The reaction between solid white phosphorus and oxygen produces solid tetraphosphorus decoxide.

Solve the system of equations. \begin{aligned} &-6y+11x = -36 \\\\ &-4y+7x=-24 \end{aligned} −6y+11x=−36 −4y+

lesya [120]

-6y + 11x = -36....multiply by 4
-4y + 7x = -24....multiply by -6
-----------------
-24y + 44x = - 144 (result of multiplying by 4)
24y - 42x = 144 (result of multiplying by -6)
----------------add
2x = 0
x = 0

-4y + 7x = -24
-4y + 7(0) = -24
-4y = -24
y = -24/-4
y = 6

solution is (0,6)

<h3>Laws of new york factory investigating commission </h3>

The background of this question is that in 1911 right in New York City, there was a ghastly fire incident at a factory that prompted the factory commission to generate some reforms as regards the safety and health of the workers. Furthermore, a special commission was mandated to carry out a thorough investigation on the working conditions that were prevalent in a large number of the industries.

Lastly after the thorough investigation, the commission submitted 17 bills, out of which 13 of them became law. Among this bill, the measures that pertained to factory safety and health laws, included; "better fire safety efforts, more adequate air-conditioning system and factory ventilation, improved sanitation and others."

The options are missing and they are;

A: no factory workers under age ten

2.17 LAB: Word frequencies - methods Write a program that reads a list of words. Then, the program outputs those words and their

pickupchik [31]

Using the knowledge in computational language in JAVA it is possible to write a code that reads a list of words.

<h3>Writting the code in JAVA:</h3>

import java.util.*;

//class name LabClass

public class LabClass{

//function getFrequencyOfWord with array wordList, ListSize and currWord as parameter

public static int getFrequencyOfWord(String[] wordsList, int ListSize, String currWord){

int frequency = 0;

//for loop for iteration

for(int i=0; i<ListSize; i++){

//if current word matches with words present in list

//then increase the frequency by 1

if(wordsList[i].compareTo(currWord)==0){

frequency++;

}

//return frequency at last

return frequency;

}

//main function

public static void main(String[] args) {

//creating object of Scanner class

Scanner sc = new Scanner(System.in);

int size;

//asking user to input size of list

System.out.println("Enter the size of list :");

size = sc.nextInt();

//creating array of same size as user input size

String[] wordList = new String[size];

sc.nextLine();

//asking user to input array elements

System.out.println("Enter list elements one by one :");

for(int i =0; i<size; i++)

{

wordList[i] = sc.nextLine();

}

System.out.print("\n");

sc.close();

//calling function getFrequencyOfWord in every iteration by passing

//required arguments to it

for(int i=0; i<size; i++)

{

String currWord = wordList[i];

int count = getFrequencyOfWord(wordList, size, currWord);

//printing result

System.err.println(currWord + " : " + count);

}

}
