Answer:

? = 55

Step-by-step explanation:

if we put the triangles onto of each other

side CT is on top of TR

126 ÷ 70 = 1.8

70 × 1.8 = 126

BT is on top of TS

so,

99 ÷ ? = 1.8

99 = 1.8 × ?

99 ÷ 1.8 = ?

55 = ?

55 × 1.8 = 99

A sample of gold has a mass of 579 g. The volume of the sample is 30 cm3. What is the density of the gold sample?

Ugo [173]

The density of the gold sample is 19.3g/cm³

Let the mass of the gold sample be represented by m

m = 579 g

Let the volume of the gold sample be represented by V

V = 30 cm³

Let the density of the gold sample be represented by ρ

The formula for the density is:

$Density = \frac{Mass}{Volume}$

$\rho = \frac{m}{V} \\\rho = \frac{579}{30} \\\rho = 19.3 g/cm^3$

The density of the gold sample is 19.3g/cm³
