2 answers:
Answer:
The American consumed gallons of gasoline.
Step-by-step explanation:
We are given the following information in the question:
Gasoline consumed by the Americans = 320,500,000 gallons
We have to convert this number into scientific notation.
- Scientific notation is a method of writing very large or very small numbers.
- A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.
The above number can be written in scientific notation in the following manner:
Hence, the American consumed gallons of gasoline.

The equation of the line in the point-slope form is y - 15 = (x - 10)
Step-by-step explanation:
The point-slope form of a linear equation is , where
- m is the slope of the line, where
,
and
are two points on the line
∵ Point A = (10 , 15)
∵ The x-coordinate of the second point is 125% of x-coordinate
of point A
∴ x-coordinate of second point = × 10
∴ x-coordinate of second point = 12.5
∵ The y-coordinate of the second point is 75% of y-coordinate
of point A
∴ y-coordinate of second point = × 15
∴ y-coordinate of second point = 11.25
∴ The coordinates of the second point are (12.5 , 11.25)
Let us find the slope of the line by using the rule of it above
∵ = (10 , 15)
∵ = (12.5 , 11.25)
∴
Now we can write the equation
∵ The point-slope form is
∵
∵ = (10 , 15)
- Substitute these values in the form of the equation
∴ y - 15 = (x - 10)
The equation of the line in the point-slope form is y - 15 = (x - 10)
