Answer:
There are 2,000 grams left after 300 years.
Step-by-step explanation:
Giving the following information:
The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially.
<u>First, we need to calculate the reduction of the substance each year:</u>
Yearly reduction= 8,000/400= 20 grams per year
<u>Now, for 300 years:</u>
300 year reduction= 20*300= 6,000
There are 2,000 grams left after 300 years.
Change 3 and 15/44 to an improper fraction: 3 x 44 + 15 = 147 So, 147/44
times the whole number (3) by the bottom number of the fraction (44 or denominator) then added the top number (15 or numerator). Once you get that number you put it over the original denominator in the question (44).
then you divide the two number so... 147/44 = 3.340909091 <- That's your answer!
