The distance on a map is 4.5 cm. The scale of the map is 1 : 1000. What is the actual distance?. Single choice.

Answers

Answer:

Actual distance is 4500 cm (45 m).

Step-by-step explanation:

A scale is a representative fraction that can be used to either increase or decrease proportionally the dimension of a given object.

scale = [tex]\frac{distance on map}{actual distance}[/tex]

It is in the form of a ratio.

From the question, Distance on map = 4.5 cm,

scale = 1 : 1000

= [tex]\frac{1}{1000}[/tex]

scale = [tex]\frac{distance on map}{actual distance}[/tex]

Let the actual distance be represented by d.

So that,

[tex]\frac{1}{1000}[/tex] = [tex]\frac{4.5}{d}[/tex]

⇒ d = 4.5 x 1000

= 4500

d = 4500

The actual distance is 4500 cm (45 m).

Answers

Answer: 25x^2 + 40x + 16

Explanation: Apply perfect square formula
(5x)^2 + 2 * 5x * 4 + 4^2
Simplify

The multiplication of the given equation i.e. [tex](5x + 4)^2[/tex] should be considered as the [tex]25x^2 + 40x + 16[/tex].

Calculation of the equation:

Since the given equation is [tex](5x + 4)^2[/tex]

We have to break this equation

So, it can be like

[tex](5x)^2 + 2 \times 5x \times 4 + 4^2[/tex]

[tex]25x^2 + 40x + 16[/tex]

Hence, we can conclude that The multiplication of the given equation i.e. [tex](5x + 4)^2[/tex] should be considered as the [tex]25x^2 + 40x + 16[/tex].
