kipiarov [429]

Answer:

  11.2 ft

Step-by-step explanation:

Assuming the building meets the ground at right angles, the right triangle formed has side length 10 ft and hypotenuse 15 ft. Then the other side length (d) is given by the Pythagorean theorem as ...

  d² + 10² = 15²

  d² = 225 -100 = 125

  d = √125 = 5√5 ≈ 11.2 . . . feet

The bottom of the ladder is about 11.2 feet from the building

How many ways can an employer send 3 employees to a job fair if she has 11 employees?
algol13

We have to find the number of ways an employer send 3 employees to a job fair if she has 11 employees.

This is the problem from combination.

The formula for combination is given by

^nC_r= \frac{n!}{r!(n-r)!}

Here, n= 11, r= 3

Therefore, total number of ways is given by

^{11}C_3= \frac{11!}{3!(11-3)!}\\&#10;\\&#10;=\frac{11!}{3!8!}\\&#10;\\&#10;=\frac{8!\times 9 \times 10 \times 11}{3!8!}\\&#10;\\&#10;=\frac{9 \times 10 \times 11}{6}\\&#10;\\&#10;=165

A is the correct option.
