1. Kelly has a rock garden with a length of 6 feet. She constructs a scale model of the rock garden using the scale 1 inch:2 fee
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

Guys I need the answers to number 16
Umnica [9.8K]
#16:  Let's clear the fraction on the way to solving this inequality for x.  By mult. the given inequality by 2, we'll get -2 (is greater than) x+4.  We want x to be positive.  So, leave it where it is.  Subtract 4 from both sides of this inequality.  We end up with -6 (is greater than) x, which is the same thing as x (is less than) -6.  What would the graph of that simple inequality look like?

Graph it.  (Hint:  The graph is a straight dashed line, and you must shade one side of it, but not the other side.
