Answer:
triangular pyramid
Step-by-step explanation:
Let's make the central triangle the "base", or the bottom face, of our polyhedron. Try to visualise what will happen if we fold up the three triangles so that their top vertices meet at the center top (see diagram).
If we can do that, we'll see that it's a pyramid with a triangular base, so it's a triangular pyramid.
Answer:
Step-by-step explanation:
<span>10pi, </span>square root of 101, 9.92749, 0.99853
A) 2.025 x 10^14 kilometers / 225 million years
B) 2.25 × 10^8
C) 2.025 x 10^14 kilometers / 2.25 x 10^8 years
D) 2.025 x 2.25 = .9
E) 10^14 - 8 = 10^6
F) .9 x 10^6
Notes:
To write in scientific notation, move the decimal place over until there is only 1 number outside of it. (25,000 now equals 2.5) Then count how many spaces you moved over (25,000 moved over three zeros, and the five. That is 4 places) that is what you use to put over the 10 (2.5 x 10^4 = 25,000)
