This is part of the Fibonacci sequence. The next number is 21. Look at how much each number increases and the number before it.
1+1=2 (the number after 1 and 1)
1+2=3 (the number after 1 and 2)
2+3=5 (the number after 2 and 3)
So to solve we add 13+8=21
For light: Inverse Square Law
<span>
The signal is weaken by the inverse square of the
difference of distances this means that one over the square of the
difference. </span>
<span>
</span>
Therefore, 70000LY / 141 LY =496.45 and that
squared =246462.602 times less signal, or 1/246462.602.
2 For a circular telescope like the
Arecibo radio telescope that equals Pi times the radius squared. Sensitivity
of the telescope depends on its area.<span>
The new telescope needs 246462.60 times that area to have
enough sensitivity </span>
<span>
<span>(150 x 150 x Pi) = 70 685 sq m area for the Arecibo telescope
and that times 246462.60
= 1.74212 x 10^10</span></span>
<span><span>
</span></span>
What is the diameter of a circle with that area?
<span>
<span>1. Divide the area by Pi = 5.548156 x 10^9
2. Take the square root of the result to find the radius = 74485.94293</span></span>
3. Multiply by 2 to find the diameter =
<span>148971.886</span>
I'm not sure but I hope this helps

Answer:
20.424
Step-by-step explanation:
Given words can be written as
Eight and eighty-eight hundredths = (8+
)
= 
= 8.88
Two and three tenth = (2+
)
= 
= 2.3
Now multiply them
i.e 8.88 × 2.3 = 20.424
So 20.424 is the Answer
