8.0464x10^-7 = <br> answer in decimal notation
Charra [1.4K]
To convert 8.0464x10^-7 from scientific notation to decimal notation, you need to move the decimal point to the left seven times.
Therefore the answer is:

0.00000080464

Note: 10^-7 equals 1/10^7
8.0464x10^-7 can be rewritten as:
8.0464/10^7 (i.e. divide 8.0464 by 10000000)
which results: 0.00000080464

3. Suppose m4 = (3x + 5)º and m5 = (x +95), where x = 20. Are the lines parallel? Explain.
lions [1.4K]
No, 3(20)+5=65 and 20+95=115.
65 is not equal to 115; therefore they are not parallel because they are not congruent.
