Answer: The required number of miles traveled per gallon of gasoline is 31.2 miles.
Step-by-step explanation: Given that Elliot drove 202.8 miles and used 6.5 gallons of gasoline.
We are to find the number of miles that he traveled in one gallon of gasoline.
We will be using the UNITARY method o solve the given problem.
We have
Number of miles traveled in 6.5 gallon of gasoline = 202.8 miles.
Therefore, the number of miles that traveled in 1 gallon of gasoline is given by

Answer:
Option C
Step-by-step explanation:
Given that u-ai + bj and v-ci + dj are vectors
We have dot product
hence inner product of u and v. So option a is true
The dot product of u and v is a scalar is true because dot product is always a scalar
The dot product of u and v is a vector. is false because dot product is only a scalar and has no direction and hence cannot be a vector
The dot product of u and v is given by the expression ac+bd
True because we multiply corresponding i components and j components and add.
So only C is not true.
