Abuilding is 2 ft from an 8-ft fence that surrounds the property. a worker wants to wash a window in the building 12 ft from the ground. he plans to place a ladder over the fence so it rests against the building. (see the figure.) he decides he should place the ladder 8 ft from the fence for stability. to the nearest tenth of a foot, how long a ladder will he need?

length of the ladder should be 16 feet.

Step-by-step explanation:

In the figure attached,

B is the window at 12 feet from the ground.

Building AB is 2 feet away from the fence DE.

Ladder AC is placed 8 feet away from the fence at a point C.

We apply Pythagoras theorem to calculate the length of the ladder.

AC² = AB² + BC²

AC =

     =

     =

     = 15.62

     ≈ 16 feet

Therefore, length of the ladder should be 16 feet.

hey there!

12 is twice as much as 6 because 6 goes into 12 2 times.

since the rabbit is twice as tall, we should multiply the weight of the first rabbit, 0.25, by 2.

0.25 x 2 = 0.5

therefore, the 12 inch chocolate rabbit weighs 0.5 lb, or half a pound.

hope this !
