A 2 pound box of salt sells for $.89 and a 5 pound box sells for 2.09. What is the linear equation for this?

castortr0y [4]

Y = ax + b;

0.89 = a * 2 + b and 2.09 = a * 5 + b =>
=> 2.09 - 0.89 = a * 5 + a * 2 + b - b => 1.20 = 3 * a => a = 1.20 / 3 => a = 0.40;
b = 0.89 - 0.40 * 2 => b = 0.89 - 0.80 => b = 0.09;

y = 0.40x + 0.09 => 0.40x - y + 0.09 = 0 is the linear equation.

The combined volume of two identical cubes is 250 cubic centimeters. what is the measure of one cubes edge?

HACTEHA [7]

The measure of one cubes edge is 5 cm

<h3>Further explanation</h3>

To solve the above questions, we need to recall some of the formulas as follows:

Volume of Prism = Base Area × Height

Area of Square = (Side Length)²

Volume of Cube = (Side Length)³

Side Length of Cube = ∛ ( Volume of Cube )

Let us now tackle the problem !

<u>Given:</u>

The combined volume of two identical cubes is 250 cm³.

Let : Volume of The Cube = V₁ = V₂ = V

$V_1 + V_2 = 250 ~ \texttt{cm}^3$

$V + V = 250 ~ \texttt{cm}^3$

$2V = 250 ~ \texttt{cm}^3$

$V = 250 ~ \texttt{cm}^3 \div 2$

$V = 125 ~ \texttt{cm}^3$

$(\texttt{Side Length})^3 = 125 ~ \texttt{cm}^3$

$(\texttt{Side Length}) = \sqrt[3]{125 ~ \texttt{cm}^3}$

$(\texttt{Side Length}) = \boxed {5 ~ \texttt{cm}}$

<h2>Conclusion:</h2>

The measure of one cubes edge is 5 cm
