The coach of a baseball team separates the players into groups for drills.Each group has the same number of players. Is the tota
scZoUnD [109]

Answer:it is composite

Step-by-step explanation:

it is composite because if there is say 60 people on the team and he divided the groups amongst three people in each group then it would be 20 groups now that isn't prime see so it would be the same thing if the basketball coach separates the team into 10 groups and there's 60 people on that team that's not a prime number that would be a composite number so the answer is composite A prime number would be there's eight people in each group and he separates them into a group so that means that They would be 64 people on that team Now the book that I'm looking at right now doesn't tell you the people on that team and how much people there are on that team but it says there is a different amount from The number of teams to the number of people in the team see there's like eight people in the team and there is for groups so that means two people in each group so That means that the answer would have to be composite and not prime hope this helped somebody.

Explain how you would find the perimeter of this triangle.
Lynna [10]

Answer:

<em>15.4 </em>

Step-by-step explanation:

\frac{u}{4} = tan51.3° ⇒ u = 4tan51.3° ≈ 5

\frac{4}{v} = cos51.3° ⇒ v = \frac{4}{cos51.3} ≈ 6.4

<em>P </em>≈ 4 + 5 + 6.4 = <em>15.4</em>
