Answer:
11in
Step-by-step explanation:
a^2+b^2=c^2 when c is the hypotenuse
10^2+sqrt21^2=c^2
100+21=c^2
121=c^2
11=c
60%, 900/1500 would be .6 and in terms of percent would be 60.

You can find the volume by using the formula of density

where d is the density, m is the mass and v is the volume
You have to solve the formula for v like this:

you have the density and the mass so you just have to replace the variables in the formula with the values they are giving you, like this:

The volume of the stone is 7ml
