Multiple Response: Please select all correct answers and click "submit." Which of the following are among the five basic postula
Kazeer [188]

To Euclid, a postulate is something that is so obvious it may be accepted without proof.

A. A straightedge and compass can be used to create any figure.

That's not Euclid, that's just goofy.

B. A straight line segment can be drawn between any two points.

That's Euclid's first postulate.

C. Any straight line segment can be extended indefinitely.

That's Euclid's second postulate.

D. The angles of a triangle always add up to 180.

That's true, but a theorem not a postulate. Euclid and the Greeks didn't really use degree angle measurements like we do. They didn't really trust them, I think justifiably. Euclid called 180 degrees "two right angles."

Answer: B C

In a recent year there were about 400,000,000 mobile internet users. That same year, there were about 1.2 x 10^9 desktop interne
Naddika [18.5K]

Answer:

The number of desktop internet users are 3 times more than the number of mobile internet users.

Step-by-step explanation:

We are given the following in the question:

Number of mobile internet users = 400,000,000

400,000,000 = 4\times 10^{8}

Number of desktop internet user =

1.2 \times 10^9

Comparison of values:

=\dfrac{\text{Number of desktop internet user}}{\text{Number of mobile interet user}}\\\\=\dfrac{1.2\times 10^9}{4\times 10^8}\\\\=0.3\times 10\\=3

Thus, the number of desktop internet users are 3 times more than the number of mobile internet users.
