Cam you give the instructions???
Answer : C) 12.8 cubic cm
The volume ( v) of a gas in a container at a constant temperature varies inversely as the pressure (p)
If y is inversely proportional to x then 
where k is constant of proportionality
v is inversely proportional to p then 
the volume of a gas is 24 cubic centimeters when the pressure is 16 pounds
Given : v= 24 and p = 16. We need to find out k

Multiply by 16 on both sides
k = 384
Now we find out the volume under a pressure of 30 pounds

= 12.8 cubic cm
Answer:
y=-x+3
Step-by-step explanation:
rise is 3 and the run is 3
<span>(p + -3) * 6
Reorder the terms:
(-3 + p) * 6
Reorder the terms for easier multiplication:
6(-3 + p)
(-3 * 6 + p * 6)
(-18 + 6p)</span>
Step-by-step explanation:
Left hand side:
tan 203° + tan 22° + tan 203° · tan 22°
From angle sum identities, we know:
tan (α + β) = (tan α + tan β) / (1 − tan α · tan β)
Therefore:
tan (203° + 22°) = (tan 203° + tan 22°) / (1 − tan 203° · tan 22°)
tan (225°) = (tan 203° + tan 22°) / (1 − tan 203° · tan 22°)
1 = (tan 203° + tan 22°) / (1 − tan 203° · tan 22°)
tan 203° + tan 22° = 1 − tan 203° · tan 22°
Substituting:
1 − tan 203° · tan 22° + tan 203° · tan 22°
