The zebra mussel, Dreissena polymorpha, filters particulate organic carbon (POC) from water as
part of its feeding pattern. The concentration, c, of POC (in milligrams per liter) remaining in a
particular bay m months after the introduction of a population of zebra mussels can be
estimated using the following equation,
c=0.4.0.9"
According to this estimate, how many milligrams per liter of POC were in the bay when the
zebra mussels were first introduced?

because 1.2 isnt half of 6 duh

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
