500,000 Hog Hits

Mathspig is sooooooo excited

about reaching:

To celebrate 500,000 or 5×10⁵ hog hits

 and to continue showing mathspiggies everywhere

that maths is fun

and relevant to all

Mathspig presents

The MATHEMATICAL

CABINET OF

500,000

CURIOSITIES!!!

………………………………………

………………………………………………………

If you took a sample of

500,000 US teens

how many DO YOU THINK fall

asleep at school

at least once a week?

You will find amazing US teen stas here:

28% report falling asleep once a week

 500,000 x 28/100

= 140,000

Snoring to the left of you. Snoring to the right of you. You are not alone.

What volume of coke is there in 500,000 cans?

Coke can vol = 355 ml = 12 fl oz

500,000 x 355 = 177,500,000 ml

= 177, 500 l = 177.5 m³

……………………………………………

An average bath uses 150 litres water per bath.

How many bathtubs would 500,000 cans of coke fill?

177,500/150

= 1,183 baths in coke!!!

Hey mathpiggies, wanna bubble bath? You’d be tickled pink.

In a crowd of 500,000 how many people

would have their birthday

on the same day as yours?

There are 365 days in the year so the probability of anyone having their birthday on the same day as you (ignoring leap years) is:

1 in 365 or 1/365.

 

In a crowd of 500,000 the number of people who have a birthday on the same day as you is most likely:

500,000 x 1/365 = 1,370

That’s a lot of birthday cake!!

  How heavy is $500,000 dollars?

 

Australia:

Wt Aus $1 coin = 9.0 g

If the bank gave a bank robber $500,000 in $1 coins it would weigh:

500,000 x 9.0 = 4,500,000 g

= 4,500 kg = 4.5 tonne

………………………………………………

………………………………………………..

UK:

.

Wt UK £1 coin = 9.5 g

500,000 x 9.5 = 4,750,000 g

= 4,750 kg = 4.75 tonne

…………………………………………………..

…………………………………………….

USA:

Wt US $1 coin = 8.1 g

500,000 x 8.1 = 4,050,000 g

= 4,050 kg = 4.05 tonne

You will find all you need to know about the size and weight of US coins and notes here.

$500,000 in $1 notes would only weigh

11 lb or 5 kg.

……………………………………………….

So, um, bank robbers do the maths!!!!!!!!!!!!!!!!!!

………………………………………………

………………………………………………..

How far would you walk in 500,000 steps?

We’ll assume you take a big step of 1m.

So 500,000 m = 500 km.

A comfortable walking rate is 5 km/hr.

How long would it take you to walk 500 km without a break?

500/5 = 100 hrs.

………………………………………………

………………………………………………..

The Bugatti Veyron Super Sport  hits a maximum speed of 267 mph (429 km/h).

How long would it take the Bugatti travelling at top speed – not including refueling time – to clock up 500,000 km?

500,000 /429  = 1165.5 hr

= 48.5 days

The speed of an average sized commercial passenger plane ≈ 500 mph 0r 800 kph or

≈ twice the speed of the Bugatti.

So it would take a passenger plane approx 24 days to travel 500,000 km.

………………………………………………

………………………………………………..

How long would it take you to count to 500,000?

Assuming you count at the rate of 1 per second the time it would take is 500,000 seconds.

500,000/ 60 = 8333 mins = 833/60 hrs

= 13.88 hrs or 13 hrs 53 mins

Come on! You could do that mathspiggies!!!!!

………………………………………………

………………………………………………..

 In a group of 500,000 US teens how many are serious cave dwellers or, to be more accurate, how many spend less than 3 hrs a week outdoors?

It is an amazing 30.1%.

500,000 x 30.1/100

= 150, 500 creatures of the gloom.

Come on you teen gloomagogs get outdoors. You need the sun. You need the Vitamin D.

How many calories in 500,000 m&ms?

There are an amazing 400 million m&ms produced everyday in the US. One m&m weighs 0.7g.

And calories in 1 m&m =  3.4 cal

500,000 m&ms weigh:

500,000 x 0.7 = 350,000 g

= 350 kg

As 400 million or 8 x 500,000 m&ms are produced each day, that is 8 x350 kg or 2800 kg or 2.8 tonne.

Calories in 500,000 m&ms is:

500,000 x 3.4 = 1, 700, 000 Cal

As the average consumptionof chocolate in the US is 5.18 kg per year eating 500,000 m&ms would take:

350 kg/ 5.18 kg

= 67.6 years!!!!!!!!!!!!!!!!!!!!!!!!

You better get going!!!!!

………………………………………………

………………………………………………..

Blink rates vary but the average blink rate in a laboratory setting for a human is 10 blinks per minute.

How long would it take for you to blink 500,000 times?

