Answer:
The given three expressions can be written as statements.
The three expressions are,
1). <u>Statement for 4n</u>
4n - Four times of a number 'n'
2). <u>Statement for r/2</u>
r/2 - One by half of a number 'r'
3) <u>Statement for t - 5</u>
t - 5 - Five is subtracted from a number 't'
These are the three statements of the given expressions
Answer:
There will be 22.5 grams left after 32 hours.
Step-by-step explanation:
A half-life is how long it takes for half of the amount to go away. In this case, we see that we have two half-life periods worth, which you can determine by dividing the total time by the half-life time.
32hrs/8hrs = 4 half lives.
Now we can raise 1/2 to the power of how many half lives we have (2). Then we multiply that by the amount in the sample.
(1/2)^4 * 360
1/16 * 360
22.5 grams
And this is an exponential function.
You can rewrite this expression as 1800 x (1/1.2)^t
Now you just simplify
= 1800(10/12)^t
= 1800 (5/6)^t
So B is your answer!
Answer:
6
Step-by-step explanation:
3! or 3x2x1 because there are 3 different choices at the first, 2 choices on the second and the last flavour is third.
6(54 + 48). I'm not sure what this question is asking but the GCF is 6. That is all I did pretty much.
