2 f t → t
3 t t → t
4 f f → f

180 square centimeters

step-by-step explanation:

x = 3 ± √(5+y)

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

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.
