Answer:
The answer is
<h2>21.45 g/cm³</h2>
Step-by-step explanation:
The density of a substance can be found by using the formula
From the question
mass of platinum = 214.5 g
volume = 10 cm³
It's density is
We have the final answer as
<h3>21.45 g/cm³</h3>
Hope this helps you
Answer:
b
Step-by-step explanation:
fairly certain it is b
When we write a line equation in the form
m is the slope of the line, and q is the y-intercept.
Since we want the y-intercept to be -3, our line will look like
In order to fix the slope, remember that two parallel lines have the same slope. So, the slope of the given line y=2x-5 is 2, and since we want a line parallel to this line, our slope will be 2 as well.
Plugging the values, we can finish the equation:
(-14x x y - 28y) + (6x^2 + 12x x y)
I hope this is right,

Answer:
Step-by-step explanation:
Given that the left angle =
The right angle across from it
The other two angles are x and x.
We know that the sum of angles at a point equals 360 degrees.
Therefore,
The value of x is approximately 38.5 degrees.
