1. Check out this Krazy Pic from the 10/29 mailing. Why do we know this picture probably came from Great Britain, say, rather than the US? (I just noticed there is ALSO another subtle semi-clue – anyone catch it?)
2. Check out this riddle. Interesting, and ‘outside the box’. (I’d probably change the question to ‘of the four names here, which is most likely . . .’, but hey.)
Here (#3 & #4) are a couple of almost-repeats from three years ago (October, 2015):
3. J.J.J. Smith has an 85 average on his four tests in Calculus. The final is the same weight as each test – all are 100 points. What will he need to score on the final, to bring his grade up to an A (90 average)?
4. If you write down every whole number (integer) between 500 and 700, how many times will you write the digit 6?
5. I’m Rodney and I live on a farm. With me are 4 other dogs named Brownie, Spot, Fido, and Blackie. There is a fifth dog – what is it’s name?
6. Ralph went for 5 days without sleep. He felt and acted perfectly normal. Why is that?
7. How is your mother’s sister’s brother in law related to you?
8. Always, sometimes, or never? A) A right triangle has an acute angle. B) A right triangle has an obtuse angle.
9. Always, sometimes, or never: A) The radius of a circle is longer than the diameter. B) A triangle with 2 equal sides is equilateral.
10. If p is a prime and 2p – 1 is also prime, then 2p – 1 is called a Mersenne Prime. Find the three smallest Mersenne primes.
11. I am divisible by 5 and I am odd. I have less than 4 digits, but am greater than 12 x 12. The sum of my digits is a square and their product is 15. What number am I?
12. Find the area and perimeter of a right triangle with legs of 4 & 5.
