Gosh I hope you didn't have to turn this in yet. I'll help you with 4 and 5.
If you want to find the unit rate, you're finding out how much money it is per ounce.
Divide your cost by the number of ounces.
So for example, 3.98 / 16.
After you get your answers, write them down. Whichever answer is the lower number is the better buy because each ounce costs less.
Answer:
x/6 = 3/9
9x = 18
x = 2
Answer: 2:6 as 3:9
If x:6 as 3:9, then x is equal to
---
Equation:
(x/6) = 3/9
x = 6(3/9)

Answer:
Total cost of cementing the path = Rs. 17,000.
Step-by-step explanation:
Let the square garden be ABCD
Let the region inside the garden (ABCD) be WXYZ.
<u>Given the following data;</u>
Length of sides of ABCD = 90m
Width of path = 5m
Cost = Rs. 10 per m²
Area of ABCD = 90 * 90
Area of ABCD = 8100m²
<em>To find the area of WXYZ;</em>
WX = WZ = 90 - (5 + 5)
WX = WZ = 90 - 10
WX = WZ = 80m
Area of WXYZ = WX * WZ
Substituting into the equation, we have;
Area of WXYZ = 80 * 80
Area of WXYZ = 6400 m²
Area of path = Area of ABCD - Area of WXYZ
Area of path = 8100 - 6400
Area of path = 1700 m²
Total cost of cementing the path = Area of path * cost
Total cost of cementing the path = 1700 * 10
<em>Total cost of cementing the path = Rs. 17,000</em>
