Answer:
Circulatory system
Step-by-step explanation:
this is because the heart is part of the circulatory system
Remember that

So if
and
, then we know
.
Then use the Pythagorean identity to solve for cosine:

A. Let us first assume that the gas acts like an ideal
gas so that we can use the ideal gas equation:
PV = nRT
where P is pressure, V is volume, n is number of moles, R
is universal gas constant and T is absolute temperature
In this case, let us assume that nRT = constant so that:
P1V1 = P2V2
400 mm Hg * 400 mL = P2 * 200 mL
P2 = 800 mm Hg
<span>B. The collision of gas with the walls of the container
produces Pressure.</span>
The correct answer is 10.
In order to evaluate any composite function, you need to first put the value in for the inside function. In this case f(x) is on the inside along with the number 3. So, we input 3 in for x in f(x).
f(x) = 2x + 1
f(3) = 2(3) + 1
f(3) = 6 + 1
f(3) = 7
Now that we have the value of f(3), we can stick the answer in for the outside function, which is g(x).
g(x) = (3x - 1)/2
g(7) = (3(7) - 1)/ 2
g(7) = (21 - 1)/2
g(7) = 20/2
g(f(3)) = 10
Answer:
Step-by-step explanation:
emily : 16 + 22x....with x being the number of days
Lily : 24 + 18x
16 + 22x = 24 + 18x
22x - 18x = 24 - 16
4x = 8
x = 8/4
x = 2 <==== they will be on the same page in 2 days
16 + 22x = 16 + 22(2) = 16 + 44 = 60
24 + 18x = 24 + 18(2) = 24 + 36 = 60
and they will both be on page 60 <===
