Maths we have done throughout the year.

Have you ever thought how big space was, well I have, If you haven't you are in the right place take a seat,  first I am going to take you through our learning in 9-ay an I am going to be showing you what we have been learning in 9-ay. The first thing we learn't was how much water was in the world and we had to do all the calculations to find out the answers which was.

Roughly 1.260,000,000,000,000,000,000 litres. 10^18

The next topic we done was small things are and we found out that bed bugs are really small same as sand flies here is our working out.

How small are bed bugs

bed bugs range from the size of a bed bug egg (0.09 inches, 2.5 mm) to the size of full adult bed bugs at ( 0.18 inches, 4.5 mm). For reference, 0.1 inches is slightly over the thickness of a quarter. Adult bed bugs are the size of an apple seed which is pretty small.

How small is a sand fly

Only about 3 mm long

After that we went on to how log would it take to fly around the universe in a Airbus A380 we had to do a lot of calculations to eventually find out the answer this is the first thing we worked on , Scroll across.

The second thing we worked on was how long It Is to Neptune.

Neptune Logan and Josh

Distance to Neptune

4.3 x 10^9

hrs

105120

days

4380

years

my airbus speed

925

km

0.00464864864

time to get to Neptune is

4.3 10^9

divided by 925

0.00464864864

Hrs to get to Neptune

105120

so it takes

12 years

4380 days

105120 hours

to get to Neptune

Eventually after that work we moved onto If the golfer it the ball such and such away.

1st Hit	2nd Hit	3rd Hit	4th Hit
175 m	130 m	40 m	5 m

You take the 5 from the 4th hit and add it to the first hit so that makes 180 m and then you add the 100 from the second hit which then makes 280 m and then take the 310 m then you add the 40 from the 3rd hit which makes 350.

1st He hit 50% of the goal - because half of 350  is 175 and since he hit 175 that means he hit 50% of the goal.

2nd Hit 34%

3rd Hit 14.5%

4th Hit 1.5 %
