Answer:
D. in quadrant III
Step-by-step explanation:
The signs of the coordinates tell you the point is located left of, and below, the origin (where the axes cross). That puts it in Quadrant III.
1 nickels =$0.05
1 dime= $0.1
let the number of nickels be x and that of dimes be y.
total number of coins is given by:
x+y=42
hence:
y=42-x.......i
total amount of cash will be:
0.05x+0.1y=3.30.........ii
substituting i in ii we get:
0.05x+0.1(42-x)=3.30
0.05x+4.2-0.1x=3.3
-0.05x=-0.9
x=-0.9/(-0.05)
x=18
hence the the number nickels is x=18, the number of dimes will be y=42-x=42-18=24
In slope intercept form this would just be: y=-3
The area of shape is the amount of space on it.
The cost to carpet the room is $224
From the floor plan (see attachment), we can divide the room into two shapes:
- <em>A 8ft by 6ft rectangle</em>
- <em>A 4ft by 2ft rectangle</em>
<em />
So, the area of the floor plan is:



The unit cost of carpet is <em>$4 per one square foot </em>
So, the cost to carpet the room is:


Hence, the cost to carpet the room is $224
