Which of the following is √47 to the nearest tenth? A. 6.9 B. 8 C. 68.5 D. 9.2
The square root of 47 is between 6 and 7. The number 6.9 is the nearest tenth to the square root of 47, so the answer is A. 6.9
To find the square root of 47 to the nearest tenth, we can use a calculator or the approximation method.
First, let's start with option A: 6.9
6.9 squared is equal to 47.61, which is greater than 47.
Next, let's move on to option B: 8
8 squared is equal to 64, which is greater than 47.
Now, let's try option C: 68.5
68.5 squared is equal to 4682.25, which is much greater than 47.
Finally, let's check option D: 9.2
9.2 squared is equal to 84.64, which is greater than 47.
Based on our calculations, we can conclude that none of the given options is the square root of 47 to the nearest tenth.
To find the square root of 47 to the nearest tenth, we can use a calculator or a mathematical formula. Let's break it down step by step:
1. Start by finding the square root of 47 using a calculator. The square root of 47 is approximately 6.8556546004.
2. Now, we want to round this value to the nearest tenth. The tenths digit is the first digit after the decimal point. In this case, it is 8.
3. Since 8 is greater than or equal to 5, we round up the preceding digit. Therefore, the square root of 47 to the nearest tenth is 6.9.
So, the correct answer is A. 6.9
