Why the reasoning is wrong? He should have multiplied by 10? I'm not sure about the phrasing of: "since there are 9 layers of cubes below the top layer."

>>7085308
you have to multiply by 9 again. 63x9 would only get the surface area of one face of the cube

>>7085314
No, the little cubes are 1x1x1. The area of the top layer is 63 cubic inches. You don't have to multiply by 9 again.

>>7085318
63 in. x 9 in = 567 sq. in.
63 in x 9 in x 9 in = 5103 cubic in.

>>7085314
No, 63*9 is the volume under the top layer. They need to add in the top layer so it's 63*(9+1)

>>7085308
Yes. The student didn't include the top layer in the final count. The total volume is 630 in^3

>>7085326
The top layer has 63 1x1x1in cubes. Therefore, it's volume is 63 cubic inches. There are 9 (or 10, I still don't know) layers in total. Therefore, the volume is 63in^3 x 9 = 567 in^3.

Oh, cool. Thanks. I wasn't sure because English is not my first language. It was kinda hard looking for the mistake.

63 is a prime number and not a square. It's impossible to have 63 in the top layer. He must have counted wrong and it has to be 8x8 = 64

>>7085341
63 = 7*3^2

You must be feeling pretty stupid right about... now.

how fucking stupid are you?

>>7085339
No problem. I had a hard time looking for it and my primary language is English. Not including a single layer and describing it in easily overlooked language is definitely a standardized test trick.

The middle one is quite the semen demon.

the only one that was impossible was 7. the rest were fine.

That question doesn't even test math skills nor intelligence.

>>7085446
How the fuck normal, standard or whatever you want to call it math privileges white people? I fail to see the logic behind it.

>>7085258
Well, highschool girls are pretty dumb. What do you expect?

>>7085453
>I fail to see the logic behind it.
there might be a reason for that

>>7085453
Because whites are inherently smarter than niggers.

You're privileged because you're part of a group with a higher average IQ.

Children are children, we can't expect to teach them anything. This is basic child psychology....

>>7085446
How does the common core benefit minority students?

>>7085506
People think that by teaching kids to think instead of calculate they will be dumbed down to black levels.

>>7085505
HIgh school students are not really children.

>>7085509
Sorry, I didn't realize that /sci/ was brimming with subhuman racist filth. I have plenty of bones to pick with Common Core but that isn't one of them.

I got 2906914.5 dollars asuming that the number of sales increased is about half from the original and then it was pretty simple. It may be flawed and you have one assumption but common, it doesn´t mean it is fucking imposible, O did it in 3 minutes

Nigger, how new are you?

Btw, he was mocking racists you stupid jigaboo. God niggers are dumb.

>>7085453
Where the fuck do <span class="math">you[/spoiler] get off learning math when others don't want to and end up benefiting from it as a result? You're literally worse than Hitler.

Stop privilege now! Forced equality is what our founding father, Marx, always wanted! We can not allow motivated people to be able to get ahead by learning and working harder and using that to make their children better off.

>>7085514
The guy I replied to was mocking them, the posters I referred to sounded like Klansmen, and you just sound like an irreverent troll

>>7085506
Because calculus being designed by white people is clearly incomprehensible to minority. Removing it from the curricula will undo the unfair privilege they have as whites learning calculus.

The same can be said of all math topics really...

Because being smart is being racist! Check your privileges:

So privilege is a double-think word for some minorities clearly doing badly in some math courses? I´m not saying there is an iherent correlation between race and intelligent like uncle /pol/, but there is a clear corellation between poverty and intelligece.

>>7085551
>but there is a clear corellation between poverty and intelligece.
And since some minorities such as blacks are disproportionately poor, wherever they live in the world (America, Europe, Africa,...) this leads to the conclusion that....

>If you have ever studied geometry, you remember that by a course of reasoning, Euclid proves that all the angles in a triangle are equal to two right angles. Euclid has shown you how to work it out. Now, if you undertake to disprove that proposition, and to show that it is erroneous, would you prove it to be false by calling Euclid a racist? [Political Debates Between Lincoln and Judge Douglas.

>be black male who has been in gifted programs throughout his
> lack of diversity in gifted programs
> complete trash, misrepresenting black people and basically saying that we shouldn't have gifted programs because a lot of black people aren't valuing intelligence

I also forgot to mention that I don't think that we are inherently lazy and unintelligent. I do, however, believe that current black culture will only keep it people in poverty, and that real talent will always go unnoticed in black communities because of their devaluing of formal education. It's not the kids' fault, it's the parents' and other students fault, accusing black people of "acting white" for showing intellect.

>>7085556
>>7085556
That was my point nigger. It doesn´t mean that das racist or that you don´t expect then disproportionately different results in ap courses or advanced courses. Is it a problem? Yes of course, but math is math and you cannot change that.

holy shit if I have kids they're going to private school

>>7085579
>That was my point nigger
So you DO acknowledge that niggers are dumber?

>>7085556
...they were historically mistreated and started out poor, and are still poor because of low social mobility.

>>7085594
>...they were historically mistreated and started out poor
Yeah, it's not like the irish, the jews or the italians suffered the same...

>low social mobility
then why are chinese americans so successful? They were also treated like dogshit.

>>7085556
Plenty of poor people get PhDs

Black culture embraces niggerdom
White culture rejects white/trailer trash
The results speak for themselves

>>7085597
Chinks weren't subjected to sharecropping/redlining/repeated attempts by the CIA to destroy the role of the man in the black household by funneling all the extra drugs they got from drug cartels in the 70s and 80s

>>7085605
>Plenty of poor people get PhDs
How many of them are asians?

