Arecipe for crumb cake says to mix 3/8 cup of brown sugar and 1/3 cup of white sugar. from this sugar mixture, set aside 1/4 cup for the crumb topping. the remaining sugar mixture is used to make the cake. what amount of the sugar mixture is used to make the cake?

brown sugar=

white sugar=

you need to mix brown sugar with white sugar

+ = =

then it says you need to set aside 1/4 for the crumb topping from the previous sugar mixture that was  , so

- = =

The sugar mixture used to make the cake is

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.
