a scuba diver has a taut rope connecting the dive boat to an anchor on the ocean floor. The rope is 110 feet long. The water is 55 feet deep. To the nearest tenth of a foot, how far is the anchor from a point directly below the boat?

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

i saw this question before, dont know the asnwer srry

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.
