How many feet did the tree grow between years 3 and 4?
Understand the Problem
The question asks for the growth of a tree between years 3 and 4 based on the provided graph, which indicates the tree's height at different years.
Answer
The tree grew $2 \text{ feet}$ between years 3 and 4.
Answer for screen readers
The tree grew $2 \text{ feet}$ between years 3 and 4.
Steps to Solve
- Identify Heights at Years 3 and 4
From the graph, find the tree's height at Year 3 and Year 4. The height at Year 3 is 7 feet, and at Year 4, it is 9 feet.
- Calculate the Growth
To determine how much the tree grew between these two years, subtract the height at Year 3 from the height at Year 4:
$$ \text{Growth} = \text{Height at Year 4} - \text{Height at Year 3} $$
Substituting the values:
$$ \text{Growth} = 9 \text{ ft} - 7 \text{ ft} $$
- Compute the Result
Perform the subtraction:
$$ \text{Growth} = 2 \text{ ft} $$
The tree grew $2 \text{ feet}$ between years 3 and 4.
More Information
The growth of trees can vary significantly from year to year due to several factors such as climate conditions, soil quality, and species type. In this case, the increase of 2 feet between years 3 and 4 indicates a healthy growth rate for this tree.
Tips
- Misreading the heights from the graph. Always double-check the values on the vertical axis.
- Forgetting to subtract the heights in the correct order; it’s important to take the later year (Year 4) minus the earlier year (Year 3).
