Solution :
It is given that :
The digits 0 through 9 in hexadecimal have their usual meanings. But letters A through F function like the digits and it means digits 10 through 15, respectively.
Now the base of a hexadecimal is 16.
Now we know from 0 to 9 [tex]$\rightarrow$[/tex] A, B, C, D, E, F
Now the maximum two digits hexadecimal numbers are = F F
So, F F [tex]$= 16 \times 15 + 16^0 \times 15$[/tex]
= 255

if 100 KB file is stored in 2 MB folder how many files can be stored in the folder
Answer:
20 files.
Explanation:
Given the following data;
Size of file = 100 kilobytes.
Folder size (memory) = 2 megabytes.
Method 1
1000 kilobytes = 1 megabytes.
100 kilobytes = x megabytes
Cross-multiplying, we have;
1000x = 100
x = 100/1000
x = 0.1 mb
Now, to find the number of files that can be stored;
[tex] Number \; of \; files = \frac {Memory}{Size \; of \; each \; file} [/tex]
Substituting into the equation, we have;
[tex] Number \; of \; files = \frac {2}{0.1} [/tex]
Number of files = 20 files.
Method II
We know that;
1 kilobytes = 0.001 megabytes. 100 kilobytes = 0.1 megabytes. 1000 kilobytes = 1 megabytes. 2000 kilobytes = 2 megabytes.Substituting into the formula, we have;
[tex] Number \; of \; files = \frac {Memory}{Size \; of \; each \; file} [/tex]
Substituting into the equation, we have;
[tex] Number \; of \; files = \frac {2000}{100} [/tex]
Number of files = 20 files.
how do i create a a BASIC program to triple the salary of frontline workers?
Answer:
In Latin America and the European Union, for example, 12 and 37 percent of health workers are public sector employees, respectively. Hence wage increases may reduce funding available for other critical medical supplies and equipment, particularly in developing countries with limited fiscal resources. Wage increases for one category of workers, however well justified, can also trigger demands from other workers, particularly in countries with strong trade unions. Temporary salary increases or supplementary payments also tend to become permanent, thereby creating long-term distortions and problems of fiscal sustainability. The first step, then, is to quickly assess the level and structure of health worker compensation to quantify the amount of additional wages that should be paid. Health facility staff consists of frontline medical staff (doctors, nurses, community health workers) as well as non-medical administrative and support staff. In many World Bank client countries, the total gross wages of health workers will consist of:
1.Basic salary. This is based on pay grades in civil service pay laws, or wage legislation for public health workers.
2.Overtime allowance or compensation for overtime work. This is usually in the form of a percentage of basic pay for additional hours worked beyond what is normally specified.
3.Hazard allowance or harmful work conditions allowance. These will be allowances as a percentage of pay for working conditions that are considered risky to the individual.
Other allowances.
4.Other allowances. These typically factor in seniority, additional training, or educational qualifications, as well as working in rural areas or remote locations
5.Performance pay. These are additional payments conditional on either inputs (e.g., working hours), outputs (e.g., patients treated), or outcomes (e.g., patient satisfaction).
6.Per diems or salary supplements. These are usually for attending workshops or training and can be a significant (more than 10 percent) proportion of gross wages.
Cross-national data on health worker wages is very limited. The data that the World Bank has for 10 countries in Latin America and 27 in the European Union shows that while health care workers do enjoy a premium over workers in other sectors of the economy, the premium decreases with country income levels. For countries in the upper income category, they experience a penalty compared to similar workers in lower-income countries (controlling for sex, education, and location). These averages, however, hide variations across different categories of health workers (medical workers represent between 20 and 50 percent of all health care sector workers for countries in Latin America and the European Union).

Temperature converter. This program should prompt the user for two arguments, first a decimal number and second, a single letter, either C or F. The decimal represents a temperature, the character represents which system that degree is in (50.0 F would be 50.0 degrees Fahrenheit etc.). This program should take the given number and convert it to a temperature in the other system. The output string format should be degree(s) is equal to degree(s) . Eg. input 0 C would give the string 0.0000 degree(s) C is equal to 32.0000 degree(s) F. You can assume that either F or C will be given for input, no need to account for invalid input.

