Im Sure This Will Cause A Few Arguments

Hope you like these questions.

Question 0

What is the largest product of a 5 digit and 4 digit number you can make using the digits 1 to 5 only once?

Question 1

I am a two digit number.

I am 5 times the sum of my digits

What number am I.

Question 2

An internet cable runs around the equator of the earth. How much cable would you need (to the nearest metre) If you wanted to put it on 10m pylons rather then just lying on the ground?

Question 0

55555 x 5555 = 308608025

Question 2

Length needed = 2 * 3.1415 * (10M + distance from surface of earth to center of hell measured in meters)

Circumference = 2piR

Question 0

What is the largest product of a 5 digit and 4 digit number you can make using the digits 1 to 5 only once?

Hmmm... so I can use the digits 1 to 5 only once. That doesn't prohibit me from using other digits :D Your question does implicate I have to use them once and only once though.
So I'd say it's something like 99543 x 9921 = 987566103 (product of a 5 digit and 4 digit numer with the digits 1 to 5 used only once)...

Question 1

I am a two digit number.

I am 5 times the sum of my digits.

What number am I.

00 ? Sum is 0, 5 times zero still is 0... Does that count? :D

Question 1

5(a + b) = 10a + b
5a + 5b = 10a + b
-5a + 4b = 0

a = 4, b = 5

-5 * 4 + 4 * 5 = 0

The number is 45. :)

ALL THESE ANSWERS ARE WRONG I SAID 1 TO NINE ONLY ONCE IE 123 + 456 ETC

Omen---how far apart are the pylons--or is there only one each on opposing sides of the equator? If there are only 2 pylons opposed--and using 25000 mile circumferance(changed into meters) them my guess would be 40233631.53 meters---- Doc51

OOPS ! I fogot to enter the difference---31.39 meters. Doc51
