If one number is 20 (a multiple of 5), the other number would be 10, making it a valid option.

5 and 25 add up to 30, and 25 is a multiple of 5.

5 and 25 add up to 30, and 5 is a multiple of 5.

12 is a multiple of 6, and 12 + 18 = 30.

Both numbers can be expressed as 6k + 4. Their sum is 12k + 8, which gives a remainder of 2 when divided by 6.

For the sum to be a multiple of 10, at least one of the numbers must be even.

The surface area of a cube is given by the formula SA = 6a². Setting 6a² = 216, we find a² = 36, thus a = 6 meters.

The surface area of a cylinder is given by SA = 2πr(h + r). Setting 150π = 2πr(10 + r), we find r = 5 cm.

The surface area of a cylinder is given by SA = 2πr(h + r). Setting 150π = 2πr(5 + r), we find r = 4 cm.

The second equation is a multiple of the first, indicating that both equations represent the same line.

The reciprocals are 1, 4, and 9. The common difference is 4 - 1 = 3.

The reciprocals of the terms are 1/3, 1/6, and 1/x. Since they form an arithmetic progression, we can set up the equation: 1/6 - 1/3 = 1/x - 1/6, solving gives x = 12.

The reciprocals are 1/4, 1/2, and 1/x. The common difference is 1/2 - 1/4 = 1/4, so 1/x = 1/2 + 1/4 = 3/4, thus x = 4/3.

Product B represented 40% of total sales in Q4, selling 600 units.

The average sales per quarter for Product A is 1200 / 4 = 300 units.

30% of 5000 units is 1500 units sold for apples.

Apples represent 1500 out of 5000 units, which is 30% of total sales.

Product A shows a consistent upward trend, indicating a significant increase by Q4.

Product A shows a consistent upward trend, indicating a likely increase in sales by Q4.

The complement of A in U is the set of elements in U that are not in A, which is {1, 3, 5, 7, 9, 10}.

The complement of set A consists of elements in the universal set U that are not in set A. Therefore, the complement is {1, 3, 5}.

Using the principle of inclusion-exclusion, the number of elements in either A or B is: (A + B - Both) = 40 + 30 - 10 = 60. Therefore, elements in neither = U - (A ∪ B) = 100 - 60 = 40.

In reverse alphabetical order, 'date' comes first.

In alphabetical order, 'bat' comes before 'cat', making it the second word.

The correct arrangement that forms a coherent sentence is 'The quick brown fox'.

Let the two angles be x and x - 10. Since they are complementary, x + (x - 10) = 90. Solving gives x = 50 degrees, and the other angle is 40 degrees.

Let the angles be x and x - 10. Then, x + (x - 10) = 90. Solving gives x = 50 degrees and the other angle is 40 degrees.

Let the smaller angle be x. Then the larger angle is x + 10. Since they are complementary, x + (x + 10) = 90. Solving gives x = 40 degrees, so the angles are 40 and 50 degrees.

Let the smaller angle be x. Then the larger angle is 2x. The equation x + 2x = 90 gives x = 30 degrees and 2x = 60 degrees.

Complementary angles add up to 90 degrees. Therefore, the other angle is 90 - 25 = 65 degrees.
