Answer:

14\pi\ cm

Step-by-step explanation:

we know that

The formula to calculate the arc length of the circle is equal to

arc\ length=r \theta

where

r is the radius

\theta is the central angle in radians

In this problem we have

r=63\ cm

\theta=\frac{2\pi}{9}

substitute the values

arc\ length=63(\frac{2\pi}{9})

arc\ length=14\pi\ cm

Find the x-intercept and y-intercept for 8x+4y=16
Valentin [98]

Answer:

y-intercept = 4

x-intercept = 2

Step-by-step explanation:

you can divide the equation through by 4 and change into the y=mx+c form to find c, the y intercept so the y-intercept = 4.

for the x intercept make the y=0 (because the coordinate point where the line crosses the x axis must have y=0) and then you get 8x=16 so x=2

A 12-m3 oxygen tank is at 17°C and 850 kPa absolute. The valve is opened, and some oxygen is released until the pressure in the
sweet-ann [11.9K]

Answer:

Released oxygen mass: 15.92 kg

Step-by-step explanation:

ideal gas law : P*V=nRT

P:pressure

V:volume

T:temperature

n:number of moles of gas

n [mol] = m [g] /M [u]

m : masa

M: masa molar = 15,999 u (oxygen)

R: ideal gas constant = 8.314472 cm^3 *MPa/K*mol =

grados K = °C + 273.15

P1*V*M/R*T = m1

P2*V*M/R*T = m2

masa released : m1-m2 = (P1-P2) * V*M/R*T

m2-m1 = 200 * 10^-3 MPa * 12 * 10^6 cm^3 * 15.999 u / 8.314472 (cm^3 * MPa/K *mol) * 290. 15 K

m2-m1= 38 397.6 * 10^3 u*mol / 2412.44 = 15916.5 g = 15.9165 kg
