Sorry kiddos, I will have to post the HW to Lesson 9 on Thursday; left the book at school. One day soon, I hope to be able to post to this site at school.
Today in class students worked to use different scales to draw the same triangle shape. We divided up the original meter lengths into scaled centimeter pieces, and then saw how multiplying the scale as a fraction with the original lengths gets the same answer. Answers to HW: 1a. Because the scale drawing is 10 cm long and 5 cm wide, the actual pool is 10 m long and 5 m wide. b. It will be smaller because it will take fewer cm to represent the actual width and length of the pool. c. Your pool should be about 1/2 the size of the given scale drawing; 5 cm long, and 2.5 cm wide. 2. The larger map has the scale of 1 inch to 500 feet. It takes twice the number of units on this map to represent the same distance as the other scaled map. Think about 1 inch = 1000 feet vs. 1 inch = only 500 feet, so 2 inches represents 1000 feet here. 3. Han is not correct. Every square inch represents a 12x12 square or 144 square feet in the restaurant. Actual area = 8,640 square feet. 4. 186 5. angle DEF angle EFD segment DF segment ED
