10. Extended Response A company paid $9,000 for the rights to a software program. The payment was shared by ten
friends. Eight friends each received equal amounts,
and two friends each received double that amount.
(Lessons 6-8 to 6-11)
a: What amount of money was each of the eight friends'
share of the payment?
b. What amount did each of the other two friends receive?

step-by-step explanation:

the

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.

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
