Cory remembers that his ATV had 4 gallons of gasoline in the tank on Monday. After driving a total of 40 miles duringthe week, he has 2 gallons of gas remaining. Find the slope of the graph representing this situation.

Answers

Answer:

-1/20

Step-by-step explanation:

For a graph like this you should make the gallons of gas on y-axis and the miles driven on the x-axis.

To find slope the formula is (y2-y1)/(x2-x1)

So in this case it is 2-4/40-0

-2/40

This reduces to -1/20

2/5 divided by 9/10A. 2/5
B. 4/5
C. 2/9
D. 4/9

actually 0.00444444444 as a fraction

Answers

it would be D because when you divide fractions, you multiply by the reciprocal of the fractions so 2/5 * 10/9. Then you simplify and get 4/9. Hope this helps!!!!!!!

What is the common ratio of the following sequence?
80, 20, 5,

Answers

The value of the common ratio of the sequence is,

⇒ 1 / 4

What is Geometric sequence?

An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.

Given that;

The sequence is,

⇒ 80, 20, 5,...

Now, We can find as;

The value of the common ratio of the sequence is,

⇒ 20 / 80

⇒ 1 / 4

Thus, The value of the common ratio of the sequence is,

⇒ 1 / 4
