The floor of a room is being covered with tile. An area one half

tangare [24]

Answer:

Only the floor area $\frac{3}{8}$ has been covered

Step-by-step explanation:

Assuming that the floor of the room is rectangular, then its area is equal to the product of its length times its width.

$A = lw$

Let's now call A 'the area that was covered with tiles.

We know that half the length was covered, then:

$l' = \frac{1}{2}l$

$w' = \frac{3}{4}w$

So:

$A' = \frac{1}{2}l(\frac{3}{4}w)$

$A' = \frac{3}{8}lw$

Finally:

$A' = \frac{3}{8}A$

At the farmers market two pounds of peaches cost 4.20 how much would five pounds cost show work

Marizza181 [45]

Hey!

You can make a proportion:

$\frac{2}{\$ 4.20} = \frac{5}{x}$

Cross multiply

$\$ 4.20 \times 5 = \$ 21$

Divide by 2

$\$ 21 \div 2 = \$ 10.5$

<em>5 pounds would cost $10.50</em>

Good luck and hope this helps! :)
