A map is made of a park. The scale from the park to the map is 36 mi to 6 cm. The length of great oaks trail is 4.5 cm on this m

mina [271]

Answer:

Salamander trail is longer than great oaks trail.

Step-by-step explanation:

We have the data from two different maps of the same park.

In the first map the length of great oaks trail is 4.5 cm

The scale from the park to the map is 36 mi to 6 cm ⇒

We can find the real length of great oaks trail writing the following equivalence :

$\frac{36mi}{6cm}=\frac{x}{4.5cm}$

Where x is the real length of great oaks trail ⇒

$x=\frac{(36mi).(4.5cm)}{6cm}=27mi$

We find that the real length of great oaks trail is 27 mi

In the second map the length of salamander trail is 3.5 cm

The scale from the park in the second map is 24 mi to 3 cm.

Again we can find the real length of salamander trail writing the equivalence :

$\frac{24mi}{3cm}=\frac{y}{3.5cm}$

Where y is the real length of salamander trail ⇒

$y=\frac{(24mi).(3.5cm)}{3cm}=28mi$

We find that the real length of salamander trail is 28 mi.

Therefore salamander trail is longer than great oaks trail.

What is the positive solution of |2x-6|=9?

Anarel [89]

Answer:

x = 15/2

Step-by-step explanation:

Remove the absolute value brackets.

2x-6=9

Add 6 to both sides.

2x = 15

Divide both sides by 2

x = 15/2

The answer is a fraction because 15/2 can't become a whole number.

Which ratio is equivalent to 1 : 5?

Travka [436]

Answer:

Infinite solutions.

Step-by-step explanation:

A ratio, which is essentially a fraction, can be written in an infinite number of ways and still have the same value..

As an example:

2/1 = 2

6/3 = 2

As long as both the top and bottom of a fraction are multiplied by the same value, the fraction will keep the same value.

So, any ratio that's a multiple of 1/5 is equivalent.
