f(6) = 1+2+4+8+16+32 = 63
f(7) = 63 + 64 = 127
This is a geometric sequence where r the common ratio = 2.
f(n) = a1 * (r^n - 1) / (r - 1)
here a1 = 1 and r = 2 so
f(n) = (2^n - 1) / (2 -1)
= 2^n - 1.
When n = 64 ( the last square on the chess board)
f(n) = 2^64 - 1 = 2^64 ( I think we can neglect the 1!!)
That is the total number of grains of rice.
In tons of rice this is 2^64 / (25,000 * 2000)
= 3.689349 * 10^11 tons approximately.
So for each person the amount of rice would be 3.689349 * 10^11 / 6 * 10^9
= 61.5 tons approx. (Answer).
The angle 5x will be 50⁰. Then the correct option is D.
<h3>What is a parallelogram?</h3>
It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.
The diagram is given below.
We know the sum of internal angles is 360 degrees.
Then we have
5x + 130 + 5x + 130 = 360
10x = 100
x = 10
Then the angle 5x will be
5x = 5(10)
5x = 50⁰
Then the correct option is D.

Any fraction that can be simplified to 1/4 would work. I don't have a model to shade, but I can give you some examples. 2/8, 3/12, 4/16, 5/20... I hope this helps!
C. -2° :) hope this helps lmk!
The point slip form would be: y+8=16(x-8). Not sure if that’s what you were looking for.
