Answer:
A. usually 3 cards a year means you have little or no credit I believe
Answer:
A + B = C Ax = 2 Ay = 0 Bx = 0 By = 6
Ax + Bx = Cx = 2
Ay + By = Cy = 6
C = (2^2 + 6^2)^1/2 = 6.32
Tan Cy / Cx = 6 / 2 = 3
Cy at 71.6 deg
1. 0.2 g/mL
The relationship between mass, density and volume of an object is

where
d is the density
m is the mass
V is the volume
For the object in this problem, we have
m = 10 g
V = 50 mL
Substituting into the equation,

2. 10 mL
In this exercise we know:
- The density of the object: d = 2 g/mL
- The mass of the object: m = 20 g
Therefore, we can re-arrange the previous equation to find the volume:

And substituting values into the equation, we find

Answer:
I think B or C it won't lower so I'll go with B bc warm water is hotter than regular temp water
