Answer: approximately 5.1818 pounds per square inch (psi)
========================================================
Work Shown:
P = pressure
T = temperature
The pressure is directly proportional to the temperature, which means P = k*T where k is some constant. As T goes up, P goes up as well, and vice versa. If P goes down, then T goes down too (or vice versa). In short, P and T go up together or go down together.
We're told that 6 psi (pounds per square inch) correspond to a temperature of 440 degrees F. This means P = 6 and T = 440 pair up. Let's use this P and T pairing to find k.
P = k*T
6 = k*440
6/440 = k
k = 6/440
k = 3/220
Therefore, the equation
P = k*T
updates to
P = (3/220)*T
--------------------
The last step is to plug in T = 380 to figure out the paired value of P
P = (3/220)*T
P = (3/220)*380
P = 5.1818 approximately
Answer: A

Answer:
63 points
Step-by-step explanation:
So you are trying to find out how many points you scored on the test when you got 90%,
we could do that by:
--------
70 (The totals points of the test) × 0.9 (The percentage converted into a decimal) = 63
--------
Let's double check,
so you got 63 out of 70, so when we divide 63 by 70, you would get 0.9.
0.9 converted into a percentage is 90%
Have a good day :)
False x is an angle Answer
Answer:
Step-by-step explanation:
parabola equation with vertex (0 , 0) and focus length |f| = 7
4*f*(x - h) = (y - k)²
4*7*(x-0)=(y-0)²
28x = y²
