Answer:

\displaystyle\rm  15000

Step-by-step explanation:

we given the area of rectangular floor and tile we want to find the number of tiles needed to tile the floor

notice that the area of the rectangular floor is in meter and the tile in cm so we need to convert cm to meter in order to figure out the number of tiles needed to tile the floor

therefore,

\rm 1m \implies 100 c m\\   \rm{1m}^{2}  \implies10000 {cm}^{2}

remember that,

\displaystyle\rm \: N _{ \rm tile} =  \frac{A _{ \rm floor} }{A _{ \rm tile}  }

Thus substitute:

\displaystyle\rm \: N _{ \rm tile} =  \frac{360 \times 10000 {cm}^{2}  }{ {240cm}^{2}   }

simplify which yields:

\displaystyle\rm \: N _{ \rm tile} =  15000

hence,

15000 of tiles needed to tile the floor

Answer:

1500

Step-by-step explanation:

The area of the regtangular floor is 360m². The floor is going to be retired with tiles having area of 240cm² . We need to find the number of times . Therefore ,

\implies 360m^2 = 360 \times 10^4 \ cm^2

And , the number of tiles required will be ,

\implies n =\dfrac{Area \ of \ floor}{Area \ of \ a \ tile }\\\\\implies n =\dfrac{ 360 \times 10^4 \ cm^2}{240 cm^2} \\\\\implies \underline{\underline{ n = 1,500 }}

Hence the required answer is 1500 .

use Pythagorean Theorem to satisfy...a^2 + b^2 = c^2

200^2 + b^2 = 300^2
b^2 = 300^2 - 200^2
b^2 = 50000  (get square root of each)
b = 223.606  (rounded to the nearest tenth.... = 223.6

denis-greek [22]

Answer:

s = -3

Step-by-step explanation:

8s + 9 = 7s + 6

Subtract 7s from each side

8s-7s + 9 = 7s-7s + 6

s+9 = 6

Subtract 9 from each side

s + 9-9 =   6-9

s = -3
