5. The way I do these problems is setting up the equation as follows:
P1V1/T1 = P2V2/T2
The units of volume and pressure can be substituted as given, since they are in relation to one another, however, the final answer must match the units provided in the question. Also, temperature must be converted to Kelvins before the equation can be used.
V1 = 50 cm^3
P1 = 825 Hg/mm
T1 = 15C = 288K
P2 = 750 Hg/mm
T2 = 47C = 320K
V2 = ?
Solve:
P1V1/T1 = P2V2/T2
(825)(50)/(288) = (750)V2/(320)
143.23 = 2.34V2
V2 = 61.21 cm^3
Answer:
A
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
=
- 
Since both fractions have a common denominator of 3x, then subtract the numerators leaving the denominator, that is the numerators simplified
2x + 6 - (
- 8)
= 2x + 6 -
+ 8 = 2x -
+ 14
Hence
f(x) - g(x)
=
→ A
Answer:
x ≤ 63
Step-by-step explanation:
x/3-10 ≤ 11
Opposite of -10 is addition, 10+11= 21
Opposite of x/3 is multiplication 3, 21*3= 63
Answer:
A
Step-by-step explanation:
Percent go on 1 side
125
---- 125% out of 100%
100
35 next to 125% due to the unknown amount of votes on the other side
P goes under 3 and the answer is A
The square root of 6 is 2.449...
and that is closest to 3
