Double the time to work on these!! You can submit answers (for recognition) until NOON on Thursday, 11/20. Use a Contact Form, or see below for more options.
1. CELEBRATE on Thursday!! 🙂 This past Thursday, (11/13) was one of only THREE (3) Twin Prime Days* in any year. What are the other two twin prime days each year?
* Perhaps you will recall (from the 10/27 Weekly Sharing feature on them?) that twin primes are primes that are only two apart, like 11 & 13, 17 & 19, 41 & 43, etc. So, days like 11/13, where both the month and day are twin primes are called twin prime days.
2. Mileage Magic Ralph drives 60 miles at an average speed of 30 mph (fog maybe?), then returns over the same route at an average speed of 60 mph. What is his average speed for the entire trip?
3. Be careful: What are the next two letters in this sequence?
O, T, T, F, F, S, S, ___, ___
(Lots of ‘right’ answers here. There’s one that fits ‘best'(?), but I’ll take anything you can justify convincingly.)
4. Painted Cube A wooden cube is dropped into red paint. It is then cut into 27 equal-size smaller cubes (3 equal cuts each direction – like a Rubik’s Cube). How many of the smaller cubes are found to have red paint on a) 3 faces, b) 2 faces, c) 1 face, and d) no faces?
5. Easy Money? Let’s suppose that – flush with the elation of my Royals’ success in ’14 – I make this foolish bet: I’ll take the SUM (add them up) of all the Royals‘ game scores next season, and I’ll give you the PRODUCT (multiply them!) of all the Cardinals’ game scores next season, and I’ll bet my number is higher! Foolish bet? How likely would I be to win? [Note that this ‘answer’ requires words, but please don’t run away 🙂 Just make an argument for your case.]
