255 hours / 85 hours = 3.
This means that the bacteria will double in size 3 times.
900,000 × 2 = 1,800,000
1,800,000 × 2 = 3,600,000
3,600,000 × 2 = 7,200,000
After 255 hours, the colony of bacteria will be 7,200,000
Answer:
True
Step-by-step explanation:
Any point on the x- axis has a y- coordinate of zero, hence
(2, 0) lies on the x- axis
Answer:
The required equation is
.
Step-by-step explanation:
Consider the provided information.
The Initial value of poster = $ 18
After 1 year amount of increase = $ 20.70
With the rate of 15% = 0.15
Let future value is y and the number of years be x.

Now verify this by substituting x=1 in above equation.

Which is true.
Hence, the required equation is
.
Answer: 10
use (PEMDAS)
P parentheses ()
E exponents
M multiplication • , () , x
D division
A addition +
S subtraction -
Explanation:
There are no parentheses.
There are exponents.
The multiplication is the exponents.
There is division.
There is addition and subtraction.
-how to solve-
First, do 2 to the second power and get 4.
Next, do 12-2+4 divided by 8.
Next do multiplication: there’s no more.
Next do division: you can’t do 4 divided by 8 so instead, do 12-2 = 10 plus 8.
Hope this helps!
