Unit 2 Summary
What do I need to know from Chapters 9 & 10?
Measuring Length & the Metric System
3 ft = 1 yd
5280 ft = 1 mile
*Metric System: 1 km = 1000 m
1 hm = 100 m
1 dam = 10 m
1 dm = 0.1 m
1 cm = 0.01 m
1 mm = 0.001 m
* Dimensional Analysis - changing units within the English system, within the Metric system, and change units from English to Metric and vice versa

Weight & Temperature
See https://www.youtube.com/watch?v=NqbkvEK46xM for examples
* Weight
English system: 16 oz = 1 lb 2000 lbs = 1 T
Metric system: 1 kg = 1000 g 1 hg = 100 g 1 mg = 0.001 g
(see picture below)
* Convert from weights from English system to Metric system
See https://www.youtube.com/watch?v=LGI34L4pw_w for examples
*Review your 9.3 homework and see http://sites.gpc.edu/tlamar2/chapter-9-math-1001/
ON PAGES 607-608 IN YOUR E-TEXTBOOK, TAKE THE CHAPTER 9 TEST. EACH QUESTION HAS A VIDEO CAMERA ICON ON THE LEFT WHERE YOU CAN SEE THE PROBLEM WORKED OUT AFTER YOU TRY IT.
Triangles
