Unit rate is total price divided by quantity. This gives you the cost for 1 item.

Unit costs:

2.99 / 6 = 0.4983 each

4.49 / 9 = 0.4988 each

5.99 / 12 = 0.4991 each

3.49 / 8 = 0.4362 each

The Best Buy would be the one with the lowest unit price.

The Best Buy would be 3.49 for 8 candles.

alexandr1967 [171]

Answer:

<em>(a) 3 inches </em>

<em>(b) Her scale model drawing WILL fit on the piece of paper 8.5 by 7 inches</em>

Step-by-step explanation:

<u>Scaling </u>

We use scales to represent realities in reduced spaces. In the case of lengths or surfaces, the scale allows us to draw the shapes in normal sheets of paper.

(a)

Kelly's rock garden has a length of 6 feet. She uses a 1 inch:2 feet scale. this means that the model length is

6 feet*1 inch/2 feet = 3 inches

(b)

The width of the model is 5 inches, keeping the same scale it means the real length is

5 inches * 2 feet / 1 inch = 10 feet

The model will have 3 inches by 5 inches, it perfectly fits on any regular piece of paper

Which expressions represent the area of the entire shaded region, including the light and dark shading? select three options. 12

Alex Ar [27]

A triangle is a polygon. The total area of the figure can be represented by 12a, (6a+b), and 2b cm².

<h3>What is a triangle?</h3>

A triangle is a polygon with 3 sides and 3 vertices.

Since the area of a single triangle is a cm², and the shape is formed of 12 triangles, therefore, the area of the 12 triangles will be equal to,

$\text{Area of the complete figure} = 12 \times a = 12a\rm \ cm^2$

Given that the area of the complete dark portion is b cm², therefore, the area of the 6 triangles with a cm² of area each, and the black portion can be written as,

$\text{Area of the complete figure} = (6 \times a)+b = (6a+b)\rm \ cm^2$

As the dark portion also consists of 6 triangles with an area of a cm² each and the total sum of this dark area is b cm². Also, the light portion consists of 6 triangles with an area of a cm². Therefore, the total area can be written as,

$\text{Total area} = 6a+6a = b+b = 2b\rm\ cm^2$
