I've seen this one worked and all I'll say is "I'll buy that for a buck." Hint--it's a reverse substitution to a common code.

I build up castles.
I tear down mountains.
I make some men blind,
I help others to see.

Three lives have I.
Gentle enough to soothe the skin,
Light enough to caress the sky,
Hard enough to crack rocks.

I only had one course in linear algebra, and it didn't excite me.

You'll have to try harder to get me to stay away. However, I don't submit answers if the correct ones have already been sumitted unless I have something new to add. Rap's got a few time zones on me.

These were crip. What were the answers to the vector problems?

we both blew 10000 markr

10000=100^2=10^4=2^4*5^4

2^4=16

5^4=625

16*625=10000

now both our foreheads are sloped together.

Late breaking news:

"10000=100^2=10^4=2^4*5^4

2^4=16
&
5^4=625

16*625=10000 "

True, so very true.





A certain natural number is divisible by 3 and also by 5. When the number is divided by 7, the remainder is 4. What is the smallest number that satisfies these conditions


A4273B is a six-digit number in which A and B are digits, and the number is divisible by 72 without remainder. What is the value of A and the value of B


Of three numbers, two are 1/2 and 1/3. What should the third number be so that the average of all three is 1

Of no use to one.
Yet absolute bliss to two.
The small boy gets it for nothing.
The young man has to lie for it.
The old man has to buy it.
The baby's right,
The lover's privilege,
The hypocrite's mask.
To the young girl, faith;
To the married woman, hope;
To the old maid, charity.

The following anecdote is told of the great German mathematician Carl Friedrich Gauss: His teacher had to leave the class urgently for a few minutes. He therefore presented an arithmetic problem to his pupils, so that they would be busy for a while: They were to add all numbers from 1 to 100. The teacher was just about to leave the classroom, when the young Gauss presented him the solution in his exercise book: 5050. The teacher was astonished. Since he had already let another class do the job count, he knew that the result was correct.

How had Carl calculated it so fast

Seeing how good you are (not) with 1000. :wink:

What is the Total of the numbers from 1 to 1000




Quick, you don't have much time-

A road roller drives along a road 6 m wide and covers a quarter of a meter in 24 seconds. a snail 50 meters ahead begins to cross the road with a speed of 8 cm per minute. Question: Will the road roller crush the snail



You can't foil me!

Aluminum foil is producible in a thickness of 0.06 mm (= 60 micrometers). The usual kitchen aluminum foil has a width of 29,7 cm (= the long side of the DIN A4 format! Why that ).

How many meters of kitchen foil could be obtained from 1 kg of aluminum (density of aluminum: 2.7 grams per cubic centimeter)

How much does a kitchen foil role of 30 m weigh (without the inner cardboard role!)


Good luck or good buy.

jung Herr Gauss:

5050 = (100*101)/2

in general, sum of integers from 1 to n is n*(n+1)/2

1) 3|n & 5|n and nmod7=4

n=15x 15xmod7=4 equivalent to 1xmod7=4
so x=4 for min &
n=60

2) A273B=52736 and (A,B)=(5,6)
52736/72=7538

3) x3=2 1/6

4) n(n+1)(n+2)=15600
m^3+3n^2+2n-15600=o
using cubic root solver twh are imaginary and the other is 24
so n=25
&
24*25*26=15600

5) 5 1/3-3 1/3 + 5 1/2-2 1/2=2+3=5

6) If I remember right there are five points in a tennis game Sumpin, Deuce, Add, Love, Game

7) Rear Wheels

8) Boobs

Rap

I missed the one from Lash...

An easier approach to the consecutive numbers

(3na+2)/3 is about equal to (15600)^(1/3)=24.986

This isn't a whole number, but na=24 can be quickly identified as a possibility as the starting number as (24+25+26)/3=25 and 24*25*26=15600.

Repentance calcs

Gauss' trick Sum(i) for i=1 to 100 is the sum of 1+99 & 2+98 &.....& 49+51 & 50, or 50*100+50=5000+50=5050

Sum(i) for i=1 to 1000=500*1000+500=500500.

The snail lives. It takes 75 minutes for the snail to cross the road and 80 minutes for the roller to get to the snail.

Aluminum foil

1 kg makes 20.78 hm of foil. 30hm of foil weighs 1.45 kg.

Rap

FOIL
I get 20.78m and 1.44kg

I wouldn't have guessed that a roll weighs over 3 pounds.

15600
I factored 15600. 13 is a factor, but is too small. 26 worked out. Cube root is the way to go.

Interesting approach markr

15600=2^4*3*5^2*13

5^2=25
2*13=26
2^2*3=24

I can see this as a simple solution.
