The manufacturer of an energy drink spends $1.20 to make each drink and sells them for $2. The manufacturer also has fixed costs

Nadya [2.5K]

Revenue is money made in total. It doesn’t matter how much profit, so the manufacturing cost doesn’t matter.

Bob is driving along a straight and level road toward a mountain. At some point on his trip, he measures the angle of elevation

DerKrebs [107]

Answer:

Option A.

Step-by-step explanation:

Distance between Bob and the center of the mountain at the base = 19,427.5 ft.

Angle of elevation to the top of the mountain = 25°11'

We know that

1 degree = 60 minutes

1/60 degree = 1 minute

$25^{\circ}11'=25^{\circ}+\frac{11}{60}{\circ}\Rightarrow 25^{\circ}+0.183^{\circ}=25.183^{\circ}$

Let the height of the mountain be h.

In a right angled triangle

$\tan\theta = \frac{opposite}{adjacent}$

$\tan(25.183^{\circ}) = \frac{h}{19427.5}$

$\tan(25.183^{\circ})\times 19427.5 = h$

$h=0.4702\times 19427.5$

$h=9134.8105$

$h\approx 9135$

Therefore, the height of the mountain to the nearest foot 9135. Option A is correct.