>Black culture embraces niggerdom
>White culture rejects white/trailer trash

Nigger thug culture sure doesn't help, but it's not the only reason for nigger school results.

>>7085597
I can't speak for other countries, but in America, blacks were treated like shit much longer than any other minority (besides Native Americans of course). Social mobility is low (there's some cultural issues as well), so they stay dumber and poorer. I imagine its similar for other nations as well. Jews are an anomaly though.

>Chinese Americans
The Chinese that come over here aren't just plebs off the street you know.

>>7085593
Well, yes, because they are poor
>>7085594
Yes, I know that I never denied it. But just because that you shouldn´t shit on well stablished subjects. Shit on arts and literature if you want and leave math and science alone.
>>7085597
Try to be fair, the irish and the jews and the italians weren´t product of the slave trade which were 80% hardcore criminals or war captures. A chink wasn´t a slave. It is all history and there is no reason to get all mad about that, but be fair so you don´t look as the oposite side of the coin as tumbler. It sounds stupid both ways.

>>7085609
>I can't speak for other countries, but in America, blacks were treated like shit much longer than any other minority (besides Native Americans of course)
Not american, but I get the impression that the Irish, Italians and Jews weren't exactly treated well either.

>Social mobility is low (there's some cultural issues as well), so they stay dumber and poore
If it's so low, why have the irish, italians, chinese and jews now joined the middle class?

>I imagine its similar for other nations as well.
Not really. France has no history of racial discrimination yet french niggers still perform poorly in school.

>Jews are an anomaly though.
Yes, they have an anomalously high average IQ.

>The Chinese that come over here aren't just plebs off the street you know.
I'm not talking about the recent H1B chinese. The chinese that came to work on the railroads weren't intellectuals, yet they prospered.

>>7085337
There's 10. It's the top row, plus 9 below. So 630 total.

>>7085613
>yeah i forgot about irish, italian and jewish slaves you fucking downie
Irish were literally slaves though. Italians and jews had a much tougher life in the slums of new york than the cushy existence of blacks in the agricultural south.

>prove it
prove what?

>>7085618
>Well, yes, because they are poor
Oh ok, I thought you meant the correlation in the other way (that dumb people are poorer than smart people)

>Try to be fair, the irish and the jews and the italians weren´t product of the slave trade which were 80% hardcore criminals or war captures.
Irish were quasi-slaves.

>A chink wasn´t a slave
He was a quasi-slave too.

>. It is all history and there is no reason to get all mad about that, but be fair so you don´t look as the oposite side of the coin as tumbler. It sounds stupid both ways.
All I know is that for the past 50 years blacks have received billions of dollars in financial compensation yet are still unable to improve their condition.

>>7085606
The CIA did try to subvert the civil rights movement but you can't keep on blaming their continued lack of achievement on that forever. Especially when other minorities and refugees come to America every year and quickly do better than black people.

Just look at this.

>>7085621
>Not american, but I get the impression that the Irish, Italians and Jews weren't exactly treated well either.
Sure, there was a time in the 1800s where all of these groups were discriminated against in the US. But none of them were ever slaves and none of them ever had to deal with jim crow laws. Blacks undoubtedly had it much harder much longer.

>If it's so low, why have the irish, italians, chinese and jews now joined the middle class?
Because they had more time to pull themselves up.

>Not really. France has no history of racial discrimination yet french niggers still perform poorly in school.
Can't really say anything about that.

>The chinese that came to work on the railroads weren't intellectuals, yet they prospered.
Not sure what you mean by "prospered." They did as well as any other industrial worker, sure.

>>7085635
>Italians and jews had a much tougher life in the slums of new york than the cushy existence of blacks in the agricultural south.
Because blacks weren't in slums in new york doing the same shitty jobs and doing hard labour in hot weather is a cushy existence right?

>>7085635
>>7085621
The Irish and Italians formed mobs. How do you think anyone gets ahead in New York?

>>7085594
>>...they were historically mistreated and started out poor, and are still poor because of low social mobility

Rehashed communist lies. Countless poor people work their way up from the bottom within a generation or two. Blacks are the only ones that choose to remain in the ghetto generation after generation and blame everyone else for their own bad life choices.

>>7085609
Republicans today want to place pikes with the heads of Mexican children on top at the border to scare them away. And yet they still manage to make it to the middle class. Meanwhile backs get endless amount of affirmative action support and go nowhere.

>>7085656
some of those countless poor people are black. but the vast majority of poor people remain poor, this applies to all races.

>>7085704
because they are immigrants. immigrants tend to have more drive than the average person, especially illegal immigrants.

>>7085711
Then clearly we should ship our blacks to Africa so they can get that immigrant drive

>>7085721
derp

forced immigration is not the same dickhead. someone who wants to immigrate to america legally has to jump through an enormous number of loopholes - those that manage it have high drive.

immigrating to america illegally requires putting yourself in danger, taking large risks, ponying up lots of money to unscrupulous people smugglers, etc. again, people who make it tend to have high drive.

>>7085747
>migrating to america illegally requires putting yourself in danger, taking large risks, ponying up lots of money to unscrupulous people smugglers,

Or getting on a plane and overstaying a visa.

>>7085759
gotta get the visa in the first place...

I did the whole test just now. I think it would be pretty difficult for 11 year old kids, which would be about 6th grade.
