In order to clear out room for new merchandise, James decided to mark down some of the items for sale in his electronics store.
masya89 [10]

The correct answer is A, as the DVD player's price was reduced by $ 3.82 more than the stereo tuner's price.

In order to clear out room for new merchandise, James decided to mark down some of the items for sale in his electronics store, and he marked down DVD players by 36%, and he marked down stereo tuners by 22%, if DVD Players cost $ 41.60 after the markdown and stereo tuners cost $ 69.42 after the markdown.

To determine which item's price was reduced by more, and by how many dollars more was it reduced, the following calculation must be performed:

  • 100 - 36 = 64
  • 64 = 41.60
  • 100 = X
  • 100 x 41.60 / 64 = X
  • 4160/64 = X
  • 65 = X
  • 65 - 41.60 = 23.40

  • 100 - 22 = 78
  • 78 = 69.42
  • 100 = X
  • 69.42 x 100/78 = X
  • 6942/78 = X
  • 89 = X
  • 89 - 69.42 = 19.58

Therefore, the DVD player's price was reduced by $ 3.82 more than the stereo tuner's price.

A rectangular painting by Leonardo da Vinci measured 62cm along its diagonal. If the painting has a height of 42 cm how wide is
IRINA_888 [86]

ANSWER

45.6cm to the nearest tenth.

EXPLANATION

The diagonal of the rectangular painting is 62cm.

The height of the painting is 42 cm.

The height of the painting h , the diagonal, and the width of the painting forms a right triangle with the diagonal being the hypotenuse.

From the Pythagoras Theorem,

{w}^{2}  +  {42}^{2}  = {62}^{2}

{w}^{2} = {62}^{2} -  {42}^{2}

{w}^{2}  = 2080

{w} =  \sqrt{2080}

w = 4 \sqrt{130}

The width of the painting is 45.6cm to the nearest tenth.
