Answer:
Step-by-step explanation:
Let the required volume be x
<u>Use the ratio of gallon/volume to solve:</u>
- 1/0.13 = 20/x
- x = 20*0.13
- x = 2.6 ft³
With 20 gallons the scientist can cover 2.6 ft³ of water volume
Answer:

Step-by-step explanation:
Each term of this Geometric Series (3, −6, 12, −24, ...) can also be found through this explicit formula:
Because the
term is found by the product of its common ratio "q", times its predecessor n-1. Where n, refers to the order of the term.
So let's test it, suppose we want to find the 4th term. We know the common ratio and the first term. Then we can write f(n) as:

f(4)=f(3)*-2⇒-24=12*-2⇒-24=-24
The explicit formula is ok.
