Answer:
Son's age is 25.
Step-by-step explanation:
Let the Father's age be 2x.
Let the son's age be x.
Five years ago:
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then:
2x - 5/x-5 = 9/4
⇒ 4(2x - 5) = 9(x - 5)
⇒ 8x - 20 = 9x - 45
⇒ -20 + 45 = 9x - 8x
⇒ 25 = x
∴ x = 25
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50 years
We are given square with side length l. The largest circle that we can cut from that square has diameter equal to that side. This circle is called inscribed circle.
When cutting circle from square paper we will be left with some extra paper. Area of that extra paper can be calculated using formula:
area_of_extra_paper = area_of_square - area_of_circle
Now we can insert formulas:

This is area of extra paper when we cut one circle. When we cut multiple circles we have:

Where:
N = number of circles
This formula is roughly:
In 565656 years Daniel will be 555 times as old as he's right now how old is he right now
Let x be his current age.
"In 565656 years" can be represented by the expression x+565656.
"Will be 555 times as old as he's right now" can be represented bas the expression 555x.
The whole question means that the age of Daniel in 565656 years will be 555 times his age now so x+565656 = 555x.
Solving this equation will find x, so his current age.
x+565656 = 555x
You subtract an x of each side, to have variables on a side, and numbers on an other:
565656 = 555x - x
565656 = 554x
You divide each side by 554
x = 1021.
So Daniel is currently 1021 years old.
