BRAINLIEST+ STARS!!

nasty-shy [4]

To find the density:

⇒ must find the relationship between the density, mass, and volume

⇒ $Density = \frac{mass}{volume}$

Let's examine the information given:

weight: 1890g
dimensions: 8cm * 5cm* 5cm

Let's first find the volume:

⇒ the volume is the dimensions multiplied together

$Volume = 8cm * 5cm * 5cm = 200cm^3$

LEt's calculate the density now:

$Density = \frac{1890g}{200cm^3} =9.45g/cm^3$

Answer: The density of the copper is 9.45g/cm^3 or Choice (A)

Hope that helps!

brad drank 7 cups of juice in 4.5 days which rate represents this situation? Question A 7 Cups/4.5days Question B 7days/4.5cups

Yuki888 [10]

The answer is A: 7 cups/4.5 days.

You see, the unit rate for this would be 1 cup/~0.6 day, so C and D would be incorrect (31.5 is too high for 7). Then, if you read it, it's seven cups, not days.

So, A.
