Answer:
925.235 or 23/567.6
Step-by-step explanation:
As per the concept of unitary method, the price of gasoline per gallon is $2.45.
To find the price of gasoline per gallon, we can use a simple mathematical calculation. The formula to calculate the price per gallon is:
Price per Gallon = Total Cost / Number of Gallons
Given that Denise paid $27.44 for 11.2 gallons, we can plug these values into the formula to find the price per gallon:
Price per Gallon = $27.44 / 11.2 gallons
Now, let's perform the calculation:
Price per Gallon = $2.45 (rounded to two decimal places)

In this question, we're trying to find the price of 1 gallon of gasoline. We know this because in the question, it says "per gallon", meaning that we are trying to find the price for 1 gallon.
We know that:
With the information above, we can solve the question.
In order to find how much 1 gallon of gas cost, we would divide 27.44 by 11.2
Divide:
When you're done solving, you should get 2.45.
This means that each gallon of gas costs $2.45
Set B: (-1, -6), (0, 2), (1, 2), (3, 6)
Set C: (2, 1), (4, 2), (2, 3), (8, 4)

Set C
b.
Set B
c.
Set A
d.
Set A and Set B
Please select the best answer from the choices provided
A
B
C
D
Answer:
d. Set A and Set B
Step-by-step explanation:
We have been given three sets:
Set A: (5, 2), (4, 3), (3, 4), (2, 5)
Set B: (-1, -6), (0, 2), (1, 2), (3, 6)
Set C: (2, 1), (4, 2), (2, 3), (8, 4)
Now we need to state about which of the following sets of ordered pairs represent a function.
We know that a function can't have repeated values in domain that is x-value can't repeat.
we see that set C has repeated x-value "2".
Then set C is not a function.
Hence correct choice is:
d. Set A and Set B
Answer:
A and B represent functions.
Step-by-step explanation:
In a function, any input (x-) value may have only one associated y value. If the same input appears more than once, we know immediately that the data do not represent a function.
A: The inputs are unique: {5, 4, 3, 2} so this is a function.
B: The inputs are unique: {-1, 0, 1, 3}, so this is a function.
C: 2 is used twice as input, so this is not a function.