Write a recursive method called method3 that accepts an integer parameter and returns the integer reformed by repeating digits 1 and 2. For example, method3 (123456) will return 11223456 repeating only 1 and 2 and method3 (21) will return 2211. If the number is 0, return 0. You may assume that n is not negative
Answer:
Explanation:
The following is written in Java and creates only the method3 and returns a new method after doubling all of the 2's and 1's in the input.
public static int method3(int x) {

playRps – This method plays 24 rounds of rps and returns the total points earned. For each of the 24 rounds, player1’s hand
gesture will be based on calling the nextInt method of the given Random object. If the next integer is even, player1 will play
rock. If it is odd, player1 will play paper. Player1 never plays scissors. Player2 will play rock in the first round, paper in the
second round, scissors in the third round, and repeat the cycle starting with rock again in the fourth round. The method will sum
the return values for the 24 calls to rps and return the total. Note, since an invalid input is never passed in to an rps call using
playRps, your return value should always be a non-negative number.

Write a program that reads an integer, a list of words, and a character. The integer signifies how many words are in the list. The output of the program is every word in the list that contains the character at least once. Assume at least one word in the list will contain the given character.
Ex: If the input is:
4 hello zoo sleep drizzle z
then the output is:
zoo
drizzle
To achieve the above, first read the list into a vector. Keep in mind that the character 'a' is not equal to the character 'A'.

#include
using namespace std;
int main() {
/* Type your code here. */
return 0;

Answer:
In C++:
#include<iostream>
#include<vector>
using namespace std;
int main() {
int len;
cout<<"Length: "; cin>>len;
string inpt;
vector<string> vect;
for(int i =0;i<len;i++){
cin>>inpt;
vect.push_back(inpt); }
char ch;
cout<<"Input char: "; cin>>ch;
for(int i =0;i<len;i++){
size_t found = vect.at(i).find(ch);
if (found != string::npos){
cout<<vect.at(i)<<" ";
i++;
}
}
return 0;
}
Explanation:
This declares the length of vector as integer
int len;
This prompts the user for length
cout<<"Length: "; cin>>len;
This declares input as string
string inpt;
This declares string vector
vector<string> vect;
The following iteration gets input into the vector
for(int i =0;i<len;i++){
cin>>inpt;
vect.push_back(inpt); }
This declares ch as character
char ch;
This prompts the user for character
cout<<"Input char: "; cin>>ch;
The following iterates through the vector
for(int i =0;i<len;i++){
This checks if vector element contains the character
size_t found = vect.at(i).find(ch);
If found:
if (found != string::npos){
Print out the vector element
cout<<vect.at(i)<<" ";
And move to the next vector element

