What environmental pressures in the past do you think were the most important in shaping the human species that exists today?

OpenStudy (jdoe0001):

OpenStudy (anonymous):

what is the original unit?

OpenStudy (anonymous):

if it is measured in meters then the answer would be B and D

OpenStudy (anonymous):

yeah its meters

OpenStudy (anonymous):

the answer is B and D

OpenStudy (jdoe0001):

\(\large {\begin{array}{ccllll} mm^2&cm^2 \\\hline\\ 100&1\\ 2.535&x \end{array}\implies \cfrac{100}{2.535}=\cfrac{1}{x}\implies x=\cfrac{2.535}{100}\to 0.02535\ cm^2 }\) so...what do you think?

OpenStudy (jdoe0001):

did the cube change? did it shrink? did it enlarge? did it flip over? did it dance the watusi?

OpenStudy (anonymous):

is it b & d ? @jdoe0001

OpenStudy (jdoe0001):

dunno... look above.... those are the numbers in \(cm^2\) which is bigger? which is smaller? did the cube change because of that?

OpenStudy (anonymous):

*sighs* yes it is b and d... the unit was the only thing that changed but not the cube itself

OpenStudy (anonymous):

lol alright. thanks
