Answer:
0.127 miles ; 5.458 *10^8 miles
Explanation:
Number of bytes needed to store a page = 2000
Number of pages (Harry Potter's book) = 800
Total memory required to store entire book = (2000 * 800) = 1600000 = 16 * 10^5 bytes
Hence,
1 byte of memory will store : (height of each book / memory size of each book)
= 3 ÷ 16 * 10^5
= 1.875 * 10^-6
For 32 bit memory space :
(1.875 * 10^-6 * 2^32) = 8053.06368 inches
1 inch = 1.578 * 10^-5 mile
8053.06368 inches = 8053.06368 * (1.578 * 10^-5) = 0.1270773448704 miles
= 0.127 miles
For 64 bit memory size :
(1.875 * 10^-6 * (2^64)) = 3.45876 * 10^13 inches
(3.45876 * 10^13) * (1.578 * 10^-5)
= 5.458 *10^8 miles
Answer:
The solution code is written in Python:
- sec = int(input("Enter number of seconds: "))
-
- if(sec >=60):
- min = sec // 60
- sec = sec % 60
- else:
- min = 0
-
- print(str(min) + " minutes " + str(sec) + " seconds")
Explanation:
Firstly, use input function to prompt user to enter number of seconds and assign the input value to variable sec (Line 1).
Next, create an if statement to check if the sec is bigger or equal to 60 (Line 3). If so, we user // operator to get minutes and use % operator to get the seconds (Line 4 - 5).
Then we use print function to print the minutes and seconds (Line 9).

Answer:
The program in Java is as follows:
import java.util.Scanner;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
float a, b, c, x, y;
a = input.nextFloat();
b = input.nextFloat();
c = input.nextFloat();
x = input.nextFloat();
y = a * x * x + b * x + c;
System.out.print(y); }}
Explanation:
This declares all variables
float a, b, c, x, y;
The next 4 lines get input for a, b, c and x
<em> a = input.nextFloat();</em>
<em> b = input.nextFloat();</em>
<em> c = input.nextFloat();</em>
<em> x = input.nextFloat();</em>
This calculates the value of y using 

This prints the calculated value of y
System.out.print(y);
