Need for a test You have 37.72 g of a material. What volume would this sample occupy if the material has the density listed below? *
5.55 g/cm^3

Step-by-step explanation:

Given data

mass m=37.72g

density=5.55 g/cm^3

volume v=?

We know that density is

density = mass/volume

Substituting into the expression we have

5.55 g/cm^3=37.72/v

cross multiply we have

5.55v=37.72

v=37.72/5.55

v=6.79cm^3

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
