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:
the answer is 683/60
Step-by-step explanation:
just multiply 60 by 11 then add 23, or multiply the bottom number by the whole number then add the top number
Answer:
w=2 w = -9
Step-by-step explanation:
w^2 + 7w - 18 = 0
We can factor this equation
What 2 numbers multiply to -18 and add to 7
9*-2 = -18
9+-2 = 7
(w-2) (w+9) = 0
Using the zero product property
w-2 = 0 w+9 =0
w=2 w = -9
