A ceiling is made up of tiles. Every square meter of the ceiling requires 10.75 tiles. Fill in the table with the missing values.

On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in miles, \(d\), to the number of hours flying, \(t\), is \(t = \frac{1}{500} d\). How long will it take the airplane to travel 800 miles?

Each table represents a proportional relationship. For each, find the constant of proportionality, and write an equation that represents the relationship.

A map of Colorado says that the scale is 1 inch to 20 miles or 1 to 1,267,200. Are these two ways of reporting the scale the same? Explain your reasoning.

Here is a polygon on a grid.

A polygon aligned to a square grid. The polygon is made up of two shapes, joined together on an edge. To the left is a square that has side lengths of 2 units. On the right of the square, is an isosceles triangle with its 2 unit length base joined to the edge of the square. The vertex of the triangle is 2 units to the right.  

1. Draw a scaled copy of the polygon using a scale factor 3. Label the copy A.

2. Draw a scaled copy of the polygon with a scale factor \(\frac{1}{2}\). Label it B.

3. Is Polygon A a scaled copy of Polygon B? If so, what is the scale factor that takes B to A?
