34.7% of city employees ride the bus to work. Last year, 5.2% of city employees rode the bus to work. What is the relative chang

DaniilM [7]

Answer:

$5.67\%$

Step-by-step explanation:

The relative change is defined by the following equation:

$Relative\hspace{3}change=\frac{x-x_r_e_f_e_r_e_n_c_e}{x_r_e_f_e_r_e_n_c_e}$ (1)

Where:

$x=Value\hspace{3}of\hspace{3}indicator\hspace{3}in\hspace{3}period\hspace{3}2$

$x_r_e_f_e_r_e_n_c_e=Value\hspace{3}of\hspace{3}indicator\hspace{3}in\hspace{3}period\hspace{3}1$

With this in mind, let's replace the values in the equation (1):

$Relative\hspace{3}change=\frac{34.7-5.2}{5.2}=\frac{29.5}{5.2}=5.673076923\approx5.67\%$

Pre Calc for one of my classes

GREYUIT [131]

Use index form. N= a^x becomes log a (N) = x
Therefore your question becomes (log 2.3 (13))/9 = x
And rounding to 3 decimals gives you 0.342

Breyana is buying a new dress. The dress is on sale for 20% off. Breyana will also have to pay 10% sales tax on the discounted p

Vinvika [58]

Answer:

Breyana paid 88% of the dress's original price.

Step-by-step explanation:

We are given the following in the question:

Let x be the original price of dress.

The dress is on sale for 20%.

Price of dress after discount =

$(x-0.20x)$

Breyana will also have to pay 10% sales tax on the discounted price of the dress.

Price of dress after discount =

$0.10(x-0.20x)$

Total cost of dress =

$(x-0.20x) + 0.10(x-0.20x)$

We have to calculate percentage of original price paid by Breyana

$\dfrac{(x-0.20x) + 0.10(x-0.20x)}{x}\times 100\%\\\\=\dfrac{0.80x+0.08x}{x}\times 100\%\\\\=\dfrac{0.88x}{x}\times 100\%\\\\=88\%$

Thus, Breyana paid 88% of the dress's original price.

Stells [14]

Add the two values being multiplied by m
37.26 + 2.7 = 39.96
39.96 m + 0.0015 is the most simplified you can get without having a way of finding the value of m. I apologize if I am mistaken, but I'm fairly certain! :)
