Make our unknown equal to x, in this case his current age.

In 20 years he will be three times as old as he is now, in other words:

x + 20 = 3x

Now solve the equation:

20 = 3x - x
20 = 2x
10 = x

The sun shines at a 30° angle to the ground. To the nearest inch, how long is the shadow cast by a 72-in, tall fence post?
Anestetic [448]

The length of the shadow is 124.7 in

<u>Explanation:</u>

Angle of sun to the ground, θ = 30°

Height of the fence, h = 72 in

Length of the shadow, l = ?

We know,

tan θ = (Perpendicular)/(Base)  

So,

tan 30° = \frac{72}{l}

\frac{1}{\sqrt{3} } = \frac{72}{l} \\\\l = 72\sqrt{3} \\\\l = 124.7  

Therefore, the length of the shadow is 124.7 in

The given expression evaluates to -19.

<h3>What is a expression? What is a mathematical equation? What do you mean by domain and range of a function?</h3>
  • A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
  • A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
  • For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which [y] exists.

We have the following expression -

- 6 - 13

The given expression evaluates to -

x = - 6 - 13

x = - 19

Therefore, the given expression evaluates to -19.
