Given that the central angle of a polygon is 18, then the number of sides of the polygon will be:
360/18
=20 sides
thus the side length will be:
144/20
=7.2 ft
hence the area will b given by:
p=s×n
a=s/[2tan(180)/n]
where:
Area=(a×p)/2
p=perimeter, s=side length, n=number of sides
p=7.2×20=144
a=7.2/[2tan (180/20)]=22.73
thus
A=(144×22.73)/2
A=1632.524 ft²
The 5 in the hundredths place represents 5/100, whereas the 5 in the tens place represents 50, Figure out how 5/100 and 50 are related to each other: (5/100)x = 50. Mult. both sides by 100, we get 5x = 5000. Thus, the 5 in the tens place is 1000 times the 5 in the hundreths place.
Hey there!
Apply fraction cross multiply: if a/b = c/d , then a *d = b*c
2 ( 5x - 2 ) = ( 2x + 4 ) * 4
expand : 2 (5x-2 ) => 2*5x - 2*2 => 10x - 4
expand : ( 2x +4 ) * 4 => 2x * 4 + 4*4 => 8x + 16
10x - 4 = 8x+16
add 4 to both sides:
10x-4+4 = 8x+16+4
simplify :
10x = 8x + 20
subtract 8x from both sides:
10x -8x = 8x+20-8x
simplify:
2x = 20
Therefore:
x = 20 / 2
x = 10
Hope that helps!
Let Alex (the youngest) be n
Sam is n+3 because he is three years older
George is n+5 because he is 2 years older than Sam (n+3 +2) = n +5
All their ages summed = 35
So
n + n +3 + n + 5 = 35
Combine like terms
3n + 8 = 35
<u> - 8 -8 </u> subtract 8 from both sides of the equation
<u>3n </u> =<u> 27</u>
3 3 divide both sides by 3 and get n= 9
So Alex is 9
Sam is 12 since he is 3 years older than Akex
George is 14 since he is 2 years older than Sam
9 + 12 + 14 = 35
