You can just do 12/3 which = 4.
Broken down you will see,
3m = 1hr
6m = 2hr
9m = 3hr
12m = 4hr
So the answer is 4hours
Answer:
4
Step-by-step explanation:
20 percent * 20 =
(20:100)* 20 =
(20* 20):100 =
400:100 = 4

Step-by-step explanation:
7/x=12/14=6/7
x=49/6=8.167
<span>A. 3(4x - 4) - 7x = 12x - 12 - 7x = 5x - 12 yes
B. -3(4x - 4) - 7x = -12x + 12 - 7x = -19x + 12 no
C. 3(-4x + 4) - 7x = -12x + 12 - 7x = -19x + 12 no
D. -3(-4x - 4) - 7x = 12x + 12 - 7x = 5x + 12 no
Answer is A.</span>
Answer:
Flux = 16π
Step-by-step explanation:
The outward flux of F across the solid cylinder and z = 0 is
∫∫F*ds = ∫∫∫ DivF*dv
F = 2xy²i + 2x²yj + 2xyk
DivF = D/dx (2xy²) + D/dy (2x²y )
DivF = 2y² + 2x²
In cylindrical coordinates dV = rdrdθdz and as z = 0 the region is a surface ds = rdrdθ
Parametryzing the surface equation
x = rcosθ y = r sinθ and z = z
Div F = 2r²sin²θ + 2r²cos²θ
∫∫∫ DivF*dv = ∫∫ [2r²sin²θ + 2r²cos²θ]* rdrdθ
∫∫ 2r² [sin²θ + cos²θ]* rdrdθdz ⇒ ∫∫ 2r³ drdθ
Integration limits
0 < r < 2 0 < θ < 2π
2∫₀² r³ ∫dθ
(2/4)(2)⁴ 2π
Flux = 16π
