Can someone help me find answer.

A coral reef grew 7 meters.

Step-by-step explanation:

The prefix "milli" before any standard  unit such as meters, grams, or seconds and etc., It means it takes 1000 milli units to make 1 standard unit. Example:

1 meter= 1 millimeters.

To solve this problem you need to cross multiply:

7000 millimeters              1 meter    

                       multiply                 = 7 meters

1 month              1000 millimeters

Units that are the same and diagonal from each other cancel out.  

So the answer is: Last month, A coral reef grew 7 meters.

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.
