Answer:

<h3>#4</h3>

Let M is the midpoint of DE.

Since D is at 8 and DE = 5.

DM = ME = 5/2 = 2.5

<u>Point M is at:</u>

  • 8 + 2.5 = 10.5          if E is to the right of D
  • 8 - 2.5 = 5.5            if E is to the left of D
<h3>#5</h3>

<u>Given</u>

  • XY = 7,
  • YZ = 2x - 1,
  • XZ = 30

<u>Since XZ = XY + YZ, set up an equation and solve for x:</u>

  • 7 + (2x - 1) = 30
  • 2x + 6 = 30
  • 2x = 24
  • x = 12
<h3>#6</h3>

The distance from your house to friend's is LN.

<u>We have: </u>

  • M is midpoint of LN, so LM = MN
  • LM = 3x
  • MN = 2x + 2

<u>Set up an equation, solve for x:</u>

  • 3x = 2x + 2
  • 3x - 2x = 2
  • x = 2

<u>Find the distance LM:</u>

  • LM = 3*2 = 6

<u>Find the distance LN:</u>

  • LN = 2*LM = 2*6 = 12

The table shows the height, in centimeters, that a weight bouncing from a spring would achieve if there were no friction, for a
Paha777 [63]
Hello! For ease of calculations, we can identify the time it took for the weight to bounce back to the other direction, then the other, and then back to its original position by looking at the time it took for the weight to change from 0 to 25 to 0 to -25 then back to 0. This is one whole cycle of the weight.

By the time the weight first reached zero, 1.5 seconds has passed. By the third time it got to zero again, 7.5 seconds has passed. Therefore, one whole cycle of the weight is 7.5-1.5 = 6.0 seconds.

ANSWER: One whole cycle of the weight took 6 seconds.
