200 is the answer

- anonymous

xlog12=log215
divide both sides by log12
x=log215/log12
so the answer is:
x=2.161303737
or rounded to the nearest tenth, it would be:
x=2.2

- anonymous

That would be to the nearest hundred @Bhim

so its 2.2?

Heh, @AlexPR787 I don't get it, I think the question is simpler, 215 to the nearest hundredth is 215.00, there are no fractional values for this. @coolaidd Can you clarify the question?

- anonymous

sorry let me explain

- anonymous

its 200

- anonymous

I think there is a misunderstanding: hundredth is http://en.wikipedia.org/wiki/Hundredth

- anonymous

thats the question..

- anonymous

it is 200

- anonymous

Rounding 215 to the nearest hundred would yield 200, but rounding it to the nearest hundredth would mean 215.00, because there are is no fractional part to the value

- anonymous

so the answer would be?215.00

- anonymous

Well, I'm wondering if the question may actually mean, what is 215 / 100, to the nearest hundrdeth

- anonymous

*hundredth

- anonymous

is that the only thing the question says?

- anonymous

(1.) If the question is merely, what is 215 to the nearest hundredth, then the answer is 215.00
(2.) If the question is actually seeking, what is 215 divided into 100 parts, 215/100, then what is the value of each part rounded to the nearest hundredth, then you have 215/100 = 2.15, so to the nearest hundredth is 2.15

- anonymous

just put 2.2

- anonymous

No, that would be to the nearest tenth

- anonymous

log_5 (2x-5) =-4
2x - 5 = 5^(-4) = 1/625
2x = 5 1/625 = 3126/625
x = 1563/615

- anonymous

is this correct?

- anonymous

well, for that, yeah, looks right

- anonymous

yeah

- anonymous

do i finish 1563/615?

- anonymous

If you need to, like if the question requires you to find the answer to the nearest anything

- anonymous

i got 2.54146341.. what would that be rounded to the hundredth?

- anonymous

OK, so you want to round to the nearest hundredth, this means you need to consider the value of the thousandth, which is the number in the 3rd decimal place. This requires remember the rules for rounding. If the value in the 3rd decimal place is less than or equal to 5, then you round down, and do nothing to the hundredth value. If the 3rd value is greater than 5, then you round up, meaning you add a one.
so if
\[2.541\] then round down because of the 1, it's called rounding down because \[2.54 < 2.541\]
so if
\[2.546\] then round up because of the 1, so \[2.546 becomes 2.54 + .01\] it's called rounding up because \[2.55 > 2.541\]

- anonymous

so its 2.541?

- anonymous

to the right of the decimal point you have
[tenths, hundredths, thousandths, ten thousandths...]
You want to find your answer to the nearest hundredth, so, yes, look at 2.541
The value in the thousandth place is 1, do you round up or down?

- anonymous

down?

- anonymous

?

- anonymous

Yep, and why ?

- anonymous

because its below 5?

- anonymous

right

- anonymous

so 2.541 is right or do i have to do more to it

- anonymous

Hehe, you have to make to the nearest hundredth, you still have a 1/1000 in there ;)

- anonymous

so how would it look?

- anonymous

?

- anonymous

OK, you want the value with only the hundredth value as the smallest, you want to disregard the other values to the right of the decimal. So, like all the other examples, you would only keep the 2 values to the right of the decimal, so if you have 1.241, you would have 1.24 as the answer if you wanted it to the nearest hundredth....so 2.541 to the nearest hundredth is?

- anonymous

2.54?

- anonymous

Yes, exactly
