Answer:

Hiiiiiiii ! :) so here's a step by step explanation okay, starting with the first step below. Hope it helps you ! :) :)

Step-by-step explanation:

Begin with the volume of water:

V = πr²×h = π×(9m)²×2.5m = 636.17m³

Weight of water = 636.17×10³kg

G force on water = 9.8m/s²×636.17×10³kg = 6,234.49kN

Water's center of gravity is 2.75m below edge of pool.

(2.5m/2 = 1.25m, 4m - 1.25m = 2.75m)

Work = force × distance = 6,234.49kN × 2.75m = 17,144.85

Hope i helped. <3

Solve for m. m/9 + 2/3 =7/3

Nuetrik [128]

Answer:

m= 15

Step-by-step explanation:

$\frac{m}{9} + \frac{2}{3} = \frac{7}{3}$

To solve for m, start by moving the constants (numbers that are not attached to any variable) to the other side of the equation.

$\frac{m}{9} = \frac{7}{3} - \frac{2}{3}$

Simplify:

$\frac{m}{9} = \frac{5}{3}$

Multiply both sides by 9:

$m = \frac{5}{3} \times 9$

Crossing out 3 from the denominator and from 9:

m= 5(3)

m= 15

How do you do (2/3) (-4) (9)

DochEvi [55]

Answer:

Since 3 is evenly divided by 9, we can multiply just one term to get a common denominator. Multiply 2 by 3, and get 6, then we multiply 3 by 3 and get 9.

The United States govermoment produced about 10.25 billion pennies in one year. How is 10.25 billion written in scientific notat

Margarita [4]

In scientific notiation the number is noted as a number between 1 and 10 times 10 to whatever power is necessary to equal the original number so it needs to be 1.025 x 10^10 instead of 10.25.
