Nola hiked down a trail at a steady rate for 10 minutes. Her change in elevation was -200 feet. Then she continued to hike down
DedPeter [7]

The <em><u>correct answer</u></em> is:

The faster rate is when she hiked down 200 feet in 10 minutes.

Explanation:

The rate of change is given by the change in y over the change in x; in this case, the change in elevation over the change in time.

For the first part of the hike, the change in elevation was -200 and the change in time was 10; this gives us a rate of change of -200/10 = -20.

For the second part of the hike, the change in elevation was -300 and the change in time was 20; this gives us a rate of change of -300/20 = -15.

She hiked downhill faster during the first part of the hike, at 20 feet per minute.

Please explain urgent! Brainly to anyone who can answer!
Wittaler [7]

Answer:

  • JK ≈ 6.86 units

Step-by-step explanation:

According to the diagram MK is the angle bisector of  ∠LMJ in the triangle LMJ.

Use angle bisector theorem, which states:

  • <em>an angle bisector of an angle of a triangle divides the opposite side into two parts that are proportional to the other two sides of the triangle.</em>

<em />

Applied to the given triangle, the ratios are:

  • LK/JK = LM/JM

Use segment addition postulate and substitute known values to get:

  • (LJ - JK)/JK = LM/JM
  • (14 - JK)/JK = 50/48
  • 50JK = 48(14 - JK)
  • 50JK = 672 - 48JK
  • 50JK + 48JK = 672
  • 98JK = 672
  • JK = 672/98
  • JK = 6.86 (rounded)
