3) Emilio wants to drown his sorrows by
eating the full pan of brownies his mom
left out on the counter to cool. In five minutes
he eats 1/3 of the pan. In the next five
minutes he eats 1/3 of the remaining pan. If
this pattern continues how much of the pan of
brownies will be left after 30 minutes?
Express your answer as a fraction. The table
provided may help you think it out.

Here is the table showing the remaining fraction of the pan after 30 minutes. The hint is to give you the computation at 10 minutes. You have to provide the rest.
Be careful! There's a lot of computation here!

4) Tim is using a computer program to create a diamond cut out.
What four equations can he use to create the diamond shown
here?
|
Find the equation of a line from cartesian coordinates for each of the 4 lines. You must find the y-intercepts and slopes of each line in each quadrant to write its equation: The 4 equations are:

5) Juni has a perfect evergreen, meaning its silhouette is always a triangle, in her back yard. She planted it 7 years ago. She has kept a growth chart measuring its base and its
height. This year she's having trouble measuring its height. If the tree follows the growth pattern in the chart, how tall should it be this year?
|
You only need the last 2 years, 2008 and 2011 to establish the linear pattern. Using X for the height in 2011, the ratio is:
