A rectangular tank is 39feet long, 25 feet wide 18 feet high there is 11 feet of water in the tank if a valve is open at the bot

Aliun [14]

Answer:

1596.2 ft/m

Step-by-step explanation:

Data

height of water, h = 11 ft

acceleration of gravity, g = 32.17 ft/s²

Given that 60 seconds are equivalent to 1 minute:

g = 32.17 ft/s² * 60² s²/1 min² = 115812 ft/min²

From Bernoulli's theorem:

velocity = √(2gh)

velocity = √(2*115812*11)

velocity = 1596.2 ft/m

The point (7, 8) is the solution of which of the following systems of equations?

Alex73 [517]

Option 4

Verification:-

$\\ \sf\longmapsto x-7y=-49$

$\\ \sf\longmapsto 7-7(8)=-49$

$\\ \sf\longmapsto 7-56=-49$

$\\ \sf\longmapsto -49=-49$

And

$\\ \sf\longmapsto 10x+9y=142$

$\\ \sf\longmapsto 10(7)+9(8)=142$

$\\ \sf\longmapsto 70+72=142$

$\\ \sf\longmapsto 142+142$

Hence verified
