Help!!! I just need Help on number 6 please!!!!!!!! ASAP!!!

PtichkaEL [24]

Answer:

$3$

Step-by-step explanation:

$\sqrt{12} =3.46$ (2 decimal places)

If you want to arrange the tiles into a square, you will need 3.46 in each row/column.

This is physically impossible, hence you round it down to 3.

(If you round it up, you won't have enough tiles since $4*4=16$ )

Thus, the square area will be $3*3=9$

Tiles left: $12-9=3$

The speed, v, of a wave is inversely proportional to the square root of the

yKpoI14uk [10]

Answer:

v = 120

Step-by-step explanation:

If v is inversely proportional to square root of d, then we can write

$v \sqrt{d}$ = k

If v = 30 and d = 400, then

30( $\sqrt{400}$ ) = k

k = 30(20) = 600

Now $v \sqrt{d}$ = 600

If d = 25, then v $\sqrt{25}$ = 600

5v = 600

v = 120
