So 27 are in total
Minus 12 who have home computers
Therefore 27-12=15
15 students do not have home computers
Good luck
Answer:
a=5-b
now substituting to 2nd eqn
5-b-b=1
5-2b=1
4=2b
b=2
again,
a-2=1
a=3
Answer:
a simplified fraction
Step-by-step explanation:
Given: y = 100 - 2x
New: y = 100 - 2(x + 3)
= 100 - 2x - 6
= 94 - 2x
The original equation had a y-intercept of 100. The new equation has a y-intercept of 94. The y-value changes -6 units
Answer: -6
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
