Answer:
83! :)
Step-by-step explanation:
It all equals 180.
So,
53+44+?=180
180-53-44=83! :)
83+53+44=180! :)
I believe it's a rational number, since it's an integer.
The direct path back forms a right triangle. Use the Pythagorean theorem:
X = sqrt(4^2 + 2^2)
X = sqrt(16 + 4)
X = sqrt(20) = 2sqrt(5)
X = 4.472
Round the answer as needed.
If it is
y is diretly proportional to x
y=kx
solve for y
3x+5y=0
5y=-3x
y=-3/5x
y=kx
constant of variation is -3/5
Answer:
60.0 L
Step-by-step explanation:
Ideal gas law:
PV = nRT
where P is absolute pressure,
V is volume,
n is number of moles,
R is gas constant,
and T is absolute temperature.
Since n and R don't change:
P₁V₁ / T₁ = P₂V₂ / T₂
(1.08 atm) (50.0 L) / (25 + 273.15 K) = (0.855 atm) V / (10 + 273.15 K)
V = 60.0 L
