AlladinOne [14]

Answer:

4) x^10

Step-by-step explanation:

1) If two numbers have the same base (i.e. x^3 and x^4) and you are multiplying them you just add the exponents. Therefore x^3*x^4 would be x^(3+4) which equals x^7.

2) When dividing similar bases you have to subtract the exponents. If we have x^18÷x^8 that is equivalent to x^(18-8) which gives us x^10.

3) If we have (x^3)^3 we will need to multiply the exponents. Therefore (x^3)^3 is equivalent to x^(3*3) which gives us x^9.

4) (x^2*x^4)^4÷x^8

First do what's in the parentheses,

(x^2*x^4) = x^6

Next do the exponents,

(x^6)^3 = x^18

Lastly the division,

x^18÷x^8 = x^10

x^10 is our answer.

Roberto tiene 20 balones entre azules y rojos el tiene mas balones rojo que azules y los guarda en cuatro bolsas que contienen l
Anuta_ua [19.1K]

Se pueden concluir dos posibilidades para cada bolsa y toda la colección:

  1. 4 balones rojos y un balón azul, lo cual lleva a 16 balones rojos y 4 balones azules.
  2. 3 balones rojos y dos balones azules, lo cual lleva a 12 balones rojos y 8 balones azules.

<h3>¿Cuántos balones rojos tiene Roberto en las cuatro bolsas?</h3>

En este problema conocemos que Roberto tiene 20 balones entre azules y rojos y que existen más balones rojos que azules. Puesto que los balones son objetos que pueden contarse, los datos a buscar deben ser números enteros y positivos y que están distribuidos equitativamente en cuatro bolsas. Entonces las cantidades de balones por bolsa son:

x = 20 / 4

x = 5

Existen 5 balones por bolsa y bajo la consideración de que existen balones azules, que cada bolsa tienen la misma proporción de balones rojos a azules y que los balones rojos son más que los balones azules, se pueden concluir dos posibilidades para cada bolsa:

  1. 4 balones rojos y un balón azul, lo cual lleva a 16 balones rojos y 4 balones azules.
  2. 3 balones rojos y dos balones azules, lo cual lleva a 12 balones rojos y 8 balones azules.

The perimeter of a parallelogram is 72 meters. The length of the parallelogram is 4 meters less than its width. What is the leng
Alexeev081 [22]
A parallelogram has 4 sides.
So, we divide 72, the meters of the parallelogram. = 18
Now, the length is 4 more, so we add. 18+4=22
The length is 22.

Now, both lengths are 22, so double is 44; subtract 44 from 72. 72-44=28
In conclusion, we divided 28 by 2 to get the width of both sides.28/2=14
The width is 14.

Tresset [83]

Answer:

594 rpm

Step-by-step explanation:

Two gears will have the same linear speed, so:

v₁ = v₂

ω₁ r₁ = ω₂ r₂

(316 rpm) (79) = ω (42)

ω ≈ 594 rpm
