Step-by-step explanation:
The car travels 600 feet in 20 seconds
=> 30 feet per second
The moyorcycle travels 300 feet in 12 seconds
=> 25 feet per second
Since 30 > 25, the car travels faster than the motorcycle.

Answer:
![f(3)=2\frac{2}{3}](https://tex.z-dn.net/?f=f%283%29%3D2%5Cfrac%7B2%7D%7B3%7D)
Step-by-step explanation:
![f(x)=8x\\f(3)=8(\frac{1}{3})\\f(3)=\frac{8}{3} \\f(3)=2\frac{2}{3}](https://tex.z-dn.net/?f=f%28x%29%3D8x%5C%5Cf%283%29%3D8%28%5Cfrac%7B1%7D%7B3%7D%29%5C%5Cf%283%29%3D%5Cfrac%7B8%7D%7B3%7D%20%5C%5Cf%283%29%3D2%5Cfrac%7B2%7D%7B3%7D)

Answer:
22
Step-by-step explanation:
Remark
Very nice little problem.
At first you think you need to go through the entire number system from 1 to 500. For example, you could do 12 as 1 2 3 4 6 12 So 12 does not add to the number of integers that have an odd number of factors.
But along the way if you check all the factors of the integers from 1 to 12, you notice something very odd. (No pun intended).
1 only has 1 factor which is odd (not even).
4 has 3 factors 1 2 4 which is odd.
9 has 3 factors 1 3 9 which is odd.
It turns out that there are 22 numbers from 1 to 500 that have an odd number of factors. They are the perfect squares between 1 and 500
Note
The factors of an integer include 1 and the integer itself
As a conclusion, try 36
1 2 3 4 6 9 12 18 36 There's 9 factors which is odd. So only the perfect squares have an odd number of factors.
