Molly's town voted on a new speed limit. Out of 38 votes, 19 were in favor of the new speed limit. What percentage of the votes

RUDIKE [14]

Answer:

Percentage of votes in favour of new speed limit=50%

Step-by-step explanation:

There was a voting in Molly's town to set a new limit for the speed attained by a vehicle.

In Molly's town,

Number of votes recorded=38

Number of votes in favour of the new speed limit=19

We have to find the percentage of votes in favour of the new speed limit.

For that,the percentage of votes in favour= $\frac{votes in favour of new speed limit×100}{total votes}$

Percentage of votes in favour= $\frac{19*100}{38}$

Percentage of votes in favour=50%

Use the following work shown below to answer the following question.

zysi [14]

Answer:

$\frac{3 + \sqrt{3x} }{3 - x}$

Step-by-step explanation:

You can use the work they gave you and continue from there:

$\frac{\sqrt{3}(\sqrt{3}) + \sqrt{3}(\sqrt{x}) }{(\sqrt{3}) ^{2} - (\sqrt{x} )^{2} }$

First, simplify the numerator:

$\frac{3 + \sqrt{3x} }{(\sqrt{3}) ^{2} - (\sqrt{x}) ^{2} }$

Finally, simplify the denominator:

$\frac{3 + \sqrt{3x} }{3 - x}$
