Answer:

  21 miles per hour

Step-by-step explanation:

Let w represent the wind speed. Then the travel time is ...

  400/(329 +w) = 352/(329 -w)

  400(329 -w) = 352(329 +w)

  (352+400)w = 329(400 -352)

  w = (400 -352)/(400 +352)·329 = 48/752·329 = 21

The wind speed is 21 miles per hour.

liubo4ka [24]

Answer:

Midpoint for A is (1,5) and for B it is (2.5,4.5)

Step-by-step explanation:

To get the midpoint you add the x coordinates and divide by 2 and then the y coordinates and divide by 2.

X = (3 + -1)/2    y = (8+ 2)/2

   =2/2 = 1             10/2=5

What is the error in this problem
dlinn [17]

Answer:

10). m∠x = 47°

11). x = 30.96

Step-by-step explanation:

10). By applying Sine rule in the given triangle DEF,

   \frac{\text{SinF}}{\text{DE}}=\frac{\text{SinD}}{\text{EF}}

   \frac{\text{Sinx}}{7}=\frac{\text{Sin110}}{9}

   Sin(x) = \frac{7\times (\text{Sin110})}{9}

   Sin(x) = 0.7309

   m∠x = \text{Sin}^{-1}(0.7309)

   m∠x = 46.96°

   m∠x ≈ 47°

11). By applying Sine rule in ΔRST,

   \frac{\text{SinR}}{\text{ST}}=\frac{\text{SinT}}{\text{RS}}

   \frac{\text{Sin120}}{35}=\frac{\text{Sin50}}{x}

   x = \frac{35\times (\text{Sin50})}{\text{Sin120}}

   x = 30.96
