Answer: 5.18 pound per square inch
Step-by-step explanation:
According to pressure law, the pressure of a gas is directly proportional to the temperature
P1/T1 = P2/T2
where P1 is the initial pressure = 6 pounds
T1 is the initial to temperatures = 440°F
P2 is the final pressure = Z
T2 is the final temperature = 380°F
Thus, let final pressure be Z
P1/T1 = P2/T2
6/440 = Z/380
0.0136 = Z/380
Make Z the subject formula
Z = 380 x 0.0136
Z = 5.18 pound per square inch
Thus, the final pressure at 380°F is 5.18 psi (pound per square inch)
Your answer is: 128 pi.

Answer:
2 + (-6) ÷ 4 ⋅ 4
Step-by-step explanation:
Given in the question an expression,
2 + (3 - 9) ÷ 4 ⋅ 4
First step to solve this problem is to solve the arithmetic which is inside the brackets.
<h3>= 2 + (-6) ÷ 4 ⋅ 4</h3><h3>= 2 - 6 ÷ 4 . 4 </h3>
Anything in parentheses always come first when solving a problem.
