I think it should be D because if you look it is kind of common sense on how a triangle should look you should draw it out
Answer:
the class has 12 girls and 16 boys what is the ratio of the total students to boys in simplest form
Answer
$60+1/4c=$147.50
Step-by-step explanation:
makes $60 a day
1/4 of customer sales= 1/4 c
equal 147.50
so 60+ 1/4 c = 147.50

Answer: Choice B) 468 cm^2</h3>
============================================================
Explanation:
As the diagram shows, we have a triangular face with a base of b = 18 and height of h = 13. The area of this triangular face is:
A = 0.5*b*h
A = 0.5*18*13
A = 117 square cm or cm^2
This represents the area of one face, but there are 4 identical copies of this triangular face assuming this tetrahedron is a regular polyhedron. So we have a total surface area of 4*117 = 468 cm^2 which points us to choice B
This is the amount of paint you'll need to cover the outer surface of the pyramid, or you can think of it as the amount of wrapping paper needed. This assumes there are no gaps or overlaps.
