The scale factor = 3.00

The scale factor of a circle to another is the ratio of their radii

Radius of the first circle = 9 in

Diameter of the second circle = 6 in

Radius = Diameter / 2

Radius of the second circle = 6 / 2

Radius of the second circle = 3 in

Scale factor = (Radius of the first circle) / (Radius of the second circle)

Scale factor = 9/3

Scale factor = 3.00 (2 decimal places)

Suppose the foot of a 12-foot ladder was placed 4 feet from a building how high up on the building would the top of the ladder r
NikAS [45]

Use the pythagorean theorem.

The foot of the ladder is 4 feet away from the building (leg 1)

The height of the building is leg 2

The ladder, which would be at an angle, is 12 feet. So our hypotenuse would be 12. The equation for this would be a²+4²=12²

We can then begin to solve

a² + 16 = 144  

a² = 128

a=11.31

So, our answer is: The top of the ladder reaches the building at 11.31 feet up

Solve for x if AB = 5x and BC = 3x + 24.
NikAS [45]

The value of x according to the given task is; 12.

<h3>What is the value of x?</h3>

It follows from the task content that the value of x is to be determined.

Since, lines AB and BC are both tangent to the circle and they both share a point of intersection; it follows that;

5x = 3x +24

  • collect like terms

2x = 24

  • divide both sides by 2

x = 24/2

x = 12.
