Select the correct answer. Anna learns in her science class that the human eye blinks an average of 4,200,000 times a year. What
vivado [14]

Answer:

Step-by-step explanation:

A. 4.2E6 because when putting a number into scientific notation, you would want one number in front of the decimal place and then the trailing numbers would follow. The exponent or E stand for how many numbers are after the decimal, which in this case would be 6.  

4,200,000 → 4.2 x 10^6 which is equal to saying 4.2E6

Tip: If the exponent is negative than the decimal would go in the opposite direction. For example:

4,200,000 → 4.2 x 10^-6 would not equal each other because 4.2 x 10^-6 means 0.000004, six numbers would be behind the decimal.

I already know the answer to this problem, I want a explanation on how to get the answer.
DochEvi [55]

\\ \bull\tt\dashrightarrow BC=CE

\\ \bull\tt\dashrightarrow 3x+3y=7x+5y

\\ \bull\tt\dashrightarrow 7x-3x=3y-5y

\\ \bull\tt\dashrightarrow 4x=-2y

\\ \bull\tt\dashrightarrow 2x=-y

\\ \bull\tt\dashrightarrow \dfrac{x}{y}=\dfrac{-1}{2}

Now

\\ \bull\tt\dashrightarrow BE=BC+CE+CD

\\ \bull\tt\dashrightarrow BE=3x+3y+7x+5y+5x-2y+6

\\ \bull\tt\dashrightarrow BE=15x+6y+6
