Answer:

Step-by-step explanation:

The equation is given: m/2 - 3n/4 = 16

1) When n = 8: m/2 - 24/4 = 16

m/2 - 6 = 16

∴ m = 2 X 22 = 44

2) When n = 20: m/2 - 60/4 = 16

m/2 - 15 = 16

∴ m = 2 X 31 = 62

3) When n = 32: m/2 - 96/4 = 16

m/2 - 24 = 16

∴ m = 2 X 40 = 80

4) When n = 44: m/2 - 132/4 = 16

m/2 - 33 = 16

∴ m = 2 X 49 = 98

5) When n = 48: m/2 - 144/4 = 16

m/2 - 36 = 16

∴ m = 2 X 52 = 104

An aquarium 2 m long, 1 m wide, and 1 m deep is full of water. Find the work (in J) needed to pump half of the water out of the
Nitella [24]

Answer:

W=2452.5 J

Step-by-step explanation:

The work is define as the integral of the force times distance. So we have:

W=\int^{a}_{b}Fxdx

Now, we can write the force in terms of density.

F=m*g=\rho Vg

V is the volume (V=2*1*1=2 m³)

So the work will be:

W=\int^{0.5}_{0} 2*1000*9.81*xdx=\int^{0.5}_{0} 2*1000*9.81*xdx=\int^{0.5}_{0}19620xdx=19620(\frac{x^{2}}{2})|^{0.5}_{0}

The limit of integration is between 0 and 0.5 because we want to pump half of the water out of the aquarium.

W=19620(\frac{x^{2}}{2})|^{0.5}_{0}=19620(\frac{0.5^{2}}{2})

W=2452.5 J

I hope it helps you!

Angle 2 is 2x+10 angle 4 is 4x+80 solve for x
Airida [17]

Answer:

15

Step-by-step explanation:

Angle 2 is 2x+10

angle 4 is 4x+80

and from the figure we can understand that when we add these 2 equations

We get

6x+ 90= 180

6x = 180 - 90= 90

6x= 90

x = 90 ÷ 6 = 15

answer = 15
