<span>For the answer to the question above, according to Weber's law, the perceptible differences are proportional to the initial perception. So, with just a 10% increase in area was perceptible, but an increase of 1-9% in the area is considered imperceptible. The 9% increase in area reflected by 200 to 218 would be perceived as the same size as before.
The <u><em>answer is 218</em></u></span>
Answer:
18
3/4 equals to .75 if you multiply .75 with 21 you get 18
Answer:
Number 7: Solution U
Number 8: solution
Explanation:
Number 7: Given inequality is
First we simplify the equation and then we find critical points.
Critical points are :
Now we plot the points on number line and find the true and false solution. Please see the attach file fig 1 for number line.
We will check each interval for solution.
Let we take any interval and take any point between the interval and substitute into equation. We get >0 which is greater than 0.
This interval would be false.
Similarly, we will check each interval .
We get solution, U
Number 8: Given inequality is
First we simplify the equation and then we find critical points. Factor numerator and denominator. We get
Critical points are :
Now we plot the points on number line and find the true and false solution. Please see the attach file fig 2 for number line.
We will check each interval for solution.
Let we take any interval and take any point x=0 between the interval and substitute into equation. We get <0 which is less than 0.
This interval would be true.
Similarly, we will check each interval .
We get solution,
Answer: 9 regular soda
Step-by-step explanation:
Total soda served= 30
Regular soda= 30% of 30
= 30/100 × 30 = 9
9 regular soda were served.
