Answer:
To multiply two numbers in scientific notation, multiply their coefficients and add their exponents. To divide two numbers in scientific notation, divide their coefficients and subtract their exponents. In either case, the answer must be converted to scientific notation.

Answer: A) 1/10</h3>
=============================================
Work Shown:
(4/5) divided by 8
(4/5) divided by (8/1)
(4/5) * (1/8) .... flip the second fraction and multiply
(4*1)/(5*8)
(4*1)/(5*4*2)
1/(5*2) ... the '4's cancel
1/10
--------------
Alternative method:
4/5 = 0.8 when using a calculator or long division
(4/5) divided by 8 = 0.8/8 = 0.1
0.1 = 1/10
The digit 1 in 0.1 is in the tenths place, so that's why 0.1 = 1/10
Or you could use your calculator to see that 1/10 = 0.1
Another idea is to do
0.1 = 0.1/1 = 0.1/1.0 = 1.0/10.0 = 1/10
here I moved the decimal point 2 spots to the right for the numerator and denominator.

Answer:
w < -5
Step-by-step explanation:
Let's do it !
(6.7 ≥ -0.2x + 4.5)
↔ (6.7 - 4.5 ≥ -0.2x)
↔ (2.2 ≥ -0.2x)
↔ (2.2/-0.2 ≤ x)
↔ (-11 ≤ x)
In short, the answer would be : D. x ≥ -11.
Hope this helps !
