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
There can be more then 1 mode.
Sometimes, there is not even a mode.....and other times, there is 1 mode.
Answer: About 10.5 passed.
Step-by-step explanation:
1. Convert 50% into a decimal.
- First, convert 50% into a fraction, which is 1/2.
- Divide 1/2 by its numerator and denominator.
Hence, the answer is 0.5.
It moves in a horizontal line. Its 'y value' does not change.
This problem can
be directly solved by ratio and proportion.
We know that there
are 646,449 people for every 68.3 square miles, so:
646,449 people : 68.3
square miles = X : 570,374 square miles
We know that the :
symbol signifies division therefore,
646,449 / 68.3 = X
/ 570,374
X = 5,398,502,224
