Answer:
Percent decrease in the mass of the pumpkin is 40% .
Step-by-step explanation:
Formula
[tex]Percentage = \frac{Change\ in\ value\times 100}{Initial\ value}[/tex]
Where change in value = |Final value - Initial value|
As given
Finley’s pumpkin had a mass of 6.5 kilograms (kg) before he carved it.
After carving it, the pumpkin had a mass of 3.9 kg.
Final value = 3.9 kg
Initial value = 6.5 kg
Where
Change in value = |3.9 - 6.5|
Change in value = |-2.6|
= 2.6
Putting all the values in the formula
[tex]Percentage = \frac{2.6\times 100}{6.5}[/tex]
[tex]Percentage = \frac{2600\times 10}{65\times 10}[/tex]
[tex]Percentage = \frac{2600}{65}[/tex]
= 40%
Therefore percent decrease in the mass of the pumpkin is 40% .
