With that information we can create the equation
10x + 5000 = 20x
where x is the number of earphones produced
10x is the cost to make each earphone, 5000 being the fixed costs of manufacturing, and 20x being the total revenue of selling each earphone for $20
Now to solve the equation:
subtract both sides by 10x
10x - 10x + 5000 = 20x - 10x
5000 = 10x
Now divide both sides by 10
5000/10 = 10/10 x
500 = x

▹ Answer
<em>435.20 square cm</em>
▹ Step-by-Step Explanation
Diameter = 12
Radius = 1/2d
Radius = 1/2 * 12
Radius = 6
A = πr(r +√h² + r²) =
A = π · 6·(6 + √16²+6²)
≈ 435.19869 → 435.20 square cm

The formula for the area of a triangle is A = (base · height)/2, but when we look at this problem, there's no base or height!
Looking at the triangle on the right, we can use the Pythagorean Theorem to find the height:
h² + 16² = 20²
h² + 256 = 400
h² = 144
h = ± 12
In this case, the height is 12 because you can't have negatives when you are working with lengths of sides and other things like this in geometry.
So now we've found the height, but we still don't know the full base! So, we can use the height that we just found to use the Pythagorean Theorem for the left triangle!
B² + 12² = 15²
B² + 144 = 225
B² = 81
B = ±9
So once again, our answer is just 9.
But, because the base is CB, we have to add:
b = 9 + 16
b = 25.
Now we have the base and height, so we can put them into our formula to solve for the area of the triangle:
A = (25 · 12) / 2
A = 300 / 2
A = 150
Answer:
SU = 16
Step-by-step explanation:
SU= 8x
ST = 6x
TU = 4
SU = ST + TU = 6x + 4 = 8x
SU - ST = 8x - 6x = 2x = 4
2x = 4
x = 4/2
x = 2
SU = 8x
SU = 8(2)
SU = 16
