Sara discarded 1\10 of the apples she picked as defective. Of the apples remaining, 300 were made into cider. The rest were sold as fresh fruit. What fraction of the total apples picked were sold as fresh fruit?(1 point)

4\5
To find the fraction of the total apples picked that were sold as fresh fruit, we need to know the total number of apples picked before any were discarded. Unfortunately, the total number of apples picked is not provided in the information given. Therefore, the correct response is "not enough information."

To find the total area of a rectangle, we multiply its length by its width. In this case, the length is given as 3.8 miles and the width is given as 4.2 miles.
Area = Length x Width
Area = 3.8 miles x 4.2 miles
Area = 15.96 square miles
Therefore, the total area is 15.96 square miles.

To find the diver's elevation when he is 2/3 of the way down, we need to calculate 2/3 of the total depth.
2/3 of 97.2 feet = (2/3) x 97.2 = 64.8 feet
Therefore, the diver's elevation when he is 2/3 of the way down is -64.8 ft.

To calculate the height of the basketball player's son, we need to find 1/14 of the player's height.
1/14 of 623 feet = (1/14) x 623 = 44.5 feet
Therefore, the son is 44.5 feet tall.
