Question 3 of 5

How many ounces are in a gallon?

Correct Answer: B

Rationale: The correct answer is B: 128 oz. There are 128 ounces in a gallon because a gallon is a unit of volume used in the US customary system and is equivalent to 128 fluid ounces. This conversion factor is widely recognized and used in various applications. The other choices are incorrect because they do not accurately represent the conversion between gallons and ounces. Choice A (120 oz) is close but not the exact conversion. Choices C (100 oz) and D (105 oz) are significantly lower than the actual conversion of 128 oz in a gallon.

Question 4 of 5

A farmer wants to plant trees around the outside boundaries of his rectangular field with dimensions of 650 meters 780 meters. Each tree requires 5 meters of free space all around it from the stem. How many trees can he plant?

Correct Answer: C

Rationale: To calculate the number of trees, we need to determine the area available for planting trees after considering the space each tree requires. The total area of the rectangular field is 650m * 780m = 507,000 sq. meters. Each tree requires a space of (5+5) meters horizontally and (5+5) meters vertically around it, totaling 10m * 10m = 100 sq. meters per tree. Therefore, the area needed for each tree is 100 sq. meters. To find the number of trees that can be planted, we divide the total area of the field by the area needed for each tree: 507,000 sq. meters / 100 sq. meters per tree = 5070 trees. However, since the space around the boundary cannot accommodate a full tree, we have to deduct the trees that cannot be planted along the boundary. The number of trees that cannot be planted along the length of the field = 780m /

Question 5 of 5

How many inches are in 2 yards?

Correct Answer: D

Rationale: To convert yards to inches, we need to know that 1 yard is equal to 36 inches. So, to find out how many inches are in 2 yards, we multiply 2 by 36, which equals 72 inches. Therefore, the correct answer is D. Choice A (36 inches) is the equivalent of 1 yard, not 2 yards. Choice B (48 inches) and C (60 inches) are incorrect conversions of 2 yards to inches.
