Evaluate to the nearest tenth.
6 sqrt 10 subtract 9
sqrt 80 divided by sqrt 8
So, for #1, I got 10. Is it correct?
And #2, I got 3.2 Is it correct?
Thanks in advance for the replys,
The first answer is correct to the nearest tenth.
For #2, sqrt80/sqrt8 = sqrt10 = 3.16..., so 3.2 is also correct to the nerest tenth.
To evaluate the expressions to the nearest tenth:
1. 6√10 - 9:
To solve this expression, we first need to determine the value of √10, which is the square root of 10. To evaluate it, you can use a calculator or approximate it manually. By using a calculator, you'll find that √10 is approximately 3.16. Then, substitute the value of √10 back into the expression:
6 * 3.16 - 9
Evaluating this expression:
18.96 - 9 = 9.96
Therefore, the result is approximately 9.96 when rounded to the nearest tenth.
2. √80 / √8:
Similar to the first question, you need to find the values of √80 and √8. By using a calculator, you'll get:
√80 ≈ 8.94
√8 ≈ 2.83
Now divide the two values:
8.94 / 2.83
This calculates to:
3.16 ≈ 3.2 when rounded to the nearest tenth.
So, your answer for the second question is correct.
