Answer: 4
Step-by-step explanation:-------------------
The half-life is 29 years.
116 : 29 = 4
So we will have 4 periods of half-life:
( 1/2 )^4 = 1/16
150 g * 1/16 = 9.375 g
Answer:
9.375 g of strontium -90 will remain after 116 years.
1 because 1 times 1 times 1 equals 1
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequenceby 33 gives the next term. In other words, an=a1⋅rn−1an=a1⋅rn-1.
