Answer:

The correct unit price is $1.17 per pair of gloves. The error is she used number of dozens so, firstly convert it to number of pairs of gloves then divide.

Step-by-step explanation:

It is given 4 dozen pairs of gloves for $56.16.

So, unit price = Divide the price by number of pairs of gloves.

And 1 dozen =12

So 4 dozen =4*12=48 pairs of gloves

So, to find unit rate divide 56.16  by 48.

Unit price =\frac{56.16}{48}= $1.17

So, the error is she didn't convert the dozen to units.

That made mistake in finding unit price.

Answer:

1/12

Step-by-step explanation:

7 is one number out of 12 so if we take the one to the fraction is 1/12 aka simple easy math. if you want to simplify it would be impossible because 1 to 12 its impossible if it was 2/12 it would be 1/6, Sorry if i got the answer wrong.

Rectangle ABCD has vertices at A(−3,1),B(−2,−1),C(2,1), and D(1,3). What is the area, in square units, of this rectangle?
lilavasa [31]

Answer:

B.  10

Step-by-step explanation:

To find the area of this rectangle, we will simply find the distance AB and then find the distance BC, then multiply both together.

First, we will find the distance AB

A(-3,1),      B(-2, -1)

Using the distance formula;

|AB| = √(x₂ - x₁)² + (y₂ - y₁)²

x₁= -3               y₁ = 1                     x₂ = -2                   y₂ = -1

|AB| = √(-2 + 3)² + (-1 - 1)²

        =√(1)² + (-2)²

       = √1 + 4

        = √5

Next, we will find the distance BC

B(-2, -1)          C(2, 1)

Using the distance formula;

|BC| = √(x₂ - x₁)² + (y₂ - y₁)²

x₁= -2               y₁ =- 1                     x₂ = 2                   y₂ = 1

|AB| = √(2 + 2)² + (-1 - 1)²

        =√(4)² + (-2)²

       = √16 + 4

        = √20

Area of the rectangle ABCD = |AB| . |BC|

                                                =  √5 × √20

                                                 = √5×20

                                                   =√100

                                                    =10

                                                 

Area of the rectangle ABCD  =  10 square units
