arsen [322]

Answer:

275 units^2

Step-by-step explanation:

The formula for the area of trapezoid is:

Area=((b1+b2)/2)*h

In the given trapezoid, as it can be seen

b1=16

h=11

The lower base will be calculated using all the lengths in the lower base

b2=9+16+9

b=34

Putting the values in formula

Area=((16+34)/2)*11

Area=(50/2)*11

Area=25*11

=275 units^2

The graph shows the relationship between mass and volume for pure silver. Use the graph to determine the density of pure silver

Natalija [7]

Answer:

C. Slope and $10.49 g/cm^3$

Step-by-step explanation:

We're missing the graph itself, but I can make an educated guess:

- Assuming x = volume and y = mass:

$p = \frac{m}{v}$

density = mass/volume

x = volume = run

y = mass = rise

mass/volume = rise/run = slope

The slope of the line (assuming the graph is purely linear) represents mass/volume, which is the formula for density.

I had to Google the density of silver itself. Do the math from the graph for a more appropriate answer, as the graph may be less scientifically precise.
