Answer:
36 boards
Step-by-step explanation:
The boards are as long as the room, so I only had to worry about the width. If the boards were 1/2 ft wide, I would need 2 boards for every foot of width. For 16 ft, I would need 32 boards.
Instead of dividing, I wrote the equivalent multiplication by multiplying by the reciprocal of 11/24 (the reciprocal of 11/24 is 24/11)
I simplified by dividing both 2 and 24 by 2, and both 11 and 33 by 11.
Therefore he needs 36 boards

Answer:
No
Step-by-step explanation:
To make a triangle the angles have to add up to 180 degrees so 90+45+35=170 degrees not 180.
The x axis is the one going this way : ——— the y is the opposite going up so you just have to number it and add the dots
It is just the multiplication of vectors. We'll multiply corresponding pairs together. The general formula for the pairs of (
