What is the difference written in scientific notation? 0.00067 - 2.3 x 10^5

Mathematics

0.00067=67X10^5 so

67X10^5-2.3X10^5

64.7X10^5 which can be expressed as:

6.47X10^6

(not sure if it matters to you or not, but technically we only had two significant figures so it should be rounded to 6.5X10^6)

2x+3y=41 and 5x+4y=85
Sever21 [200]

Answer:

5x+4y=85-

 Slope = -2.500/2.000 = -1.250

 x-intercept = 85/5 = 17

 y-intercept = 85/4 = 21.25000

2x+3y=41-

 Slope = -1.333/2.000 = -0.667

 x-intercept = 41/2 = 20.50000

 y-intercept = 41/3 = 13.66667

The diameter of Mercury is approximately 4.9×103 kilometers. The diameter of Saturn is approximately 1.2×105 kilometers. About h
soldier1979 [14.2K]

As soon as you see "How many times . . .", that usually tells you that finding the answer involves <em>division</em>.  (It certainly does in this one.)

(1.2 x 10⁵) / (4.9 x 10³)  =  

(1.2/4.9) x (10⁵⁻³)  =

0.245 x 10²  =  <em>24.5 times</em>

It looks like  <em>B</em>  is the closest choice.
