Amedication is administered with a dose of 10 milligrams. after 3 hours there are 6.5 milligrams in the patient's system. what is the half life of the medication, in hours? round to one decimal place.

The half life of the medication, in hours is 2.3 hours

Solution:

Half life of medications means the time in which the medication become half of its original value i.e. From 10 milligrams to 5 milligrams

The time in which medication become 6.5 milligram  is 3 hours

To become 1 milligram the time taken will be 3 divided by 6.5

So, the half life time [5 milligram] will be, time taken for 1 milligram multiplied by 5

Thus it takes 2.3 hours for half life of medication

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
