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%

Step-by-step explanation:
Answer:
Only 1st option Negative three-fourths divided by Negative two-thirds has positive quotient.
Option A is correct.
Step-by-step explanation:
We will solve to find out Which expression has a positive quotient.
We know the division rule: 
and 
We will use these rules
1) Negative three-fourths divided by Negative two-thirds
The quotient is positive.
2) Negative StartFraction 1 over 8 EndFraction divided by 3 and one-fifth
The quotient is negative.
3) 2 and StartFraction 2 over 7 EndFraction divided by negative one-fifth
The quotient is negative.
4) Negative 6 divided by Five-thirds
The quotient is negative.
So, only 1st option Negative three-fourths divided by Negative two-thirds has positive quotient.
Option A is correct.
