Jasmines pet guinea pig gained 8 oz. in one month. what is the integer to describe the weight her pet gained?
katrin [286]
We know that the pet Guinea gained 8 ounces in one month.

The question asks for the weight gained by Guinea in also one month.

Since both the described situation and the question both represent the same weight gained in the same duration, therefore, the required integer will be 8.

Answer: 8 ounces.

Decide whether ABCD with vertices A (3,8) B (6,5) C (5,4) , and D (2,7) is a rectangle a rhombus or a square
MissTica

Given:

The vertices of the quadrilateral ABCD are A(3,8), B(6,5), C(5,4), and D(2,7).

To find:

Whether the given quadrilateral is a rectangle, a rhombus or a square.

Solution:

Distance formula: The distance between two points is

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Using distance formula, the side lengths are:

AB=\sqrt{\left(6-3\right)^2+\left(5-8\right)^2}

AB=\sqrt{\left(3\right)^2+\left(-3\right)^2}

AB=\sqrt{9+9}

AB=\sqrt{18}

AB=3\sqrt{2}

Similarly,

BC=\sqrt{\left(5-6\right)^2+\left(4-5\right)^2}=\sqrt{2}

CD=\sqrt{\left(2-5\right)^2+\left(7-4\right)^2}=3\sqrt{2}

AD=\sqrt{\left(2-3\right)^2+\left(7-8\right)^2}=\sqrt{2}

The length  of diagonals are:

AC=\sqrt{\left(5-3\right)^2+\left(4-8\right)^2}=2\sqrt{5}

BD=\sqrt{\left(2-6\right)^2+\left(7-5\right)^2}=2\sqrt{5}

From the above calculation, we conclude that the given quadrilateral has two pairs of congruent opposite sides and equal diagonals.

Opposite sides of a rectangle are equal and its diagonals are also equal.

Therefore, the given quadrilateral ABCD is a rectangle.
