You find a ring with a mass of 107 g. You fill a graduated cylinder up with 10 ml of water and put the ring into the cylinder. The water rises up to the 15 ml mark. What is the ring made of?

Platinum

Step-by-step explanation:

If the water rises by 5 mL then that is the volume of the ring, using this and the mass (107g) we can find the density of the metal using

Density = Mass/Volume

Density = 107g/5mL

Density = 21.4 g/mL

If we look at a density chart on google we can find that the metal with a density of 21.4 g/mL is platinum

a negative exponent is translated as follows:

so, we have

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
