It would be 4.5. Hope this helps!
The plant grow 3.6 centimeter in 18 days and the student written it incorrectly as 1.44 days.
Division:
Division is the process of breaking a number up into equal parts, and finding out how many equal parts can be made. It is a reverse process of multiplication.
Given:
The ratio of growth for a plant is 0.2 centimeters per 0.5 day.
A student found the number of days for the plant to grow 3.6 centimeters to be 1.44 days.
Here we have to verify if the student is found the correct value or not.
For one day the plant grow 0.2 centimeter.
So, for 3.6 centimeter it will take
=> 3.6 / 0.2
=> 18
So, for 3.6 centimeter it will take 18 days.
So, here the student written it incorrectly as 1.44 days.

2. the ans is C because 3 sides in option C keep the same ratio as the 3 sides of triangle NOP: 7.5/5=1.5, 10.5/7=1.5 and 13.5/9=1.5
3. the ans is D
just see from the point Q(16,4), after the first dilation, the x-coordinate of Q=16*0.25=4, then by subtracting 4 from the x-coordinate of point T (i.e. -2-4=-6), then you can see only option D has the x-coordinate (x-6), so it shows that it is the ans
4. i dont know about this.. sorry :(
220,000
the thousands column is 5 or more therefore you round up
