Ne4ueva [31]

Answer:

The mural in David's drawing is 4 cm long.

Step-by-step explanation:

Given:

David made a scale drawing of a mural he is going to paint.

He used a scale of 1 cm=4ft.

If the actual mural will be 16 feet long.

Now, to find how long is the mural in David's drawing.

Let the length of mural in David's drawing be $x\ cm$ .

So, as given 1 cm = 4 ft.

1 cm is equivalent to 4 ft.

Thus, $x\ cm$ is equivalent to 16 feet.

Now, to get the length of mural in David's drawing by using the cross multiplication method:

$\frac{1}{4} =\frac{x}{16}$

By cross multiplication:

$16=4x$

Dividing both sides by 4 we get:

$4=x$

$x=4\ cm.$

Therefore, the mural in David's drawing is 4 cm long.

Francine has a picture whose length is 4/3 its width. She wants to enlarge the picture to have an area of 192 in2. What will the

nikklg [1K]

L=4W/3

A=LW, using L found above in this equation we have:

A=(4W)W/3

A=4W^2/3

3A=4W^2

3A/4=W^2

W=√(3A/4), we are told that A=192 in^2

W=√(3*192/4)

W=√144

W=12 in, since L=4W/3

L=4*12/3

L=16 in

So the length is 16 inches and the width is 12 inches.
