The volume of the pyramid is given by:

where
is the area of the base and
is the height.
We know that the height is:

Thus we need to find the area of the square at the base.
The perimeter of the square is:

this means that the length of the sides of the square is :

Now we can find the area of the base which the area of the square:

and finally we find the volume:

Step-by-step explanation:
X <= 20 means that x has to be less than OR equal to 20.
The first option is -100. That's less than 20, so this statement is true.
The second option is 10. That's also less than 20, so this statement is also true.
The third option is 20. This is equal to 20, so this is also true.
The fourth option is 21, which is greater than 20, so it's not true.
The fifth option is 45, which is greater than 20, so it's not true.
Sorry I answered so late, hope this helps even though you probably don't need it anymore.
Answer:
Yes
Step-by-step explanation:
Using Pythagorean theorem WHICH ONLY WORKS FOR RIGHT TRIANGLES,
a^2+b^2=c^2 where a and b are the two shortest legs.
12^2+35^2=c^2
144+1225=c^2
c^2=1369
c=
c=37
14x30=520. So, 520 divided by 24 = 21.6 . So, that means that you will need 22 packages of balloons and you will have 8 left over
