Strike441 [17]

Answer:

public class num9 {

   public static void main(String[] args) {

       int sum =0;

       int num =5;

       for(num =5; num<=500; num+=5){

           System.out.println(num);

           sum +=num;

       }

       System.out.println(sum);

   }

}

Explanation:

  • Declare and initialize the variables sum and num
  • Use a for loop with the condition for(num =5; num<=500; num+=5) Since the loop will increment by 5 and run from 5 to 500
  • Within the loop, add num to sum at each iteration
  • Print all elements on seperate lines
  • Outside the loop, print the final value of sum

Utilizando o padrão de medidas e unidades do National Institute of Standards and Technology, em que 1 KB é igual a 1.000 Bytes,
Tanya [424]

Segundo o padrão da  National Institute of Standards and Technology a  alternativa correta é a letra E) 400 músicas.  Segundo o padrão disposto acima, dois Giga Bytes equivalem à dois mil Mega Bytes, assim, se cada música tem exatos 5MB, podemos chegar ao total de músicas que podem ser gravadas em um PenDrive de 2GB livres do seguinte modo :

x=\frac{2000 MB}{5MB};x=400

 A evolução da microeletrônica possibilitou uma capacidade de armazenamento cada vez maior a cada ano. O desenvolvimento de novas tecnologias na área permite também que os produtores possam produzir músicas, fotos e vídeos com cada vez mais qualidade (consequentemente mais pesada).
