We have been given that a particular type of cell increases by 75% in number every hour. We are asked to find the number of cells present at the end of 12 hours if there are initially 4 of these cells.
We will use exponential growth formula to solve our given problem.
, where,
y = Final amount,
a = Initial amount,
r = Growth rate in decimal form,
x = Time.
Upon substituting initial value 
and 
in above formula, we will get:
Therefore, there will be approximately 3300 cells at the end of 12 hours.
Answer:
3,7,9
Step-by-step explanation:
If 40% are boy and there are 12 boys
40% of girls would be 12 and another 20% is 6 so
You add 12+12+6=30 students total
Answer:
the answer is "AB"
Step-by-step explanation:
I plugged it into photomath
C. 9 square roots of 2
To answer this question, it's super important that you understand the ratio of sides for special triangles. This triangle in particular, a 45-45-90 triangle, has a ratio between the legs and hypotenuse of 1:1:
Since we are given the value of the hypotenuse, we know that the value of the two sides multiplied by 
will be 18. Knowing this, we can write out an equation:
u* = 18
u = 
<u>Multiply both sides by </u><u> in order to get rid of the root in the denominator:</u>
u = 
u = 
u = 9
If you'd like me to explain how I got to the answer any further, just ask!
