Answer:
6 minutes
Step-by-step explanation:
'a' in the formula represents altitude in feet. You are told the altitude is 21000 feet, so put that into the formula:
21000 = 3400t +600
You can solve this for t:
20400 = 3400t . . . . . subtract 600 from both sides
6 = t . . . . . . . . . . . . . . . divide both sides by 3400
The problem statement tells you that t represents minutes after lift off, so this solution means the altitude is 21000 feet 6 minutes after lift off.
The question is asking for the number of minutes after lift off that the plane reaches an altitude of 21000 feet, so this answers the question directly:
The plane is at an altitude of 21000 feet 6 minutes after lift off.

3/5 and 1/2 can be 6/10 and 5/10. then 0.1/2 is 0.05. for the other part, just plug 0.72 x 1.6 into a calculator.
Answer:
A. 1/3
Step-by-step explanation:
Dado que:
una manzana se corta en 12 partes y se comen ocho partes.
La fracción de manzanas consumidas = 8/12
= 2/3
La fracción de manzanas que quedan = valor original de la manzana que se corta - la fracción de la manzana que se come
La fracción de manzanas que quedan 
La fracción de manzanas que quedan 
La fracción de manzanas que quedan 
A la fracción más baja; obtenemos = 1/3
The dependent value is determine by the value of the independent value. in other words, the dependent value is what you get when you take the independent value and substitute it in the original equation or situation. The relationship is multiplicative because you must first multiply the independent value in the equation where the x is before you can add or subtract to get your answer.<span />
