Evaluating the given sequence, it is evident that the next number is twice the number prior to it. Thus, the given is a geometric sequence with first term (a1) equal to 1 and common ratio of 2. The geometric series may be calculated by the equation,
Sn = a1 x (1 - r^n) / (1 - r)
where Sn is the sum of n terms in this case, n = 11.
Substituting the known values,
<span> Sn = 1 x (1 - 2^11) / (1 - 2) = 2047
</span>
Thus, S11 is 2047.
Step-by-step explanation:
I think B or F is the best answer
So, she buys 16 bags, each of them weights

pounds.
to find how many pounds of soil she bought, we have to multiply:
16*

=//16 is equal to 8*2, so we can simpify:
2*

which is 2*5=10
so in the end she bought 10 pounds of soil!
I think it is the first one: Different bar widths.
