QR has the endpoints Q(–10, 7) and R(1, –4). Gabrielle found the x-coordinate of the point that partitions the directed line segment QR in the ratio 2:3. Her work is shown below.
1. x = (x2 – x1) + x1
2. =(1 – (–10)) + (–10)
3. =(11) – 10
4. = =
The x-coordinate of the point P that partitions the directed line segment QR in the ratio 2:3 is , or
–5.6.
The y-coordinate of the point P is
.

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?
