Math

Tomorrow there is a final assessment of adding and subtracting integers.  In class today we did a small review quiz so students could gauge their own understanding.  Anyone who struggled through that should be doing online practice at home such as this.  All students have a word problems assignment due tomorrow.  There was a printing error with the assignments so the last 4 questions did not appear so I have posted them below.

5. The base of a volcano is 3000 m below the surface of the ocean. The total height of the volcano is 5000 m. What is the altitude of the volcano above sea level?

6.  On Monday morning Sam had $50 in his wallet.  The following table shows how this amount changes over the week.  How much did Sam put into, or take out of, his wallet on Friday afternoon?

7.  Lloyd is lifting weights over a nine-week training period.  Every week he lifts 2kg more than he lifts the previous week.  During the ninth week, he lifts 80 kg.  How much was he lifting during his first week?

8.  Evan hiked uphill from a valley that was 45 m below sea level.  After an hour he was 100m higher than where he started.  Using integers, determine how high he was above sea level.  Show what you did.
