Answer:

128 GB

Explanation:

Here, we are interested in calculating the total capacity of the disk.

From the question, we can identify the following;

Number of surfaces = 4

Tracks per surface = 131,072

Number of sectors = 2,048

Each Block size = 512 bytes

Mathematically;

Total data capacity of the disk = no of tracks * no of sectors * block size

= 131,072 * 2048 * 512 bytes

= 2^17 * 2^11 * 2^9 bytes = 2^37 bytes

1 GB = 2^30 bytes

So 2^37 = 2^7 * 2^30

= 128 GB

True [87]

The program that asks the user how many cookies they want to make and then displays the number of cups of each ingredient is corresponds to the ingredients mentioned above.

<h3>Further explanation</h3>

Python is a general-purpose programming language. We want to write a python program that asks the user how many cookies they want to make and then displays the number of cups of each ingredient.

48 cookies = 1.5 cups of sugar + 1 cup of butter + 2.75 cups of flour, so:

def main():

   cookies = float(input("How many cookies would you like to make?\n>"))

   sugar = (1.5 * cookies) / 48.0

   butter = cookies / 48

   flour = (2.75 * cookies) / 48

   print("To make ", cookies, " cookies, you will need:\n", \

         format(sugar, '.2f'), " cups of sugar\n", \

         format(butter, '.2f'), " cups of butter\n", \

         format(flour, '.2f'), " cups of flour", sep='')

   redoQuery()  

def redoQuery():

   yn = input("Would you like to check another batch size? (y/n)\n>")

   if yn == 'y':

       main()

   elif yn =='n':

       exit()

   else:

       print("Please enter only a lowercase \'y\' or lowercase \'n\'," \

             "then press enter")

       redoQuery()

main()

The run program is shown in the attachment below.
