Answer:
$415.63
Step-by-step explanation:
it would have been 393.75, but he worked 5 hours overtime and got paid time and a half for it, meaning his normal pay plus half of it. (only for overtime tho).
so first calculate his normal pay:
40 × 8.75 = 350
then add overtime to it
8.75 × 5 = 43.75
43.75 × 1.5 = 65.625
65.625 + 350 = 415.625
round that and its 415.63!
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:
y=x^2+8x+13
Step-by-step explanation:
in standard form
y=x^2+8x+13
Answer:
452.16 cm³
Step-by-step explanation:
I assume the shape of the volcano is a cone.
V = (1/3)πr²h
r = d/2 = 12 in./2 = 6 in.
V = (1/3)(3.14)(6 in.)²(12 in.)
V = 452.16 in.²
