Answer:

Just as per cent means out of a hundred, so parts per million or ppm means out of a million. Usually describes the concentration of something in water or soil. One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram soil (mg/kg).

Explain how technology is related to human needs and wants?

Burka [1]

Technology is what makes up the world. It makes life easier, and technology has been around since humans were first evolved. Our questionative behavior is what separates us from other animals. Our need for more is what runs humankind. Using technology to gain more, our kind becomes smarter, which is why we dominate other species. Technology millions of years ago could be a club to kill prey for food, and now, it is how we order essentials. Technology is an easier way to gain something, and since technology is all over the world, humankind will always have their need and want for more.

Create a Card class that represents a playing card. It should have an int instance variable named rank and a char variable named

Helen [10]

Answer:

Explanation:

The following code is written in Java. It creates the Card class and then uses it to create a full house and print out the rank and suit of every card in that hand.

class Card {

int rank;

char suit;

public Card(int rank, char suit) {

this.rank = rank;

this.suit = suit;

}

public int getRank() {

return rank;

}

public char getSuit() {

return suit;

}

class CardTester {

public static void main(String[] args) {

Card card1 = new Card(3, '♥');

Card card2 = new Card(3, '♠');

Card card3 = new Card(3, '♦');

Card card4 = new Card(2, '♦');

Card card5 = new Card(2, '♣');

System.out.println("Card 1: " + card1.getRank() + " of " + card1.getSuit());

System.out.println("Card 2: " + card2.getRank() + " of " + card2.getSuit());

System.out.println("Card 3: " + card3.getRank() + " of " + card3.getSuit());

System.out.println("Card 4: " + card4.getRank() + " of " + card4.getSuit());

System.out.println("Card 5: " + card5.getRank() + " of " + card5.getSuit());

Design a class that has an array of floating-point numbers. The constructor should accept an integer argument and dynamically al

attashe74 [19]

Answer:

See explaination for the code

Explanation:

Here is the code

class NumberArray

{

private:

float *aptr; // Pointer to the array

int arraySize; // Holds the array size

float max,min,avg;

public:

NumberArray(int); // Constructor

~NumberArray(); // Destructor

int size() const // Returns the array size

{ return arraySize; }

void storeNumber(float num,int ele);

float retrieveNumber(int ele);

float getHighest();

float getLowest();

float getAverage();

};

//*******************************************************

// Constructor for IntArray class. Sets the size of the *

// array and allocates memory for it. *

//*******************************************************

NumberArray::NumberArray(int s)

{

arraySize = s;

aptr = new float [s];

for (int count = 0; count < arraySize; count++)

*(aptr + count) = 0;

}

//******************************************************

// Destructor for IntArray class. *

//******************************************************

NumberArray::~NumberArray()

{

if (arraySize > 0)

delete [] aptr;

}

void NumberArray::storeNumber(float num,int ele)

{

if(ele<arraySize)

*(aptr+ele)=num;

}

float NumberArray::retrieveNumber(int ele)

{

return *(aptr+ele);

}

float NumberArray::getHighest()

{

float high=*(aptr+0);

for(int i=1;i<arraySize;i++)

return high;

}

float NumberArray::getLowest()

{

float low=*(aptr+0);

for(int i=1;i<arraySize;i++)

return low;

}

float NumberArray:: getAverage()

{

float ag=0;

alisha [4.7K]

Answer:

To begin, select the shapes you want to format. To select more than one, press and hold the Shift key. When you select one or more shapes, a new Drawing Tools tab appears. Here, you can select Shape Fill to fill the selected shapes with a solid color, gradient, texture, or picture.
