The number of bags of mulch that is needed to cover the playground is 3,605 bags.
<h3>How many bags of mulch is needed?</h3>
The first step is to determine the volume of the surface of the city playground. The volume is the product of the length, width and height of the playground.
Volume = length x width x height
4 x 40.5 x 66.75 = 10,813.50 inches³
The second step is to determine the number of bags of mulch that is needed to cover the surface of the playground.
Number of bags of mulch = volume of the playground / volume one bag can cover
10,813.50 inches³ / 3 = 3,604.5 bags ≈ 3,605 bags

The slopes of perpendicular lines are negative reciprocals
parallel lines have the same slope
The notation V(r) actually gives the volume of air inside the basketball. V(r) is volume as a function of radius, r It can be written as: V(r) = 4/3πr³ So, for any value of r, we can get the volume V. For, example, when r = 7cm we can say; V(7) = 4/3 x 22/7 x 7³ = 1437.33 cm³
Answer:
Larger rocket: 36 kiloliters
smaller rocket: 24 kiloliters
Step-by-step explanation:
Lets assign the letters: "L" to the number of kiloliters the "Larger" rocket gets, and "S" to the number of kiloliters that the "Smaller" rocket gets.
We can create two equations from the words given in the problem:
First equation: <em>A total of 60 kiloliters is to be used for "L" plus "S"</em>:
which gives us: 
Next equation comes from the words: "<em>The smaller rocket receives 12 kiloliters less than the larger rocket</em>"
which gives us: 
Now we can use this last equation to replace for the "S" unknown in the first equation (and thus reducing the problem to one equation with one unknown (L), that one can easily solve):
Therefore the amount of fuel that the larger rocket gets is 36 kiloliters.
And using the equation "S = L - 12" we get: 
Which tells us that the smaller rocket gets 24 kiloliters of fuel.
$17.92 is the total before tax. The tax price was $1.16. After tax the total is $19.08
