and,  the boutique merged with another store, and the staff members started making $24 per hour.

To find the what percent increase in pay ?

Now, According to the question:

Based on the given conditions,

= (24 - 20) ÷ 20

= [tex]\frac{24-20}{20}[/tex]

= 1/5

and, Covert to percentage

= 1/5 x 100

= 20%

Hence, The percent increase in pay was 20%

What is Percentage?

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. The formula used to calculate percentage is :

$3,708.33 is withheld monthly for state taxes.

Some states have a graduated income tax that involves a different tax rate for each of several levels of income. The tax rate increases as income increases.

Tax Withheld per Pay Period = Annual Tax Withheld/ Number of Pay Periods per Year

Here, we are given that Kerry McCarthy is a news traffic reporter with an annual gross pay of $44,500.

Thus, the Annual Tax Withheld = $44,500.

He is paid on a monthly basis ⇒ Number of Pay Periods per Year = 12

Hence, we get-

Tax Withheld per Pay Period = 44,500/ 12

= 3,708.33

Thus $3,708.33 is withheld monthly for state taxes.

The inequality that describes the possible temperatures on Mars is

 -133°c ≤T≤ -7°c .

Inequality compares two values by if they are less than or greater than each other.

According to the given question Mars has a maximum temperature of -7°c at the equator and a minimum temperature of -133°c at the winter pole.

We have to write an inequality that describes the possible temperatures on Mars.

Let us denote all the possible range of temperatures by T,

∴ T is less or equal to the maximum temperature and T is greater than or equal to the minimum temperature.

So,    -133°c ≤T≤ -7°c .

Answer: probably like 1.8%

Step-by-step explanation:

8 halls would be required to accommodate 520 people in the hall.

As we know that a hall can accommodate 65 people.

To determine the number of hall required for 520 people,

first we need to find that how many halls would be required for one person,

So, we will divide the 1 by 6 to find :

The number of one person accommodate = 1/65 Hall

Then, 520 people required to accommodate = 1/65 × 520

                                                                      = 8 Halls.

The model that best described the statement is an exponential model and the function that models the situation is A(t) = 4^t

The statement is given as:

The above statement is a population function

Population functions are best represented by an exponential function

Hence, the model that best described the statement is an exponential model.

Here, we have

Initial value, a = 1

Rate, r = 3

The function is represented as

A(t) = A * (1 + r)^t

So, we have

The average rate of change of the function from x == -4 to x = 3 is calculated as: -26.

The formula for determining the average rate of change across a given interval of a function is expressed as:

Average rate of change = g(b) - g(a)/b - a.

Given the function, g(x) = -2x³ + 5 to find the average rate of change from x = -4 to x = 3, do the following:

a = -4

g(a) = g(-4) = -2(-4)³ + 5 = -2(-64) + 5 = 128 + 5 = 133

b = 3

g(b) = g(3) = -2(3)³ + 5 = -2(27) + 5 = -54 + 5 = -49

Substitute the values into g(b) - g(a)/b - a:

Average rate of change = (-49 - 133)/(3 - (-4))

Average rate of change = -182/7

Average rate of change = -26

Thus, the average rate of change of the function from x == -4 to x = 3 is calculated as: -26.

The function is a good model for the data, capacity U. S. nuclear power plants were working in 2014 is 115% and the year when nuclear power plant working with full capacity is 2008.

Given that the table which shows the capacities at which U.S. nuclear power plants are working and a model of the situation is f(t)=0.027t²+0.216t+53.296.

The Scatter plot for our function and points is shown in attached image and the point are highly related to the curve .

So the function is good model.

The year 2014 means t=2014-1970=44

So to get the population,put t=44 in equation

f(t)=0.027(44)²+0.216(44)+53.296

f(t)=0.027(1936)+0.216(44)+53.296

f(t)=52.272+9.504+53.296

f(t)=115.072

And on rounding it we get 115%.

Now, to find year at which capacity is 100% ,put f(t)=100 and solve for t

f(t)=0.027t²+0.216t+53.296=100

0.027t²+0.216t+53.296=100

0.027t²+0.216t+53.296-100=0

0.027t²+0.216t-46.704=0

Now, we will solve this using quadratic formula for f(x) =ax²+bx+c=0

[tex]\begin{aligned}x&=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}\end[/tex]

for our function a= 0.027 , b=0.216 ,c=-46.704 substitute this value and we get

[tex]\begin{aligned}t&=\frac{-0.216\pm \sqrt{(0.216)^2-4\times 0.027\times (-46.704)}}{2\times 0.027}\\ &=\frac{-0.216\pm \sqrt{0.046656+5.044032}}{0.054}\\ &=\frac{-0.216\pm \sqrt{5.090688}}{0.054}\\ &=\frac{-0.216\pm 2.256}{0.54}\\ &=37.78, -45.78\end[/tex]

As we all know time cannot be negative so t=-45.78 will be rejected.

So, t=37.78=38

Now, we will find the corresponding year

1970+38=2008

Hence, from the given table the function is a good model for the data, capacity U. S. nuclear power plants were working in 2014 is 115% and the year when nuclear power plant working with full capacity is 2008.

As the name suggests place value is where the digit is being placed in decimal number system.

We can multiply both these numbers by 100 in that way we'll get rid of the decimal and it doesn't effect our answer.

Now 7.8 and 23.97 multiplied by 100 becomes 780 and 2397.

We can observe that 7 in 780 is in hundreds place and 7 in 2397 is in ones place.

Answer:

No solution.

Explanation:

Given expression:

when x = 3, y = 4

Substitute these values inside expression:

6(3) + 4(4) = 36

34 = 36

As the statement "34 = 36" not true. The solution is false or no solution.

Answer:

The given values are wrong.

Step-by-step explanation:

Given information,

→ x = 3

→ y = 4

Solving the given equation,

→ 6x + 4y = 36

→ (6 × 3) + (4 × 4) = 36

→ 18 + 16 = 36

→ 34 ≠ 36
