An amoeba divides to form two amoebas after one hour. One hour later, each of the two amoebas divides to form two more. Every hour, each amoeba divides to form two more.
1. How many amoebas are there after 1 hour?
2. How many amoebas are there after 2 hours?
3. Write an expression for the number of amoebas after 6 hours.

Step-by-step explanation:

Given that the number of amoeba is 1

in 1 hour it divides to form 2

1 hour later (2 hours): 1 amoeba(forms 2), 1 amoeba(forms 2)= 4  

1 hour again(3 hours):   1=2,1=2,1=2,1=2 hence a total of 8 after 3 hours

Question and answers

1. How many amoebas are there after 1 hour

=2 amoebas

2. How many amoebas are there after 2 hours

=4 amoebas

3. Write an expression for the number of amoebas after 6 hours.

let the number of amoeba be y, and the time be n

so in 6 hours n= 6

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
