The triagle clockwise from top-m-v-d

The triangle you are describing represents an equation involving the variables m, v, and d, which are commonly used to represent mass, volume, and density, respectively. The equations you have written are correct and represent three different ways to solve for one of the variables when the other two are known.

Let's break down the equations:

1. d = m/v: This equation represents the formula for density. It states that density (d) is equal to the mass (m) divided by the volume (v). To find the density given the mass and volume, you would divide the mass by the volume.

2. v = m*d: This equation represents a rearrangement of the density formula. It states that volume (v) is equal to the mass (m) multiplied by the density (d). This equation allows you to calculate the volume if you know the mass and density.

3. m = d*v: This equation is another rearrangement of the density formula. It states that mass (m) is equal to the density (d) multiplied by the volume (v). If you have the density and volume, this equation allows you to find the mass.

In summary, the triangle clockwise from top to bottom represents the relationships between mass, volume, and density, and the equations you provided are different rearrangements of the formula for density. To use these equations, you need to know the values of two variables and rearrange the equation to solve for the third variable.
