We know that a doctor prescribes a 300-mg antibiotic tablet to be taken every eight hours. Just before each tablet is taken, 20% of the drug remains in the body.

We know that 20%=0.2.

We conclude that after the first pill, 300mg of the drug is in the body.

We have the following formula, to calculate how much mg of the drug is in the body after the second tablet:

$300+20\%\cdot 300=300+0.2\cdot 300=300+60=360$

So after the second tablet there is 360-mg of drug in the body.

We have the following formula, to calculate how much mg of the drug is in the body after the third tablet:

$300+20\%\cdot 360=300+0.2\cdot 360=300+72=372$

So after the third tablet there is 372-mg of drug in the body.

Jessica calculated the missing side length of one of these triangles using the Pythagorean Theorem. Which triangle was it?

Alenkinab [10]

Answer:

G

Step-by-step explanation:

We can find a missing length of a triangle using a Pythagorean theorem if and only the triangle is a right angled triangle.

The side of the missing length is:

a^+b^=c^

2^+4^=c^

4+16=c^

20=c^

$\sqrt{20} = c ^{2} \\ 4 \sqrt{5} = c$
