1/8 of the original amount remains.
Approx 1/8 will remain.
equivalent fraction of three fifths = 6/10
4/10
Three tenths is .3 as a decimal.
1/8 of the original amount remains.
After three half-lives, only 1/8 (or 12.5%) of the original radioactive sample remains. This is because each half-life reduces the amount of radioactive material by half, so after three half-lives, you would have (1/2) * (1/2) * (1/2) = 1/8 of the original sample remaining.
An eighth remains.
If I take a radioactive sample of 400 moles of an unknown substance and let it decay to the point of three half-lives I would have 50 moles left of the sample. 1/2 of what is left will decay in the next half-life. At the end of that half-life I will have 25 moles left of the unknown substance or 4/25.
Approx 1/8 will remain.
Not sure what you mean by "had-lives". After 3 half lives, approx 1/8 would remain.
There are three models of a fraction namely area model, liner model and set model.
Not sure what you mean by "had-lives". After 3 half lives, approx 1/8 would remain.
Three half lives have elapsed. This can be determined by calculating how many times the original sample size must be halved to get to one eighth: (1/2) * (1/2) * (1/2) = 1/8.
Radioactive substances can emit alpha particles, gamma radiation (gamma rays) and beta radiation (beta particles). What they do not emit is delta radiation.It causes transmutation.It has a mass of 4 amus.
It takes one half-life for half of the radioactive sample to decay. Since half of the sample has decayed after 16.5 hours, it will take another 16.5 hours for the remaining half to decay, totaling 33 hours to decay three fourths of the original sample.
5/12 of the pizza remains.
