Question

12.5
17.9
20.0
23.3

Answer 1

17.9.

Explanation:

To approximate 15 plus the cube root of 25 to the nearest tenth, we need to calculate the cube root of 25 first. The cube root of 25 is approximately 2.924.

Next, we add 15 to the cube root of 25.

15 + 2.924 = 17.924

To round to the nearest tenth, we look at the digit in the hundredth place, which is 2. Since it is less than 5, we round down.

Therefore, the answer is approximately 17.9.

So, the correct answer is 17.9.
