Designer Yarn
Posted on Monday, August 16th, 2010 at 7:32 pmCan someone help me on these word problems?
1) The owners of a rectangular swimming pool want to surround the pool with a crushed-stone border of uniform width. They have enough stone to cover 344 square meters. How wide should they make the border?

2)The illustration shows how a geometric wall hanging can be created by stretching yarn from peg to peg across a wooden ring. The relationship between the number of pegs p placed evenly around the ring and the number of yarn segments s that criss-cross the ring is given by the formula below.
s=p(p-3)/2
How many pegs are needed if the designer wants 14 segments to criss-cross the ring? (Hint: Multiply both sides of the equation by 2.)
3) Find x, the height of the landing ramp. (a = 16, b = 20).
