Use the following graph to answer questions 1 and 2. Write a ratio in simplified form of the vertical length to the horizontal length for the red triangle.
A. 2 : 3
B. 3 : 2
C. 1 : 1
D. none of the above

yes

step-by-step explanation:

yes

it would rotate about 180 degrees.

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.
