Step-by-step explanation: Taller people have been shown to have bigger feet.  It's how humans are engineered.  Your feet have to support your entire body while also providing balance.  Larger feet help taller people keep their balance because the pressure is distributed among a larger surface.  Sure some people may have smaller feet even though they're tall, but that doesn't mean a majority of tall people have small feet.  

A

Step-by-step explanation:

I took the test

d

step-by-step explanation:

d

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
