Answer:

x=13 feet

Step-by-step explanation:

A ramp is between 1.96 and 1.80 feet, we will take 1.96

If R(x) =-0.05x+0.8x and R(x)=1.96 feet: we apply quadratic formula; \frac{-b+-\sqrt{b^{2} -4ac} }{2a}, where a=-0.05, b=0.8 and c=-1.96, so

\frac{-0.8+-\sqrt{0.8^{2}-4*(-0.05)*(-1.96) } }{2*(-0.05)}, solving x_{1}=13 ; x_{2} = 3,02; we take the highest value of x, x=13

Given: T is the midpoint of JK¯¯¯¯¯JK¯, JK = 5x – 3, and JT = 2x + 1. Determine the length of JK¯¯¯¯¯JK¯
Helen [10]
JK where T is the midpoint.   J >>>>> T >>>>> K. 

JK = 5x - 3
JT = 2x + 1

Because T is the midpoint, it means that  JT = TK
So, JT + TK = JK

(2x + 1) + (2x + 1) = 5x - 3
4x + 2 = 5x - 3
4x - 5x = -3 - 2
-x = -5
x = 5

JK = 5x - 3
JK = 5(5) - 3
JK = 25 -3
JK = 22

The length of JK is 22.

Answer:

  (b) angle FOA

  (c) angle EOA

  (d) angle AOH

Step-by-step explanation:

(b) The rays of vertical angles are opposites that form intersecting lines.

The opposite of ray OG is OF. The opposite of ray OB is OA, so the vertical angle to GOB is angle FOA.

__

(c) The opposite of ray OB is OA, so the supplement to angle EOB is angle EOA.

__

(d) Similarly, the supplement to angle BOH is angle AOH.

_____

<em>Comment on supplementary angles</em>

Angles that form a linear pair are supplementary. Angles do not have to form a linear pair to be supplementary. They merely have to have a sum of 180°. Here, the supplementary angles of interest do form a linear pair, so finding the other angle of the pair means only finding the other point that names the line being formed by the pair.
