likoan [24]

Answer:

The scale of the drawing is $\frac{1}{9}\ \frac{in}{ft}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of an house on a scale drawing in square inches

y ---> the actual area of the house in square feet

$z^2=\frac{x}{y}$

we have

$x=25\ in^2$

$y=2,025\ ft^2$

substitute

$z^2=\frac{25}{2,025}$

simplify

$z^2=\frac{1}{81}$

square root both sides

$z=\frac{1}{9}\ \frac{in}{ft}$

therefore

The scale of the drawing is $\frac{1}{9}\ \frac{in}{ft}$

Anon25 [30]

Answer:

Step-by-step explanation:

Because it is 1/8 it is much easier.

8 times 5 = 40

So you know that 1/8 was timesed by 40 to get 5. This means you can times x by 40 to get the cups of popcorn the kernels would produce. That means 1 times 40 equals 40. Making the cups of popcorn the kernels would produce is 40.
