Answer:
His overal final score is 81.2. His letter grade is a B.
Step-by-step explanation:
Weighed average:
The sum of all values multiplied by it's weight. The weight is a proportion(a value between 0 and 1).
So.
Score of 72 on the midterm, which counts 5%.
Score of 83 on the project score, which counts 25%.
Score of 91 on homework assignments, which counts 35%.
Score of 74 on the final exam, which counts 35%.
His grade is:
G = 72*0.05 + 83*0.25 + 91*0.35 + 74*0.35 = 82.1.
His overal final score is 81.2.
At least 80 but less than 90 is a B
So his letter grade is a B.
Divide both sides by 
:
If 
, then
and more generally, for any integer 
,
The answer is y = -x + 11
1) Divide the numbers
6/22= 0.27 (27 is repeating)
2) Multiply the decimal by 100
0.2727(100)= 27.27
3) Round
27.27 is closer to 27
<u><em>Therefore, 6/22 to the nearest whole number is 27%.</em></u>
Hopefully this helps!
