I think it is D. 6
If there are 100 file folders all 0.45 inches thick, then the combined thickness of the folders is 45 inches. Each drawer can’t hold more than 7.5 inches. So you divide 45 by 7.5. This gives you 6.
The explicit rule for this geometric sequence 29,23,2,6, is n = 29 × (29/23)^(n - 1)
<h3>How to write explicit rule</h3>
Second term, a×r = 23
23 = 29 × r
23 = 29r
r = 29/23
The explicit formula is given by
nth term = ar^(n - 1)
n = 29 × (29/23)^(n - 1)
Where,
nth term = number of terms

Answer:
90(Initial Weight) + <em>W*t = 138 Kg </em>
So the Weight increased per month is 6Kg
Explanation:
The Wrestler started at 90Kg weight
After 8 months, Wrestler had a weight of 138Kg.
The weight gained by the wrestler in '<em>t'</em> months is:
138(Kg) - 90 (Kg) = 48 (Kg)
From above equation we can see that a difference of 48Kg was attained by Wrestler.
Since the question stated that, the weight increased at a constant rate, so we can calculate the weight gained each month over a period of 8 months.
Weight gained per month: 48 (Kg) / 8 (Months) = 6 (Kg) / (Month)
So now we can write the equation in terms of <em>W</em>(Gained per month) and<em> t</em>( t number months)
The equation becomes:
90Kg (Initial Weight) + <em>W.t = 138 Kg </em>
<em>( where 'W' is Weight increased per month and 't' is number of months passed)</em>
