Answer:
40.4%
Step-by-step explanation:
Given data
Initial depth= 5feet
Final depth= 5-3.2+6.6= 8.4feet
Hence the percent change
% change= FInal-initial/final*100
% change= 8.4-5/8.4*100
% change= 3.4/8.4*100
% change= 0.404*100
% change=40.4%
Hence the percent change is 40.4%
1.x=1 y=5
2.x=0 y=1/4
Since the simplest form of the fraction 12/42 is 2/7, the simplest form of the ratio 12:42 is also 2:7.
the answer will be 5.
