Answer:
2596\83 =31.2
Step-by-step explanation:
Answer:

Step-by-step explanation:
The surface area of a square pyramid is the sum of the area of the squared base + 4 times the area of each triangular face, therefore:

where:
is the area of the base, where
L is the length of the base
is the area of each triangular face, where
h is the height of the face
Substituting,

For the model in this problem,
L = 12
h = 8
Therefore, the surface area here is:

No, r=3 can’t be a solution to this inequality. If we plug it in we get: 3+4>7 or 7>7 which is false. r should be more than 3.
Answer:
77/2 is 38.5 if that is what u were asking
Step-by-step explanation:
Okay. 10^12 is 1 trillion. 1 trillion * 7 is 7 trillion. 14 trillion / 7 trillion is 2. The national debt in 2010 is two times larger than in 2003. So that basically means that the national debt doubled from 2003 to 2010.
