The correct statement is B
Answer:
23 Pa
Step-by-step explanation:
According to ideal gas law, PV = nRT. If V is constant, then:
P/T = P/T
Remember that P and T are absolute. So °F must be converted to either Rankine or Kelvin.
To convert °F to Rankine, add 459.67.
30°F + 459.67 = 489.67 R
80°F + 459.67 = 539.67 R
21 Pa / 489.67 R = P / 539.67 R
P = 23.1 Pa
Rounded to two significant figures, the pressure is 23 Pa.
Answer:
The correct option is;
B. s ≥ 12 - t, s ≤ 30 - t, s ≤ 24 - 0.66·t
Step-by-step explanation:
Answer:
x= 9/a
Step-by-step explanation:
Multiply the two desired probabilities to find the answer.
5/12 is the probability for the plain pencil since there are 5 pencils out of 12 total items.
1/2 is the probability for the colored pencil since there are 3 colored pencils out of 6 total items. 3/6 simplifies to 1/2.
5/12*1/2= 5/24
Final answer: 5/24
