Answer:
nobody
Step-by-step explanation:
Humans have made use of natural numbers as long as humans have been around. Counting numbers are wired into our consciousness, as they are for many living things.
Research has demonstrated some plants can count up to 5 (generally, carnivorous ones). Honeybees have long been known to be able to count to 4, and recent research shows they can count higher. Fish can count; birds can count; as can many other species.
For most, it takes concentration and/or training to count beyond 4. We are born with an understanding of 1, 2, 3, more.
Nobody "invented" natural numbers.
_____
<em>Additional comment</em>
Prey species survive by being able to count predators. Some predators take advantage of the limitations of number recognition by hunting in groups larger than can be readily counted.
Answer:
After solving we get
Step-by-step explanation:
We need to solve the equation:
Solving:
Multiply 4x with terms inside the bracket
We need to solve above equation to find value of x
Using quadratic formula for finding value of x:
We have a=180, b=-28 and c=-57
Values of x are
So, After solving we get
Answer:People are able to hear footsteps because the sound made by a foot hitting the floor travels through the air to reach their ears. Is transmission
When light from the sun hits the sidewalk, the sidewalk becomes warmer. Is called absorption
Explanation:
Make sure you spell it right or it will not count it.
Answer:
Factor: Numbers we can multiply together to get another number.
Multiple: The product of one number multiplied by another.
Examples:
Factor Example: 3 × 5 = 15 therefore, 3 and 5 are the factors of 15.
-----------------------------------------------------------------------------------------------------------------
Mulitple Example: 4 x 1 = 4, 4 x 2 = 8, 4 x 3 = 12, 4 x 4 = 16, 4 x 5 = 20, 4 x 6 = 24
4, 8, 12, 16, 20, and 24 are multiples are 4.
