Answer:
0.571428571429 grams per cm³
Step-by-step explanation:
density = mass/volume
Let’s calculate the volume V of the pyramid :
V = (1/3)×base×height
    = (1÷3)×(5×7)×9
    = 105 cm³
Then
The density = mass/volume
                     = 60÷105
                     = 0.571428571429

Answer:
Yes
Step-by-step explanation:
All rhombuses are parallelograms, but not all parallelograms are rhombuses. All squares are rhombuses, but not all rhombuses are squares. The opposite interior angles of rhombuses are congruent. Diagonals of a rhombus always bisect each other at right angles.
 
        
             
        
        
        
Answer:
Choice C is correct
Step-by-step explanation:
The first step is to re-write the equations in exponential form.
The first equation can be written as;
 since the base is 10 and 4 the exponent.
 since the base is 10 and 4 the exponent.
The second equation can be written as;

The second step is to make N the subject of the formula in both equations.
Solving for N from this equation  , yields;
, yields;

Solving for N from the second equation  , yields;
, yields;

Therefore;
