Answer:8
Step-by-step explanation: plug in 0 for y then solve
30 300 000 is 30.3 million expanded.
The answer to your question is D: The result is a whole number that is neither prime nor composite.
Circumference of circular track, C = 0.5 miles = 0.5×5280 feet = 2640 feet.
We know, circumference in circle is given by :

( Here, r is radius i.e distance of centre from track )
Putting values in above equation :
2 × 3.14 × r = 2640
6.28 × r = 2640
r = 420.38 feet
Therefore, distance between centre and track is 420.38 feet .
Hence, this is the required solution.
Hey there! I'm happy to help!
Sum means you add. Let's call our number n.
n+15
We double the whole thing.
2(n+15)
This is equal to something.
2(n+15)=
Difference means you subtract.
2(n+15)=n-6.
Have a wonderful day! :D
