After the decimal starts the the tenth place. In order to round to the tenth place, we need to know the hundredth place which is the 7. If the hundredth place is 5 or greater then we round up and if it's 4 or lower then we keep the tenth place the same number as it is before.
Since the hundredth place is greater than or equal to 5, we round up the tenth place to 6. If you have any questions then leave a comment. Good luck!
Answer 2
Answer:
12.57 rounded to the nearest tenth is 12.6 because the 5 is the tenth place and you have to look at the number to the right of that which is 7. 5 and up rounds up, so the 5 becomes 6 and the 7 disappears.
Tourist: "How many birds and lions do you have in your zoo?" Zookeeper:"There are 30 heads and 100 feet." Find the number of each animal. I need to know how to set this problem up in a system of linear equations. Thank you.
Answers
Each lion has 1 head. The number of lion heads is L . Each bird has 1 head. The number of bird heads is B. The total number of heads of all species is (L + B) = 30
Each lion has 4 feet. The number of lion feet is 4L . Each bird has 2 feet. The number of bird feet is 2B . The total number of feet of all species is (4L + 2B) = 100
The system of linear equations is:
L + B = 30 4L + 2B = 100 .
