Because I can take notes from a tablet, and also because I might have bad handwriting. Also because I won't have to carry so much notebooks when I can just carry a tablet.

Write a program that uses nested loops to collect data and calculate the average rainfall over a period of years. The program sh

babunello [35]

Answer:

In Python:

year = int(input("Years: "))

while year<1:

year = int(input("Invalid. Enter 1 or greater: "))

total = 0

for i in range(1,year+1):

for j in range(1,13):

month = int(input("Year "+str(i)+", Month "+str(j)+": "))

while month<0:

month = int(input("Invalid. Enter 0 or greater: "))

total+=month

ave = total/(12*year)

print("Months: "+str(12 * year))

print("Total: "+str(total))

print("Average: "+str(ave))

Explanation:

This gets the number of years

year = int(input("Years: "))

This loop validates the number of years

while year<1:

year = int(input("Invalid. Enter 1 or greater: "))

This initializes total to 0

total = 0

This iterates through the years

for i in range(1,year+1):

This iterates through the month of each year

for j in range(1,13):

This gets the rainfall for each month

month = int(input("Year "+str(i)+", Month "+str(j)+": "))

This loop validates the amount of rainfall

while month<0:

month = int(input("Invalid. Enter 0 or greater: "))

This calculates the total rainfall

total+=month

This calculates the average rainfall

ave = total/(12*year)

This prints the number of month

print("Months: "+str(12 * year))

This prints the calculated total amount of rainfall

print("Total: "+str(total))

This prints the calculated average amount of rainfall

print("Average: "+str(ave))

A disk has 4000 cylinders, each with 8 tracks of 512 blocks. A seek takes 1 msec per cylinder moved. If no attempt is made to pu

shutvik [7]

Answer:

The answer is below

Explanation:

If the blocks of a file are not put together, that is for nonadjacent block of files to each other, the time (t) taken to read a 100 block file is:

t = (average seek + rotational latency + transfer time) * 100 block

Average seek = 5 msec, rotational latency = 10 msec and transfer time = 20 microsec = 0.02 msec

t = (5 + 10 + 0.02) * 100 = 1502 msec

If the blocks of a file are put together, that is for adjacent block of files to each other, the time (t) taken to read a 100 block file is:

t = (seek time * mean interblock distance + rotational latency + transfer time) * 100 block

seek time = 100 microsec = 0.1 msec, rotational latency = 10 msec and transfer time = 20 microsec = 0.02 msec, mean interblock distance = 2 cylinders

t = (0.1*2 + 10 + 0.02) * 100 = 1022 msec

Write a program that asks the user for three strings. Then, print out whether the first string concatenated to the second string

ipn [44]

Answer:

import java.util.Scanner;

public class num5 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter The First String");

String str1 = in.next();

System.out.println("Enter The Second String");

String str2 = in.next();

System.out.println("Enter The Third String");

String str3 = in.next();

String oneAndTwo = str1+str2;

if(str3.equals(oneAndTwo)){

System.out.println(str1+" + "+str2+" is equal to "+str3+"!");

}

else

System.out.println(str1+" + "+str2+" is not equal to "+str3+"!");

}

Explanation:

Implemented in Using Java Programming Language
Import Scanner Class to prompt and receive users' input
Create three string variables and store the three values entered by the user (str1, str2 and str3)
Concatenate str1 and str2 using the + operator and assign to a new variable
Use the if statement with Java's .equals() method to check for equality of the new string with the third string
Print the appropriate message if the equal or not
