Arectangular piece of aluminum foil (density = 2.700 g/cm*3) is 25.70 cm wide and 28.32 cm long. it has a mass of 7.291 g. what is the thickness of the foil (height) in cm? put answer in correct sig fig.

Let's calculate the volume of the aluminum foil using the density



 

let's recall the volume of a rectangle formula

height x wide x long

we already have long and wide, and volume. so let's solve for the unknown

What are the options? i can you if you give them.

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
