Answer:
integers are closed under division
Step-by-step explanation:
Integers are not closed under division.Let us consider two integers i and j.
Then ![\[\frac{i}{j}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7Bi%7D%7Bj%7D%5C%5D)
need not necessarily be an integer. For example, 2 and 3 are integers but ![\[\frac{2}{3}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B2%7D%7B3%7D%5C%5D)
is not an integer. So the first option , namely, integers are closed under division is not true.
On the other hand, the remaining three options given are correct.
Answer:
h = 6 units
Step-by-step explanation:
h = 3r
Volume = 24π
πr²h = 24π
πr² * 3r =24π
3πr³ =24π
r³ =24π / 3π
r³ = 8 = 2*2*2
r = 2 units
h = 3r = 3 *2 = 6 units

Hey there! I'm happy to help!
Step 2 is incorrect. She added 4 and 2 first, but you are supposed to multiply and divide first. Then she multiplied 6 and 6, which is 36. Then she divided 36 and 2, which is 18, and then she subtracted 7, giving her 11. Step 2 is what threw the whole thing off.
Here is what Sandy should have done.
STEP 1: 6·4+2÷2-7
STEP 2: 24+1-7
STEP 3: 25-7
STEP 4: 18
I hope that this helps! Have a wonderful day! :D
