A man is trying to calculate the shadow of a 24 flag pole. He uses similar triangles by comparing his own height 5 ft to the len
Pie

Answer:

The answer to your question is 12 ft

Step-by-step explanation:

Data

Height of the flag pole = 24

shadow of the flag pole = x

height of the man = 5 ft

shadow of the man = 2.5 ft

Process

1.- Use the Thales' theorem to solve this problem

shadow of the flag pole/height of the flag pole = shadow of the man/height

                                                                                                 of the man

- Substitution

                     x/24 = 2.5/5

- Solve for x

                    x = 2.5(24)/5

- Simplification

                    x = 60/5

-Result

                   x = 12 ft

What is the simplest form of
11111nata11111 [884]

Answer:

  1. 15 = -3c +12
  2. -3n +8 = -7
  3.  5z -40 = 10
  4. 3.4s -35 = 50

Step-by-step explanation:

Usually, you're asked to "simplify" an equation, meaning that you eliminate parentheses and combine like terms. Asking for "simplest form" suggests something different. The simplest form is the form that has the variable equal to a constant--the solution, in other words.

We suspect you want the <em>simplified form</em>, but since you asked for the <em>simplest form</em>, that is here, too.

__

1. 15=-3(c-1)+9

  15 = -3c +3 +9

  15 = -3c +12 . . . . . simplified form of the given equation

  -1 = c . . . . . . . . . . "simplest" form

__

2. 2(1.5n+4)-6n=-7

  3n +8 -6n = -7

  -3n +8 = -7 . . . . . . simplified form of the given equation

  n = 5 . . . . . . . . . . . "simplest" form

__

3. 2(z-20)+3z=10

  2z -40 +3z = 10

  5z -40 = 10 . . . . . . simplified form of the given equation

  z = 10 . . . . . . . . . . "simplest" form

__

4. 2/5s -2+3(s-11)=50

  0.4s -2 +3s -33 = 50

  3.4s -35 = 50 . . . . simplified form of the given equation

  s = 25 . . . . . . . . . . "simplest" form
