>>713524259
Too goddamn many. Nobody needs that many bowling balls. Goddamn western civilization.
A lot

At least 6.

>>713524259
More than 1

how the fuck did you manage to get 143

dont care just wanna remove one of the side planks. for the lulz

did you just make up random numbers and add them together? the correct answer would ultimatively be

What the fuck did you just fucking say about me, you little bitch? I’ll have you know I graduated top of my class in the Navy Seals, and I’ve been involved in numerous secret raids on Al-Quaeda, and I have over 300 confirmed kills. I am trained in gorilla warfare and I’m the top sniper in the entire US armed forces. You are nothing to me but just another target. I will wipe you the fuck out with precision the likes of which has never been seen before on this Earth, mark my fucking words. You think you can get away with saying that shit to me over the Internet? Think again, fucker. As we speak I am contacting my secret network of spies across the USA and your IP is being traced right now so you better prepare for the storm, maggot. The storm that wipes out the pathetic little thing you call your life. You’re fucking dead, kid. I can be anywhere, anytime, and I can kill you in over seven hundred ways, and that’s just with my bare hands. Not only am I extensively trained in unarmed combat, but I have access to the entire arsenal of the United States Marine Corps and I will use it to its full extent to wipe your miserable ass off the face of the continent, you little shit. If only you could have known what unholy retribution your little “clever” comment was about to bring down upon you, maybe you would have held your fucking tongue. But you couldn’t, you didn’t, and now you’re paying the price, you goddamn idiot. I will shit fury all over you and you will drown in it. You’re fucking dead, kiddo.
Easy. Pick a side, count each triangle downwards, then add them up.
1 + 3 + 6 + 10 + 15 + 21 + 28 + 36 + 45 = 165.
>>713525444
Didnt read KYS
>>713525002
wtf is this
>>713525361
I'm not wrong. Well yes, the answer is actually 81, as you can only really see 81 bowlingballs.
>>713525204
so?

The base is triangular, not square. That's where he and I fucked up.
143 if it has 4 sides
%triforce
>>713525612
he didn't ask how many you see, he asked how many are there. You have to count the balls that are inside.
>>713525838
good now remove 1/4 and tadaa
>>713525880
Could be just a shell of balls glued together.

>>713525880
there could be anything inside, youre making an assumption you degenerate
>>713524259
There are surely many millions of bowling balls... people bowl all over the world.
>>713525810
Base is square. optical illusion
>>713525880
I wrote 165 further up, the thing is - the question is poorly written. "How many bowling balls are there" could be short for "how many are in the picture", which would be 81, as that's all we can see.
If he asked how many were in the stack, the correct answer would be 165.
>>713525648

>>713526113
I think y6ou are being fooled by the little flat bit on the corner. Look at how they are stacked -- it's a tetrahedron.
>>713524259
i don't know

this, the base corner meets at less than 90 degrees
I guess it could still be some irregular shape

There's no room for that forth corner in the back. It has to be like a pool triangle.

dont fall for the bait
Base is triangular, check the perspective lines, even if poorly done. To the left they meet more or less at the same point, as they should. To the right the house's and fence's meet roughly at same point. So should the 'pyramid line' too, had it been a square (laws of perspective). It doesn't, it has a completely different direction, so not square, but triangular. End of story.
Tl:dr. proof pyramide is triangular.

so 143 balls?

Surprise CockFag! It's 4 sided, not a triangle. The camera lens distorts the perspective.
>>713527423
>so 143 balls?
I don't know, I'm not good at maths, I just made some perspective lines.
THE ANSWER IS 165. 9 rows down. Each row is a triangle.
>inb4 triangular number is a thing
https://en.wikipedia.org/wiki/Triangular_number
addup the first 9 triangular numbers besides 0
you get 165
it's the answer
at least -3
>>713527029
Right idea but wrong thinking of what factorial is (!)
That's multiplication of all lower digits, not addition.
So 9! = 9*8*7*6*5*4*3*2*1 not 9+8+7+6+5+4+3+2+1
The solution is the 9th tetrahedral number. The tetrahedral numbers are given by T_n=(1/6)n^3+(1/2)n^2+(1/3)n. With n=9, that gives T_9=165.

