Question

The circumference of a woman’s basketball must be between 28.5 in. and 29 in., inclusive. What is a compound inequality that could show this?

Answer 1

Answer:

Greater than or equal to

Answer 2

Answer:

The ball should be BOTH greater than 28.5 AND less than 29 (although I don't think it's in inches...) Since it is not explicitly stated, let's assume we're talking about the basketballs diameter, D.

 

So now this may be written D > 28.5 and D < 29. Combining these two, we can write 28.5 < D < 29.

   

Also not explicitly stated is whether or not the basketball may be equal to 28.5 or 29. If, indeed, that is the case, then instead we may write this as D >= 28.5 and D <= 29, or combining, 28.5 <= D <= 29.

Hope this helps :D.
