Answer:
21.1 inches
Step-by-step explanation:
The gecko is 3.5 inches to start with.
If it grows at a rate of 1.2 inches per month for the first 12 months, after 12 months the gecko will be 14.4 inches larger. (Because 12 times 1.2 is 14.4)
So, after 12 months the gecko will be 17.9 inches.
Since the gecko grows at 0.4 inches per month for the next 16 months, and the gecko has grown for 20 months, all we need to do is subtract 12 from 20 (since we already calculated how long it will be after 12 months) and multiply that by 0.4.
Since 20 - 12 is 8, we just multiply 8 by 0.4 to get 3.2. We now add 3.2 to 17.9 to get 21.1 inches.
Hope this helps!

Answer:
The model swing should be <u>2.75 cm</u> high.
Step-by-step explanation:
Given:
A 168-cm tall person is 2 cm in Ming’s model.
If the actual swing is 231 cm high.
Now, to find how high should his model swing be.
Let the model swing be 
So, 168 cm tall person is equivalent to 2 cm.
Thus, 231 cm actual swing is equivalent to 
model swing.
Now, we get the height of the swing in the model by using cross multiplication method:
<em>By cross multiplication:</em>
⇒ 
<em>Dividing both sides by 168 we get:</em>
⇒ 
Therefore, the model swing should be 2.75 cm high.
