Tricia measured the snow falling and ledge on her window. in 30 minutes the snow increase from 1/4 inch to 3/4 of an inch. by how many did the snow increase? a) 1 inch b) 1/4 inch c)1/2 inch d)3/8 inch

Hello!

To find the increase in depth, we must subtract the initial depth from the final depth. This can can be represented by the following formula:

(change in depth) = (final depth) – (initial depth)

Insert any known values into the equation above and simplify:

(change in depth) =  – 
change in depth = 

We have now proven the change in depth to equal . We know, however, that this fraction can be reduced to a value of . Therefore, the answer to this problem is C.

I hope this helps!

The scale factor of what ?
