Andrew has a pool in his backyard, and he wants to build a fence around the entire backyard.
Andrew's backyard is 9 meters wide and 15 meters long. It costs $45.00 per meter to install a wooden fence.

What is the total cost to put a wooden fence in Andrew's back yard?

$2160.00

Step-by-step explanation:

I think we are looking for the perimeter of Andrew's  fence here. The perimeter is 48 meters. 45 x 48 = $2160.00, which is the cost for the fencing.

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.

cool? what is the actuall ?
