Answer:
$0.68
Step-by-step explanation:
To find the original price of the bracelet, write a proportion. $0.72 is the amount after a 6% tax rate. This means you paid 6% on the original price.
Find y by cross multiplying numerator and denominator of each fraction.
0.72(100) = 106y
72 = 106y
0.679 = y
0.68 = y
the area of the shaded part is 30. 89 cm²
<h3>How to determine the area</h3>
We have the shape to be a rectangle
The area of the shaded part should be;
Area of rectangle - 2 ( area of a semi circle)
The formula for area of a rectangle
Area = length × width
Area = 12 × 12
Area = 144 cm²
Area of a semicircle = 1/2 πr²
Area = 1/ 2 × 3. 142 × 6²
Area = 56. 56 cm²
Area of shaded part = area of rectangle - 2( area of semicircle)
Area of shaded part = 144 - 2(56. 56)
Area of shaded part = 144 - 113. 11
Area of shaded part = 30. 89 cm²
Thus, the area of the shaded part is 30. 89 cm²
