Answer:
it's pretty simple y × 50
This is an example of a quadratic equation.
Whenever you see that the variable x is raised to the second power, you have a quadratic equation. The graph of this will look like the letter U and be called a parabola.
7/28 = 25/x
x = (25 × 28)/7
x = (25 × 4)
x = 100

Answer:
Volume of emerald = 294.22cm³
Step-by-step explanation:
Given that
Mass of emerald = 812.04grams
Density of emerald = 2.76grams/cm³
Volume = ?
The equation for this relationship is ρ = m / V in which ρ is density, m is mass (kg or g) and V is volume (cm³ or m³) making the density unit kg/m³ or g/cm³.
Therefore from
Density = mass/volume
Volume = Mass/density
i.e
Volume of emerald = Mass of emerald / Density of emerald
Volume of emerald = 812.04grams / 2.76grams/cm³
Volume of emerald = 294.2174cm³ ~294.22cm³
Volume of emerald = 294.22cm³
