The snowboarder went off a jump and did a 180. In which direction was the snowboard facing when he landed? How do you know?
dem82 [27]

Answer:

The snowboard was facing the opposite direction from which it started the jump.

Step-by-step explanation:

You may not have learned this yet, but a 360 degree turn makes a complete rotation. Knowing this, 180 is half of 360. This means that the snowboard made a half-way turn. Therefore, it is facing the opposite direction.

The speed of the current in a river is 6 mph. A ferry operator who works that part of the river is looking to
Morgarella [4.7K]

Answer:

  • 9 mph

Step-by-step explanation:

Let he speed of the boat on the lake is x.

<u>Considering the speed of the current it will take him:</u>

  • 22.5/(x + 6) + 22.5/(x - 6) = 9
  • 2.5 / (x  + 6) + 2.5 / (x - 6) = 1
  • 2.5(x - 6 + x + 6) = (x + 6)(x - 6)
  • 2.5*2x = x² - 36
  • x² - 5x - 36 = 0
  • x = (5 ± √(5² + 4*36))/2 = (5 ± 13) / 2
  • x = (5 + 13)/2 = 9 mph (negative root is discarded as the speed should be positive)
