Answer:
I think it is B sorry if it is wrong;-; have a good day
Answer:
cells
Step-by-step explanation:
Let the number of cells she used in 2nd experiment be "x"
Since the latter experiment she uses LESS, we can say:
"<em>What number times 2000 gives us 2.8 * 10 ^ 12??"</em>
<em />
We can create an equation such as:
Thus, x would be:
Let's convert 2000 into scientific notation first. We would take decimal point to the left until we have 1 digit to left of decimal and make 10 raised to that many units we take left "to the power".
So
2000 = 2 * 10 ^3
Now, let's remember rule of dividing numbers in scientific notation:
Now, we do our problem using this rule:
Thus, she used cells in her 2nd experiment
Answer:
the common denominator for the first question is 36
So 36, to get that you multiply 4 by 9 and 9 by 4.
you’d get
3 4/36 + 2 9/36
you’d get 5 13/36
That bai scaly answers both parts
Y= mx+b (I think) m is the slope, and b is the y intercept
So excluded values are x=3 and x=-2. Fully simplified form:
