A pilot can travel 540 miles with the wind in the same amount of time as 380 miles against the wind. Find the speed of the wind
stepladder [879]
T=d/v

540/(230+w)=380/(230-w)

540(230-w)=380(230+w)

124200-540w=87400+380w

124200-920w=87400

-920w=-36800

w=40

So the wind speed is 40 miles per hour.

Figure T is similar to figure W which answer is closest to the length of side XY
beks73 [17]
As they are similar triangles, one is simply going to be bigger than the other, meaning that if triangle T’s side QS is = 9 and triangle W’s corresponding side ZX is =6.5. When dividing 9 by 6.5, it is obvious that triangle W is 0.72 smaller than triangle T. All you then have to do to calculate length of side XY is times side QR on triangle T -cause it’s the corresponding side of these two triangles- by 0.72, and you’ll have your answer of XY= 8.125 :)

Need help with all And have to show work
kari74 [83]
Altho' I can easily guess what you're supposed to do here, I must point out that you haven't included the instructions for this problem.

I'll help you by example.  Let's look at the first problem:

"Evaluate  6(z-1) at z-4."

Due to "order of operations" rules, we must do the work inside the parentheses FIRST.  Replace the z inside (z-1) with "-4".  We obtain

6(-4-1) = 6(-5) = -30 (answer.)

Your turn.  Try the next one.  If it's unclear, as questions.
