A chain bracelet is found. It looks as though it might be made of either gold or of copper. When the bracelet is submerged in a graduated cylinder containing water, the volume of the water rises from 9.2 cm3 to 11.7 cm3. The bracelet has a mass of 45 g. Is the bracelet made of gold or copper? (Note: The density of gold is 19.3 g/cm3 and the density of copper is 8.92 g/cm3.)

step-by-step explanation:

answer

106 emergencies

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
