It All Adds Up

Thames High School’s ‘mathletes’ have been busy calculating during 2015’s Maths Week.

Three THS teams headed over to Hamilton to compete against 21 other regional schools in the annual WaiMaths competition.

The year 9 team included Eva Sorenson, Ester Schuchardt and Max Nankivell. The year 10 team was made up of Claudia Long, Sophie Clarke and James Harris. And the Year 11s were represented by Danielle Goodall and Jess Juby.  Maths teacher Linnea McDonald said “It was an exciting night and the students did us proud!”

Meanwhile, back at school 10MCD and A3 JAG won the week long maths quiz. In second place were 9 SIM and H3 HUR, and third place went to 9EMY and D1 JHA.

The students were awarded house points for their entries. After the big count, Dorrington had 132 points, Rudman had 194, Holt 222 and Adams a massive 342 points.

What fraction of the tank (initially empty) will be filled in 1.29 hours if all three pipes are in operation? Give your answer to two decimal places (e.g. 0.25, 0.50, or 0.75).
