Answer:

w = \frac{11}{35}

Step-by-step explanation:

To solve, \frac{3}{5w} - \frac{2}{7w} = 1, make both fractions on your left as one fraction by finding a common denominator.

Common denominator of 5w and 7w is 35w

Thus,

\frac{7(3) -5(2)}{35w} = 1

\frac{21 - 10}{35w} = 1

\frac{11}{35w} = 1

Multiply both sides by 35w

\frac{11}{35w}*35w = 1*35w

11 = 35w

Divide both sides by 35

\frac{11}{35} = \frac{35w}{35}

\frac{11}{35} = w

w = \frac{11}{35}

Answer: 108 ft³ 

Step-by-step explanation:

V= 4/3πr³ 

Facts:

Pi= 3

Diameter = 6

Step1; find the radius

Diameter is the length acaross the whole circle, but the radius is just 1/2 the circle. Therefore, if the diameter is 6, then the radius can be found by finding 1/2 of 6.

1/2 of 6= 1/2x6= 3.

R= 3

Step 2:  Plug in the numbers (into the formula)

PEMDAS

(exponents go first)

(then multiply from left to right)

V= 4/3πr³ 

V= 4/3x3x3³ 

V= 4/3x3x (3x3x3)

V= 4/3x3x27

V= (4/3x3)  x 27

V= 12/3x27

V= 4x27

V= 108

<u><em>Volume= 108 ft³ </em></u>

<u><em></em></u>

Hope this helps :)) Also brainliest would be appreciated, i worked pretty hard on this thanks! :)
