D. Use the formula V=πr^2 h.
Answer:
It is A
From the x-value of 3 to the x-value of 8, the y-value goes down from 3 to -6
It was stated in the problem that a given volume of a is inversely proportional with the pressure of the system. It means that the as the volume increases, the pressure would decrease and as the volume decreases, the pressure would increase. We would express it as:
V α 1/P
To change it to an equality, we introduce a proportionality constant, k. We do as follows:
V = k/P
So, to determine what is asked, we need to first calculate for the value of k.
V = k/P
At V = 160 m^3 P = 108 cmHg
160 = k / (108)
k = 17280
Thus, at P = 87 cmHg
V = 17280 / 87
V = 198.62 m^3
Answer:
22.5 deg
Step-by-step explanation:
SOLUTION:
by putting x = 4y - 1 in the equation x + 2y = 11, we get;
=) 4y - 1 + 2y = 11
=) 6y = 11 + 1
=) y = 12/6
=) y = 2
Now that we got the value of y we can put the value in the equation x = 4y - 1.
=) x = 4(2) - 1
=) x = 8 - 1
=) x = 7
Hence, the value of x is 7 and y is 2.
