Answer:

Aries originally had 48 cookies

Step-by-step explanation:

2 is half of 4

4 is 1/4th of 16

16 is 1/3rd of 48

check work by reversing steps:

Aries had 48 cookies, she gave 1/3 (16) to Ana. Ana gave 1/4th (4) to Edna, and Edna gives 1/2 (2) to Ruth.

Ruth has 2, so the work is correct.

Medians $\overline{dp}$ and $\overline{eq}$ of $\triangle def$ are perpendicular. if $dp= 18$ and $eq = 24$, then what is ${de}$

monitta

Denote by M the point of intersection of the medians.
Denote also the distance DM by x and the distance QM by y.
From the median properties of triangles we know that
$y=\frac{1}{3}\timesFQ=\frac{1}{3}\times24=8$
Also,
$x=\frac{2}{3}\times DP=\frac{2}{3}\times 18=12$
Since the medians are perpendicular, we deduce that:
$x^2+y^2=DQ^2\iff DQ=\sqrt{8^2+12^2}=14.4$
Then, since $DE=2\times DQ\text{ then }DE=2\times 14.4=28.8$
