Question

last one. Using the ratio of perfect squares method, what is square root of 128 rounded to the nearest hundredth?

Answer 1

Just use calculator, What do you get?

Answer 2

11.31

Answer 3

thats it?

Answer 4

Yep.

Answer 5

i get it nowwwww!!!! Yaaay

Answer 6

its reaaaally easy

Answer 7

Just so you know, this is not how you use "ratio of perfect squares method."

But we are not really familiar with it, so yeah.

Answer 8

oh. crap. i failed my practice session. i got a forty%

Answer 9

just finish math homework and get over it haha

Answer 10

you got right on last two questions though?

Answer 11

i missed all three

Answer 12

Really? So 11.31 is not right?

Answer 13

it was 11.30 suuuuuper close

Answer 14

This is so wrong...

Answer 15

my thing is?

Must be because of some round up error.

Answer 17

maybe we really need to know this method, sorry for getting you wrong on questions.

Answer 18

its alright! thanks for trying to help me

Answer 19

@geerky42 I have never heard of that method either and I can not find this method on google.

Answer 20

Perhaps the op can tell us the method.

Answer 21

using the method is probably how they got 11.30 however the method is performed

Answer 22

I think @triciaal is familiar with it, she just did her work on OP's previous question.

We would like to know what this method is.

Answer 23

Currently idling lol...

Answer 24

\[11=\sqrt{121}<\sqrt{128}<\sqrt{144}=12\]
I know this

Answer 25

idk man. i just transferred from half a year of pre-al to Algebra senester 2

Answer 26

Given the equations 9x+34y=6 and 2x+12y=9, by what factor would you multiply the second equation to eliminate y and solve the system through linear combinations?

−43

−34

−32

−72 does anyone get this?

Answer 27

semester*

Answer 28

dude. make your own thread

Answer 29

Please don't post your question on other user's question. @Nieke

Answer 30

11+12=23
128-121=7
144-128=16

so what is 16/23=.6957
and 7/23=.30435

so somehow I think we suppose (somehow choose)
to say
11+.30435
11.30435
which rounded to the nearest hundredth is 11.30

Answer 31

oh by the way 16/23=.6957 and 7/23=.30435 we approximations

Answer 33

I think the method being talked about in this khan video may be the method

Answer 34

Could be it. It fits well.

Answer 35

did you figure it out? because im not really understanding this khan video
