not enough information
To determine the fraction of the total apples picked that were sold as fresh fruit, we first need to find the fraction of apples remaining after discarding 1/10 of them. Let's call this fraction A.
A = 1 - 1/10 = 9/10
Then, we can find the fraction of the remaining apples that were sold as fresh fruit by subtracting the fraction that was made into cider (300 apples) from 9/10.
Fresh fruit fraction = 9/10 - 300/whole quantity
Since we don't have information about the total quantity of apples picked, we cannot determine the exact fraction of apples sold as fresh fruit. Therefore, the answer is "not enough information."

To find the total area of the town of Oak Manor, we can multiply the length and width:
Total area = Length × Width = 3.8 miles × 4.2 miles
Total area = 15.96 mi^2
Therefore, the total area of Oak Manor is 15.96 mi^2.
A diver searches for a sunken treasure that is 97.2 feet below the surface. What is the diver's elevation when he is 2/3 of the way down? (1 point)

negative 64 point 8 ft.
−32.4 ft.
To find the diver's elevation when he is 2/3 of the way down, we can multiply the depth of the treasure (97.2 feet) by 2/3.
Elevation = 97.2 feet × 2/3 = 64.8 feet
However, since the treasure is below the surface, the elevation will be negative. Therefore, the correct answer is:
−64.8 ft. (negative 64.8 feet)

To find the height of the basketball player's son, we need to multiply the height of the player (6 2/3 feet) by 1/4.
Height of son = 6 2/3 ft × 1/4
Converting the mixed number to an improper fraction:
Height of son = (20/3) ft × 1/4
Multiplying the fractions:
Height of son = 20/12 ft
Simplifying the fraction:
Height of son = 5/3 ft
Converting the improper fraction back to a mixed number:
Height of son = 1 2/3 ft
Therefore, the son is 1 2/3 feet tall.
