Ming made a triangular picture frame out of cardboard. The sides of the frame are 6.75 in., 6.75 in., and 8.375 in. Ming uses the addition below to determine the amount of string she needs to decorate the edges of the frame.675 + 675 + 8.375 = 9.725. The 675 values are lined up with the 375 portion of 8.375.Which explains Ming’s error?She should have included the decimal in 6.75 and aligned the decimal points to add 6.750 + 6.750 + 8.375 = 21.875.She forgot to put the decimal point in two of the numbers: 0.675 + 0.675 + 8.375 = 9.725..She added 6.75 twice, and she should have only added it once: 6.75 + 8.375 = 15.125.She should have placed a zero placeholder after the decimal point to add 6.075 + 6.075 + 8.375 = 20.525.

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
