1 revolution is 360 degrees

 1 hour = 60 minutes

360/60 = 6

 so it rotates 6 degrees every minute

135/6 = 22.5 minutes

Answer:

22.5 minutes.

Step-by-step explanation:

Let x represent time spent by visitor at the tower.

We have been given that the Skylon tower in Niagara Falls Canada has a revolving restaurant 775 feet above the falls. The restaurant makes a complete revolution once every hour.

We know that 1 hour equals 60 minutes.

We also know that 1 full revolution equals 360 degrees.

Now, we will use proportions to solve our given problem as:

\frac{\text{Time}}{\text{Rotation}}=\frac{60\text{ min}}{360^{\circ}}

\frac{x}{135^{\circ}}=\frac{60\text{ min}}{360^{\circ}}

\frac{x}{135^{\circ}}*135^{\circ}=\frac{60\text{ min}}{360^{\circ}}*135^{\circ}

x=\frac{1\text{ min}}{6}*135

x=22.5\text{ min}

Therefore, the visitor spent 22.5 minutes at the tower.

What is the slope of the line?
spin [16.1K]

Answer:

-7/2

Step-by-step explanation:

The slope of a line can be defined as: \frac{rise}{run}, which can be more formally calculated as: \frac{y_2-y_1}{x_2-x_1}, where it's essentially the same thing, except the rise/run is being calculated with two points (which you already need)

So let's just say: (x_1, y_1)=(-5, 5)\text{ and } (x_2, y_2)=(-3, -2)

Plugging the values into the equation we get: \frac{-2-5}{-3-(-5)}\implies\frac{-7}{-3+5}\implies-\frac{7}{2}

You can also just look at the graph and see that from point 1 to point 2, it "rised" -7 units, and "ran" 2 units.

Notice how the "rise" is negative? That just means it went down.
