Modify your program from
2. Write a program that asks for the user’s height, weight, and age, and then computes clothing sizes according to the formulas:
■ Hat size = weight in pounds divided by height in inches and all that multiplied by 2.9.
■ Jacket size (chest in inches) = height times weight divided by 288 and then adjusted by adding 1/8 of an inch for each 10 years over age 30. (Note that the adjustment only takes place after a full 10 years. So, there is no adjustment for ages 30 through 39, but 1/8 of an inch is added for age 40.)
■ Waist in inches = weight divided by 5.7 and then adjusted by adding 1/10 of an inch for each 2 years over age 28. (Note that the adjustment only takes place after a full 2 years. So, there is no adjustment for age 29, but 1/10 of an inch is added for age 30.)
Use functions for each calculation. Your program should allow the user to repeat this calculation as often as the user wishes.

Sometimes figuring letter grades is hard. Write a program that asks for, and reads from the user, a midterm exam grade and a final exam grade. Compute the average of those two grades and ouput a letter grade based on the scale shown below. CHALLENGE PROBLEM: One of my graduate school classes modified the above calculation. This professor said that the final grade would be determined by the simple average of the midterm and the final, however, if the student scored better on the final than they did on the midterm, the professor would weight the midterm exam at 25%, and the final exam at 75% when computing the final grade. Modify your code to use this professors modification in determining letter grade. Here is the grading scale:
A supermarket is doing a sales promotion for soft drinks. If one day you buy soft drinks and bring the empty bottles the next day, they exchange each set of K empty bottles for a full one. A customer wants to make the most of this offer and therefore bought several bottles on the first day of the promotion. Now he wants to know how many bottles he will have at the end of the second day of the promotion if he use it to the fullest.
Make a program to calculate this.
Input
The first input line contains integer T (1 ≤ T ≤ 10000), which indicates the number of test cases. In each of the following T lines come two integers N and K (1 ≤ K, N ≤ 10000), respectively the number of soft drinks bought and the number of empty bottles to gain a full.
Output
For each test case print the number of bottles that the customer will have on the second day, if he makes the most of the offer.
Write a python program that computes the zakat, obligatory charity, on camels. The program asks the user to input the number of camels, and then the zakat is calculated based on the following table:
Rule for computing the zakat of 121 camels or more:
You need to find the combinations of 40 camels and 50 camels that will minimize the number of “left over” camels not being “counted” in the zakat. For example, for 130 camels, we have (2*40) + (1*50)=130, with no left overs, and hence, the zakat consists of 2 bint Laboun and 1 Hiqqah. When we have 145 camels, we have the following scenarios: 1. (140) + (250) = 140 with 5 camels left over, 2. (240) + (150) = 130 with 15 camels left over, 3. (340) + (050) = 120 with 25 camels left over. Therefore, in this case the zakat is 1 bint Laboun and 2 Hiqqah, following the first scenario.
Important Notes:
Make sure that the input value is a positive integer. If not, the program must print the following message: Wrong input. Number should be an…

A babysitter charges $10 per hour before noon and $15 after noon. The program reads the starting time in hours and minutes and the ending time in hours and minutes. All times are between 8:00 am, and 7:59 pm, using a 12-hour clock. For example, you should consider hour 8 as 8 am and hour 6 as 6pm. The program should check the validity of the inputs as follows. 1) Hours are from 0-11 (0 for noon). 2) Minutes are from 0-59. 3) The start time must be before noon. 4) The end time must not be before 1pm. The program should display specific warnings regarding the above when the user submits invalid input; the program should prompt the user to re-enter the times again.

- Python For this lab, you will use a tuple to represent a student record. A student record consists of the student’s name, year, and GPA. For example, (“John”, “Senior”, 3.7) is a record for John who is a senior with a 3.7 GPA. You will write a program that prompts the user for the number of records to enter. Then it reads input from the user for each record. Remember that each record consists of a student’s name, year, and GPA. It then prints the record of each student as shown below. Functions: You will write the following functions: read_records(n) Read n number of records and return a list of records. print_records(records) Takes in a list of records and print each one. main() Prompts the user for the number of records to read, get a list of records from the user, and print the records.

- f. A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives.…arrow_forwardWrite a program that begins by reading a number of cents from the users as an integer (this is input from the user).
