The diagonal's length is about 3.5 inches; to solve, use the Pythagorean theorem (a^2 + b^2 = c^) to determine the length of the diagonal using one of the two triangles it forms by cutting the square in half. One triangle has three sides: 6 in, 6 in, and the unknown diagonal. 6^2 + 6^2 = c^2 Plug in the known sides 36 + 36 = c^2 Simplify 72 = c^2 Simplify ~3.5 = c Take the square root of both sides
First we divide 11.25/3.75=3 so we would know how many 3/4 pounds are there. Then, we know there are 3-3/4 pounds of walnuts. Mulitply them, you will get 9/4
10lb. of jam needs 5lb. apple, or 2lb. of jam needs 1lb. apple. Now we want 8lb. of jam. Set up a proportion: 2/1=8/x Solve for x by cross-multiplying. 2x=8 x=4 lb. of apple