these faggots are right
/thread
>>713527423
At any given level there is a triangle but it doesn't work with that formula since it's made of discrete objects. At any given triangle, the base is of size n, then the next level up is n-1, etc. so at any given level with side length n, the amount of balls at that level is n*(n-1)/2, not simply n*n/2. So it basically turns into
sum[i=1 -> 9]{ i * (i-1) / 2 }
solve that and you're good. I'm too lazy.
>>713527958
>I compete math nationally
shure you do Anon. shure you do
>>713525002
I failed maths in high school, but this has me laffin
definitely 165
>>713524259
We can only see the outer layer of bowling balls.
We ASSUME it is solid balls, but now do we know the inside isn't filled with a wooden tetrahedron instead?
>>713524259
162
>>713528159
Thank you.
>>713524259
This is the formula based on a tetrahedron:
n(n+1)(n+2)/6 = 165
>>713524259
When spheres of equal size are stacked into a pyramid with a triangular base, i.e., a tetrahedron, the number of balls on the bottom layer is n(n+1)/2, where n is the number of balls in the longest row along the base. The total number of balls in the pyramid is n(n+1)(n+2)/6.
n = 9
let t be the number of balls in the pyramid
t = 9(9+1)(9+2)/6
t = 9*10*11/6
t = 165
Q.E.D cucks
360
9 dolphins
>>713524259
Just count the layers and add the next row to the previous layer total and finally calculate the running total of all the layers 1 through 9
L1 = 1 (1)
L2 = L1 + 2 (3)
L3 = L2 + 3 (6)
L4 = L3 + 4 (10)
L5 = L4 + 5 (15)
L6 = L5 + 6 (21)
L7 = L6 + 7 (28)
L8 = L7 + 8 (36)
L9 = L8 + 9 (45)
---------------------------
Grand total = 165
>>713528947
that looks like normal old homework
>>713529092
look at the problems
>>713527029
I think you mixed up factorial (!) with summation (∑)

Depends on if the balls are in a square pyramid or a triangular pyramid.

Shouldn't that 9 be factored into the first parentheses rather than be multiplied straight across?
>>713531322

>>713532531
yeah I just finished CS 101, working on it
>>713532512
Figured it was... I feel sorry for you. And yes the algorithm is the same but is JavaScript it would be.
var total = n * (n + 1) * (n + 2) / 6;
Not your convoluted shit.
>>713532211
just for you:
def layer(n):
return 1 if n==1 else n+layer(n-1)
def total(n):
return 1 if n==1 else layer(n)+total(n-1)
print(total(9))
>>713524259
it would be very hard to count how many bowling balls are there. I'd say it's technically impossible. you would have to go around the world making a gigantic census and account for the balls that are being produced at any given moment. and what about the ones underwater or buried for whatever reason?
>>713533050
haha i'm just doing it recursively for fun
that same line in ruby is actually several less characters:
total = n * (n + 1) * (n + 2) / 6
balls are touching = GAY
>>713524259
Why the fuck does someone have that many bowling balls?! New fetish I haven't heard about?
165 - there are 9 stacks of 1, which is (9), 8 stacks of 2, which is (16), and 7 stacks of 3, which is( 21), and 6 stacks of 4, which is (24), and then 5 stacks of 5, which is (25), and then 4 stacks of 6, which is (24), and then 3 stacks of 7, which is (21), and then 2 stacks of 8, which is (16), and then finally, 1 stack of (9). take 9 + 16 + 21 + 24 + 25 + 24 +21 + 16 +9 and you get 165 bowling balls.
>>713524259
Those are not bowling balls.

>>713533882
even if you can do that (wich again, seems impossible) you won't be able to calculate the ones that have been destroyed and aren't there anymore.
