One positive number is 5 times another number. The difference between the two numbers is 200, find the numbers.
Ilya [14]
X = 5y, where x > 0 and y > 0;
x - y = 200 => 5y - y = 200 => 4y = 200 => y = 200/4 => y = 50 => x = 250.

The circle will be enlarged by a scale factor of 4.
sertanlavr [38]

Answer:

The area of the new circle is  144\pi \ in^2

Step-by-step explanation:

Given:

radius of the circle = 3 in.

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 the enlarged circle

y-----> the area of the original circle

So;

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

In this problem we have

z=4 ----> the scale factor

The area of the original circle is equal to

y = \pi r^2= \pi (3)^2= 9\pi \ in^2

Now substituting value of y and solve for x we get;

4^2=\frac{x}{9\pi}\\ \\x= 16\times9\pi= 144\pi \ in^2

Hence Area of the new Circle is 144\pi \ in^2

Also The area of the enlarged circle is 16 times the area of the original circle.
