Answer:
![D=3.5\ gr/cm^3](https://tex.z-dn.net/?f=D%3D3.5%5C%20gr%2Fcm%5E3)
Step-by-step explanation:
<u>Density</u>
The density of an object of mass m and volume V is given by
![\displaystyle D=\frac{m}{V}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20D%3D%5Cfrac%7Bm%7D%7BV%7D)
It can be expressed in common units like
or any other combination of proper mass [M] by volume [V] units.
The data provided in the question is
![m=200\ mg = 0.2\ gr](https://tex.z-dn.net/?f=m%3D200%5C%20mg%20%3D%200.2%5C%20gr)
![V=0.057\ cm^3](https://tex.z-dn.net/?f=V%3D0.057%5C%20cm%5E3)
Thus, the measured density is
![\displaystyle D=\frac{0.2\ gr}{0.057 \ cm^3}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20D%3D%5Cfrac%7B0.2%5C%20gr%7D%7B0.057%20%5C%20cm%5E3%7D)
![\boxed{D=3.5\ gr/cm^3}](https://tex.z-dn.net/?f=%5Cboxed%7BD%3D3.5%5C%20gr%2Fcm%5E3%7D)
We have expressed the result with 1 decimal place because the mass was measured to the nearest hundred milligrams (or one-tenth grams). Any further decimal is senseless because that precision comes from calculations, not from measurements.
Answer:
PR = 5 because LP + PR = LR according to the Segment Addition Postulate, and 7 + 5 = 12 using substitution
Step-by-step explanation:
The naming of the segments suggests that point P is between L and R, so that ...
LP + PR = LR
This corresponds to the last choice.
_____
<em>Comments on the alternate interpretation</em>
On the other hand, if point L is between P and R, then the segments are PL and LR. The Segment Addition Postulate would tell you that ...
PL + LR = PR
The Reflexive Property of Congruence would tell you that PL = LP. The Substitution Property would tell you LP can be substituted into this equation, making it ...
LP + LR = PR
and by the commutative property, ...
LR + LP = PR.
Multiple properties of addition and congruence are involved with this interpretation, which more or less matches the third choice. That is, the simple explanation of answer choice 3, by itself, is insufficient to explain why the length of PR should be considered to be 19, not 5.
