Step-by-step explanation:
stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying, and solving the resulting equation
Get total lengths by multiplying:
10 x 12.6 = 126
6 x 16.1 = 96.6
Add the total lengths together and divide by 16:
126 + 96.6 = 222.6
222.6 / 16 = 13.9125
Rounded to 2 decimal places = 13.91
answer: 13.91
bearing in mind that the slope goes by several names
average rate of change
rate of change
rise over run
deltaY over deltaX
however, is the same cat disguised with a different costume.

1 cubic foot = 7.48 gallons
hence

unit conversion

3000 x 7.48 =22440
Rotation counterclockwise 90 degrees has the rule
(x,y) -> (-y,x)
So the image is obtained, according to the rule,
(2,3) -> (-3,2)
