Find the answer to zero point 73 repeating times square root of 147 end square root and select the correct answer below. Also, i

Answer:

$\frac{511\,\,\sqrt{3} }{99}$ which is an irrational number

Step-by-step explanation:

Recall that the repeating decimal 0.7373737373... can be written in fraction form as: $\frac{73}{99}$

Now, let's write the number 147 which is inside the square root in factor form to find if it has some perfect square factors:

$147=7^2\,3$

Then, 7 will be able to go outside the root when we compute the final product requested:

$\frac{73}{99} \,*\,7\,\sqrt{3} =\frac{511\,\,\sqrt{3} }{99}$

This is an irrational number due to the fact that it is the product of a rational number (quotient between 511 and 99) times the irrational number $\sqrt{3}$

A restaurant offers diet soda and regular soda. In one day they sold 14 diet sodas. If the ratio of diet sodas sold to regular s

finlep [7]

Answer: 26 sodas.

Step-by-step explanation:

Let be "x" the number of regular sodas that were sold in that day.

You know that the the ratio of diet sodas sold to regular sodas sold was:

$7 : 6$

This ratio can also be written as a fraction:

$\frac{7}{6}$

Knowing that in that day they sold 14 diet sodas, you can write the following proportion:

$\frac{7}{6}=\frac{14}{x}$

Now solve for "x":

$(x)(\frac{7}{6})=14\\\\x=(14)(\frac{6}{7})\\\\x=12$

Then the total number of sodas sold that day is:

$Total=14\ sodas+12\ sodas=26\ sodas$

Kisachek [45]

The method that results in more money after 2 years is Peggy's investment.

<h3>Which method results in more money in 2 years?</h3>

The formula for calculating the future value of an investment:

FV = P (1 + r)^nm

FV = Future value
P = Present value
R = interest rate
m = number of compounding
N = number of years

Future value of Larry's investment: $350 x [1 + (0.04/4)]^(4 x 2) = $379

Future value of Peggy's investment: $350 x [1 + (0.06/12)]^(12 x 2) = $394.51
