<span>No, it doesn't tessellate because you cannot tile out an area with small decagons.</span>
Answer:
yes because it just reflected, the shape didn't get smaller or bigger. it stayed the same
Let x denote the length of the longer first piece and y the length of the shorter piece.
We have x+y=10 and x=3y-2 hence 3y-2+y=10 => 4y=12 => y=3 => x=7
The shorter piece is 3 feet long
If there are 272.5 rotations in a mile, and 5280 ft in a mile, then there are 5280 ft in 272.5 rotations. Divide 5280 by 272.5 gives us 19.4 ft/rotation.
That's the circumference of the wheel, and since c = πd, 19.4/π = d, d = 6.2 ft. The diameter of the wheel is how tall it is.
Does this help? Any questions?
