What is the density of the rock?

Density = 0.64

Step-by-step explanation:

Density = mass/volume

We know that the mass of the rock is 16g and based on that picture, the volume of the rock is 25mL (because 75mL - 50mL = 25mL). So all we have to do is just plug in these values to the density equation above.

Density = 16 ÷ 25

Density = 0.64

Hope this helps! I apologize if I'm incorrect

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
