Question

Can someone help me with my practice today. I need help with this question.

Answer 1

There can be at most 28 lines that can be typed on a page

Step-by-step explanation:

Given that:

• One line uses about 5/14 inch

,

• There are 0.5 inch margins at the top and bottom of a page

,

• The page is 11 inches long.

We want to know lines that can be typed on a page.

Let the number of lines that can be typed in a page be represented by x.

Then the addition of the number of lines that can be typed on a page, and the margins at the top and bottom, is at least 11.

This can be written as:

`(5)/(14)x+2(0.5)\leq11`

Solving the inequality above, we have:

`\begin{gathered} (5)/(14)x+1\leq11 \\ \\ \text{Substract 1 from both sides} \\ (5)/(14)x\leq10 \\ \\ \text{Multiply both sides by 14/5} \\ x\leq10*(14)/(5) \\ \\ x\leq(140)/(5)=28 \end{gathered}`

There can be at most 28 lines that can be typed on a page.
