Answer 1

Given:

Each story is 13ft tall.

Step-by-step explanation:

a) To find: The height of the skyscraper if it has 55 stories.

Since the number of stories increases the height of the skyscraper also increases.

That is,

`\begin{gathered} h=Number\text{ of stories}* Height\text{ of each story} \\ h=55*13 \\ =715ft \end{gathered}`

b) To find: The height of the skyscraper if it has 65 stories.

The height of the skyscraper would be,

`\begin{gathered} h=Number\text{ of stories}* Height\text{ of each story} \\ h=65*13 \\ =845ft \end{gathered}`

c) To find: The height of the skyscraper if it has 75 stories.

The height of the skyscraper would be,

`\begin{gathered} h=Number\text{ of stories}* Height\text{ of each story} \\ h=75*13 \\ =975ft \end{gathered}`

d) To find: The equation of the height if it has f stories

The height of the skyscraper would be,

`\begin{gathered} h=Number\text{ of stories}* Height\text{ of each story} \\ h=f*13 \\ h=13f \end{gathered}`

Final answer:

a) The height of the skyscraper if it has 55 stories is 715ft.

b) The height of the skyscraper if it has 65 stories is 845ft.

c) The height of the skyscraper if it has 75 stories is 975ft.

d) The expression that represents the height of f stories is h = 13f.
