To find one side of a square frame (k x k) you need to find the square root of 55, because this will give you a number that when multiplied by itself, will give you 55. Since it's a square frame the number is the same on the length and the width, so square root works perfectly. Use a calculator to find the square root of 55, the answer is 7.4161984871, in Part A it asks for the whole inch which is no decimals but only whole numbers, so the answer is 7. In Part B it asks to the nearest tenth of an inch, we don't have to round since the hundredth is only 0.01, and so the answer is 7.4.
B. 3. Because if you have two people rolling a six sided die, with odd and even number contributions, you would divide 6 by 2. This is because there are TWO people going for TWO different types of numbers, odd and even. 6/2 gives us 3.
