Jillian wants to buy an $80 pair of boots. Before she can, the store raises the price by $24. By what percentage did they raise the price? Use proportions to solve the problem.

Answer:

y=x^2 - 8x +8:

(1.8,0) and (6.8)

y=-x^2-4x+7:

(-5.3,0) and (1.3,0)

If you go to desmos graphing calculator online, you can type the equation in and click on the zeros.

I have attached the following graphs to show what I did to find them.

Answer: 52.1

Step-by-step explanation:

In this situation, it is true buying three pairs of socks costs less at the store and buying fout pairs costs the same online and in the store.

Store: $5 x 3 = $15

Online: $3.50 x 3 = $10.5 + $6 = $16.5

This shows buying three pairs cost less at the store, which makes the first statement correct.

Store: $5 x 4 = $20

Online: $.3.50 x 4 = $14 + $6 = $20

This shows buying four pairs is the same in the store or online.

The high-tech sector employees were less likely to lose their jobs option fourth is correct.

It is given that the estimated employment change by sector 2004–2020 a bar graph titled estimated employment change by sector from 2004 to 2020 has the year on the x-axis and the percentage of change in employment on the y-axis.

It is required to find the correct statement.

It is defined as the visual way to show the data a systematically with rectangle box on the x-axis and y-axis. The height and vertical lines show the proportional data.

From the given data many businesses stagnated and had to fire employees, but these were primarily people who could be quickly replaced by someone willing to work for a lower wage.

Employees in the high-tech sector are frequently too valuable to the company to be laid off, therefore their job security was strong because no one could replace them.

Thus, the high-tech sector employees were less likely to lose their jobs option fourth is correct.

Step-by-step explanation:

We can split this graph into cuboids and cubes.

Answer:

x²-7x+10=0
x²-5x-2x+10=0
x(x-5)-2(x-5)=0
(x-2)(x-5)=0 ANS!

Step-by-step explanation:

First we will multiply x² into 10, the answer will be 10x². Now, take L.C.M of 10, the L.C.M will be 5x2 or 2x5. Now we will make sure that:
2x x 5x=10x² while 5x+2x=7x. Now, we know that 7x is in negative so, we will change the signs and it will become x²-5x-2x+10=0. Now take common:
x(x-5)-2(x-5)=0. Now, write the common taken numbers first and then the other brackets in last i.e: (x-2)(x-5)=0

The intervals indicated on the graph are:

-7 < x < -3, -3 < x < -1, & 1 < x < 3 are increasing

-1 < x < 1, & 3 < x < 5 are decreasing

5 < x < 7 is neither

The interval of a function is increasing when the line slopes upward to the right along the interval. This means that the function value would increase as the input values decrease within the given interval.

On the other hand, the interval decreases when the line of the function slopes downwards within the interval. This implies that as the function value decreases, the input values increase within the given interval.

Therefore, from the graph given, we can conclude that:

-7 < x < -3: increasing

-3 < x < -1: increasing

-1 < x < 1: decreasing

1 < x < 3: increasing

3 < x < 5: decreasing

5 < x < 7: neither

Answer:

3/5, 1/5, 1/6

Step-by-step explanation:

3/5 is greater than 1/5 and is the largest of these three fractions.

Comparing 1/5 and 1/6, realize that the larger the denominator, the smaller the value of the fraction.  Thus, 1/5 is greater than 1/6.

Then, in order from greatest to least:  3/5, 1/5, 1/6

Answer: 25

Step-by-step explanation:

Answer:

it took the remaining two builders five days to finish

It takes 38 days to build the house for the remaining workers. Since it is said that the total working days for building a house with 8 workers is 20 and 6 workers left after 14 days and each worker is working at the same rate.

8 builders can finish a house in 20 days

Each builder works at the same rate

After 14 days 6 builders left.

When 6 builders left after 14 days, 2 builders have remained

Then, we can write

1 builder can finish the work that these 6 builders did in those 14 days is

6×14=84 days

Since it takes 20 days for 8 builders to finish a house, then for 1 builder it takes

1 builder = 20×8=160 days

Then the remaining left for 1 builder to finish the house is 160-84=76 days

Then the remaining 2 builders will build the house in 76/2 days

That is 38 days.

Therefore, the remaining builders build the house in 38 days at the same rate.

Step-by-step explanation:

[tex]y = |x + 2| [/tex]

____________________________________________

As you know all kind of vertical transfers are along the y-axis thus :

[tex]y = |x + 2| + 1[/tex]

____________________________________________

[tex]y = | x + 2| - 1[/tex]

_____________________________________________

Working with the operation along the x-axis are all opposite so when the question say transfer the graph on unit to left it means to decrease all x values by one unit and we have to do the inverse work with mean to increase all the x values by one unit :

[tex]y = |(x +1 ) + 2| [/tex]

[tex]y = |x + 3| [/tex]

_____________________________________________

[tex]y = |(x - 1) + 2| [/tex]

[tex]y = |x + 1| [/tex]

he used 24 ft² of wood to build the box.

James should earn a weekly salary of $ 432.76 with 0 exemptions to give the closest exemption.

In this question, we should estimate the salary earned before one exemption and find the equivalent brute salary with no exemptions. The expected salary is equal to product the brute salary minus the product of the tax rate and brute salary.

According to the table we have the expected salary after one exemption:

[tex]x = 418\cdot \left(1-\frac{19.66}{100} \right)[/tex]

[tex]x = 335.82[/tex]

After a quick inspection to the salary column for zero exemptions, we find that percentage associated to a salary with no exemptions: ([tex]r = 22.40\,\%[/tex])

[tex]C = \frac{335.82}{1-\frac{22.40}{100} }[/tex]

[tex]C = 432.76[/tex]

Answer:

well, y=8 and x=50

Step-by-step explanation:

you actually have the angle 128 wrong, and  it is suppose to be 32 degrees, which changes it up and all you have to do to find y because angle 32 and 4y are vertical, is divide 32/4=y which is 8, for x, it is vertical to 148 making those even, and it would be as simple as reversing the equation so, 148+2=150, and ddivided by 3 is 50 degrees

Answer:

x=50

y=8

Step-by-step explanation:

3x-2 and 148 are vertical angles and vertical angles are equal

3x-2 =148

Add 2 to each side

3x-2+2 =148+2

3x= 150

Divide by 3

3x/3 =150/2

x = 50

148 and the empty angle form a straight line so they add to 180

180-148 = 32

The empty angle is 32

4y  and 32 are vertical angles so they are the same

4y = 32

4y/4 = 32/4

y = 8

Answer:

Area= MULTIPLICATION

So, 13x9x4x15x10=70200

70200 Square inches.

There are two rectangles in the idiosyncratic shape. In order to find the area of the figure, we need to solve for one rectangle first.

The formula for solving the area of a rectangle is [tex]A = lw[/tex]. For the smaller rectangle on the left, we have both the length and width, so we can just multiply after plugging in the numbers into the equation; [tex]A = 13 * 4[/tex]. The 13 represents the length and the 4 represents the width. After solving, we get 52 inches squared for the first rectangle.

The larger rectangle, we already have the length and width as well, so we can just plug the numbers into the formula, [tex]A = 15 *10[/tex], as 15 represents the length and the 10 represents width. 15 × 10 = 150.

After doing this, we need to add up the two rectangles together, which we get a sum of 202. The total area of the figure is 202 inches squared.
