You should be able to solve this

230

360-90-40 That sure was hard

>>100778517 360-(90+40)=230

This is so basic that actually answering that would make one look like an idiot.

90 (you didn't say which angle hahaha)

>>100779241 Also, sage for poor attempt, and possibly that OP is underaged.

that counts as a question?

>>100779513 360-90+40 = 360+40-90 answer is 310.

How about this?

360 - 40- 90 = 230. Give me a hard one faggot.

>>100778517 360, it says it right there on the board. Don't argue with sensei now, he knows what milk for me to drink.

>>100779770 I'm fairly certain data is missing. Or not, I suck at "situations" like these.

>>100779740

>>100779770 Impossible with the given information.

>>100779844 yeah, data is missing. Like the time she started running for example.

>>100778517 You should be able to solve this.

>>100779905 Wait a minute.

>>100779967 The answer is fourteen. There are fourteen candles in that picture.

>>100779905 Umm, what?

>>100778517 42

>>100779844 You're correct, you need the distance from the house to the park to be able to solve this.

>>100779967 Pi.

>>100779905 0 = 26

>>100779647 >tfw no one wants to solve your post I geddit, must be too hard for you huh /a/?

>>100779905 x - 7 = 19 + x x - x = 19 + 7 x = FUCK YOU

>>100780040 False.

>>100780040 You know that shit doesn't make sense..

>>100780045 Clearly 5 pieces.

>>100780045 Fucking Kagetsu Tohya. It's impossible to win. I still didn't get the Ren scene.

>>100780045 Assuming how they ran out of money they had to pay with cream pies I'd say 5

>>100779967 What's the question? Why are there random chemical structures amongst the math equations? They don't even look like they'd have anything to do with quantum or physical chemistry.

>>100779905 I don't remember how was this called, but the aswer is that (x-7) isn't equal to (19+x). The reason is that there isn't a point where this 2 lines ( y = x-7 and y = x+19) cut because they have the same slope.

>>100780026 and an actual speed

>>100779647 P= (A+2B)/3, Q=(B+2C)/3, R=(C+2A)/3. P+Q+R = A+B+C Centroid of triangle ABC = (A+B+C)/3 Centroid of triangle PQR = (P+Q+R)/3 = (A+B+C)/3 QED

>>100780120 It's actually not that hard to just "win". Getting some scenes require use of the flowchart, and manually deleting your flags savefile without deleting the galleries though.

>>100780244 I dont think it works with (+) and (-) It only works with (x) and (:)

>>100780040 I see clearly now.

>>100779905 The equation is correct in modulo 26, which means it might be connected to Cryptography.

This is as far as I made it in Engineering before switching majors.

>>100780489 7x and 19x would have 1 point where they cross each other

>>100779740 sure here

>>100780567 The equation is still not correct and it's a mistake. Right after this a student calls him out on that and he corrects it.

>>100780489 >I dont think it works with (+) and (-) Exactly, it would only work if it was like: 7x= x/19 As you said or if it was like: -x-7=x+19 Where they have different slope.

>>100780712 Yes.

>>100780712 Was this ever solved?

>>100780741

>>100780622 I know, but they can't be 7x and 19x since x - 7 = 19 + x (-x) - 7 = 19 + (-x) or x - 19 = 7 + x You can only swapping shit

>>100780812 no. i think it drove one person insane because he coulnd't solve it

>>100780815 It all makes sense now

>>100780712 I don't even what is it trying to ask.

>>100780712 I fail this class twice

>>100780815 shit, hidden agenda

>>100779740 >Give me a hard one Oh lewd.

>>100780968 The Riemann zeta function ζ(s) is a function whose argument s may be any complex number other than 1, and whose values are also complex. It has zeros at the negative even integers; that is, ζ(s) = 0 when s is one of −2, −4, −6, .... These are called its trivial zeros. However, the negative even integers are not the only values for which the zeta function is zero; the other ones are called non-trivial zeros. The Riemann hypothesis is concerned with the locations of these non-trivial zeros, and states that: The real part of every non-trivial zero of the Riemann zeta function is 1/2 good luck

>>100781212 Who the fuck is Riemann

surely, you can spot the mistake here, /a/

>>100780777 Except it is x-7, not -x-7.

>>100782011 Someone already posted the aswer.

>>100781911 Make an option E with 20% as the answer.

>>100781911 33%

>>100780712 I wonder how many will get this

>>100782140 >>100782220

>>100782140 Also, the answer to this one would be: 25%

>>100782284 How is 33% wrong?

>>100780712 Solved.

Is this Reality or are we just part of a Boltzmann brain?

>>100781911

>>100783584 >>100783642 Oh no, i fucked up :(

>>100783613 It's C. The answer is constantly changing so you can never get it right. Therefore the answer is 0%.

>>100781911 0%, because I can't choose 33%

>>100781717 0=/=26 x is undefined

>>100783539 Does it want the area of the shaded area?

>>100783687 Doesn't that mean that you could also always be right?

>>100779786 This, fucking idiots.

>>100783814 No, because if you pick the answer as C to be right you did not pick at random. The problem is only unsolvable if you pick randomly.

>>100783338 Not if I make it say 1/2 instead of NaN Not even matlab? It does all sorts of nifty things

>>100783860 The random is only hypothetical. >>100783814 No.

Because trains are too easy.

>>100783395 >implying we are still at middle school. Tell me, what do I need this shit for in Law or Medicine?

>>100780470 That doesn't make sense anon. What are A, B, C, supposed to stand for? If they stand for either X or Y coordinates than your solution doesn't work. Check it for a simple right triangle with vertex at (0,0) and legs equal to 3.

>>100786613 So B is traveling towards A at 0.9c and A fires something directly at B? It hits at ((0.2)+(0.9))/(1+(0.2)(0.9)) with a velocity going towards B, whatever sign that supposed to be.

>>100786839 I see that your "intellectually high tier field of study" didn't catch my hypothetical question. >implying I am in those fields AT ALL

>>100786843 Speed is a scalar, it just describes the magnitude Eg: you are driving 50 miles per hour, the rocket is traveling 600 miles per hour Velocity is a vector, it describes the magnitude and direction Eg: you are driving 50 mph East, the rocket is traveling 600 mph upwards

>>100785473 x(0) => x * 0 => 0

>>100787022 Why don't they just call it "vector speed" or "directional speed" then?

>>100786900 If they're the x or y coordinates than the solution is wrong though. Also, I've never seen triangles vertices described like that.

>>100786827 Correct. >>100786843 Seems speed is sign-less, and probably equals velocity's module.

>>100787222 I'm stupid, it should be 110c/118. The decimal expression is right though.

>>100787109 It saves time, and when you're doing physics/engineering you're almost always dealing with vectors anyway >>100785473 That's why you can't divide by zero

>>100784312 Incorrect, nothing can travel faster than the speed of light. If you have two ships approaching eachother with each ship traveling at 0.6c, the relative speed of one ship as it appears to the other will still be smaller than c.
