Answer:

The invention of the toothbrush made a huge impact of society and people for many reasons. You should always brush your teeth and keep your mouth clean so you will have nice, white teeth, healthy gums, good breath, and just a clean mouth! Without the toothbrush, your mouth would be smelly, gross, and full of bacteria.Some of the different impact categories included acidification, climate change, eutrophication, human health, land use, resource use and water scarcity. The results concluded that the electric toothbrush had the greatest environmental impact in 15 out of the 16 categories with water scarcity being the exception.Using the electric toothbrush as an example, this article examines the growing acceptability of domestic health technologies that blur the traditional boundaries between health, aesthetics and consumption. By using empirical material from individual and household interviews about people's oral health practices, this research explores the relationships between an everyday artefact, its users and their environments. It investigates the ways in which oral health technologies do, or do not, become domesticated in the home environment. We conclude that the domestication of oral health technologies is not inevitable, with the electric toothbrush often becoming an ‘unstable object' in the domestic setting.

Write a method called classSplit that accepts a file scanner as input. The data in the file represents a series of names and gra

Lelu [443]

Answer:

public static void classSplit(Scanner file){

int studentsOf21 = 0, studentsOf22 = 0,studentsOf23 = 0, studentsOf24 = 0;

while (file.hasNext() == true){

String studentName = file.next();

int year = file.nextInt();

switch (year){

case 2021:

studentsOf21++;

break;

case 2022:

studentsOf22++;

break;

case 2023:

studentsOf23++;

break;

case 2024:

studentsOf24++;

break;

}

int totalGraduate = studentsOf21+studentsOf22+studentsOf23+studentsOf24;

System.out.printf("students in class of 2021: %.2f%n", students2021*100.0/totalGraduate);

System.out.printf("students in class of 2022: %.2f%n", students2022*100.0/totalGraduate);

System.out.printf("students in class of 2023: %.2f%n", students2023*100.0/totalGraduate);

System.out.printf("students in class of 2024: %.2f%n", students2024*100.0/totalGraduate);

}

Explanation:

The classSplit method of the java class accepts a scanner object, split the object by iterating over it to get the text (for names of students) and integer numbers (for graduation year). It does not need a return statement to ask it prints out the percentage of graduates from 2021 to 2024.

class bClass{public:void setX(int a);//Postcondition: x = a;void print() const;private:int x;};class dClass: public bClass{publi

MaRussiya [10]

Answer:

The answer to the given question in the option "a".

Explanation:

In the given c++ program the correct sets value of x and y is option a:

void dClass::setXY(int a, int b) //function implementation

{ //function body.

x = bClass.setX(a); //variable x hold value of setX() function.

b = y; //variable b holds value of y.

}

And other option are not correct that can be described as:

In option b, x is private variable of the base class that is inherit by the derived class but variable y is not part of the base class. that's why it is wrong.
In option c, x= a is correct but y=b is not correct. that's why it is wrong.
In option d we access the value of the private variable x that is a part of the base class but in this we not use any variable that holds its value. that's why it is wrong.

So the answer to this question is the option "a".
