A. We know that 3,300,000 gallons enter the river in a second. So Shana says that 200,000,000 gallons enter in a minute. There's 60 seconds in a minute, so multiply 3,300,000 by 60. We get 198,000,000. If we were to round up, we would get 200,000,000, which is Shana's estimate. So her estimate is fairly correct.

B. Divide 200,000,000 by 4. We should get 50,000,000 quarts.

Round 10.95 to the nearest tenth
Serhud [2]

Hi there! To round 10.95 to the nearest tenth, we find the number in the tenth place, which is 9 and look one place to the right. Round up if the number is greater than 5 or equal to 5 and round down if its less than 5.

The answer is 11.0 or just 11.

<em>Ed: Explanation below.</em>

<em />

11.00

10.99

10.98

10.97

10.96

10.95 Look at the 9. Then look to the right. Do I round up or down?

10.94

10.93

10.92

10.91

10.90

If the number is greater or equal to 5, you round up. If the number is smaller than 5, you round down. 9 is greater than 5, so we round up.

Therefore, the answer is 11.
