A worker earns $5.15/h receives a raise. She now earns $6/h. Find the percent of increase in her hourly rate of pay.

Svetllana [295]

Answer:

The percentage increase in worker wages in hourly rate of pay is 16.5%

Step-by-step explanation:

Given as :

The Initial wages earn by worker = $ 5.15 per hour

The Final wages earn by worker = $ 6 per hour

Let The percentage increase in her hourly rate of pay = x %

Now, According to question

x % = $\dfrac{\textrm Final earning - \textrm Initail earning}{\textrm Initial earning}$

or, x = $\dfrac{\textrm $ 6 - \textrm $ 5.15}{\textrm $ 5.15}$ × 100

or, x = $\frac{0.85}{5.15}$ × 100

or, x = 0.165 × 100

∴ x = 16.5%

So , Percentage increase in wages = x = 16.5 %

Hence The percentage increase in worker wages in hourly rate of pay is 16.5% Answer

Gwen has recently purchased a cottage. She has arranged

Aleksandr-060686 [28]

A) 0.8
B) 0.24
C) 0.56
D) 0.44

For A, since 1 in 5 is dry, 4 in 5 are not; 4/5 = 0.8

For B, we know that 30%, 0.3, of the ones that are not dry are contaminated:
0.3(0.8) = 0.24

For C, 100%-30%=70% of wells that are not dry are not contaminated; 0.7(0.8) = 0.56

For D, she will either have contaminated water or no water:
0.24+0.2 = 0.44

Simplify the complex fraction: ((3x-7)/x^2)/(x^2/2)+(2/x)

Archy [21]

Simplify the complex fraction: ((3x-7)/x^2)/(x^2/2)+(2/x)

$\dfrac{ \dfrac{3x-7}{x^2} }{ \dfrac{x^2}{2} } + \dfrac{2}{x} =\qquad \qquad x \neq 0\qquad x^4 \neq 0 \\ \\ \\ \dfrac{(3x-7)*2}{x^2*x^2}+ \dfrac{2}{x} = \\ \\ \\ \dfrac{6x-14}{x^4}+ \dfrac{2}{x} =\\ \\ \\ \dfrac{ 6x-14 }{ x^4 }+ \dfrac{2(x^3)}{x(x^3)}=\\ \\ \\ \boxed{ \dfrac{ 6x-14 +2x^3}{ x^4 } }$
