The rules for Seesaw Ring Toss are simple: a team of two players throws rings at the target shown in the ﬁgure below. Once all the rings have been thrown, the end supports are removed and seesaw is allowed to pivot. If the seesaw does not stay horizontal, the team fails is awarded zeropoigits for that round. Below are pictures of targets aﬁer the rings have been eggs-H
thrown but before the supports have been removed; can you» predict which teams will be get points and which will receive scores of zero before the supports are even removed? Invent a way to decide whether a given target will pass or fail just by looking at it. Circle the targets that
you think will pass. Team ‘c e co BONGO Team 9
3 g, The rocket boost index Rocket companies are competing to have their model selected for the next launch! As head propulsion
engineer, you know you will need a lot of engine power for this project. The problem is even tougher
because some rockets have multiple stages. The applicants and their engine stats are below; how can
you quantify which engine will give your payload the biggest boost to get it into a proper orbit?
