Answer:

the Ratio between the small and big triangles is that of b. $\frac{1}{3}$

Step-by-step explanation:

We can solve this ratio problem by using the Rate of Change formula as shown below,

$\frac{y2-y1}{x2-x1}$

In this situation y would be the smaller triangle and x would be the larger triangle. Since all the values are given to use we can just plug those values in and solve for the rate of change / ratio.

$\frac{4-3}{12-9} = \frac{1}{3}$

So the rate of change or ratio between the small and big triangles is that of $\frac{1}{3}$

3² • 9³ = [ ] solve

RideAnS [48]

Answer:

3⁸ or 6561

Step-by-step explanation:

First, let's look at PEMDAS - Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

There are no parentheses, so let's solve the exponents.

3² • 9³

3² = 9

9³ = 729

Your expression is:

9 • 729

Now let's multiply.

= 6561

This number can also be expressed with exponents.

Since 9 = 3², 9³ = 3²⁽³⁾

Now your expression is:

3² • 3²⁽³⁾

First, solve the exponents by multiplying.

3² • 3⁶

When you multiply two expressions with exponents that have the same base (3), you add the exponents.

3² • 3⁶ = 3⁽²⁺⁶⁾ = 3⁸

3⁸ also equals 6561.

Your answer is 3⁸ or 6561.

Hope this helps!

Suponha que uma variável assume os valores: 11 – 8 – 7 – a – 16 – 10 Determine a de modo que a média aritmética seja igual 11.

Elenna [48]

Answer:

a = 14

Step-by-step explanation:

The mean is the sum of the values divided by the number of values.

$\begin{array}{rcl}\text{Mean}&= &\dfrac{11 + 8 + 7 + a + 16 + 10}{6}\\\\\dfrac{52 + a}{6}& = & 11\\52 + a & = & 66\\a & = & 66 - 52\\& = & \mathbf{14}\\\end{array}$

Which transformation(s) can be used to map one triangle onto the other? select two options. reflection only translation only dil

exis [7]

Transformation which can be used for mapping of one triangle to another are;

Only translation
Rotation then dilation.

What does mapping mean in geometry?

Any method that is outlined for assigning a specific object from one (or the same) set to each object in another is known as mapping.
Any set, including all whole integers, all the points on a line, or all the objects inside a circle, can be mapped.

We need to map one triangle to another ;

Hence, for mapping of one triangle to another,

The transformation which can be used from the given options are;

Only translation
Rotation then dilation
