement. This is so because, Python required a colon symbol at the end of every if condition statement.
The logic error is also in the condition.
The condition states that all years later than 1989 but earlier than 2000 are 1980s. This is wrong because only years from 1980 to 1989 (inclusive) are regarded as 1980s.

Summary
In this lab, you complete a partially written C++ program that includes a function requiring multiple parameters (arguments). The program prompts the user for two numeric values. Both values should be passed to functions named calculateSum(), calculateDifference(), and calculateProduct(). The functions compute the sum of the two values, the difference between the two values, and the product of the two values. Each function should perform the appropriate computation and display the results. The source code file provided for this lab includes the variable declarations and the input statements. Comments are included in the file to help you write the remainder of the program.

if 209g of ethanol are used up in a combustion process, calculator the volume of oxygen used for the combustion at stp
help plzz
Answer:
a) The volume of oxygen used for combustion at STP is approximately 305 dm³
b) The volume of gas released during combustion at STP is approximately 508 dm³
Explanation:
The given chemical reaction equation for the burning of ethanol in air, is presented as follows;
2CH₃CH₂OH (l) + 6O₂ (g) → 4CO₂ (g) + 6H₂O
The mass of ethanol used up in the combustion process, m = 209 g
The molar mass of ethanol, MM = 46.06844 g/mol∴
The number of moles of ethanol in the reaction, n = m/MM
∴ n = 209 g/(46.06844 g/mol) ≈ 4.537 moles
a) Given that 2 moles of ethanol, CH₃CH₂OH reacts with 6 moles of oxygen gas molecules, O₂, 4.54 moles of ethanol will react with (6/2) × 4.537 = 13.611 moles of oxygen
The volume occupied by one mole os gas at STP = 22.4 dm³
The volume occupied by the 13.611 moles of oxygen gas at STP, 'V', is given as follows;
V = 13.611 mol × 22.4 dm³/mole = 304.8864 dm³ ≈ 305 dm³
The volume occupied by the 13.611 moles of oxygen gas at STP, V = The volume of oxygen used for the combustion ≈ 305 dm³
b) The total number of moles of gases released in the reaction, is given as follows;
The total number of moles = (4.537/2) × (4 + 6) = 22.685 moles of gas
The total volume of gas released, [tex]V_T[/tex] = The volume of gas released during the combustion at STP = 22.685 moles × 22.4 dm³/mole = 508.144 dm³ ≈ 508 dm³

Se le conoce así cuando el analista mismo desarrolla el software necesario para implementar el diseño
Answer:
Desarrollo de software.
Explanation:
El método clásico de desarrollo de software se denomina modelo en cascada, lo que significa que cada fase de desarrollo del programa debe completarse antes de que comience la siguiente, y que se lleva a cabo un extenso trabajo de especificación antes de que comience el desarrollo real del programa. La especificación es tradicionalmente de arriba hacia abajo y el desarrollo se basa en una programación estructurada, es decir, se formula primero un objetivo final para el proyecto, y luego el programa se divide gradualmente en partes funcionales más pequeñas.
Los métodos más nuevos son ágiles y basados en pruebas. Se basan en el desarrollo gradual de muchas entregas parciales del programa y permiten que las distintas fases de desarrollo se lleven a cabo de forma cíclica o en paralelo. Los clientes y usuarios ganan influencia a lo largo del proceso de desarrollo. El desarrollo y las pruebas de prototipos comienzan lo antes posible, antes de que estén listos todos los detalles de la especificación de requisitos. Las decisiones sobre la especificación de requisitos de las versiones de entrega se toman lo más tarde posible, cuando los usuarios han probado y comprendido lo que realmente quieren y existe un buen conocimiento de las necesidades, posibilidades técnicas y dificultades. Cambia entre el método de arriba hacia abajo (para comenzar desde el propósito y el objetivo) y el método de abajo hacia arriba (para comenzar con lo que ya tiene y puede reutilizar, y comenzar con casos especiales simples pero gradualmente hacer que el programa sea cada vez más general).
