ANSWER

- 7 \sqrt{6}

EXPLANATION

The given radical expression is

3 \sqrt{6}  - 10 \sqrt{2}  \times  \sqrt{3}

Recall and use

\sqrt{a}  \times  \sqrt{b}  =  \sqrt{ab}

to obtain;

3 \sqrt{6}  -10 \sqrt{2 \times 3}

Simplify the second radicand.

3 \sqrt{6}  - 10 \sqrt{6}

We have two like surds so we can simplify to obtain;

- 7 \sqrt{6}

Answer:

Viruses are 2 times of the bacteria.

Step-by-step explanation:

Given:

Number of viruses = 2\times 10^9

Number of bacteria = 1\times 10^9

We have to found how many times viruses are greater than the bacteria.

To find how many times,we can divide both the numbers to compare its values.

Lets

Numerator = Number of viruses

Denominator = Number of bacteria

Dividing both we have,

⇒ \frac{2\times 10^9}{1\times 10^9}

⇒ 2\times 10^(^9^-^9) ...\frac{ab^x}{cb^y}=\frac{ab^x^-^y}{c}

⇒ 2\times 10^0       ...a^0=1

⇒ 2

So the viruses are 2 times of the bacteria.

A Jésica le piden hacer dos esculturas triangulares idénticas. En la primera le solicitan que su perímetro sea de 80 centímetros
grigory [225]

La esculturas triangulares tendrán las siguientes medidas 16.66 cm, 40 cm y 23.32 cm.

<h3>¿Qué e el perímetro?</h3>

Es la suma total de los lados del triángulo, en este caso el perímetro total es de 80.

<h3>¿Cómo calcular las dimensiones del triángulo?</h3>

Se pueden calcular usando el total y la información sobre cada lado:

  • x+4 + 3x+2 + 2x-2 = 80
  • 6x + 4 = 80
  • 6x = 80 - 4
  • 6x = 76
  • x = 76/ 6
  • x = 12.66

Finalmente calcule cada lado:

  • A. x+4 = 12.66 + 4 = 16.66
  • B. 3x + 2 = 3 x 12.66 + 2 = 39.98 o 40
  • C. 2x - 2 = 23.32

Write a number with one decimal place,that is bigger than 6 4/5 but smaller than 7 how can I solve this
statuscvo [17]
Hello!

The easiest way to solve this would be to convert 6 4/5 to a decimal. We know that to convert a fraction to a decimal, we must divide the numerator by the denominator. 

4 / 5 = 0.8 

0.8 + 6 = 6.8

So, 6 4/5 is 6.8 as a decimal. 

See how it's easier now that we've converted the mixed number to a decimal? 

There could be many numbers between 6.8 and 7. Some examples are: 

6.81, 6.82, 6.83, 6.9, etc.
