Answer:

Air pressure = 4.6\frac{\text{lb}}{\text{in}^{2} }

Step-by-step explanation:

Relationship between air pressure and altitude can be modeled by,

P = 14.7e14.7e^{-0.00004h}

Where P = Air pressure

and h = altitude above the sea level

Air pressure on Mount Everest having altitude = 29028 feet abve the sea level will be,

P = 14.7e^{-0.00004\times 29028}

  = 14.7\times e^{-1.16112}

  = 4.603

  ≈ 4.6 \frac{\text{lb}}{\text{in}^{2} }

Therefore, air pressure on Mount Everest = 4.6 \frac{\text{lb}}{\text{in}^{2} }

If RS = 17, ST = x + 6, and RT = 3x - 5, What is ST.
tigry1 [53]

Answer:

ST = 20

Step-by-step explanation:

Line segment RS and segment ST must add up to line segment RT

Step 1: Define

RS = 17

ST = x + 6

RT = 3x - 5

Step 2: Set up equation

mRS + mST = mRT

17 + x + 6 = 3x - 5

Step 3: Solve for <em>x</em>

x + 23 = 3x - 5

23 = 2x - 5

28 = 2x

x = 14

Step 3: Find mST

ST = x + 6

ST = 14 + 6

ST = 20
