So the picture below shows what the slant height is. It also shows that the pyramid can form a right triangle, in which we can use the pythagorean theorem, which is
.
But first, we have to find the height of this pyramid. The volume formula for a square pyramid is
. Since we know its a square pyramid, the length and width are going to be the same (12 ft), and we know that the volume is 432 ft^3. Using this info, we can solve for the height:

So now we can use the pythagorean theorem (remember to split the 12 by 2, since the right triangle has only half the length of the base). Our equation will be solved as such:

In short, the slant height is 10.8 ft.
Answer:
In three years can be into algebraic terms as: 3 + x. Where 'x' comes to be today's age.
For example, my age in three years will be:
If I'm 24 years right now, My age in three years = 3 + x ⇒ My age in three years = 3 + 24 = 27.

Step-by-step explanation:
c(t)=40:0≤t≤400
=40+0.50 (t-400):t≥400
Answer:
8x-4
Step-by-step explanation:
(3x-5)+(5x+1)
=3x-5+5x+1
=8x-4
Answer:
20
Step-by-step explanation:
Multiples of 10 are: 10, 20, 30, 40, 50, ... and so on.
Only one of them: 20 falls between 15 and 28.
Other conditions are also true for 20 - it has a factor that is an even number (all its even factors are: 2, 4, 10, 20) and it has a factor that is an odd number (all its odd factors are: 1, 5).
