Answer:
11/15 or .733
Step-by-step explanation:
What you need to do is minus the two fraction problems.
5/6-1/10. You need to make it where they have the same denominator.
25/30-3/30=22/30=11/15=.733.
11/15 or .733 is your answer.
C is the right answer. 54% is roughly half of the number. Just divide 168 by 2 ans you will have an estimation of your answer
A=3
b=-6
c=1
x=(-b±<span>√(b^2-4ac))/2a
x=(6</span>±√(36-12))/(6)
x=(6±√(24))/(6)
x=(6±2√(6))/(6)
x=(3±√(6))/(3)
x≈1.82
x≈<span>.184</span>
Answer: Time spent on Question C=3 9/10
Step-by-step explanation:
Total Time to do the entire quiz= 20 minutes
Time spent on Question A=10 7 /10 minutes
Time spent on Question B=5 2/ 5 minutes
Time spent on Question C=Total Time to do the entire quiz-(Time spent on Question A+Time spent on Question B)
20mins- (10 7 /10 +5 2/ 5)
20mins - ( 15 7+4 /10)
20mins - ( 15 11/10=16 1/10))
20mins -16 1/10
19 10/10 -16 1/10
Therefore Time spent on Question C= 3 9/10
