Conversational speech is 65 dB as a known fact.
Using math, dB = 10 log[10] ratio
10x => 10(1) = +10 dB
100x => 10(2) = +20 dB
base is 45 dB
If she gave all the kids in her class 1 piece of candy, and she had 7 left over, the equation is 97 - 7 = 90. There are 90 kids in her class.
Answer:
The Pythagorean Theorem is used for right triangles only, because it's a mathematical relation between the legs of the triangle and the hypothenuse, where each leg must be less than the length of the hypothenuse.
It's important to correctly identify each element of the triangle, that is, which sides are legs, and which side is the hypothenuse, because the Pythagorean Theorem has a specific order, that means, if we make a mistake identifying each element, then the result will be wrong.
For example, the expression
is the theorem, where
is the hypothenuse. This theorem states that the square of the hypothenuse (longest side) is equal to the sum of the square of the legs. So, if we call
a leg instead of the hypothenuse, the theorem won't work.
