A sofa regularly sells for 860. The sale price is 670.80. Find the percent decrease of the sale price from the regular price
andre [41]

Answer:

-22%

Step-by-step explanation:

The percent decrease can be found by subtracting the original amount from the sale price. Divide the result by the original price and multiplying the decimal by 100 for the percent.

670.80 - 860 = -189.2

-189.2/860 = -0.22

-0.22*100 = -22%

ABCD is a Rhombus with side length 10 cm. Angle ADC = 40. DAC is a sector of a circle with center D. BAC is a sector of a circle
Natasha_Volkova [10]

The value of the <em>shaded</em> area is approximately 34.907 square centimeters.

<h3>How to calculate the area between a rhombus and a circle</h3>

According to the description in statement we prepared a representation of the figure in the image attached below. The <em>shaded</em> area is equal to the area of the <em>circle</em> sector (A), in square centimeters:

A = \frac{\theta\cdot \pi \cdot R^{2}}{360} (1)

Where:

  • R - Length of the radius, in centimeters.
  • \theta - Angle of circle arc, in degrees.

If we know that \theta = 40^{\circ} and R = 10\,cm, then the area of the circle is:

A = \frac{(40)\cdot \pi\cdot (10\,cm)^{2}}{360}

A\approx 34.907\,cm^{2}

The value of the <em>shaded</em> area is approximately 34.907 square centimeters. \blacksquare
