Answer: area mean multiply
Step-by-step explanation:
If there are 50 quizzes and the student has taken 20 so far, that means there are 30 remaining quizzes. Now we need to find the overall percentage if the student scores 60% on 20 quizzes and 80% on 30 quizzes.
To do this, we need to figure out what percentage of 50 is 20.
or 40%
If 20 quizzes make up 40% of the total, then the remaining 30 quizzes make up 60%. Now we need to multiply the scores earned by the max possible points out of 100.
0.6(40) + 0.8(60) = 72
The answer is 72%.

Answer:
36 Square Yards
Step-by-step explanation:
The Scale Drawing uses a ratio
2 Inches : 3 Yards
Therefore,
1 Inch = 3/2 Yards
If the area of the scale drawing is 16 Inch²
To get the area of the actual office, we multiply by the square of the scale factor.
Scale Factor=3/2
Therefore:
The area of the actual office space
=16X(3/2)² Square Yards
=36 Square Yards
