We are going to rewrite the ratio.
 We have:
 2 1/4: 6 3/4
 = (2 + 1/4) / (6 + 3/4)
 = (2.25) / (6.75)
 = (225/100) / (675/100)
 = (45/20) / (135/20)
 = (9/4) / (27/4)
 = 9/27
 = 3/9
 = 1/3
 Therefore, we have:
 A1 / A2 = 1/3
 A2 = 3A1
 A1: old patio
 A2: new patio
 Answer:
 
The area of the new patio is three times larger than the area of the old patio.

3. Quadrant 2

4. Quadrant 4

5. Quadrant 4

6. Quadrant 2

7. Quadrant 2

8. Quadrant 3

Step-by-step explanation:

For this problem, we just need to follow the pattern of positive and negatives associated with each quadrant.

The first quadrant (+, +)

The second quadrant (-, +)

The third quadrant (-, -)

The fourth quadrant (+, -)

Using these patterns we can state what order pair correlates to which quadrant.

(-2.5, 2.1) --> Q2

(1/2, 3/4) --> Q1

(-10, 13) --> Q2

(2.5, -5.5) --> Q4

(9, -10) --> Q4

(-12, 3.4) --> Q2

(-5/8, 5) --> Q2

(-6.4, -6.3) --> Q3

Cheers.

MrRa [10]

To find the unit price, divide the total price by the total weight.

4.60 / 2 = 2.30

So, the unit price is $2.30 per liter of milk.

Best of Luck!

<h3>Answer:  a = 100</h3>

=============================================================

Explanation:

There are n = 7 sides to this polygon (so it's a heptagon)

The interior angles add up to 180(n-2) = 180*(7-2) = 900 degrees.

So that means,

69+284+62+62+242+81+a = 900

800+a = 900

a = 900-800

a = 100
