Answer:

102.585

Step-by-step explanation:

first find the area of the hat-like shape which is th ebottom rectangle plus the top square, 3 x 10 + 3 x 3. solve it and get 39. next yo ufind the area of the circle (the formula is πr^2) 4.5^2 x 3.14(because it says use it instead of π) and solve to get 63.585. add these two shapes and you get 39+ 63.585 and it is 102.585

8) Use the slope formula to find the slope between<br> the points: (-1,2) and (3,- 3)<br> m =

nikdorinn [45]

Answer:

-5/4

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

= ( -3 -2)/( 3 - -1)

= ( -3-2 ) /( 3+1)

= -5/4

Dilate a triangle with vertices (0,0), (0,2) and (2,0) using the scale factor k=3. What is the value of the ratio (new to origin

seropon [69]

Answer:

Part a) The ratio of the perimeters is $3$

Part b) The ratio of the areas is $9$

Step-by-step explanation:

Part A) What is the value of the ratio (new to original) of the perimeters?

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

Let

z-----> the scale factor

x-----> the perimeter of the new triangle

y-----> the perimeter of the original triangle

$z=\frac{x}{y}$

we have

$z=3$

substitute

$\frac{x}{y}=3$

Part B) What is the value of the ratio (new to original) of the areas?

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z-----> the scale factor

x-----> the area of the new triangle

y-----> the area of the original triangle

$z^{2}=\frac{x}{y}$

we have

$z=3$

substitute

$\frac{x}{y}=3^{2}$

$\frac{x}{y}=9}$
