Answer:
Step-by-step explanation:
In order to determine the number of wax cubes needed to make the candle, we divide the volume of the pyramid by the volume of the cube. That is,
number of wax = volume of mold / volume of wax
The formulas are,
number of wax = (1/3)Ah / s³
Where A is the area of the base, in this case 9 cm x 9 cm which is equal to 81 cm². Substituting the known values from the given above,
number of wax = (1/3)(81 cm²)(10 cm) / (4 cm)³ = 4.21
Thus, approximate number of wax should be 4.21. If we are to round this off to the nearest whole number, we will get 5 (considering that we want rather to have excess than missing items)

The expression for the inequality is:
We need to find which line represents this inequality. To do that we will use the left side of the inequality and rewrite it as a slope-intercept form. Which is done below:
The line for this inequality is "-5x -2". Where the slope is -5 and the y-intercept is -2. We can graph it as shown below:
Total area of canvas used in the cunstruction of the tent = 551 - 1 = 550 meters square.
Area of a cone = πr(r + sqrt(h^2 + r^2))
22/7 * 7(7 + sqrt(h^2 + 7^2)) = 550
7 + sqrt(h^2 + 49) = 550/22 = 25
sqrt(h^2 + 49) = 25 - 7 = 18
h^2 + 49 = 18^2 = 324
h^2 = 324 - 49 = 275
h = sqrt(275) = 16.58
The volume of the tent is the volume of a cone with base radius of 7 meter and height of 16.58 meter.
Volume of a cone = 1/3 πr^2h
= 1/3 * 22/7 * 7^2 * 16.58 = 851.3 m^3
Assuming there 6-2 isn't in brackets, otherwise, it would be a tad more complex:
6 -2(x-4) = 22
6 -2x + 8 = 22
14 - 2x = 22
-2x = 8
-x = 4
x = -4
