Magnesium has a density of 1.071 g/cm3

. Aluminium has a density of 2.700

g/cm3
. An unknown metal has a mass of 15 g and a volume of 14 cm3
. Is the
unknown metal magnesium or aluminium? Show your work for complete marks.

Step-by-step explanation:

The density of the unknown metal is

mass / volume = 15 gm / 14 cm^3 = 1.0714 gm/cm^3    SO it is magnesium

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
