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.

Answer:
1,232 ft/min (feet per minute)
Step-by-step explanation:
14 miles = 73,920 feet
1 hour = 60 minutes
73, 920 / 60 = 1,232 feet/minute
Okay, the two values you've got is 2 2/3 and 1 1/4.
Convert both of those values into improper fractions, which is 2 2/3 = 8/3 and
1 1/4 = 5/4
Now, subtract those two values: 8/3 - 5/4, find the lowest common denominator, which is 3*4 = 12...
8/3 - 5/4 = (8*4 - 5*3)/12 = (32 - 15)/12 = 17/12 = 1 5/12
