Density is defined as the mass per volume. In problems 1, 2, and 4, you will be dividing the mass by the volume to determine density. Problem 3 asks for weight, so you will be multiplying volume by density to determine mass.

#1

40.5 g / 15 ml = 2.7 g/ml

#2

306.0 g / 22.5 ml = 13.6 g/ml

#3

0.789 g/ml * 200 ml = 157.8 g

#4

1896 g / 212.52 ml = 8.92 g/ml

(Since 1 cubic cm = 1 ml, we can find the volume by multiplying the lengths of the block's sides: 8.4 cm * 5.5 cm * 4.6 cm = 212.52 cm^3 = 212.52 ml)

$35.59 in pounds

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
