Scientific notation is used so that the order of the number is known in first glance. The value of the given number in scientific notation is given by: Option B: 
<h3>How does scientific notations work?</h3>
The number is written in the form
where we have 
The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
Scientific notations have some of the profits as:
- Better readability due to compact representation
- Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.
For the given case, the number in consideration is 0.0000069
Rewriting it in fraction form, we get:

(we used two facts: first that : 
and second that: 
Thus, the value of the given number in scientific notation is given by: Option B:

Answer:
0.81
Step-by-step explanation:
81% The decimal is where the percentage is so remove the percentage and move the decimal two times to the left
10*(6/5)=12
12*6=72
Volume of dilated prism = 72^3 feet
means "all measurements are increased by the factor of 6/5
Then the volume is increased by the factor of (6/5)^3 = 216/125
The volume of the dilated prism is (5*10)*(6/5)^3 = (5*10)*(216/125) =
86.4 cupid feet
plz mark me as brainliest :)
Answer:
The answer to your question is: ST = 27
Step-by-step explanation:
Data
SR = 2x+ 7
ST = x - 6
RT = 100
Process
SR + ST = RT
2x + 7 + x - 6 = 100
3x = 100 - 1
3x = 99
x = 99/ 3
x = 33
ST = 33 - 6
ST = 27
A = bh
A = 8 x 7 = 56 cm^2
