Two numbers add up to 247 and the first is 27 bigger than the second. what are the two numbers?

x + y = 247  

x + (x + 27) = 247  

x + y = 247  

2x +27 = 247  

x + y = 247  

2x = 247 - 27 or 227  

x + y = 247  

2x = 220  

x + y = 247  

x = 110  

110 + y = 247  

y = 137  

110 + 137 = 237

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
