I need help on ratio of x-coordinates and ratio of y-coordinates
ad-work [718]

Answer:

Ratio of x-coordinates:

\frac{-1}{-2}=\frac{1}{2}

\frac{2}{4}=\frac{1}{2}

\frac{2}{4}=\frac{1}{2}

\frac{-2}{-4}=\frac{1}{2}

Ration of y-coordinates:

\frac{2.5}{5}=\frac{1}{2}

\frac{1}{2}=\frac{1}{2}

\frac{-2}{-4}=\frac{1}{2}

\frac{-2}{-4}=\frac{1}{2}

Step-by-step explanation:

The table is asking for the ratio of x-coordinates for each point (A, B, C and D) for both the image and pre-image.  The ratio is the image 'x' or 'y' value ÷ the pre-image 'x' or 'y' value.  Each ratio should be expressed in simplest form and should show the same pattern of dilation, or same scale factor.  In this case, the second figure is 1/2 the size of the original figure.

In​ 2006, the population of the country was 30.4 million. This represented an increase in population of 7.6 % since 2001. What w
Molodets [167]

Answer:

28.25 million

Step-by-step explanation:

Population of the country:

  • in 2001 - x million
  • in 2006 - 30.4 million

Population of the country as percent:

  • in 2001 - 100%
  • in 2006 - 100% + 7.6% = 107.6%

Write a proportion:

\dfrac{x}{30.4}=\dfrac{100}{107.6}

Cross multiply:

107.6\cdot x=30.4\cdot 100

Divide by 107.6:

x=\dfrac{30.4\cdot 100}{107.6}=\dfrac{3,040}{107.6}\approx 28.25
