A
Step-by-step explanation:
$\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad6\frac{2}{3}=\frac{20}{3}$
=8\div \frac{20}{3}
=\frac{8}{1}\div \frac{20}{3}
=\frac{8}{1}\times \frac{3}{20}
=\frac{2}{1}\times \frac{3}{5}
=\frac{2\times \:3}{1\times \:5}
=\frac{6}{1\times \:5}
=\frac{6}{5}
Convert improper fractions to mixed numbers
=1\frac{1}{5}

15x would be the vertical angle of 16x -8 and since vertical angles are equal, then 15x = 16x -8.
15x = 16x -8
x = 8 and so the angle 15x = 15 * 8
which equals 120 degrees.

Answer: 83.85%</h3>
This value is approximate.
==========================================================
Explanation:
Let's compute the z score for x = 40
z = (x-mu)/sigma
z = (40-47)/7
z = -1
We're exactly one standard deviation below the mean.
Repeat these steps for x = 68
z = (x-mu)/sigma
z = (68-47)/7
z = 3
This score is exactly three standard deviations above the mean.
Now refer to the Empirical Rule chart below. We'll add up the percentages that are between z = -1 and z = 3. This consists of the two pink regions (each 34%), the right blue region (13.5%) and the right green region (2.35%). These percentages are approximate.
34+34+13.5+2.35 = 83.85
<u>Roughly 83.85%</u> of the one-mile roadways have between 40 and 68 potholes.

Step-by-step explanation:
Simplify \frac{4}{5}G

G to \frac{4G}{5}

4G
.
\frac{4G}{5}+42=2.8G+18
5
4G
+42=2.8G+18
Multiply both sides by 5.
4g + 210 = 14g + 90
Simplify
14G + 90 - 4G to 10G + 90
Subtract 90 from both sides.
210-90=10G210−90=10G
Simplify 210-90210−90 to 120120.
120=10G120=10G
Divide both sides by 1010.
\frac{120}{10}=G

120
=G
Simplify \frac{120}{10}

to 1212.
12=G12=G
Switch sides.
G=12G=12
