Let us do it by converting the 0.4 to a fraction, it has one decimal, so we'll use one zero at the denominator.

and 9.21 to a fraction as well, two decimals, thus two zeros at the denominator then,

\bf 9.21\div 0.4\\\\
-------------------------------\\\\
0.\underline{4}\implies \cfrac{04}{1\underline{0}}\implies \cfrac{4}{10}\implies \cfrac{2}{5}\qquad \qquad \qquad \qquad 9.\underline{21}\implies \cfrac{921}{1\underline{00}}\\\\
-------------------------------\\\\
9.21\div 0.4\implies \cfrac{921}{100}\div \cfrac{2}{5}\implies \cfrac{921}{100}\cdot \cfrac{5}{2}\implies \cfrac{921}{20}\cdot \cfrac{1}{2}\implies \cfrac{921}{40}
\\\\\\
23\frac{1}{40}\implies 23.025

F'(-7, 13) was dilated by a scale factor of 2 about (-2, -5), the resulting image is___
AveGali [126]

The resulting image of the point F(x, y) = (- 7, 13) is F'(x, y) = (- 12, 31).

<h3>What is the resulting image of a point by rigid transformation?</h3>

In this problem we have a point that has to be transformed by a kind of rigid transform known as dilation, which is defined by the following equation:

P'(x, y) = O(x, y) + k · [P(x, y) - O(x, y)]             (1)

Where:

  • O(x, y) - Center of dilation
  • P(x, y) - Original point
  • P'(x, y) - Image
  • k - Scale factor

If we know that O(x, y) = (- 2, - 5), F(x, y) = (- 7, 13) and k = 2, then the resulting image is:

F'(x, y) = (- 2, - 5) + 2 · [(- 7, 13) - (- 2, - 5)]

F'(x, y) = (- 2, - 5) + 2 · (- 5, 18)

F'(x, y) = (- 2, - 5) + (- 10, 36)

F'(x, y) = (- 12, 31)

The resulting image of the point F(x, y) = (- 7, 13) is F'(x, y) = (- 12, 31).

Can you help me with this math problem and tell me how to do it?
Gemiola [76]

Let the number of songs Lou has = X

Kelly has 4 times as many as Lou, which would be written as 4X

Tiffany has 6 times as many songs as Lou, which would be written as 6X


The total number of songs = 682


You need to add all three people together to equal 682


So you would get:

X + 4X + 6X = 682 songs.

Combine all like terms ( 6x + 4x + X = 11x)

11x = 682


Now to solve for X divide both sides by 11:

x = 682 / 11 = 62


Lou = x = 62 songs.

Kelly = 4x = 4(62) = 4*62 = 248 songs.

Tiffany = 6x = 6(62) = 6 *62 = 372 songs.
