Answer:
Four hundredths
In standard form - 
Step-by-step explanation:
Given : The green darner is one of the largest dragonflies.
It weighs about four hundredths of an ounce.
To write : Four hundredths in standard form.
Solution :
Standard form is when we write a larger number in a smaller way.
For example : 
So, according to question
Largest dragonflies weighs about four hundredths of an ounce.
Four hundredths means 0.04
In standard form - 
If 3mile=28 min
x mile=42 min
cross multiply
x=3/28
therefore if 3/28=1 min
then x mile= 42 min
cross multiply
42 x 3/28 =21 x 3/14
=3 x 3/1
=9
The answer is 9 miles
If we let x as the number of years of service in the company and f(x) as the increase in the wage, the step wise function that describes the scenario is
f(x) = { 0.5, x < 3
{ 1.0, 3 ≤ x < 6
{ 1.5, 6 ≤ x < 9
{ 2.0, 9 ≤ x < 12
The point (2, 12) represents the wage increase of x < 12
