Paper airplane designed by engineers breaks world distance record

April15

(just in from cnn): The world record for the farthest flight by paper airplane has been broken by three aerospace engineers with a paper aircraft that flew a grand total of 289 feet, 9 inches (88 meters), nearly the length of an American football field. The feat required months of effort, as the team put […]

A Celestial Tug of War

March5

Throughout human history the Moon has been an inextricable, ghostly presence above the Earth. Its gentle gravitational tug sets the rhythm of the tides, while its pale light illuminates the nocturnal nuptials of many species. Entire civilisations have set their calendars by it as it has waxed and waned, and some animals – such as […]

The Missing 49 Kms in New Zealand

October9

[article from Stuff] – Somewhere, somehow, 49 kilometres have gone missing in New Zealand. Government agencies don’t know where they are. Neither do a range of local boards, experts and transport policy wonks. But what we do know is this: at opposite ends of the country, in Bluff (in the south) and Cape Rēinga (in the […]

How long to Drive to the Sun?

October7

How long would it take to drive to the sun? Longer than you think. The distance from the Sun to the Earth is around 93 million miles. Theoretically, If a person drove a car (with an unlimited amount of fuel) at a speed of 93 miles an hour (about 150 km/hr), then it would take […]

Prize Object Puzzle: If Sue does not know where the prize is in the first question, it can’t be under the square. She must have been told it is under another shape. Apply this same logic to Colin. It is then obvious that the prize cannot be under a yellow object. That helps Sue eliminate her yellow shapes. Got the idea?

Algebra Puzzle: Answer = 1

Popular Math Problems Answers: 1, 1

Number of tabs? According to Lifehacker, the ideal number of tabs you should have open is nine. Yes, a single digit. To some, this is like playing a piano and only using a fraction of the notes!

Worst Graph? Where to start. What a visual mess and even some of the lines merge and are impossible to follow. A graph is a visual display of data, with the goal to identify trends or patterns. This is a spider’s web of information which fails to show a clear pattern at all. Solution? Well, different colors would help, or why not group in two or three graphs where trends are similar?

Homework Puzzle; The total value of the counters is 486, so halve this to get 243. Now, arrange the counters to equal this amount twice.

The graph on the left (Coronavirus) is for a time period of 30 days, while the one on the right (SARS) is for 8 months! Very poor graphical comparison and hardly relevant, unless it is attempting to downplay the seriousness of the coronavirus?

10 x 9 x 8 + (7 + 6) x 5 x 4 x (3 + 2) x 1 = 2020

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
