This is hard

[Sillysidley]

1. What is the arithmetic mean, expressed as a common fraction, of the solutions to|10x|-sqrt(10x)=0

2. Triangle ABC is such that AB=8, AC=9, and BC=10 cm. The bisector of the interior angle BAC intersects BC in a point M. What is the length of the segment BM? Give you r answer as a common fraction in lowest term.

These are tricky. I have worked on them for hours, and don't know what they are.:dry:

If anyone wants interesting problems tell me. ( I kow the answers to those:lol: )

[Mr. Hui]

Interesting problems. I'll solve them and post a solution. :cool:

[Sillysidley]

Here is a test I scored 10 on, then 19, and then 26. The 2 problems from before r from here:whistle: :lol:

[Sillysidley]

will anyone solve these problems?

[Alex a.k.a whiteboy]

idk and i hope i do lol:D :D MAKE ONE EASY!!!

[Sillysidley]

these r hard

[Alex a.k.a whiteboy]

...i ..uhh know..thats why i said make one easy!!!:o :o :o durr lol:lol: im jk

[Sillysidley]

what's (1+1)^-1

Easy enough

[Alex a.k.a whiteboy]

uhhh is it -1

[Sillysidley]

no, 1/2

[Mr. Hui]

(1+1)^-1 = 1/2 <- Correct

[Alex a.k.a whiteboy]

mann then what is ^?

[Sillysidley]

mann then what is ^?

^ is " to the power of"

Mr. Hui, what is this?

If anyone wants interesting problems tell me. ( I kow the answers to those:lol: )

1. The answer is 1/20, because 10x must be 0, or 1.

[Alex a.k.a whiteboy]

umm is number two 11?

[Sillysidley]

I don't know the answer...:lol: :icon_xd: :dry:

but thats wrong anyway because it's not a common fraction

[Sillysidley]

i bet u can't even figure out what the negative reciprocal of 500 is...:lol:

will anyone answer #2? The answer to the first is 1/20

[Alex a.k.a whiteboy]

the negative?? wouldnt it be -1
___
-500?
lol i tried to get it like a problem set-up

[Sillysidley]

the ans is -1/500

a reciprocal of a number is the number that when multiplied by the number is 1

[Scion]

lets get on with the second problem somedude this is your homework is it okay to post homework here Mr.Hui

[Sillysidley]

of course it is:angry: I think:lol: :confused:

[Sillysidley]

i was right!!! And nobody ever answered any of the 2 questions:angry:

[Scion]

the asnswrer is in the mmpc

[Sillysidley]

really? which one?

[lizzien]

somdude on page 2 how did you get to make 2 to the 3rd power?

[Sillysidley]

I don't know why mr. hui posted that, i didn't say that?

[kickonlanky]

ok read this

1. Suppose 4 days before the day after tommorow was Thursday. What day of the week was yesterday?
2.a gruop of 24 college students decided to climb Mt. McKinley. They bruoght enough food to last 20 days. If 16 additional students jion the team, how many days will their food last?
please help its do Mon.:icon_crying: :icon_crying: :icon_crying:

1) uff, my minds running a bit of blank when it comes to absolute values. So I really dont think this is correct, but I got .1 and 0 for my answers. Checking them it works, but I still dont really know.

2) sorry broski, dont remember anything from geometry.

[Sillysidley]

i had already gotten 1, and it's the same as yours

i need help on 2

[Temperal]

Two equations would be (With BM as x and AM as y):
tan 90=y/x
y^2+x^2=8

Would that help?

[Temperal]

Or the second equation could be y2+x
2=8, as Mr. Hui said earlier. :lol:

so easy 1st one s monday second is 24 times 20=480 so 24+16=40 thatmeans 480/40=12 wow thats easy

[Temperal]

Would you mind if I say it's been answered a million times already and that it would be nearly two months overdue answered now?

[Scion]

no i wouldnt mind

[Sillysidley]

Nice time to answer it... :lol: :rolleyes:

[Scion]

uh i wish there was something that would allow you to lock a thread after question has been answered preventing spamming just an idea:cool:

[Temperal]

That's insulting!

[Scion]

no its not they do it in some websites u know

[Temperal]

I mean you suggesting that while we were posting, thus implicating we are spammers. :angry:

[Scion]

posted what?

[Temperal]

I MEAN, you suggesting the rule while inresponse to us posting! That's insulting!
