Answer:

  • 186.55 mph

Step-by-step explanation:

Let the speed of the plane be s

<u>The speed of the plane in the same direction is</u>

  • s + 12

<u>The speed of the plane against wind is</u>

  • s - 12

<u>Time = distance/speed</u>

  • 455/(s + 12) = 400/(s - 12)

<u>Solving for s</u>

  • 400(s + 12) = 455(s - 12)
  • 400s + 400*12 = 455s - 455*12
  • 455s - 400s = (400 + 455)*12
  • 55s = 10260
  • s = 10260/55
  • s = 186.55 mph

if a plane flies 455 miles with wind, and takes 400 against the wind, and the wind is blowing at a speed of 12mph, then the plane can fly 2455 miles if it's still in the air

10 = 2/3m - 3/2m
2/3m - 3/2m = 10
m ( 2/3 - 3/2 ) = 10
-5/6m = 10
5m = -60
m = -12

Uhhhhhhh i dont understand tis
ra1l [238]

Answers:

  1. f) hard working. Think of "industry" or "industrial" to help remember.
  2. b) state of disorder. Mayhem is effectively chaos.
  3. e) expressions of sorrow. For example, you would give lamentations at a funeral.
  4. i) gridlock or standstill. Example: "Congress is at an impasse on passing a new spending bill". You can think of it like saying "it's not possible to pass or get through".
  5. a) A long angry rant or speech. I'm not sure what trick you can use to remember this, but the term "harangue" sounds negative which seems to be fitting with the angry rant/speech.
  6. c) Overly concerned about small details. Usually you might hear it used in a way where someone mentions "not to be pedantic", they basically mean "not to nitpick at the fine details".
  7. h) Terrible; extremely poor. Someone who is abominable has bad morals or values as a person. For instance, a murderer is someone who is abominable.
  8. d) Characterized as having too high of an opinion of oneself. Someone with a big ego only thinks about themself and no one else. The tern narcissism also applies.
  9. g) The effects of something. Specifically, repercussions are referred to as unintended consequences of an action.
  10. j) The act of surrendering. I don't know of a useful trick to help remember this term.
