Answer:
$32.07
Step-by-step explanation:
I am not sure - are we seeing the full information about this problem ?
because the problem description is strangely vague and confusing, as it uses "total cost" two times for not the same thing ...
either total cost means including tax or not including tax. but it cannot mean both ...
I think the most likely understanding of this problem is that the first price is without tax, and now we need to calculate and add the extra 6% tax to get the really total price to be paid.
I will solve this now based on this assumption.
100% = $30.25
1% = 100%/100 = 30.25/100 = $0.3025
6% = 6×1% = 6×0.3025 = $1.815 ≈ $1.82
the total price is then calculated either by
100% + 6%
or by
106% = 100%×1.06 = 30.25×1.06 = $32.065 ≈ $32.07
in both cases we get the same result, of course.
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)

Answer:
B
Step-by-step explanation:
2x = log3 (y - 1)
