Answer:

$-36$ goes into the box

Step-by-step explanation:

Let the number be $x$ , then

$(m^x)^{\frac{1}{3}}=m^{-12}$

We now use the following property of exponents to simplify the left hand side of the equation.

$(a^m)^n=a^{mn}$

This implies that;

$m^{x\times \frac{1}{3}}=m^{-12}$

$\Rightarrow m^{\frac{x}{3}}=m^{-12}$

Since the bases are the same, we equate the exponents to get;

${\frac{x}{3}=-12$

We now multiply both sides by 3 to get;

$\frac{x}{3}\times 3=-12\times 3$

$\Rightarrow x =-36$

Therefore the number that goes into the box is $-36$

In 2002, the number of students in a large urban high school was 2260. In 2004, the number of students was 2230. If the number o

Alchen [17]

Its saying that every 2 years the students decreases by 30 such as in 1990 the number of students in an large urban high school is 3490.In 1992 the number of students was 3460 and keep decreasing every 2 years 30 comes off.
The easiest way to move faster is to:
Years=The Number Of Students
2006=2200
2008=2170
2010=2140
2012=2110
2014=2080
2016=2050
But here is the tricky part the question said 2017 it an odd number so we have half of 30 because 30 comes of every 2 years but its the 1st year so it half of the 2 years and half of 30 students so this equals to:
2017=2035

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
