The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 7 to 4. If there were 6

Nikolay [14]

Answer:

3,500 no votes

Step-by-step explanation:

There were 7 yes votes to every 4 no votes. There were a total of 6,125 yes votes, so set up a proportion to find the number of no votes

Let x represent the number of no votes

7 is to 4 as 6,125 is to x

We get

7/4 = 6,125/x

Now solve for x

First cross multiply

7x = 24,500

Divide both sides by 7 to isolate x..

x = 3,500 no votes

Help me solve this....

rodikova [14]

Answer:

$1. Solution,\\Let~x=0.272727......\\Then, 100x = 27.272727.....\\Now,\\100x-x = 27.272727..... - 0.27272727..... = 27.\\or, 99x = 27\\or, x = \frac{27}{99} = \frac{3}{11}\\Thus,~\frac{3}{11} =0.27272727......\\$

$2. (27)^\frac{2}{3}.(125)^\frac{1}{3}\\= (3^3)^\frac{2}{3}.(5^3)^\frac{1}{3}\\=(3^2)(5)\\=45.$

$3. Solution,\\Here, \frac{1}{5} = 0.2\\\frac{1}{2} = 0.5\\Now, ~Irrational~ numbers~ between~ 0.2 ~and~ 0.5 ~are~ 0.2122275647.......~and~0.467858930.......\\$

You can write any numbers between 0.2 and 0.5 which follow irregular patterns like this.

$OR\\Examples~of~such~irrational~numbers~are~5+\sqrt{7}~ and~5-\sqrt{7} .$

$4. Solution,\\x^2+y^2 = (x+y)^2-2xy=5^2-2(10) = 25-20=5.\\5.~ If~x=-3~and~y=-2~are~the~solutions~of~the~equation~2x-3y=k,~then,\\2(-3)-3(-2)=k\\or, k = -6+6\\or, k = 0$
