A tent has a square floor that measures 9.6 feet on each side. There is a 10-foot zipper in the center of the front panel of the tent that runs from the top of the tent to the floor. The tent has a center pole for support. What is the length of the center pole to the nearest tenth of a foot?

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

0.50 , 0.75

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.
