A tank initially contains 20 gallons of water. If water is flowing into the tank at a rate of 0.1 L/sec what is the volume of wa

IRISSAK [1]

The total volume of water in the tank after 3 mins 24.75 gallons.

<h3>New volume of water in the tank</h3>

The new volume of water that entered into the tank is calculated as follows;

V₁ = 0.1 L/sec x (3 x 60 s)

V₁ = 18 L

<h3>Volume of water in liters to gallon</h3>

1 liter = 0.264 gallons

18 Liter = ?

= 18 x 0.264

= 4.75 gallons

<h3>Total volume of water in the tank after 3 mins</h3>

V = 20 gallons + 4.75 gallons

V = 24.75 gallons

Does anyone know the the answer to the second algebra question? Will give brainiest

astraxan [27]

Answer:

$\sqrt[3]{x^{10} }[\tex]Step-by-step explanation:Exponential Rules:[tex]x^{a} + x^{b} = x^{a + b}$

$\sqrt[b]{x^{a} } =x^{\frac{a}{b} } Original Equation:[tex]\sqrt[3]{x^{10} } = x^{\frac{10}{3} } Answer:[tex]\sqrt[3]{x^{10} }[\tex]Convert the cubed root to a power. Cubed root = [tex]\frac{1}{3}$

$x^{3} x^{\frac{1}{3} }$

Convert them, so they have a common denominator - $\frac{1}{3}$

$\frac{3}{1} * \frac{1}{3}= \frac{9}{3}$

$\frac{9}{3} + \frac{1}{3} = \frac{10}{3}$

[tex]\sqrt[3]{x^{10} }[\tex] = [tex]x^{\frac{10}{3} } [\tex]
