Answer:

270

Step-by-step explanation:

Let V2=sqrt(2).

Note that V6=V3×V2

So, we have:

5×V6×V3×9×V2=

45×V3×V6×V2=

45×V3×(V2×V3)×V2

45×3×2=

45×6=

Answer:

270

Step-by-step explanation:

We can multiply all of the roots and all of the whole numbers together in this fashion:

9*5 *\sqrt{6*3*2}

this simplifies to:

45\sqrt{36}

45 * 6

= 270

The perimeters of square region S and rectangular region R are equal. If the sides of R are in the ratio 2 : 3, what is the rati
Ksivusya [100]
<h2>Answer:</h2>

The ratio of the area of region R to the area of region S is:

                    \dfrac{24}{25}

<h2>Step-by-step explanation:</h2>

The sides of R are in the ratio : 2:3

Let the length of R be: 2x

and the width of R be: 3x

i.e. The perimeter of R is given by:

Perimeter\ of\ R=2(2x+3x)

( Since, the perimeter of a rectangle with length L and breadth or width B is given by:

Perimeter=2(L+B) )

Hence, we get:

Perimeter\ of\ R=2(5x)

i.e.

Perimeter\ of\ R=10x

Also, let " s " denote the side of the square region.

We know that the perimeter of a square with side " s " is given by:

\text{Perimeter\ of\ square}=4s

Now, it is given that:

The perimeters of square region S and rectangular region R are equal.

i.e.

4s=10x\\\\i.e.\\\\s=\dfrac{10x}{4}\\\\s=\dfrac{5x}{2}

Now, we know that the area of a square is given by:

\text{Area\ of\ square}=s^2

and

\text{Area\ of\ Rectangle}=L\times B

Hence, we get:

\text{Area\ of\ square}=(\dfrac{5x}{2})^2=\dfrac{25x^2}{4}

and

\text{Area\ of\ Rectangle}=2x\times 3x

i.e.

\text{Area\ of\ Rectangle}=6x^2

Hence,

Ratio of the area of region R to the area of region S is:

=\dfrac{6x^2}{\dfrac{25x^2}{4}}\\\\=\dfrac{6x^2\times 4}{25x^2}\\\\=\dfrac{24}{25}

How can i show 5/8 is greater than 3/8
Serjik [45]
The first answer, using a number line, is a good answer.

I have two other ways:

Way #1:

5 stones is more than 3 stones.
5 gallons is greater than 3 gallons.
5 pounds is greater than 3 pounds.
5 puppies is greater than 3 puppies.
5 hamburgers is greater than 2 hamburgers.
5 schoolbuses is greater than 3 schoolbuses.

We look around us, and we see that 5 of anything
is always greater than 3 of the same thing.

There's no reason that should change if the 'things' are eighths.


Way #2:

-- Get 2 friends to help you.

-- Take one good-size veggie pizza or coconut cream pie.

-- Carefully cut it up in eight (8) equal pieces.
   Now each piece is 1/8 of the pie or the pizza.

-- Give 5 pieces (5/8) to the first friend.
   Give 3 pieces (3/8) to the other friend.

-- Ask them to get together and agree on who has more.
