Ruby is in the 10th grade and loves math and realizes that math is everywhere! She wants to show you her day to day life and how math relates to everything she does.
After school one day Ruby and her friends went out for pizza. The pizza cost $20. There were four fewer people contributing to the pizza than the original plan. Each person had to now give 25 cents more. Ruby is now wondering how many people were supposed to come originally?
To get home Ruby has to use the ferry to cross the body of water.
The ferry is due to cruise south. After 1 hour Ruby realizes that the ferry is actually S50°W. Ruby wonders if he was travelling at a speed of 100km/h how far off course are they?
After Ruby finally arrives home she realizes her mom is trying to figure something out so she goes to ask if she need help
Hey Mom! What're you doing?
Hey Ruby! I was just trying to figure out what dimensions would create the largest fencing around this pool. But one side doesn't need fencing because of the shed
Hmmm since one side of the pool is against the shed and we only have 400m of fencing I wonder what dimensions would maximize the area
