Direct Variation<span>. Directly Proportional. A relationship between two variables in which one is a constant multiple of the other. In particular, when one variable changes the other changes in proportion to the first. If b is directly proportional to a, the equation is of the form b = ka (where k is a constant).</span>
The answer is: D) 115
The explanation is shown below:
1. You have that the frequency with which a cricket chirps varies directly with the temperature, which you can express it as following:
Where is the frequency with which a cricket chirps, is the temperature and is the constant of proportionality.
2. If the cricket chirps 100 times per minute in 80° weather, you can calculate as below:
3. Therefore, the frequency in 92° weather is:
Answer:
<u><em>
63</em></u>
Step-by-step explanation:
Rewriting input as fractions if necessary:
3/7, 1/9
For the denominators (7, 9) the least common multiple (LCM) is 63.
LCM(7, 9)
Therefore, the least common denominator (LCD) is 63.
I’m not quite sure if you are saying each side is 7 or 77 so I did both.
If the side length is 7, then 9.9 is the answer.
If the side length is 77, then 108.9 is the answer.
Answer:
The 3rd quadrant, where the x and y are both negative.
