Answer 10

It means that the values of 25 and 30 are included in the times allowed.
When you say the word between, strictly speaking, it means more than one and less than the other, but it does not include the end values.

I'll give you an example.

If I say the class got test scores of between 80 and 95, that means their scores were from 81 to 94, including 81 and 94. Since 80 and 95 are not between 80 and 95, so 80 and 95 themselves are not included.

If I say the class got test scores between 80 and 95 inclusive, that means there were scores from 80 to 95, including 80 and 85 themselves. By using the word inclusive, I am no longer using the word between in its strict sense, and I am allowing the end values of 80 and 95 to be included.

Answer 11

finally lol

Answer 12

i got the answer thanx very much ok

Answer 13

When the statement tells you the cake can be cooked for 25 minutes to 30 minutes inclusive, that means the minimum time is 25 minutes, and the maximum time is 30 minutes.

This means you need to use less than or equal to and grater than or equal to.

\(25 \le t \le 30\)

Answer 14

Without the word inclusive it would be:

\(25 \lt t \lt 30\) This is not correct for your problem, it's only to show you the difference using the work inclusive makes.

Answer 15

ok thanx
