Explanation:
When the diver swims to -10 feet, they are 10 feet below the top of the water (which is at 0 feet altitude). At the same time, the captain of the boat remains at an altitude of 15 feet above the top of the water. Therefore, the diver will not be at the same distance below the top of the water as the captain is above it.
Explanation:
Option C is correct, since 27.5% of students are born in April, and only 15% are born in July.
Explanation:
To find the length of each shelf, divide the total length of wood (25 feet) by the number of shelves (9).
25 feet/9 shelves ≈ 2.78 feet
So, each shelf measures approximately 2.78 feet.
Therefore, the correct answer is 2 and 3 feet.
Explanation:
Statement 2 is true about the principal’s conclusion.
Explanation:
Let's find the scale for Map 2.
For Map 1, 1 inch = 3/4 mile.
Given that Map 2 has dimensions half of Map 1, its scale will be doubled.
So, for Map 2, 1 inch = 3/4 × 2 = 3/2 miles.
Therefore, the correct answer is: 3/4 mile to 1/2 inch.
Explanation:
To find the percentage of students who scored above 80%, divide the number of students who scored above 80% by the total number of students and multiply by 100: (18/30) * 100 = 60%.
Explanation:
60:96 is an equivalent ratio of blue tiles to green tiles.
Explanation:
The perimeter of a rectangle is the sum of all its sides. For this pool, the perimeter would be 2 * (length + width) = 2 * (20 + 10) = 2 * 30 = 60 meters.
Explanation:
Divide the total number of students by the sum of the ratio parts (3 + 2) to find the value of each part. Then, multiply the number of parts representing boys (3) by this value: (3/5) * 25 = 15. So, there are 15 boys in the class.
Explanation:
The statement is False because the distance from the captain to the diver is the same as the distance from the top of the water to the ocean floor, both being 20 feet.
Explanation:
True. Since the diver is at -5 feet and the captain is at 15 feet, the vertical distance between them is 20 feet. This is the same as the depth of the ocean floor, which is also 20 feet below the surface. Therefore, the distance from the captain to the top of the water is the same as the distance from the diver to the ocean floor.
