What is the quadrilateral?

The definition of a quadrilateral is a planar form with four sides, four vertices, and four angles. Concave and convex are the two primary kinds.

Type of quadrilateral are:

Trapezoid.Rectangle.Parallelogram.Rhombus.Square.Kite.

A figure has vertices A = (0, 0), B = (1, 3), C = (0, 4), and D = (-1, 1).

The distance between AB is given as,

AB = √[(1 - 0)² + (3 - 0)²]

AB = √10 units

The distance between AD is given as,

AD = √[(-1 - 0)² + (1 - 0)²]

AD = √2 units

The measure of the adjacent sides is not equal. Then the MOST precise classification for figure ABCD will be a parallelogram.

Kimberly wants to get a backpack that cost $35 it is now on sale for 15% off she has to pay 7.5% sales tax what is the sales price of the backpack

Answers

Answer:

$44.26

Step-by-step explanation:

The computation of the sales price is shown below:

Its cost is $35

There is a sale off i.e. 15% off

And, the sales tax rate is 7.5%

SO, the sale price is

= $35 × 100 ÷ 85 + ($35 × 100 ÷ 85) × 7.5%

= $41.17 + $41.17 × 7.5%

= $41.17 + $3.09

= $44.26

Hence, the sales price is $44.26

it’s already simplified ig

The simplified fraction is 23/50.

We have,

To simplify the fraction 23/50, find the greatest common divisor (GCD) of the numerator (23) and the denominator (50), and then divide both the numerator and the denominator by the GCD.

The GCD of 23 and 50 is 1, as they have no common factors other than 1.

Now, divide both the numerator and the denominator by 1:

23 ÷ 1 = 23

50 ÷ 1 = 50

Thus,

The simplified fraction is 23/50.
