They are similar!

21 ÷ 15 = 1.4

5 x 1.4 = 7
8 x 1.4 = 11.2

Since the scale factor for the enlargement of all of the sides is the same, the triangles are mathematically similar!

Lady bird [3.3K]

3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.

Step-by-step explanation:

<u>DATA:</u>

Length of strips Eli need is 2.5 feet long

Length of roll of ribbon is 7.5 feet long

Number of strips that can be cut from the 7.5 feet long roll is x

<u>SOLUTION:</u>

To determine how many strips can be cut, divide total length of roll of ribbon by the length of strips needed.

Number of strips that can be cut = \frac{Total Length of roll}{Length of strips needed}

x = \frac{7.5}{2.5}  (expression)

x = 3 strips

Therefore, 3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.
