Answer:
<h2> $2488.46</h2>
Step-by-step explanation:
This problem is on the mensuration of flat shapes.
firstly, we need to solve for the area of the garden.
given that the diameter d=24cm
the radius is d/2= 12cm
Therefore the area is expressed as
A= πr^2
A=3.142*12^2
A=3.142*144
A=452.448 cm^2
We are given that a square cm cost $5.50 to sandfill
therefore the entire garden will cost $5.50*452.448
$2488.46
Answer:
The proposed rule correctly works.
Step-by-step explanation:
As the original triangle has the vertices with the coordinates
From the given diagram, the image of the triangle has the vertices
A'(10, 4)
B'(5, 4)
C'(5, 0)
According to the proposed rule, the image should have the following vertices.
(x,y) ➝ (y+4, -x-2)
A(-6, 6) ➝ (6+4, -(-6)-2) = A'(10, 4)
B(-6, 1) ➝ (1+4, -(-6)-2) = B'(5, 4)
C(-2, 1) ➝ (1+4, -(-2)-2) = C'(5, 0)
So, the coordinates of the image of the triangle are correctly drawn as per the proposed rule.
Therefore, the proposed rule correctly works.
First, we translate the information that the question gives us:20+x is "twenty added to a certain number"(20+x)/5 is "the sum divided by five"1+12x is "one more than twelve times the original number"Putting it all together, we get the following equation:(x+20)/5 = 1 + 12xSolve for x:x+20=5(1+12x)x+20=5+60x20-5=60x-x15=59x15/59 = xTherefore, the original number was 15/59
