If the mass of a material is 49 grams and the volume of the material is 7 cm^3, what would the density of the material be?
inysia [295]
The equation for density is:
density =  \frac{mass}{volume}

To help you remember - my teacher told us to remember "We <span>♡ density," and the heart stands for </span>\frac{m}{v}, or \frac{mass}{volume}. Cheesy, but it works!<span>
</span>
Back to the problem:
We know the mass if 49g and the volume is 7 cm^{3}, so plug these values into the equation for density:
density = \frac{mass}{volume}\\&#10;density = \frac{49\:g}{7\:cm^{3}} \\&#10;density = 7\:g/cm^{3}

Answer: The density is 7 g/cm^{3}

how many pounds of nuts selling for $9 per lb and raisins selling for $3 per lb should a person combine to obtain 60 lb of a tra
marta [7]
Let n be the number of lbs of nuts.
Let r be the number of lbs of raisins.
9n + 3r = 60 * 5 = 300 .............(1)
n + r = 60
n = 60 - r ...............(2)
Plugging the expression for n in (2) into (1) we get:
9(60 - r) + 3r = 300
which expands to:
540 - 9r + 3r = 300 .............(3)
Simplifying and rearranging (3) we get:
-6r = -240
Therefore r, the weight of raisins = 40 lbs
and the weight of nuts is 60 - 40 = 20 lbs
