Answer:
The given situation is in direct variation.
The dependent variable is the distance covered and the independent variable is the number of hours.
Step-by-step explanation:
We are given the following information in the question:
Steve drove 300 miles in 5 hours.
After stopping for gas, he drove an additional 120 miles in 2 hours.
We calculate the ratios and if these ratios are equal then, we can say that the situation represent a direct variation.
For direct variation, the equation is of the form y = kx that is , we can write,
To check the ratio:
Thus, the given situation is in direct variation.
The dependent variable is the distance covered and the independent variable is the number of hours.
Answer:
All are rational except 2.36473....
Step-by-step explanation:
Any integers are rational, which means the top option (1000892) is rational.
Anything that can be written as a fraction is also rational, so is rational.
0.89 can also be written as a fraction as and 0.37373737... as
Therefore the only number that is not rational is the last, as it never repeats itself so can't be written as a fraction.
Hope this helps! Let me know if you have any questions :)
