Answer:
a. Set up a ratio.
b. Divide the numerator by the denominator to get the mass (in g) of 1 mL.

Answer: $6.24
Step-by-step explanation:
41.63-4.19= 37.44
37.44/6=6.24
The answer would be 20/12 or 1 and 2/3 as a mixed number :)
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.
