Answer:
72%
Step-by-step explanation:
Start by turning both percentages into decimals. To do this take the percent and divide it by 100. So, 60% = 60/100 or .6 and 80% = 80/100 or .8.
Next the student has already completed 20 quizzes. So, 50-20=30 remaining quizzes.
Quizzes already taken:
= 12 passed quizzes.
The remaining quizzes for the school year:
= 24 quizzes
So, Finally add them both together and divide by the total amount of quizzes:
12+24
= 36 passed quizzes
=.72
Now to convert it back into a fraction you multiply the decimal by 100.
= 72%
Answer:

Line up the digits and use traditional algorithm.
Answer:
3^2/15
Step-by-step explanation:
(^5sqrt3^2)^1/3
(3^2/5)^1/3
multiply the powers
3^2/5*1/3
3^2/15
Answer:
C
Step-by-step explanation
Why does C work:
You can calculate the rate of change by subtracting 12 from Distance Traveled = 1, from 12.75 from Distance Traveled = 2 to find the difference of 0.75.
Because the multiple-choice only offers fractions you can check if .75 is correct by converting it into a fraction. This is true, 0.75 is equal to 3/4.
Now that you know the rate of change you need to find the initial value which would be Distance Traveled = 0 and Time = __. To find this you subtract 0.75 from 12 which would give you 11.25.
C. y = 3/4(0.75) + 11.25
A parallelogram has 4 sides.
So, we divide 72, the meters of the parallelogram. = 18
Now, the length is 4 more, so we add. 18+4=22
The length is 22.
Now, both lengths are 22, so double is 44; subtract 44 from 72. 72-44=28
In conclusion, we divided 28 by 2 to get the width of both sides.28/2=14
The width is 14.
