alekssr [168]

Answer: The actual height of train = 4.896 meters.

Step-by-step explanation:

Since we have given that

Lina has a scale model of a modern train

Model is created at a scale is given by

1:48

Height of the model train = 102 millimeters

We need to find the actual height of the train.

Since there is direct variation between model and actual height of the train.

According to question,

\frac{1}{48}=\frac{102}{x}\\\\x=102\times 48\\\\x=4896\ millimeters\\\\x=4.896\ m

Hence, the actual height of train = 4.896 meters.

A rectangle has twice the area of a square. the rectangle is 18 inch by 4 inch . what is the perimeter of the square
Westkost [7]
Rectangle:

A = BH
   = (18)(4)
   = 72

Finding area of square:

72 = 2x
/2     /2
36 = x

Finding perimeter of square using area:

P = √a * 4
   = √36 * 4
   = 6 * 4
   = 24

Therefore the perimeter of the square is 24 inches. I am not sure so sorry for any mistakes.
