Answer:
inches
Explanation:
Height of the tallest conifer =
inches
Height of the shortest conifer = 6 + measure of one segment on the number line
Measure of one segment on the number line =
![(6(1)/(2)-6)/(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/rxpzcdgqdjyau2ga4nu8k2tp45f71j5i80.png)
=
![((1)/(2))/(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/587vkxao9dy5u5pehj3bj8rgrdlr3cbk2i.png)
=
![(1)/(4)](https://img.qammunity.org/2022/formulas/mathematics/college/8sgkbqu3iaqhrj3ec3ravgp4pqwnwrhmb4.png)
Therefore, height of the shortest conifer = 6 +
![(1)/(4)](https://img.qammunity.org/2022/formulas/mathematics/college/8sgkbqu3iaqhrj3ec3ravgp4pqwnwrhmb4.png)
=
![6(1)/(4)](https://img.qammunity.org/2022/formulas/mathematics/high-school/4sc8bt44wirlhkh8rgv312v3vewhz7dl0j.png)
Difference in tallest and shortest conifer =
![9(1)/(2)- 6(1)/(4)](https://img.qammunity.org/2022/formulas/mathematics/high-school/r2xcmh5nko8x8g1pknngye3mv4s5mbmlvr.png)
= (9 - 6) +
![((1)/(2)- (1)/(4))](https://img.qammunity.org/2022/formulas/mathematics/high-school/8wplcgkdx138ze5csl9z3452ck9hzzlxax.png)
= 3 +
![(1)/(4)](https://img.qammunity.org/2022/formulas/mathematics/college/8sgkbqu3iaqhrj3ec3ravgp4pqwnwrhmb4.png)
=
inches
