A B D
Step-by-step explanation:
A because it is less than 8.85
B because it naturally falls between 8 and 9
D because 8.8 is larger than 8.6
One square grid has an area of 400.
Another square grid has an area of 256.
The area of the third grid can be:
(squares in third grid) + 256 = 400
OR
256 + 400 = (squares in third grid)
We get this by applying the Pythagorean theorem.
So, the squares in the third grid can either be 144 or 656. And we only have 144 as an option, so that is your answer.
Your final answer is D. 144.
Answer:
The area of the floor equals 229 square feet.
Step-by-step explanation:
The volume of a rectangular storage is given by the area of the floor multiplied by the height of the room. (It follows directly from the formula of a bar.) So the area of the floor is given by the volume of the rectangular storage <em>divided </em>by the height of the room. In symbols: gives . Substituting the given gives that square feet, precisely what we were asked.
