You already have figured the main idea. In this case, the population is growing 1.9% a year. This word can be translated into: multiplied by 101.9% (100+1.9%). That means the P0 is 6 bill, the base is 101.9%(or 1.019) and the time is 50 years. The calculation would be:
<span>P(t)=P₀a^t
</span>P(t)=6 billion * 101.9%^50= 6 billion * <span>2.56276= 15.38 billion</span><span>
</span>
This is a question about finding the GCF or the greatest common factor for these two numbers. The real question there is what is the largest number that both 56 and 64 can be divided by and still give out integers (meaning, whole regular counting numbers). This number turns out to be 8. 56/8 = 7. 64/8 = 8. The GCF gets pulled to the outside of the parenthesis and the divided numbers remain on the inside being added together. It looks like this, 8(7+8).
Answer:
32
Step-by-step explanation:
(5^2)+7
5^2 = 5×5 =25
25 + 7 = 32
Answer:
=2.5×10^-5
Step-by-step explanation:
it's 0.00025
2x+5=4x-7 that's the equation.
The number is 6, I believe. The way to do that is...
You have to put 2x on the other side
then add 7 to both sides
then divide both sides by 2
here is the worked out thing ↓↓↓
2x+5=4x-7
-2x -2x
---------------
5=2x-7
+7 +7
------------
12=2x
/2 /2
--------
6=x
