Answer:
The heights of the two trees each year for five years = 32 and 37.5.

Explanation:
In the above-given question,
given that,
Bur oak and hickory trees are deciduous, which means that they lose their leaves seasonally.
A bur oak is 25\(\frac{1}{2}\) feet tall and grows 1\(\frac{1}{2}\) feet each year.
A hickory is 30 feet tall and grows 1\(\frac{1}{2}\) feet each year.
25(1/2) = 51/2 = 25.5.
3/2 = 1.5.
25.5 + 1.5 = 27.0.
27.0 + 1.5 = 28.5.
28.5 + 1.5 = 30.
30 + 1.5 = 31.5.
31.5 + 1.5 = 32.
30 + 1.5 = 31.5.
31.5 + 1.5 = 33.
33 + 1.5 = 34.5.
34.5 + 1.5 = 36.0.
36.0 + 1.5 = 37.5.

Question 9.
If each tree continues to grow 1\(\frac{1}{2}\) feet each year, how tall will each tree be after 15 years?

30 × 4 = 120
60 × 4 = 240
90 × 4 = 360
120 × 4 = 480
150 × 4 = 600
So, the total number of miles biked is always 4 times the total number of miles run.

Convince Me! Generalize Do you think the relationship between the corresponding terms in the table Jack created will always be true? Explain.
