The half-line of a radioisotope is the amount of time it takes for ? a. the age of an artifact to be calculated. b. half the sample to decay. c. detectable radiation to be absorbed by a sample. d. all the sample to decay

(b)The half-life of a radioisotope is the amount of time it takes for the amount of time it takes for half the sample to decay.

A radioisotope decays and changes to an alternate element at a consistent rate. The rate is estimated in a unit called the half-life. This is the time span it takes for half of a given measure of the radioisotope to decay. This rate is dependably the same for a given radioisotope.

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)
