By definition we have:
A triangular pyramid (also called tetrahedron) is a polyhedron whose surface is formed by a base that is a triangle and triangular lateral faces that converge in a vertex that is called apex (or apex of the pyramid).
It will be composed, therefore, by 4 faces, the triangular base and three lateral triangles that converge at the vertex.
Thus, the surface area is:
As = 4 * (50.5) = 202 in ^ 2
Answer:
The total surface area of the triangular pyramid is:
202 in ^ 2
Answer:
12?
Step-by-step explanation:
6/8 = 9/?
8 x 9=72
72/6= 12
Answer:
4.8 and 0.6
Step-by-step explanation:
Let x is the cost of the machine
4% = 0.04
x * 0.04 = <span>$1,823.94
x = </span><span>$1,823.94 / 0.04
x = $45,598.50
answer: </span>x-ray machine costs $45,598.50
<span> 4(y+3)+7=3
first you distribute the 4
4y+12+7=3
now add simplify each side
4y+19=3
subtract 19 from each side
4y=(-16)
divide each side by 4
y=(-4)
so -4 is your answer for y</span>
