vladimir2022 [97]

Answer:

T(100) represents that the plane flies against the wind at 110mph for 0.714 hours

Step-by-step explanation:

Given

$w = headwind$

$T = time$

Model:

 $T(w) = \frac{300}{530 - W}$  -- This was not properly presented in your question

Required

What does T(110) means

First, we calculate T(110):

Substitute 110 for w in $T(w) = \frac{300}{530 - W}$

The expression becomes

$T(110) = \frac{300}{530 - 110}$

$T(110) = \frac{300}{420}$

$T(110) = 0.714$ -- approximated

T(100) represents that the plane flies against the wind at 110mph for 0.714 hours

Answer:

x = 9

TH = 12

Step-by-step explanation:

since TM is half of HM, the equation is:

2(21 - x) = 3x - 3

42 - 2x = 3x - 3

45 = 5x

x = 9

TH = 21 - x

TH = 21 - 9

TH = 12
