the angle of elevation from the bottom of a scenic gondola ride to the top of a mountain is 31 degrees. if the vertical distance
Eduardwww [97]

Answer:

The ride lasts 10 minutes.

Step-by-step explanation:

The triangle that is formed is attached.

In order to find out how long the ride lasts, we need to figure out the horizontal distance d.

From trigonometry we have:

tan(31^o)=\frac{902}{d}.

Therefore

d=\frac{902\:feet}{tan(31^o)}=1501\:feet.

Now the amount of time t the gondola ride lasts is equal to the distance d divided by the speed of the gondola:

t=\frac{1501ft}{155ft/sec} =\boxed{9.69\:minutes.}

To the nearest minute this is 10 minutes.

Answer:

x=9/2

Step-by-step explanation:

2(x−2)+10=6x−12

Step 1: Simplify both sides of the equation.

2(x−2)+10=6x−12

(2)(x)+(2)(−2)+10=6x+−12(Distribute)

2x+−4+10=6x+−12

(2x)+(−4+10)=6x−12(Combine Like Terms)

2x+6=6x−12

2x+6=6x−12

Step 2: Subtract 6x from both sides.

2x+6−6x=6x−12−6x

−4x+6=−12

Step 3: Subtract 6 from both sides.

−4x+6−6=−12−6

−4x=−18

Step 4: Divide both sides by -4.

−4x−4=−18−4

x=9/2

Hope this helps :)
