## anonymous 4 years ago What is this rounded to the nearest tenth?

1. anonymous

$\sqrt{46}$

2. anonymous

Show work please.. I need a better understanding

3. anonymous

A. 6.6 B. 6.7 C. 6.8 D. 6.9

4. phi

are you allowed a calculator? if so, find sqrt(46) and write down the answer, including 2 numbers after the decimal point. then round that number.

5. anonymous

I can't I have a basic calculator :(

6. anonymous

online calculator

7. phi

type sqrt(46)= in the google search window |dw:1328287654901:dw|

8. anonymous

oh ya forgot about Google you can define and solve math in it.

9. anonymous

so does that make it B

10. anonymous

Phi?

11. phi

the sqrt(46) is about 6.78 but to round it the the nearest tenth you have to choose 6.7 or 6.8 look at a number line |dw:1328287934700:dw|

12. phi

or just follow the rule. look at the number after the 7. If it is 5 or bigger, make the 7 and 8

13. anonymous

I think it's 6.8. I'm pretty sure... Am I right?

14. phi

yes. if you started with 6.74, you would round it to 6.7 (because the 4 after the 7 is less than 5)

15. phi

but you have 6.78, and 8 is 5 or bigger, so round to 6.8