500,000/10 = 50,000 minutes

= 50,000/60 hrs = 833.3 hrs

= 833.3/24 = 34.7 days

= 34 days 17 hrs 17 mins

But don’t think it or you’ll go blink crazy!!!!

Easter Egg Maths for Chocoholics!

Mathspig is, interested in the yummy-yummy weight of chocolate Easter Eggs and Rabbits. We even have Easter Bilbies in Australia.

 They’re so cute.

Once when Mathpigs little mathspiggies were in kinder we raffled a 5 kg Chocolate Rabbit called Rolf. People bought tickets but nobody actually wanted to win a 5 kg  ( 11 lb) chocolate killer rabbit called Rolf. Twice the winners donated Rolf back to good causes.  OMG, Rolf might still be doing the fund raising rounds terrifying little kids.

Is this Rolf?

EASTER EGG MATHS

So how heavy is a giant Easter Egg?

We can work it out mathspigs.

We can use the  formula for the volume of an ellipsoid to calculate the weight of a chocolate egg. It is an approximation.

The Density of Chocolate comes from the Mary Williams-Norton Lab Report.

8888

*************************************************************************

Bigger than this one!

 888888888888888888888888888888888888

How Eating Chocolate Helps You Do Algebra:

Does the equation work? We’ll find out mathspigs.

Here is the best part:

Buy a Chocolate Easter Egg:

Measure:  b=  Height/2   cm*

                    a = Diameter /2   cm*

*( Measure Height and Diameter by holding the egg between 2 books)

   Thickness egg wall t =    ….. cm  

Density of Chocolate = 1.325 g/cm³   

***************************************************************************

*

***************************************************************************

***************************Now I will weigh my egg pieces. I had to break it to check the egg wall width I did. Really. **************************

***************************************************************************

According to the Guinness Book of Records The largest chocolate rabbit in the world in fact.  Yes, this fella weighs 2,800 kg (6172 lb 15 oz) and is 3.4 m (11 ft) high and 2.2 m (7 ft) in diameter and was made in Brazil in 2009.  How many years would it take to eat that whopper bunny?

It is heavier than a Ford E-350 Extended Van with 6.8 litre V10 which weighs in @ 2,598.5 kg (5,729 lb)

Ahhhhh!!!!! The killer rabbit is comin’ back to get me. Ahhh!!!!!!!!!!!!!!!!!!

Little Lego Men Need lotsa Lego Maths

…………………………………………………………….

………………………………………………………………………………………

There is a lot of maths in Lego, mathspigs, but rather than smash up bridges not to mention toes with 40 kg weights, here are some other cool ways to do LEGO MATHS.

You can make yourself into a Lego Figure like Mathspig, but first ….

………………

…………………….

………..

………………

Ideally, students would measure their own Lego Man. Otherwise, use the dimensions shown and fill in the chart. 

To calculate your Lego man conversion factor:

   Lego Conversion Factor =   Your Height mm/ Lego Man height mm

eg. Mathspig Height = 172 cm

Mathspig Lego Conversion = 1720/ 38.2 =  44.6

A full size Lego Mathspig is 172 cm, therefore a full sized lego Mathspigs legs would be:

Mathspig Lego Legs = 14.0 x 44.6 = 624.4 mm = 62.4 cm

Dimensions mm	Lego Man Dimensions mm	Your Real Dimensions mm	Your Lego Man Dimension mm
Height (Not including the round thing ie. the stub)	38.6
Head Height Top to chin	8.5	************
Neck	1.2	*************
Torso Shoulder to hip (Swivel pt)	14.9	************
Leg Length Hip to Floor	14.0	************

Now you could draw or photo shop a real picture of yourself to these dimensions or – this is so cool – just make a Lego Man Pic of yourself @ Reasonably Clever

Zombie maths 6: Decimals

According to the online news blog, 24/7 Wall St, Zombies are now big business.

They estimated that Zombies earned the USA $5.74 Billion in the last 10 years. It’s not just films such as Resident Evil, Dawn of the Dead and Zombieland that bring in the big bucks. The undead also bring in the dollars through video games such as House of the Dead, Call of Duty: World at War and Plants vs Zombies.

Here are some estimates:

Movies………….$2.5 billion

Games………….$2.5 billion

Comics, mags….$50 million

books ……………$100 million

Halloween……$0.55 billion*

Conventions……$10 million

Merchandise….$10 million

……………………………….….Music……………..$ 10 million

……………………………….….Art ………………… $10million

…………………………………………………*Mathspig used low estimate here.

ZOMBIE MAKE $$#$$$$^$#$$$@$$&$$$

+++++++ = $$$$$$$$$++++++++++$$$$$$$$

IT ALL ADDS UP!
