You also learn in class that one kilobyte of computer memory will hold about 2/3 of a page of typical text (without formatting).

Travka [436]

Answer:

The flashdrive can hold 35389 400-pages-books

Explanation:

If $\frac{2}{3}$ of a page occupies 1 kB of memory, we can calculate how much memory a book will take

$2/3kB=1 page\\ x kB=400 pages\\266.67 kB=400 pages$

Now that we know that a book average file size is about 266,67 kB, we calculate how many of them can a 9 GB flash drive hold.

To do the calculation, we have to know how many kilobytes are in 9 gigabytes.

There is 1024 kilobytes in a megabyte, and 1024 megabytes in a gigabyte, so:

$Memory_{in _kilobytes}^{} =1024\frac{kilobytes}{megabytes} *1024\frac{megabytes}{gigabytes}*9=9437184 kilobytes$

Finally, knowing the average file size of a book and how much memory in kilobytes the 9 GB flash drive holds, we calculate how many books can it hold.

$Books=\frac{Flash drive memory}{Filesize of a book} =\frac{9437184kilobytes}{266.67\frac{kilobytes}{book} } =35389,4 books$

The flashdrive can hold 35389 400-pages-books, or 14155776 pages of typical text.

Answer:

The correct answer is "Consistency".

Write a program that would determine the day number in a non-leap year. For example, in a non-leap year, the day number for Dec

SOVA2 [1]

Answer:

In Python:

months = ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]

daymonths = [31,28,31,30,31,30,31,31,30,31,30,31]

day = int(input("Day: "))

month = input("Month: ")

ind = months.index(month)

numday = 0

for i in range(ind):

numday+=daymonths[i]

numday+=day

print(numday)

Explanation:

This initializes the months to a list

months = ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]

This initializes the corresponding days of each month to a list

daymonths = [31,28,31,30,31,30,31,31,30,31,30,31]

This gets the day from the user

day = int(input("Day: "))

This gets the month from the user

month = input("Month: ")

This gets the index of the month entered by the user

ind = months.index(month)

This initializes the sum of days to 0

numday = 0

This adds up the days of the months before the month entered by the user

for i in range(ind):

numday+=daymonths[i]

This adds the day number to the sum of the months

numday+=day

This prints the required number of days

print(numday)

Note that: Error checking is not done in this program
