Answer:

circ = Circle(100)

circ.set_position(250, 250)

circ.set_color(Color.yellow)

add(circ)

def grow_circle(event):

if event.key == "ArrowLeft":

circ.set_radius(circ.get_radius() - 10)

if event.key == "ArrowRight":

circ.set_radius(circ.get_radius() + 10)

add_key_down_handler(grow_circle)

Explanation:

By making it that when the left/right arrow is clicked the radius of the circle is first taking into account before anything else, then each time the arrow is clicked the current radius either gets 10 added or removed from it.

Problem: Write the Python code of a program called ComputeSquare that asks the user to enter the length of the side of the squar

Lera25 [3.4K]

<h2>Solution :</h2>

The given problem is solved in Python.

def ComputeSquare():

side = float(input('Enter the side of the square: '))

if side > 0:

perimeter = 4 * side

area = side * side

print('Perimeter of the square is:',

perimeter, 'unit.')

print('Area of the square is:', area, 'square unit.')

print('Invalid input.')

ComputeSquare()

<h2>Explanation :-</h2>

In this program, we create a function ComputeSquare() to calculate the perimeter and area of a square.

The function asks the user to enter the side of the square. The side is then stored in a variable.

Now, we check whether the side is greater than 0 or not using if-else statement.

If the condition is true, the perimeter and area is calculated which is displayed using print() statement.

If the condition is false, the else blocks executes printing the error message.

Write a java program that accepts the ingredients for a recipe in cups and converts to ounces

Tanzania [10]

Answer:

Explanation:

public static int cupsToOunces (int cups) {

int ounces = cups * 8;

return ounces;

}

This is a very simple Java method that takes in the number of cups in the recipe as a parameter, converts it to ounces, and then returns the number of ounces. It is very simple since 1 cup is equal to 8 ounces, therefore it simply takes the cups and multiplies it by 8 and saves that value in an int variable called ounces.

Which type of app is the best choice when it is critical to be able to use the device's features but performance is not critical

lisov135 [29]

Answer:

Hybrid.

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem.

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are seven (7) main stages in the creation of a software and these are; planning, analysis, design, development (coding), testing, implementation and execution, and maintenance.

Some of the models used in the software development life cycle (SDLC) are;

I. A waterfall model: it can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.

II. An incremental model: it refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.

III. A spiral model: it can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.

Basically, softwares are categorized into three (3) main categories based on the development platform and these are;

a. Web application.

b. Native application.

c. Hybrid application.

A hybrid application is a type of software application that is designed based on the combination of the elements of both web applications and native applications.

Typically, a hybrid application is a web application that is developed in a native application shell, using a standardized web programming language such as CSS, JavaScript, and HTML.

Generally, a hybrid application avails a programmer the opportunity to write a code for a mobile application once while accommodating or being compatible with multiple app platforms such as Android, Windows, iOS, etc.

Hence, a hybrid application is the best choice of an application when it's critical for the end users to be able to use the features associated with a device such as a mobile phone but performance isn't critical.

Why would you convert your birth year to binary numbers?

I am Lyosha [343]

Answer:

Write out your birthday in the following format: M/DD/YY. For example, if your birthday is on June 11, 2013, it would be written as 6/11/13.

2. Convert the birthday date to binary format. Using our same example from above, 6/11/13 translated into binary code would be: 110/1011/1101.

3. Select one color of bead to represent “0”, a second color to represent “1” and then the third color to represent a space (/) between the numbers.

4. Layout the beads to represent your birthdate in binary code. Don’t forget the third color for the spaces in between the numbers!

5. Once laid out, string all the beads on to the string or pipe cleaner.

6. Tie a knot around the ends and enjoy your one-of-a kind masterpiece as a piece of jewelry or a bag tag….the options are endless!
