Answer:
10 families have cats
25 families have dogs
Step-by-step explanation:
The difference of ratio units is 5-2 = 3. The difference in pet counts is 15, so we can see that each ratio unit stands for 15/3 = 5 pets. Then ...
dogs : cats = 5 : 2 = (5·5) : (2·5) = 25 : 10
There are 10 families with cats and 25 families with dogs.

ANSWER
C. 38.83 miles per hour.
EXPLANATION
It was given that, the fuel economy of a car, measured in miles per gallon, is modeled by the function
We rewrite the function in the vertex form by completing the square.
Or
The vertex of this function is
Hence the maximum fuel economy is 25.57 gallons and this occurred at an average speed of 38.83.
The correct answer is C
Answer:
Step-by-step explanation:
1/20 is a tiny portion of the length that needs to be traveled. 20/20 is the whole length. If 1/20 gets traveled in 3/4 of a second, multiply 3/4 by 20 to see how long it takes to travel 20(1/20) which is equal to 1, the whole path.
20(3/4) = 15 seconds
