12 +28 =40 so 40 + 28 which is 68
Answer:
IQR=8
Step-by-step explanation:
write numbers in ascending order
3 6 9 10 12 13
find the middle, in this case, it's two numbers (10 and 12)
3 6 are on the left, find the middle between them; 3+6/2
4.5
12 and 13 are on the right, find the middle between them;
12+13/2
12.5
IQR=12.5-4.5
There are a couple of ways to write this. One, the simplest in my opinion, is this:
Five wholes and 96 hundredths. To write this it is:
5 96/100
However, this can be simplified and we know this because their GCF (greatest common factor) is 4. Divide each by 4.
= 24/25
(NOTE: DONT SIMPLIFY THE WHOLE NUMBER!)
The answer is D (2,016 square inches)
