Which of the following could be used to calculate the area of the sector in the circle shown above? a
π(8in) (42 over 360)

b
π(42in) (28 over 360)

c
π(42in) (8 over 360)

d
π(8in) (242 over 360)

your answer would be 12

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.

answer: the answer for that is 22/3
