I bet /a/ can't solve this.

>>152420181
2nd hint isn't useless. It discards any possible odd answer, like 15 (15 divided by 7 has a remainder of 1, but since it's odd, it has a remainder of 1 when divided by 2).

This means any even number which fits the 1st hint can be the right answer, like 22. It's still a very easy and dumb math problem, though.

>>152420627
I think you should read the second hint more carefully, anon.

>>152421082
>>152421084

>>152420971
Actually, I misread the 1st hint. It needs to have a remainder of 1 when divided by 3, 5 and 7 at the same time to satisfy the equation, not only one of the three. In that case, 36 is an acceptable answer.

>>152421483
It is? It says "an" odd number, not all.

I did misread it, I included 9 here >>152421450
10, 19, and 28 are gone.

>>152421483
But dividing 36 by 3 wouldn't give a remainder of 1

>>152421477

actually it's 7:31

>>152421477
Each square section in >>152421084
contains two halves one with all blue and one with two red triangles.

Blue = s*h
mixed = two triangles of height (h/2) and side s
so = 2 * (s)*(h/4) = 0.5 *s*h
making the other 0.5*s*h blue

each rectangle is 25% red 75% blue.

1 seems right

1 divided by 3 through 9 has a remainder of 1
1 divided by 2 through 8 has a remainder of 1

>>152421557
>>152421583
Yeah, I was retarded. The right answer is 106 (because it's 3 times 5 times 7 plus 1), or 105 times anything plus 1.
And yeah, the 2nd hint was useless, since that will always be even anyway. I didn't think things through. Sorry.

X % 3 = 1
X % 5 = 1
X % 7 = 1

X % 2 != 1
X % 4 != 1
X % 6 != 1
X % 8 != 1

Therefore X = 106

106 % 3 = 1
106 % 5 = 1
106 % 7 = 1

106 % 2 = 0 (not = 1)
106 % 4 = 2 (not = 1)
106 % 6 = 4 (not = 1)
106 % 8 = 2 (not = 1)

Is the circle in the top right meant to touch the right edge of the square?

>>152420025
N % 2 != 1, so the number is required to be even.
N - 1 = a * 3 = b * 5 = c * 7

N - 1 is odd, and the numbers on the right are odd, so logically a, b and c must all be odd.

Additionally, all these numbers are primes, so no common divisors exist. This means that the first possible number is 3 * 5 * 7 + 1 = 106.

Next valid combinations are d * 3 * 5 * 7 + 1 for any odd d:

As the set of odd numbers is infinite, this means there are infinite possible answers to your question. Please come with an actual solvable riddle next time.

The tessellating element is a rhombic tile consisting of a blue central hexagon and two red diametrically opposite triangles contiguous thereto, which has a red to blue area ratio of 1:4. Presumably your mistake was in thinking that the Star of David figure is the generating tile, which would be in error since the tiles shouldn't overlap.

>>152428193
Nope.

>>152429539
It says that the pattern continues along a plane, means it will go infinitely.
When it goes infinitely, then the ratio of red against blue will be 1:1

>>152429630
>there are people this stupid on /a/

All these brilliant minds and still jobless.
Math is useless Logic is useless Science is useless

>>152429539
I meant to say 1:4 is the ratio of red to the total plane area.
>>152429630
I am assuming a very standard assumption where the ratio at infinity is implicitly taken to mean the limiting behaviour of the ratio (red area in consideration):(total area in consideration) as the total area under consideration tends to infinity.

>>152444357
To the right. Buoyancy applies to the metal ball thus transferring it's weight to the water.

>>152444357
Tips to the left as the ping pong ball is linked to the left side of the scale and thus contributes to its mass. The steel ball is suspended from outside the system and as such doesn't affect the right side's mass in any way.

>>152444518
Buoyancy would only add mass to the right side if the object is of less density than the liquid it's are submersed in, steel is far denser than water, so its presence doesn't affect the scales.

Oh. Fuck.

I don't think this has a solution.

>>152444357
Buoyancy means the steel ball still applies a strength to the water equal to the weight of its volume of water. On the left side, for the same volume, we have a ping-pong ball lighter than water, so less force is applied to the scale, which would then tip right. The string's weight isn't significant, or it would keep the ping-pong ball down by weight alone without tying it down (if it IS that heavy, the scale would tip left).

Sure it does.
