3.24 LAB: Exact change Write a program with total change amount as an integer input, and output the change using the fewest coins, one coin type per line. The coin types are Dollars, Quarters, Dimes, Nickels, and Pennies. Use singular and plural coin names as appropriate, like 1 Penny vs. 2 Pennies. Ex: If the input is: 0 (or less than 0), the output is: No change Ex: If the input is: 45 the output is: 1 Quarter 2 Dimes.

3.4 LAB: Seasons Write a program that takes a date as input and outputs the date's season in the northern hemisphere. The input is a string to represent th month and an int to represent the day. Note: End with a newline. Ex: If the input is: April 11 the output is: Spring In addition, check if the string and int are valid (an actual month and day) Ex. If the input is Blue 65 the output is Invalid. The dates for each season in the northern hemisphere are: Spring: March 20-June 20 Summer June 21-September 21 Autumn September 22- December 20 Winter December 21- March 19

PP 6.4 Write a program that prints the first few verses of the traveling song “One Hundred Bottles of Beer." Use a loop such that each iteration prints one verse. Read the number of verses to print from the user. Validate the input. The following are the first two verses of the song: 100 bottles of beer on the wall 100 bottles of beer If one of those bottles should happen to fall 99 bottles of beer on the wall 99 bottles of beer on the wall 99 bottles of beer If one of those bottles should happen to fall 98 bottles of beer on the wall
7. Write a function that evaluates the area of a pentagon. Use "math.pi", for pi, and "math.sqrt" for square root. Write the solution on the space provided below. You do not need to run the code. 311 3.2 (Geometry: area of a pentagon) Write a program that prompts the user to enter the length from the center of a pentagon to a vertex and computes the area of the pen- tagon, as shown in the following figure. The formula for computing the area of a pentagon is Area 3√3 2 -s², where s is TT the length of a side. The side can be computed using the formula s = 2r sin 5' where r is the length from the center of a pentagon to a vertex. Here is a sample run: Enter the length from the center to a vertex: 5.5 Enter The area of the pentagon is 108.61
C Program In order to discourage excess electric consumption, an electrical company charges its customers a lower rate of P75 for the first 250 kilowatt-hours and a higher rate of P8.5 for each additional kilowatt-hour. In addition, a 10% surtax is added to the final bill. Write a program that calculates the electrical bill given the number of kilowatt-hours consumed as input. At the end, print the number of kilowatt-hours consumed and the computed bill.
2.13 LAB: Driving costs Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f} {:.2f} {:.2f}'.format(your_value1, your_value2, your_value3)) Ex: If the input is: 20.0 3.1599 Then the output is: 3.16 11.85 79.00 Note: Real per-mile cost would also include maintenance and depreciation. 318650.2047284.qx3zqy7 LAB 2.13.1: LAB: Driving costs 0/10 ACTIVITY main.py Load default template...

Note: Real per-mile cost would also include maintenance and depreciation 387484.1009620 g3zny7
2.15 LAB: Musical note frequencies On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance (number of keys) from that key, and r is 2(1/12). Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print(f'{your_value1:.2f} {your_value2:.2f} {your_value3:.2f} {your_value4:.2f} {your_value5:.2f}')

10) Write a program that translates a letter grade into a number grade. Letter grades are A, B, C, D, and F, possibly followed by + or -. Their numeric values are 4, 3, 2, 1, and 0. There is no F+ or F-. The symbol + increases the numeric value by 0.3, and the symbol - decreases it by 0.3. For example: Enter a letter grade: B- The numeric value of B- is 2.7.
