Use King Henry to convert measurements


King HenryGood old King Henry (seen here working on his times tables!). Well, maybe or maybe not. He was, after all, not liked by everyone, so what is he doing on a H3 Maths? Well, “King Henry” is most useful when it comes to doing conversions of measurements. Remember this phrase and you will be able to do conversions of length, areas and volumes really quickly!

King Henry Doesn’t Usually Drink Chocolate Milk” is an acronym – a way to remember the conversion steps:

For example, watch this video to get an idea of how to make the conversions. [H3 Hint: For converted areas simply square the number of steps – for example, Hectares to Sq Metres is two “00” steps = 100×100 or 10,000. So, 1 Hectare = 10,000 sq metres.
For volume, simple cube the number of steps!]

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)?]
