something.....................
Folding a paper will make it thickness become double from it before.
Unfolded paper has 1 thickness
1 times folded paper has 2 thickness
2 times folded paper has 4 thickness
3 times folded paper has 8 thickness
From here it is clear that the pattern is

. SInce the paper is 0.1mm, then the function would be:
f(n)=

x 0.1mm

4.24 to two decimal places
Answer:
25 in ^2
Step-by-step explanation:
First find the area of the circle
A = pi r^2
A = 3.14 ( 4.3)^2
A =58.0586
The take the fraction of the circle that is shaded
A circle is 360 degrees
155/360
155 /360 * the total area = area shaded
31/72 * 58.0586 = 24.99745278 in ^2
Rounding yields 25 in ^2
Answer:
x = 13
Step-by-step explanation:
y=50
50 = 5x - 15
50 + 15 = 5x
65 = 5x
65/5 = 5x/5
13 = x
