The natural numbers are presumed to have started before recorded history when humans began to count things. The Babylonians developed a place-value system based on the numerals for 1 (one) and 10 (ten). The ancient Egyptians added to this system to include all the powers of 10 up to one million.

An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it
A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.
An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:
The complete statement is
The word "twice" means ( 2* )
The words "the difference of indicate (-)

Step-by-step explanation:
The population density is 0.418 bacteria per mm².
A circle's area is the area that it takes up in a two-dimensional plane.
The formula for area of circle is, A = πr², where r is the radius of the circle. The unit of area is the square unit, such as m², cm², etc.
Given:
Radius= 40 mm
So, Area of petri dish = πr²
= 3.14x(40 mm)²
= 3.14 x 1600 mm²
= 5024 mm²
and, Population Density
= 2100 / 5024
= 0.418 bacteria per mm²
Hence, the population density is 0.418 bacteria per mm².

The number of games in which Fairlawn High scored between 15 and 36 points is 22.
To determine the number of games in which Fairlawn High scored between 15 and 36 points, we need to find the range of scores. If the range is inclusive of both endpoints, we subtract the lower score from the higher score and add 1. So the number of games is 36 - 15 + 1 = 22.
