This is a basic subtraction problem :-).
You will subtract how much money the mechanic gives to the supplier; which in this case will be $20, by the total amount of the parts which is $14.56.
20-14.56 = 5.44
Therefore, he will receive $5.44 in change for the transaction.
Answer:
x=5.37 cm
Step-by-step explanation:
we know that
The volume of the box is

where
B is the area of the base of the box
h is the height of the box
<em>Box 1</em>
we have that
The area of the base is


The volume of the Box 1
is equal to


<em>Box 2</em>
we have that
The area of the base is


The volume of the Box 2
is equal to
![V_2=[(x+1)^2(x+2)]\ cm^3](https://tex.z-dn.net/?f=V_2%3D%5B%28x%2B1%29%5E2%28x%2B2%29%5D%5C%20cm%5E3)
![V_2=[(x^2+2x+1)(x+2)]\ cm^3](https://tex.z-dn.net/?f=V_2%3D%5B%28x%5E2%2B2x%2B1%29%28x%2B2%29%5D%5C%20cm%5E3)


Equate the equation of Volume 1 to the equation of Volume 2




Solve the quadratic equation by graphing
using a graphing tool
The solution is x=5.37 cm
see the attached figure
7.79cm It is an equilateral triangle so it has 3 equal sides. That means each side is 9cm. <span>
Now draw a line from the top of the equilateral triangle to the base, and dividing it into two. You will have made two smaller triangles, with sides 9, 4.5, and h (the one you want to find).
A line drawn from the apex of an equilateral triangle to the midpoint of the base is perpendicular to the base, so you can use Pythagoras' Theorem!
4.5^2 + h^2 = 9^2
h = sqrt(9^2 - 4.5^2)
Therefore, the height is 7.79cm (2 decimal places)</span><span>
