Answer:
The tree grew 0.65 feet.
Step-by-step explanation:
We have,
Height of tree when planted = [tex]4\frac{3}{4}[/tex] = [tex]\frac{19}{4}[/tex]
Height of tree one year later = [tex]5\frac{2}{5}[/tex] = [tex]\frac{27}{5}[/tex]
So, we get that the difference in the height of the tree in a year is,
Difference = [tex]\frac{27}{5}-\frac{19}{4}[/tex]
i.e. Difference = [tex]\frac{27\times 4-19\times 5}{20}[/tex]
i.e. Difference = [tex]\frac{108-95}{20}[/tex]
i.e. Difference = [tex]\frac{13}{20}[/tex] = 0.65 feet
Hence, the tree grew 0.65 feet.
