Sara discarded 110 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)
To determine the fraction of the total apples picked that were sold as fresh fruit, we need to know the total number of apples picked. However, the information provided in the question only mentions the number of apples discarded and the number of apples made into cider.
Without the total number of apples picked, we cannot calculate the fraction of apples that were sold as fresh fruit.

To find the total area, you need to multiply the length by the width. So, for Oak Manor, the total area would be 3.8 miles * 4.2 miles = 15.96 mi². Therefore, the correct response is 15.96 mi² (or 15.96 square miles).

To find the diver's elevation when he is 23% of the way down, we need to calculate 23% of 97.2 feet.
23% of 97.2 feet = 0.23 * 97.2 feet = 22.356 feet
Since the diver is descending, the elevation would be negative. Therefore, the correct response is -22.356 ft. However, none of the provided responses match this exact value.
nope wrong
Apologies for the incorrect response. Let's recalculate.
To find the diver's elevation when he is 23% of the way down, we can multiply 97.2 feet by 0.23:
97.2 feet * 0.23 = 22.356 feet
Since the diver is descending, the elevation would be negative. Therefore, the correct response is -22.356 ft.

To find the diver's elevation when he is two-thirds (2/3) of the way down, we need to calculate 2/3 of 97.2 feet.
2/3 * 97.2 feet = 64.8 feet
Since the diver is descending, the elevation would be negative. Therefore, the correct response is -64.8 ft.
A basketball player is 623 feet tall. His infant son is 14 as tall. How tall is his son?(1 point)
Responses
123 ft.
2212 ft.
223 ft.
112 ft.
If the basketball player is 623 feet tall and his infant son is 14 times as tall, we need to calculate 14 times the height of the basketball player.
Height of the son = 14 * 623 feet = 8712 feet
Therefore, the correct response is 8712 ft.
A basketball player is 6 2/3 feet tall. His infant son is 1/4 as tall. How tall is his son?(1 point)
Responses
1 2/3 ft.
2 2/12 ft.
2 2/3 ft.
1 1/2 ft.
To find the height of the son, we need to calculate 1/4 of the basketball player's height.
Height of the son = (1/4) * (6 2/3) = (1/4) * (20/3) = (20/12) * (1/4) = 20/48 = 5/12
Therefore, the correct response is 5/12 ft, which is equivalent to 1 2/5 ft or 1.67 ft. However, none of the provided responses matches this exact value.
nope
Apologies for the mistake. Let's recalculate it correctly.
To find the height of the son, we need to calculate 1/4 of the basketball player's height.
Height of the son = (1/4) * (6 2/3) = (1/4) * (20/3) = 20/12 * 1/4 = 20/48 = 5/12
Therefore, the correct response is 5/12 ft, which is equivalent to 1 7/12 ft or 1.42 ft.
The correct response is 1 2/3 ft.
