\bf ~\hspace{5em} \textit{ratio relations of two similar shapes} \\\\ \begin{array}{ccccllll} &\stackrel{\stackrel{ratio}{of~the}}{Sides}&\stackrel{\stackrel{ratio}{of~the}}{Areas}&\stackrel{\stackrel{ratio}{of~the}}{Volumes}\\ \cline{2-4}&\\ \cfrac{\stackrel{similar}{shape}}{\stackrel{similar}{shape}}&\cfrac{s}{s}&\cfrac{s^2}{s^2}&\cfrac{s^3}{s^3} \end{array}~\hspace{6em} \cfrac{s}{s}=\cfrac{\sqrt{Area}}{\sqrt{Area}}=\cfrac{\sqrt[3]{Volume}}{\sqrt[3]{Volume}} \\\\[-0.35em] ~\dotfill

\bf s:s\implies 2:9\implies \cfrac{s}{s}\implies \cfrac{2}{9}=\cfrac{\sqrt{Area}}{\sqrt{Area}}\implies \cfrac{2}{9}=\sqrt{\cfrac{Area}{Area}} \\\\\\ \left( \cfrac{2}{9} \right)^2=\cfrac{Area}{Area}\implies \cfrac{2^2}{9^2}=\cfrac{Area}{Area}\implies \cfrac{4}{81}=\cfrac{Area}{Area}

Solve the following system by any method. –8x – 8y = 0 –8x + 2y = –20
madam [21]
This one is simple since we already have the two x variables.equal. All we have to do is subtract the equations from one another to get the answer.
So i will subtract the left side by the other left side and the right side by the other right side

-8x - 8y -(-8x + 2y) = 0 -(-20)

distribute negative sign

-8x - 8y + 8x - 2y = 0 + 20

do the math
- 10y = 20
Y = -2

plug t into an equation
-8x -8 (-2) = 0

-8x + 16 = 0
-8x = -16
x = 2
answer (2, -2)

I want to know if mammals usually have more
DENIUS [597]

The graph that would allow the comparison between the median number of teeth for mammals and reptiles easily is a Box Plot.

<h3>Median</h3>

The median of a set of data is the midpoint of values in a data set. It shows the value that divides the data set into two halves.

<h3>Box plot</h3>
  • A box plot is a type of graph used in data analysis to visualize the distribution of numerical data and skewness by displaying the data quartiles and averages.

Box plots are also known as box and whisker plot.

  • Box plots are used to compare visually differences among different samples or groups such medians, ranges, and outliers.

Therefore, the graph that would allow the comparison between the median number of teeth for mammals and reptiles easily is a Box Plot.

The original rectangle has a perimeter of 16
zaharov [31]

As we can see that the sides of the rectangle have been doubled

6.2 ft changed to 12.4 ft

Now when the sides have been doubled

the Perimeter will also be doubled

So the perimeter of new rectangle should be the double the perimeter of old rectangle

So perimeter of new rectangle = 2 (16 ) = 32 feet

Option C is correct
