2 * plane speed in still air = 289mph + 257mph = 546
plane speed in still air = 273 mph

plane speed in still air + wind speed = 289
273 + wind speed = 289
Therefore, wind speed = 16 mph

Why does the multiplicative inverse of a number have the same sign as the number?
denis23 [38]
<span>Look at the definition of multiplicative inverse. If two numbers are multiplicative inverses of each other, then by definition, their product will be equal to 1. And 1 is a positive number. If both numbers being multiplied are positive, then the result is positive. And of both numbers being multiplied are negative, then the result is still positive. But if one number is positive and the other is negative, then the result is negative. So if you want a positive result, then both numbers you're multiplying have to have the same sign. And since we want a result of 1 for multiplicative inverses and since 1 is positive, then the numbers being multiplied have to have the same sign.</span>

One serving of granola provides 4% of the protein you need daily. You must get the remaining 48 grams from other sources. How ma
Anna35 [415]
You will need 46.08 grams.

48 • 0.04 (4%) = 1.92
multiply 48 by 0.04 to find what 4% of 48g is
48 - 1.92 = 46.08
then subtract the 4% to get the rest amount

Two angles of a triangle have the same measure and the third one is 18 degrees greater than the measure of each of the other two
kvv77 [185]

Answer:

72°

Step-by-step explanation:

Let the 2 equal angles be x then the third angle is x + 18

The sum of the 3 angles in a triangle = 180°, thus

x + x + x + 18 = 180, that is

3x + 18 = 180 ( subtract 18 from both sides )

3x = 162 ( divide both sides by 3 )

x = 54

Hence

the largest angle = x + 18 = 54 + 18 = 72°

X-Y-2Z =-11<br> X-2Y-Z = -11 <br> -X+Y+3Z = 14
Snowcat [4.5K]

Answer:

  (X, Y, Z) = (-2, 3, 3)

Step-by-step explanation:

We can subtract the second equation from the first to get ...

  Y -Z = 0

We can add the third equation to the first to get ...

  Z = 3

Then ...

  Y -3 = 0   ⇒   Y = 3

and ...

  X -3 -2(3) = -11

  X = -2 . . . . . . . . . add 9

The solution is ...

  (X, Y, Z) = (-2, 3, 3)
