3:4

16

Step-by-step explanation:

Remember how I said the ratios of the areas equals the ratio of the lengths squared, like how the area equals the length squared?

You can use that here too.

If the ratio of the lengths must square to equal 9:16,

the ratio of the length should be sqrt(9):sqrt(16) = 3:4

Also, x should be 4/3 times 12 = 16.

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
