Quadrilateral abcd has coordinates (3, 1), (4, 4), (7, 5), (6, 2). quadrilateral abcd is a
answer
a. square because its length and width are both square root of 10 units and adjacent sides are perpendicular
b. rhombus because its length and width are both square root of 10 units and adjacent sides are not perpendicular
c. rectangle because its length is two times the square root of 10 units, its width is square root of 10 units, and adjacent sides are perpendicular
d. trapezoid because it has only one pair of parallel sides

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?
