Answer:
the height is 20
Step-by-step explanation:
you should set a equation first:
12/15=x/25
and then cross multiply
to get x=20
Its impossible for there to be 2.5 children so im assuming you meant 25.
therefore
25= 100%
100/14= 7.1

E=mc^2 is one of the most recognizable equations in the world. In this task, you’ll attempt to understand it better. Let’s start with what the letters mean. The letter E stands for energy, the letter m stands for mass, and the letter c stands for the speed of light. The meaning of this equation is that you can completely convert mass into energy.
c^2 = E/m
c = (E/m)^(1/2)
Answer:
The total surface area is 896 
Step-by-step explanation:
<em>The square pyramid is a solid with square base and symmetric 4 triangular faces.</em>
Given that the square base is 14 m and height is 24 m.
The apex of pyramid, center of square and center of any edge of square make a right angled triangle.
Let that height if triangular face be "x".
by pythagoras theorm , 
x = 25 m
the area of square base is 
the area of each triangular side is <em>
</em>
such are 4 triangles, thus 
Thus the total surface area is 196 + 700 = 896
