The scale on a model railroad train set is 3.5 millimeters to 1 foot. If the length of a model car in the set is 150 millimeters

Vera_Pavlovna [14]

Answer:

The approximate length of the actual car is 43 feet.

Step-by-step explanation:

Given:

The scale on a model railroad train set is 3.5 millimeters to 1 foot. If the length of a model car in the set is 150 millimeters.

Now, to find the approximate length of the actual car.

Let the actual length of the car is $x.$

The length of a model car in the set is 150 millimeters.

As, given the scale on a model railroad train set is 3.5 millimeters to 1 foot.

So, 3.5 millimeters equivalent to 1 foot.

Thus, 150 millimeters to $x$ .

Now, to get the actual length of the car by using cross multiplication method:

$\frac{3.5}{1} =\frac{150}{x}$

By using cross multiplying we get:

$3.5x=150$

Dividing both sides by 3.5 we get:

$x=42.85\ feet.$

The approximate length of the actual car = 43 feet.

Therefore, the approximate length of the actual car is 43 feet.

Alex Ar [27]

Answer:

La base salarial de cada trabajador es de $ 425

Step-by-step explanation:

Aquí queremos calcular la base salarial de cada trabajador

Antes del incremento, sea la base salarial $ x

Entonces, sin el incremento, lo que ganarán los 3 es x + x + x = 3x

Con el incremento, cada uno ganará 3 (x + 50)

Esto es lo que es igual a 1425 Así; 3 (x + 50) = 1425

x + 50 = 1425/3

x + 50 = 475

x = 475 - 50

x = 425

Marizza181 [45]

A couple wanted to install a square mirror that has:

Area of the mirror = 500 square inches.

x = nearest tenth of an inch , length of wood needed

s = sides of square

Area = s2

500 (area) = s2 | √

x = √500

=> √ 5 x 100

=> √ 5 x √100

=> 10 √ 5

=> approximately 22.4

Since we’re looking for the nearest tenth of decimal place value, the answer is approximately 22.4
