on the blueprint of the house 44 millimeters represents 8 meters. the length of the living room is 33 millimeters on the bluepri
Scilla [17]
So if 44=8 and 33=x, solve for x. 
The problem would look like this : 44mm = 8m
                                                      33mm =  x
You would cross multiply giving you this : 44x = 264
Then divide 264 by 44 to isolate x, then you should get this : x = 6
6m will be your answer.

Please help me asap i will mark a branlist number 7
SVETLANKA909090 [29]

Answer:

When doing square roots the opposite is squaring so, to find one that is more than 12 and less that 13 would be finding one that is in between √144 and √169

That leaves your answer as √150, because it is more than √144 (which is 12) and less than √169 (which is 13)

B √150

Hope this helps ;)
