Which statement about the net is true?

Mathematics
1 answer:
Schach [20]3 years ago
3 0
The net cannot be folded to form a pyramid because the faces that are not a base are not all triangles

If you fold this net up, you will get a triangular prism, NOT A PYRAMID.

A pyramid can have ANY polygon as its base, as long as all the other rest of the shapes are triangles.

Depending on the base, the number of triangles in a net of a pyramid must match the number of sides its particular base has.

For example, if you have a square pyramid turned into a net:
The base is a square (4 sides)
There should be 4 triangles on each side.

Because a pyramid is where all the triangles must meet up at a point.

Hope this helps!

Which equations can be used to solve for acceleration? Check all that apply.
kumpel [21]

Answer:

  • vi = vf – at
  • vf = at + vi

Step-by-step explanation:

Any equation in which a proper relation with acceleration is shown can be solved for acceleration. (The first equation improperly represents the relationship between vf, vi, and at.)

a = (vf -vi)/t

The probability that it will snow on the last day of January is 85%. If the probability remains the same of the first eight day
MrRa [10]

Answer:

Here, we have:

P(5 days snow in this 8 days) = 8C5 x (0.85)^5 x (1 - 0.85)^3 = 0.084

P(6 days snow in this 8 days) = 8C6 x (0.85)^6 x (1 - 0.85)^2 = 0.238

P(7 days snow in this 8 days) = 8C7 x (0.85)^7  x (1 - 0.85)^1  = 0.385

P(8 days snow in this 8 days) = 8C8 x (0.85)^8 x (1 - 0.85)^0 = 0.272

Add up those above, then the probability that it will snow AT LEAST five of those days in February:

P = 0.084+ 0.238 + 0. 385 + 0.272 = 0.979

Hope this helps!
