$\frac{9~divided~by~3}{12~divided~by~3} = \frac{3}{4}$

$\frac{3}{4}$ is a simplified form for $\frac{9}{12}$

Answer:

The slopes of line segments AC and AD are same or constant i.e $\frac{1}{3}$

Step-by-step explanation:

We need to find slopes of AC and AD and tell if they are same or not.

The formula used to calculate slope is: $Slope=\frac{y_2-y_1}{x_2-x_1}$

Finding slope of AC

We have A=(3,2) and C=(0,1)

Finding slope using formula:

We have $x_1=3, y_1=2, x_2=0,y_2=1$

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{1-2}{0-3}\\Slope=\frac{-1}{-3}\\Slope=\frac{1}{3}$

So, Slope of AC is $\frac{1}{3}$

Finding slope of AD

We have A=(3,2) and C=(9,4)

Finding slope using formula:

We have $x_1=3, y_1=2, x_2=9,y_2=4$

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{4-2}{9-3}\\Slope=\frac{2}{6}\\Slope=\frac{1}{3}$

So, Slope of AD is $\frac{1}{3}$

So, the slopes of line segments AC and AD are same or constant i.e $\frac{1}{3}$

50 POINTS: Please help thank you so much!! (Image attached) The polygons are similar. Find the values of the variables.

Step-by-step explanation:

9 + y^2 = 49

y^2 = 40

y = √40 = 2√10

4.5/3 = 2√10/5x

22.5x = (3) 2√10

22.5x = 6√10

x = 6√10/22.5 = 3√10/11.5

Step-by-step explanation:

subtract-13 from -13 get zero

then, subtract 13 from 77 =64

then do divide 15 from 15

then divide 15 from 64 = 4.26 repeat

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.
