Order the following numbers written in scientific notation from greatest to least: 3.9 × 105, 6.1 × 103, 9.3 × 105, 1.6 × 103 a. 9.3 × 105, 3.9 × 105, 6.1 × 103, 1.6 × 103 b. 1.6 × 103, 6.1 × 103, 9.3 × 105, 3.9 × 105, c. 3.9 × 105, 9.3 × 105, 1.6 × 103, 6.1 × 103,

The numbers are:

3.9 × 105 = 409.5

6.1 ×103 = 628.3

9.3 × 105 = 976.5

1.6 × 103 = 164.8

Arranging from greatest to least and in scientific notation form gives:

9.3 × 105 , 6.1 × 103 , 3.9 × 105 , 1.6 × 103

*(Seems like there is no correct answer from the choices given there).

55% are girls and 45% are boys : ) hope this

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
