Answer:
Weber's Law
Step-by-step explanation:
- Weber's law States that it is a mathematical model of the difference threshold stating that the magnitude needed to detect a physical change in a stimulus is proportional to the absolute magnitude of that stimulus. Thus, the more intense the stimulus, the greater the change that must be made in it to be noticed.
Answer:
3 a^12 b^5
Step-by-step explanation:
Simplify the following:
(15 a^8 b^4 a^4 b)/5
15/5 = (5×3)/5 = 3:
3 a^8 b^4 a^4 b
3 a^8 b^4 a^4 b = 3 a^(8 + 4) b^(4 + 1):
3 a^(8 + 4) b^(4 + 1)
4 + 1 = 5:
3 a^(8 + 4) b^5
8 + 4 = 12:
Answer: 3 a^12 b^5
Answer:
33%
Step-by-step explanation:
Assuming the weight of the mixture to be 100g**, then the weight of ryegrass in the mixture would be 30g.
Also, assume the weight mixture X used in the mixture is Xg, then the weight of mixture Y used in the mixture would be (100-X)g.
So we can now equate the parts of the ryegrass in the mixture as:
0.4X + 0.25(100-X) = 30
<=> 0.4X + 25 - 0.25X = 30
<=> 0.15X = 5
<=> X = 5/0.15 = 500/15 = 100/3
So the weight of mixture X as a percentage of the weight of the mixture
= (weight of X/weight of mixture) * 100%
= (100/3)/100 * 100%
= 33%
To figure this out you would have to divide 180 by 10(which equals 18))
Answer:
b = 10
-2d = -38
x = -1.2
Step-by-step explanation:
b = 10 and x = -1.2 only have one variable. You can divide -2 to both sides for -2d = -38 getting d = 19.
0.1 = 0.1 have no variable meaning that any number can be correct in the equation
1/3 ≠ 1/3 has a cross in the equal sign meaning that there is no correct answer for the equation.
