A l'ttle maths quiz :) Easy peasy. Just for fun!

[aommaster]

1. Taking an exact number of strides I can walk 9.49 metres. What is the length of my stride?

 

2. Make a copy of a triangle like that shown with four circles along each edge. Use the numbers 1 to 9. Put one number in each circle so that the four numbers along each edge add up to the same total. Find two different ways of doing this.

3.If you multiply together all of the factors of 100, how many zeros will there be on the end of the answer?

 

4.In this multiplication problem: ?? x ? = ??? all of the digits have been replaced by a ?. The missing digits are 1, 2, 3, 4, 5, 6. If each digit is used once only find the correct version of the problem.

 

5.When my age is divided by 2, 3, 4 or 6 there is always a remainder of 1, but when divided by 7 there is no remainder. What age am I?

 

6. How many squares are there in the diagram below?

7.In what year (in the 20th century) would a person have been able to say “My age this year is the square root of the year in which I was born”.

 

 

 

Have fun!!!

WHOA! man, that was good!

I'll have to check it. i'll give you feedback. It looks all correct

[wolfson]

oopps

 

6. 27

 

and

 

7.1936(44^2)

[aommaster]

ok. No problem. Man, i just wish i were like u

[aommaster]

umm... by the way. How did u work out the squares question. Question 7

[YT2095]

What a dude!!!

 

YT2095 passes Wolfson a Beer, you`ve earned it man!

[aommaster]

yeah, but, the square thing looks a little weird, ITS TOO HIGH to me

[Kedas]

7 Is rather simple:

 

20th century 1900 - 1999

sqrt(1999) = 44.710...

sqrt(1900) = 43.588...

 

Know any other whole numbers than 44 between those?

 

44*44 = 1936

 

about 1) why is 9.49/10= 0.949 less correct ??

 

correction add 44+1936=1980

(not the year he was born but the year in which he said this)

[wolfson]

1. I think they wanted a value excluding first value integers.

 

thank you for the correction i did mean to add them.

 

The count the square questions, well i added the dependent (structural) and independent (non-structural) squares, i.e. 3by3, 2by2, 1by1 ect....., i got 27 which i think is a mean approx.

 

OHHH YES Ty v much YT and aommaster, look forward to some more!!!!

[aommaster]

ok. Wolfson, want some more? There is one up right now on my site. If you DO want to take aprt, it would be a great honour

You have to first register in my forums and then post the answer.

By the way, take a look at my science section
