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,

Hence, the actual height of train = 4.896 meters.
Answer:
-32
Step-by-step explanation:
f(x) = 2x + 6
f(-19) = 2*(-19) + 6
= -38 + 6
= -32
The answer is 25.
4 green balloons : 5 purple balloons
20 green balloons : 25 purple balloons.
In order to get to 20 from 4 u need to multiply by 5. Do that to each side and get 25
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.
