Which graph shows the solutions to the inequality ?

The first one

Step-by-step explanation:

When u have a < symbol with a line under it ur circle on the number line has to be filled in. Make sure u put this dot on the number that is in the equation The graph line, again, points whichever way the "arrow" of the symbol is pointing.

answer: this is not a question

step-by-step explanation: this is a answer

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
