Answer:
Prime numbers are whole numbers that has factors of 1 and itself.
Example: 2 is a prime because there is no way you could factor it except 1 and 2.
Composite numbers have more factors which also include 1 and itself.
Example: 50 is composite because it has factors more than 1 and itself.
5 is a factor of 50; 10 is a factor of 50.
So let's begin sorting.
<em>Prime: 7, 11, 31.</em>
Composite: 4, 8, 10, 27.
Hope this helps! :)
Answer:
A number line going from 0 to 4.5 in increments of 0.5
Step-by-step explanation:
This solution makes the most sense because 4.5 and 2.5 both have a decimal of 0.5

Answer:
y = (x -1)² -16
Step-by-step explanation:
Note the location of the vertex (point A) on the graph. Its x-coordinate is readily identifiable as 1. Its y-coordinate is some value between -15 and -20, closer to -15. (If you go to the trouble of finding the vertex coordinates, you discover they are (1, -16).)
Once you have determined what the vertex is, you can compare the offered answer choices to the vertex form ...
y = (x -h)² +k
where (h, k) are the vertex coordinates. That is, you are looking for an answer choice that is something like ...
y = (x -1)² -16
First you have to find 1/3 of the marbles. That means in the twelve marvels she has, there are three even groups. Divide twelve by three and you get four. So if each group is four, it is simple from here on out. If she started out with twelve and she lost 1/3 of them(4) it would be 12-4. You know this because lost is another for for subtract. 12-4=8. She has 8 marbles left.
