fiasKO [112]2 years ago
8 0

Answer:

56 questions.

Step-by-step explanation:

percent got wrong = 100% - percent got correct.

percent got correct = 72%

percent got wrong = 100%-72% = 28% or 0.28

questions got wrong = total questions * percent got wrong.

total questions = 200

questions got wrong = 200*0.28 = 56 questions

Therefore, Sophie got 56 questions wrong.

Hope this helps!

There are many benefits to using folders when working with lots of files.  Here are a few examples:

- You can use folders to sort your files by type, almost like drawers in a desk, so you might have folders for Music, Photographs, Documents, etc.

- You can use folders to group files together into a specific group.  For example in your Photographs folder you might have a folder titled BirthdayPhotographs for all the photographs from your birthday.

- As in the example above you can nest folders to create sub-categories.  Documents might include folders for Homework, Stories, Poems

- Folders can have different permissions applied to them, allowing you to keep personal files in a private folder only you can access, or secret files in a folder that doesn't show up in the normal list of folders!
