Step 1: First, consider the sublist [18, 13]. Divide the first number in this list i. e. 18 by the second number in this list i. e. 13 using list indexing method. Step 2: Next, consider the second sublist [4, 5]. Divide the first number in this list i. e. 4 by the second number in this list i. e. 5 using list indexing method. There can be more than two sublists. So, perform Step 1 and Step 2 using for loop.

Step 3: Calculate the sum of fractions by adding the results obtained in Step 1 and Step 2.

Step 4: Round off the result to the nearest whole number using the round() function. The syntax of round() function is:

Syntax: round(float_num, num_of_decimals)
i dont get this please help!!!

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."

Take a critical look at three gui applications you have used—for example, a spreadsheet, a word-processing program, and a game. describe how well each conforms to the gui design guidelines listed in this chapter.

Create a program that will take in a single x and y coordinate as the origin. after the input is provided, the output should be all of the coordinates (all 26 coordinates read from the “coordinates.json” file), in order of closest-to-farthest from the origin.
