What is the true meaning of Christmas?
Answer:
84 is the highest possible course average
Step-by-step explanation:
Total number of examinations = 5
Average = sum of scores in each examination/total number of examinations
Let the score for the last examination be x.
Average = (66+78+94+83+x)/5 = y
5y = 321+x
x = 5y -321
If y = 6, x = 5×6 -321 =-291.the student cannot score -291
If y = 80, x = 5×80 -321 =79.he can still score higher
If If y = 84, x = 5×84 -321 =99.This would be the highest possible course average after the last examination.
If y= 100
The average cannot be 100 as student cannot score 179(maximum score is 100)
Remember, volume is length x width x height. (lxwxh)
5+3 inches is the apparent width. (8)
7+7 inches is the height. (14)
The length is seemingly difficult to solve, but it's easy when you get the hang of it.
You need to divide the toolbox into shapes you can find the volume for and then add it all together.
Let's take 14x5x(7+7). 980.
Now the other half. 16x3x(7+7). 672.
Add.
Volume is 1652 inches.
