The time it takes for 1g of strontium-90 to decay to 250 mg is; 57.6 years
<h3>What is the half life of an element?</h3>
The formula for half life is;
A(t) = A₀ * (¹/₂)^(t/t_1/2)
Where;
A(t) is amount left after t years
A₀ the initial quantity of the substance that will undergo decay;
t_1/2 is the half-life of the decaying quantity.
We are given;
t_1/2 = 28.8 years
A₀ = 1 g
A(t) = 250 mg = 0.25 g
Thus;
0.25 = 1 * (¹/₂)^(t/28.8)
log 0.25 = (t/28.8) log (1/2)
-0.60206 = (t/28.8) * -0.3010
t = 2 * 28.8
t = 57.6 years

<u>Answer:</u>
<em>We have to determine the pattern of numbers followed in the sequence 2, 7, 8, 3, 12, 9.</em>
<em>Do a grouping of the sequence into two groups. Let the first group be 2, 7, 8 and the second group be 3, 12, 9
</em>
<em>
There is a difference of 1 in the pair 2 and 3, a difference of 5 in the pair 7 and 12 and a difference of 1 in the pair 8 and 9
</em>
<em>
This means there would be a difference of 5 in the next pair.
</em>
<em>
So, adding 5 to the first number to the third pair.
</em>
<h2><em>
Hence, the next number will be 13.</em></h2>
