How many square tiles of side 10cm each will be needed to tile a floor which is 300cm long and 150cm wide?
S_A_V [24]

Step 1

Find the area of one tile

we know that

the area of a square is

A=b^{2}

where b is the length side of the square

In this problem

b=10\ cm

Substitute

A=10^{2}=100\ cm^{2}

Step 2

Find the area of the floor

The area of a rectangle is equal to

A=LW

where

L is the length of the rectangle

h is the width of the rectangle

In this problem

L=300\ cm

W=150\ cm

Substitute

A=300*150=45,000\ cm^{2}

Step 3

Find the number of tiles needed

by proportion

\frac{1}{100} \frac{tile}{\ cm^{2}} =\frac{x}{45,000} \frac{tile}{\ cm^{2}} \\ \\x=45,000/100 \\ \\x=450 \ tiles

therefore

<u>the answer is</u>

450 \ tiles

Which is the rationalized form of the expression sqrtx/sqrtx+sqrt7
ArbitrLikvidat [17]

Answer:

(x - √7*√x) / (x - 7)

Step-by-step explanation:

I suppose your expression is √x / (√x + √7)

(√x * (√x - √7)) / ((√x + √7) * √x - √7)) = (√x * √x - √7 * √x) / (x - 7)

= (x - √7*√x) / (x - 7)

According to the information provided in the fragment, edifying universality can be understood as a term that the king includes in his speech. In general, these terms can be explained by referring to the author's explanation in Passage 1.

<h3>What is the statement the author uses to explain the term?</h3>

The statement the author uses to explain the term the King includes in his speech is:

  • "The edifying universality of those four words who hasn't dreamed, and who cannot identify with people whose dreams of a better world are punished with violence helps to explain their durability."

According to the above, lines 76-79 are referring to how the author of Passage 1 explains the King's point of view in his speech.
