90% x 18 = 16.2
Therefore, you answered about 16 questions correctly out of 18.
Diagram:
M------------O-------------N
................. ^ midpoint
Obviously if O is the *mid*point, then it is exactly halfway between M and N. That also means it has bisected the segment into two equal parts.
On one side you have MO (or OM, if you like)
On the other side you have ON.
In order for O to be the midpoint:
ON = OM
Answer:
B. 9 feet
Step-by-step explanation:
area = side^2
side^2 = 84
side = sqrt(84)
side = 9.2 ft
Each side of a wall measures 9.2 ft.
If you would like to write 0.423 as a percent, you can calculate this using the following step:
0.423 * 100% = 42.3%
The correct result would be 42.3%.
