Acar used 130 gallon of gasoline on a 6 1/2 hour trip. the total distance of the trip was 365 miles. using this information determine the average number of gallon used in one hour

20 gallons per hour.

Step-by-step explanation:

Let be "x" the  average number of gallons that the car used in one hour.

You need to analize the information given in the exercise:

1. The total amount of gallons used by the car was:

2. The car consumes that amount in .

So, to convert the mixed number to a decimal number, you must divide the numerator by the denominator of the fraction and add the result to the whole number part. Then:

Set up the following proportion:

Finally, you must solve for "x" in order to find its value:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
