Darya [45]

Total volume of light-blue paint:

\left(4+\dfrac38\right)+\left(6+\dfrac18\right)=10+\dfrac48=10+\dfrac12

Divide by \dfrac14 to find how many containers he can divided this total into:

\dfrac{10+\frac12}{\frac14}=4\left(10+\dfrac12\right)=40+\dfrac42=40+2=42

so the answer is B.

What is the equation for density? D = d = m over v. D = d = v over m. D = d = m over v squared. D = d = one-half m v squared.mv2
Sophie [7]

Answer:

d = m / v.

Step-by-step explanation:

The density is a measure of the specific weight of a substance or object.

This is, the mass per unit of volume. Then, the average density is the ratio of the mass of a body to the volume it occupies in space:

The equation for density is:

\bar d=\dfrac{m}{V}

being m the total mass in the volume, and V the volume.
