Pythagoras Word Problems

Try answering these word problems. You can answer them here at the blog or at your class blog.


  1. Tony has got his kite stuck at the top of a very tall tree. He knows the string on his kite is 20 m long. When he pulls the string tight and holds the very end on the ground it touches 17 m from the bottom of the tree. If the ground is flat, how tall is the tree?
  2. Susan is making a jump to ride her bike over. She uses a 1m plank of wood to make the jump, and raises the end 50 cm off the ground with a second piece of wood. How far along the ground from the end of the plank that touches the ground is the second piece of wood?
  3. Robert is using a 5m ladder to climb in his upstairs bedroom window. He finds that if he puts the base of the ladder 3.3m from the wall the top leans on the windowsill. How high from the ground is the windowsill?
  4. The guy wires holding up an 11m radio transmitter join 2m from the top of the aerial, and are anchored to the ground 7m from the base of the aerial. How long are the guy wires?
  5. Tim is standing across a river from Mary. They discover that if they stand exactly opposite each other they can each hold one end of a 5m rope. How long would the rope have to be to reach if Tim moved 8m downstream?

Some Pythagoras work

May 26th Part 1 is due. (This will provide you with great material to study from for your exam)
June 14th Part 2 is due.(You will have access to the Math lab during the week of June 11th to 14th)

This unproject is part of the Term 4. It will be worth 10% of that terms mark.

Instructions

Your job is to be an expert in 2 topics that we have learned this year. You will need to check your math portfolio to check the topics that we have covered.

  1. Data Managemant and Graphs

  2. Probability

  3. Square Roots

  4. Percent

  5. Ratio

  6. Proportional Reasoning

  7. Fractions (only if you did not participate in the first Unproject)

  8. Algebra

  9. Geometry

You will be responsible to create a background page that explains both of your topics. It must be dynamic and hook the audience. You may create the background information at

  • your class blogsite (just create the necessary link)

  • here at the Final Unproject

  • wikispaces (Just create the necessary link)

Your background page must include

  • all needed math information

  • pictures, graphics and other visual aides

  • links to other sites to give more information

  • One or more word problems that are solved correctly.

Your Final Unproject is your last math assignment of Grade 8. It is a celebration of what you have learned. Just like the first unproject you choose what it will be. It can be anything but you must check with me first.


Previous unprojects were


The timing of this project is to help you study for your final exam. If you choose to you can use this project as a way to study for exams.

You may work with a partner but you are both responsible for the final project. Once you have chosen a partner there is no changeing. There will be no groups of 3. Sorry.
