A tangent to a circle is a straight line which touches the circle at only one point. This point is called the point of tangency.

A cube has a side of 5 cm. it has a mass of 250 grams. the density of the cube is

Marrrta [24]

Density = mass/volume

volume cube = side^3 = 5^3 = 125 cm^3, don't forget units!

Density = 250 grams / 125 cm^3 = 2 g/cm^3, with all the units

What is the solution to the inequality below?

anastassius [24]

B because a negative squared is always a positive and it has to be a negativ number less than -3 is less than 9 and if it is greater than 3 than it would make it untrue.

Question:

aivan3 [116]

Answer:

part A) The scale factor of the sides (small to large) is 1/2

part B) Te ratio of the areas (small to large) is 1/4

part C) see the explanation

Step-by-step explanation:

Part A) Determine the scale factor of the sides (small to large).

we know that

The dilation is a non rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional

Let

z ----> the scale factor

$\frac{CB}{C'B'}=\frac{CD}{C'D'}=\frac{BD}{B'D'}$

The scale factor is equal to

$z=\frac{CB}{C'B'}$

substitute

$z=\frac{4}{8}$

simplify

$z=\frac{1}{2}$

Part B) What is the ratio of the areas (small to large)?

<em>Area of the small triangle</em>

$A=\frac{1}{2}(2)(4)=4\ units^2$

<em>Area of the large triangle</em>

$A=\frac{1}{2}(4)(8)=16\ units^2$

ratio of the areas (small to large)

$ratio=\frac{4}{16}=\frac{1}{4}$

Part C) Write a generalization about the ratio of the sides and the ratio of the areas of similar figures

In similar figures the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In similar figures the ratio of its areas is equal to the scale factor squared
