Answer: Approximately 390,244 people per square mile
Work Shown:
Density = population/area
Density = (8 million people)/(20.5 square miles)
Density = 390,243.9024 approximately
This rounds to 390,244 since we're talking about the number of people.
Answer:
35
Step-by-step explanation:
Multiply 40 by 0.125 (12.5%) and you get 5
Subtract 5 from 40
35
Answer:
8 - i
General Formulas and Concepts:
<u>Algebra I</u>
<u>Algebra II</u>
Step-by-step explanation:
<u>Step 1: Define</u>
(3 - 4i) + (5 + 3i)
<u>Step 2: Simplify</u>
- Combine like terms (Z): 8 - 4i + 3i
- Combine like terms (i): 8 - i
Answer:
The solutions are -0.65 and 4.65.
Step-by-step explanation:
3x^2 - 12x = 9
Divide both sides by 3
x^2 - 4x = 3
To make a square with "x^2 - 4x", you need to have a "+ 4" after it so it can be simplified as (x-2)^2. So add 4 to both sides.
x^2 - 4x + 4 = 7
(x-2)^2 = 7
x - 2 = (square root) of 7
x = 2 (+/-) (square root) of 7.
x = {-0.65, 4.65}
The solutions are -0.65 and 4.65.
hope this helps:)sorry if it doesnt
