Answer:
The answer is the first one - 8 square roots of 3
Step-by-step explanation:
Using formula is sufficient here.
In hexagon there are 6 same triangles.
You calculate the area of one of them by formula (1/2)*(2)*(4square root of 3/3)
You multiply that by 6 and simplify.
The answer is the first one - 8 square roots of 3
I hope I helped you and I will be happy If you mark my answer as brainliest.
Answer:
<u>True </u>Postulates are used to prove theorems.
<u>True</u> Two points determine a line
Step-by-step explanation:
A postulate, in mathematics, is a numerical property that cannot be directly proven, but it is still present, and no has exceptions. Postulates are often used to prove theorems, particularly in geometry. An example of this can be found in the midsegment theorem which states that the average of the two bases in a trapezoid gives the length of the midsegment. Depending on how one chooses to prove this, one could potenitally need the Parts-whole Postulate theorem. Thus, one can state that Postulates are used to prove theorems.
A line can be drawn to connect any two given points. Therefore, one can states that two points determine a line, as only two points are needed for one to draw a line between them.
Answer: There are 2.25×10³⁴ bacteria at the end of 24 hours.
Step-by-step explanation:
Since we have given that
Number of bacteria initially = 1
It triples in number every 20 minutes.
So, 
So, our equation becomes
We need to find the number of bacteria that it will contain at the end of 24 hours.
So, it becomes,
Hence, there are 2.25×10³⁴ bacteria at the end of 24 hours.
A door and pretty much anything that is 6.5 meters long.
