Answer:
Option C i.e. 2 and 9, constants have a fixed value is a correct option.
Step-by-step explanation:
In algebra, a constant is basically a fixed value.
Sometimes, a constant is a number for a letter such as a, b, or c for a fixed number.
For example: in ''2x+7=3'', 7 and 3 are constants.
- <em>Please note that the number with variable x in the term is a coefficient.</em>
<em />
In our case:
Given the equation
Therefore, 2 and 9 are constants, having a fixed value.
Thus, option C i.e. 2 and 9, constants have a fixed value is a correct option.
A histogram is used to show the frequency of data, where the length of the bar represents the frequency.
<em>50 students drank the recommended amount of water.</em>
The recommended amount is given as:
See attachment for histogram.
From the histogram, we have the following observations
- <em>The lengths of all bars of the histogram are less than 48, except one.</em>
- <em>The length of the bar above 48 is 50.</em>
<em />
This means that: 50 students drank the recommended amount of water.
<em>Hence, the number of students is 50</em>

Step-by-step explanation:
Answer:
D)$42.00
Step-by-step explanation:
18 3/4 is equal to 18.75, so 18.75x2.80 is your original cost (52.5). After doing that, since 52.5=100% you are going to divide 52.5 by 5 since 20x5=100. So 20% is 10.5. 52.5-10.5= $42.00