What were Roman Capitals first used for?
Answer:
Square capitals were used to write inscriptions, and less often to supplement everyday handwriting. When written in documents this style is known as Latin book hand. For everyday writing the Romans used a current cursive hand known as Latin cursive. Notable examples of square capitals used for inscriptions are found on the Roman Pantheon, Trajan's Column, and the Arch of Titus, all in Rome. Square capitals are characterized by sharp, straight lines, supple curves, thick and thin strokes, angled stressing and incised serifs. These Roman capitals are also called majuscules, as a counterpart to minuscule letters such as Merovingian and Carolingian.
8.11 LAB: Count characters - functions Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. Ex: If the input is: n Monday, the output is: 1 Ex: If the input is: z Today is Monday, the output is: 0 Ex: If the input is: n It's a sunny day, the output is: 2 Case matters. n is different than N. Ex: If the input is: n Nobody, the output is: 0 Your program must define and call the following function that returns the number of times the input character appears in the input string. int CountCharacters(char userChar, const string
Answer:
#include<iostream>
using namespace std;
int CountCharacters(char userChar, const string inputstr){
int k = 0;
int iter = 0;
for (iter = 0; iter < inputstr.size(); iter++){
if (inputstr[iter] == userChar){
++k; }}
return k;}
int main(){
string str;
char userChar[1];
cout<<"Char: "; cin>>userChar;
cin.ignore();
cout<<"String: "; getline(cin, str);
cout<<CountCharacters(userChar[0],str);
return 0;}
Explanation:
Written in C++:
The function is defined here:
int CountCharacters(char userChar, const string inputstr){
This initializes a count variable k to 0
int k = 0;
This initializes an iterating variable iter to 0
int iter = 0;
This iterates through the characters of the string being passed to the function
for (iter = 0; iter < inputstr.size(); iter++){
This checks for matching characters
if (inputstr[iter] == userChar){
If found, k is incremented by 1
++k; }}
This returns the total count
return k;}
The main begins here
int main(){
This declares a string variable
string str;
This declares a character variable
char userChar[1];
This gets input for the character variable
cout<<"Char: "; cin>>userChar;
This lets the user get another input
cin.ignore();
This gets input for the string variable
cout<<"String: "; getline(cin, str);
This calls the function and return the count of character in the string
cout<<CountCharacters(userChar[0],str);
Given the mass of an airplane, the amount of forward force produced by its propellers, and the mass of the TWO gliders it is towing (airplane connected to first glider and the first glider is connected to the second glider), calculate the resulting tension on each cable connecting the aircraft and the acceleration of the glider. Vertical forces and air resistance are not considered. . Your program must accept input and produce output that matches exactly to the given executions. Note that the width modifier used for the tension values is calculated as the number of digits in the force input plus six. Example Execution #1 (eleven spaces after colon character for tension output): Enter mass of airplane (kg) -> 15000 Enter mass of glider #1 (kg) -> 5000 Enter mass of glider #2 (kg) -> 4500 Enter force produced by propellers (N) -> 75000 Acceleration: 3.06 m/s^2 -=-=-= Resulting tension on cable #1: Resulting tension on cable #2: 29081.63 Newtons 13775.51 Newtons
Answer:
Follows are the code to this question:
#include <stdio.h>//header file
int main() //main method
{
int plane, g1, g2, f;//defining integer variables
float m,a,t1,t2; //defining float variables
printf("Enter mass of airplane (kg)-> ");//print message for input value
scanf("%d", &plane);//input value
printf("Enter mass of glider #1 (kg)-> ");//print message for input value
scanf("%d", &g1);//input value
printf("Enter mass of glider #2 (kg)-> ");//print message for input value
scanf("%d", &g2);//input value
printf("Enter force produced by propellers (N) -> ");//print message for input value
scanf("%d", &f);//input value
m= plane + g1 + g2;//use float variable m to calculate Mass
a=f/m;//use float variable a to calculate Acceleration
printf("\nAcceleration: %.2f m/s^2", a);
printf("\n-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-");//use print method for design
t1 = (g1 + g2) * a;//using the t1 variable to calculate tensions
printf("\nResulting tension on cable #1: %.2f Newtons", t1);//print tension value
t2 = g2 * a;//using the t1 variable to calculate tensions
printf("\nResulting tension on cable #2: %.2f Newtons", t2);//print tension value
printf("\n-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-");//use print method for design
return 0;
}
Output:
Please find the attached file.
Explanation:
In this code four integer variable "plane, g1, g2, and f" and four floating-point variables "m, a, t1, and t2" is declared, in which the integer variable is used for input the value from the user-end.
In the next step, the "m" variable is used, which adds the "plane, g1, and g2" integer value to calculate mass, and in the "a" variable it calculates the acceleration, and in the "t1 and t2" variable it calculates the tension and prints its value.

I added a second attachment which illustrates the movement
function (solveMaze) {
moveForward(); ---- The robot moves up (to position 1)
moveForward(); ---- The robot moves up (to position 2)
rotateRight(); ---- The robot changes where it faces (however, it is still at position 2)
while(canMove("forward")) { moveForward(); } ---- This is repeated until the robot reaches the end of the grid (i.e. position 3 and 4)
rotateLeft(); ---- The robot changes where it faces (however, it is still at position 4)
moveForward(); ---- The robot moves up to the gray square
