Ответ:
Natural disaster does the green circle mean
Ответ:
75% of the material has decayed.
Explanation;
We can start this problem by solving the first half-life assuming the arbitrary condition stating that the initial concentration has a value of 100M, thus, for the first half-life, the concentration dwindles to 50M. Afterwards, the second half-life yields a concentration of 25M, meaning that the 75% of the material has decayed up to the second half-life, of course, the half of the result from the first half-life.
Hope this helps! :)
