an object that weighs exactly one pound is placed on a digital scale that measures weight in ounces. If the scale is precise but not accurate, what weight might shown on the scale?

step-by-step explanation:

12475909

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
