Answer: Its 15

Step-by-step explanation:

All you had to do was add 9 + 6 because the 3 to triangle by eah are worth 3 and so are the bottom ones, to that makes 9 + 6 so just add and get 15 if that makes sence, i had the same question.

Answer:

There needs to be more information. We at least need to know what one of the side measurements for each triangle are. Only then can we give you the answer.

The sum of 2 composite numbers is never a prime number. Explain your answer.

Natasha2012 [34]

Answer:

Step-by-step explanation:

Composite numbers are positive numbers that have factors, This means that they are divisible by numbers other than 1 and itself provided that number is a factor of the composite number. They possess at the bearest minimum level, a divisor other than 1 and itself. They are a natural number that is expressible as the product of two(or more) numbers other than 1 and itself.

For example:

4 is a composite number because its factors are 1, 2 and 4 which have another divisor apart from 1 and itself (4). That divisor is 2.

We all know that prime numbers are numbers that can be only be divided by 1 and itself.

Therefore, the sum of two composite number, for example:

4 + 6 = 10, We can now see that 10 is never a prime number.

Answer:

(5/6)

Step-by-step explanation:

Bc (2/3)=0.666666666667....

(2/15)*(4/5) doesn't make 0.666666666667

(4/5)*(5/6)= 0.666666666667

The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function C equals 34.95 yo

ASHA 777 [7]

Answer:

8 ≤ u ≤ 12

Step-by-step explanation:

Given:

C = 34.95u +6.25

Where,

u = number of uniforms

what is the domain you of the function for this situation

The number of uniforms depend on the number of players

If there are at least 8 players but not more than 12 players on the volleyball team.

u ≥ 8

u ≤ 12

The domain of the function is

8 ≤ u ≤ 12

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)?

Area of the small triangle

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

Area of the large triangle

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

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

MatroZZZ [7]

Answer:

General Formulas and Concepts:

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

Step 1: Define function

f(x) = 8x + 4

Step 2: Prep

Rewrite: y = 8x + 4
Swap x and y: x = 8y + 4

Step 3: Find Inverse (Solve for y)

Subtract 4 on both sides: x - 4 = 8y
Divide both sides by 8: (x - 4)/8 = y
Rewrite: y = (x - 4)/8
Rewrite: f⁻¹(x) = (x - 4)/8
