QUIZ CORNER 1. (\_/)_(\_/)_(\_/)_(\_/)_(\_/)_


1. REACH OUR SET: What eleven letter can be found by rearranging the letters in this anagram?

2. We are considering the age of 3 brothers, given as whole numbers. Mark is 4 times as old as Philip.  Brad
is 7 times as old as Philip.  So to find Mark's age,  multiply Philip's age by 4.  If you turn the calculator    around so that you are looking at the number upside down, you get Brad's age. How old are the 3 brothers?

3. At the end of a pier is a flat rock 2 meters below the surface. The government can measure the water level in the lake by sticking a long stick with centimeter markings into the water until it reaches the rock and then reading off  the number. The ice is 50 cm thick. They drill a hole in the ice 15 cm in diameter and measure the water level in   the hole.  Ice has a density 0.9 times the density of water, so the surface of the ice is 5 cm higher than the level of water in the hole.  If the ice were to  suddenly melt, how
   would the level of the water change?
