10.9544 rounded to the nearest tenth would be 11.0. When rounding to the nearest anything, remember to look at the number to the right of it. If it is greater or equal to five, round up. If the number is less than five, round down. In this situation, the number to the right of "9" (the position of the tenth) is five, which means we should round up, which would equal 11.
I hope this helped -- if it did, please thank, rate, and mark as brainliest! If you have any more questions or concerns, feel free to ask! Thank you, stay safe, and have a great rest of your day/quarantine! (i know it's hard, but we're almost through. we've got it!)
