Answer:

Step-by-step explanation:
the formula for density is:

where d is density, m is mass, and V is volume.
solving for m in the last equation:

so if we find the volume and multiply it by the density
we will get the mass of the object.
The volume of a rectangular prism is given by:

where
is length,
is width and
is height:

we substitute to find the volume:

since the density has units of
we need the volume also in units of
, so we make the conversion using:

multiplying by 30:

and now we find the mass with the equation:

substituting d and V:

the nearest gram is: 
Answer:
<u>aₙ = aₙ₋₁ - 3</u>
Step-by-step explanation:
Given :
First term : <u>33</u>
Common difference = 30 - 33 = <u>-3</u>

Answer:
Step-by-step explanation:
580 - 58 (10% of 580) = 522
522 - discount price (20) = 502
Sally is paying 502 for her camcorder
990 - 247.5 (25% of 990) = 742.5
742.5 - 20 = 722.5
Sally is paying $502
Tabitha is paying $722.5
