Zina [86]2 years ago

Answer:

1120°

Step-by-step explanation:

Use the sum of interior angles formula:

180(n-2)

Where n is the number of sides.

In a nonagon, there are 9 sides, substitute 9 for n:

180(9-2)\\180(7)\\1260

Since our nonagon is a regular nonagon, all 9 angles measure the same, so each angle measures:

\frac{1260}{9} =140

Subtract 140 from 1260:

1260-140=1120

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:

<u>Data</u>

  • 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

12 (5x-1) = 7x (2x +2)
murzikaleks [220]
60x - 12 = 14x^2 + 14x

Subtract 60x & Combine

-12 = 14x^2+14x-60x
-12= 14x^2-46x
Add 12
0= 14x^2-46x-14
