4.1+Using+Similarity+to+Solve+a+Mystery

//**Problem 4.1 The teachers guides for Connected Mathematics measure 8 1/2 x 11". Below is a photograph of a middle school teacher holding a teachers guide. A. Use the photograph to figure out how tall the teacher is. Explain your procedure.**// I found how tall she was by measuring the book lelegth ( In the picture) with her hight in the picture of the teacher. The book is 11 inchis and I found 7 of tose in the teacher. The I mulitplied 11x7= 77in. The I divided 77/12= 6.4 feet.

//**B. How do you think the police determined the robber's height?**// If he was standing in front of the cash register they could measure the hight of the cash register and then with the cash register they do the same thing I did above with the books.

//**Problem 4.1 Follow-up 1. Estimate the height of the door in the photograph.**// //The door is taller then the teacher so maybe about 7 feet.// //**2. Do you think your estimate in question 1 is an underestimate or an overestimate. Why?**// I think my estimate is close because most are 7 feet or around there but some doors are bigger so they would make my estimate under.
