Pure gold and silver have densities of 19,300 kg/m3 and 10,500 kg/m3, respectively. If a jeweler uses 0.25 cm3 of metal to make a ring, then how much heavier (in grams) is the gold ring compared to the silver ring?

i can answer this question sweetie!

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

x-3y=4
