given h = 600 - 16t ( add 16t to both sides )
16t + h = 600 ( subtract h from both sides )
16t = 600 - h ( divide both sides by 16 )
t = 
when h = 400
t =
=
= 12.5 seconds
Answer:
6 students at the preschool of four years old attended the full day program.
Step-by-step explanation:
Given:
Number of four years old students = 16
fraction of four years old students attended full day program = 
We need to find the number of four years old students attended the full day program.
Solution:
Now we can say that;
number of four years old students attended the full day program is equal to fraction of four years old students attended full day program multiplied by Number of four years old students.
framing in equation form we get;
number of four years old students attended the full day program = 
Hence 6 students at the preschool of four years old attended the full day program.
11a.
12a-1a=11a is same thing as 12a-a
700,000+2,000+1, should be your answer.
