Answer:
Step-by-step explanation:
Given:
1 inch corresponds to 4 feet
4 and 1/4 inches = ?
We can determine the value for 4 and 1/4 inch line on the blueprint by using ratio. We let x be the value in feet:
![\frac{x}{4(1)/(4)\text{ inches}}=\frac{4\text{ f}eet}{1\text{ inch}}](https://img.qammunity.org/2023/formulas/mathematics/college/nvxyrofs5ia1w2z3thrlnns8wqqy6fgehd.png)
Simplify and rearrange
![\begin{gathered} \frac{x}{4(1)/(4)\text{ inches}}=\frac{4\text{ f}eet}{1\text{ inch}} \\ (x)/((17)/(4))=(4)/(1) \\ x=(4((17)/(4)))/(1) \\ x=(17)/(1) \\ x=17\text{ f}eet \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/kkqjjr6bn0ft7lvpsbmg9z8quo9jg6p6va.png)
Therefore, 4 and 1/4 inch line corresponds to 17 feet.
