Formula

2*(L + W) = L * W

Given

W = 3

Solution

2*(L + 3) = 3*L

2L+ 6 = 3L                      Subtract 2L from both sides

2L - 2L + 6 = 3L - 2L      combine

6 = L

Answer: The length is 6 units long.

If I toss a fair coin in real life and I get two heads in a row, does that change the probability of getting one tail in every t
stepladder [879]
Getting two heads in a row does not change the probability of getting a tail. There is a 50/50 chance for both heads and tails each time you flip a coin, because there are two possibilities each equally possible. The 50% probability of getting a tails is not a guarantee. It's possible to get more heads than tails, or vice versa. What the probability means is that on average the results are about equal, and you have an equal likelihood of getting either result. 

Mythbusters has an episode on this, actually. They explain it really well. I recommend you watch it.

Two airplanes are flying in the air at the same height: airplane A is flying east at 250 mi/h and airplane B is flying north at
just olya [345]

Answer:

  decreasing at 390 miles per hour

Step-by-step explanation:

Airplane A's distance in miles to the airport can be written as ...

  a = 30 -250t . . . . . where t is in hours

Likewise, airplane B's distance to the airport can be written as ...

  b = 40 -300t

The distance (d) between the airplanes can be found using the Pythagorean theorem:

  d^2 = a^2 + b^2

Differentiating with respect to time, we have ...

  2d·d' = 2a·a' +2b·b'

  d' = (a·a' +b·b')/d

__

To find a numerical value of this, we need to find the values of its variables at t=0.

  a = 30 -250·0 = 30

  a' = -250

  b = 40 -300·0 = 40

  b' = -300

  d = √(a²+b²) = √(900+1600) = 50

Then ...

  d' = (30(-250) +40(-300))/50 = -19500/50 = -390

The distance between the airplanes is decreasing at 390 miles per hour.
