Suppose a small quantity of radon gas, which has a half-life of 3.8 days, is accidentally released into the air in a laboratory. if the resulting radiation level is 40% above the safe level, how long should the laboratory remain vacated? (hint: to start with, determine what fraction of the "resulting radiation level" is the maximum safe level.) the laboratory should remain vacated for how many day?

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

answer: sorry i can't you.

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

the answer is mp
