Find the area of the composite figure.
15.3 mm
186.66
236.60
286.22
288.62

the radius is 2 times the diameter.

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

good luck on ur quiz test or homework. have a good day : )
