Solve four square root of six plus eight square root of four and explain whether the answer is rational or irrational.

Inga [223]

Answer:

$4\sqrt{6}+16$

Step-by-step explanation:

Given the expression: $4\sqrt{6}+8\sqrt{4}$

$\sqrt{4}=2\\$Therefore, \\4\sqrt{6}+8\sqrt{4} =4\sqrt{6}+8*2\\ =16+4\sqrt{6}$

We can re-write the answer as:

$4\sqrt{6}+16$

The answer is irrational because the sum of a rational number and irrational number is an irrational number.

<u>The correct option is B.</u>

María regala a su padre un best seller por su cumpleaños. Elige la encuadernación de tapas duras que tiene forma de prisma recta

iris [78.8K]

Answer:

<h2>María used only 792 square centimeters to cover the best seller.</h2>

Step-by-step explanation:

The volume of the best seller is about a rectangular prism, which is

$V= w \times l \times h$

Where $w$ is width, $l$ is length and $h$ is height.

In this case, we have

$w=12 \ cm\\l= 18 \ cm\\h= 6 \ cm$

Replacing values in the formula, we have

$V=12cm \times 18cm \times 6cm=1,296cm^{3}$

Now, according to the problem, 10% of paper covers the book, that means we need to find the suface area and then find the 90% of the paper missing. The formula for surface area is

$S=2wl+2lh+2hw$

Replacing values, we have

$S=2(12)(18)+2(18)(6)+2(6)(12)=432+216+144=792cm^{2}$

If 792 square centimeters is 10% of the total paper, then

$x=100\%\frac{792cm^{2} }{10\%} =7,920cm^{2}$

Therefore, there is 7,920 square centimeters of papers, but María used only 792 square centimeters to cover the best seller.

Which is larger 18% or 2/11?

Cloud [144]

2/11 is larger.

Explanation :

Because if you cover it to decimal,

18% will be 0,18 only

but

2/11 will be 0,188888-

which means it can be 0,19 if 2 decimal behind coma and of course 0,19 is larger dan 0,18

try devide 2 with 11 .
