Correction

A student measures the mass 8cm3 block of brown sugar to be 12.9g. what is the density of the brown sugar

Explanation:

Density is defined as mass per unit volume of an object expressed as where is the density, m is the mass of sugar and v is the volume of the sugar. Considering that the volume is given as 8cm3 for sugar then we substitute this for v and mass of 12.9 g we substitute for g then the density will be

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

answer is slate

hope this
