Do we want another endangered species? Well badger culling will do just that. The UK has decided to stop Badger culling to prevent their extinction. I believe this is the right course of action if we want them to stay around.


Here are my three reasons to stop badger culling:

1. If we keep doing this, Badgers will become extinct.
2. There is no real reason why we should have started in the first place.
3. Killing badgers won't really stop anything except for their population growth.

A, B, C, D = Tank sides

E = Bottom

A + B + C + D = 90cm x 150cm x 4 = 54000cm2

E = 90cm x 90cm = 8100cm2

Total = A + B +C + D + E = 54000 + 8100 = 62100cm2 = 621m2

Glass cost = Total x 24 = 621 x 24 = $14904

It will cost them $14904 to build their aquarium.

Even though I as a person don’t really drink chocolate milk, I support chocolate milk in schools. Without chocolate milk, what else would kids drink? Probably just pop if the school had it, or artificially flavoured juices which is even worse, plus, they would probably take more cans of soda than small cartons or bottles of chocolate milk. At least chocolate milk has some dairy ingredients in it. Meanwhile soda probably has no nutrition at all! The chocolate milk can also have reduced fat or low calories or both! Which would you rather have kids drinking? You decide.

I think 3 reasons to have chocolate milk is because:

1.   If there was no chocolate milk kids would rather have soda which is unhealthy.

2.   Chocolate milk has dairy in it which has some nutrition in it. You would probably get more out of this than soda or just plain water.

3.   Some Chocolate milk has reduced fat or low calories or both which makes it more healthy than the regular kind, but still you shouldn’t have it every day.

1)

   Geoff’s Parallelogram

Area = 144cm2

Height = 10cm

Base = ?

Height X Base = Area

Area ÷ Height = Base

144 ÷ 10 = 14.4

Base = 14.4cm

    Lynn’s Triangle

Area = 144cm2

Base = 12cm

Height = ?

Height X Base ÷ 2 = Area

144 ÷ 12 X 2 = 12 X 2 = 24

Height = 24 cm

     Brian’s parallelogram

Height = 20cm

Base = 15cm

Area = ?

Height X Base = Area

20 X 15 = 300

Area = 300cm2

      Brian’s triangle

Height = 20cm

Base = half of parallelogram’s base = 7.5

Area = ?

Height X Base ÷ 2 = Area

20 X 7.5 ÷ 2 = 150 ÷ 2 = 75

Area = 75

Area not covered by triangle = 300cm2 – 75cm2 = 225cm2

225cm2 of the parallelogram is not covered by the triangle.

2)

    On any triangle (except for the isosceles triangle because there are two equal sides,) the base line is the longest line (but because the isosceles triangle has 2 equal sides, the base line is the line not equal to the other sides). The height line is 90 degrees from the base line and is usually inside the shape but you don’t see the actual line, unless it is a right angle triangle. The 90 degree angle is important because The height just can’t be any random line on the triangle that’s facing up or the second longest. It has to be 90 degrees from the base line because the height line is facing the top and bottom. The base is the bottom.
