Answer:
B. 29.7
Step-by-step explanation:
All you have to do is find the area of the half circle (r² × 3.14 × ½) and subtract that from the initial area of the rectangle ( 9×4 ) After doing that it gives you 29.7ft².
Each student on average has 6 books.
<h3>
What is average?</h3>
- In layman's terms, an average is a single number chosen to represent a set of numbers, usually the sum of the numbers divided by the number of numbers in the set.
- The average of the numbers 2, 3, 4, 7, and 9 is 5, for example.
To find how many books on average each student has:
- To find the average, divide the total number of books by the total number of students.
- So, 14,400/2,400 = 6
Therefore, each student on average has 6 books.

Answer:
A. (3,0)
Step-by-step explanation:
When the equations are graphed, the solution is where the two graphs cross. For the red line and the blue line, the cross at (3,0)
We can check this by substituting x=3 into both equations and seeing if we get y=0
y = -x+3
y = -3+3
y =0
y = x-3
y = 3-3
y=0
In both cases, we got y=0.
Therefore (3,0) is a solution to both equations and since it solves both equations, it solves the system.
