The density of the block of iron in
is equal to 7,880.
<u>Given the following data:</u>
- Volume of block = 0.4

To calculate the density of the block of iron in
:
<h3>What is density?</h3>
Density can be defined as mass all over the volume of an object or body. Thus, density is equal to mass per unit volume of an object.
<h3>How to calculate
density</h3>
Mathematically, the density of a substance is given by this formula;

Substituting the parameters into the formula, we have;

Density = 7,880

Answer:
7g - 3
Step-by-step explanation:
2g + 15 + 3g + g + g - 18
2g + 3g + g + g + 15 - 18
7g - 3
Answer:
<h2>f(x) = -3x - 1</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept, (0, b)</em>
The formula of a slope:

From the graph we have two points <em>A(-1, 2)</em> and <em>B(0, -1) → b = -1</em>.
Calculate the slope:

Finally:
