A store manager wants to determine how much to pay her employees. The number of hours the employees work is x, and the hourly wage that they are paid is y. The store manager is willing to pay the employees a wage given by the equation 10y-30x=20 . The business owner states that the employees should be paid a wage given by the equation 6y+30x=60. If the two equations were added then simplified to determine hourly wage, y, how much would the employees be paid?

Answers

Answer:

The employees will work for 1 hour, will earn $5 per hour and will be paid $5

Step-by-step explanation:

System of Equations

The number of hours the employees work is x.

And the hourly wage that they are paid is y. The store manager is willing to pay the employees a wage given by the equation

10y-30x=20

The business owner states that the employees should be paid a wage given by the equation

6y+30x=60

Adding both equations we have:

16y = 80

Dividing by 16:

y = 80/16 = 5

Substituting into the first equation:

10*5-30x=20

Operating and simplifying:

50-30x=20

50 - 20 = 30x

30x = 30

x = 30/30 = 1

Thus, the employees will work for 1 hour, will earn $5 per hour and will be paid $5

Find the percent change from the first value to the second.

Answers

Answer:

Change in percent = 30%

Step-by-step explanation:

Given:

First value = 30

Second value = 39

Find:

Change in percent

Computation:

Change in percent = [(Second value - First value) / First value]100

Change in percent = [(39 - 30) / 30]100

Change in percent = [(9) / 30]100

Change in percent = 30%

What is a triangle?

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points.

Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know, In a triangle if one segment is parallel to one side of a triangle divides the other two sides in the ratio of their corresponding lengths.

Given, AB = 12, AC = 16 and ED = 5, hence BC = AC - AB = 4.

Therefore, AB/BC = AE/ED.

12/4 = AE/5.

4AE = 60.

AE = 15 units.

The combined area of a pair of congruent rectangles can be represented, in square units, by the expression 18y^2-818y 2 −8. The length and side of each rectangle can be represented as a difference of squares. What is the perimeter of one of the rectangles?

Answers

Answer:

[tex]Perimeter = 12y[/tex]

Step-by-step explanation:

Given

[tex]Area = 18y^2 - 8[/tex] -- two rectangles

Required

Determine the perimeter of one of the rectangles

First, calculate the area (A) of 1 rectangle

[tex]A =\frac{1}{2}Area[/tex]

[tex]A =\frac{1}{2}(18y^2 - 8)[/tex]

[tex]A =9y^2 - 4[/tex]

Express as difference of two squares

[tex]A =(3y - 2)(3y+2)[/tex]

Area is calculated as:

[tex]A = Length * Width[/tex]

So, by comparison:

[tex]Length = 3y - 2[/tex]

[tex]Width = 3y + 2[/tex]

The perimeter is:

[tex]Perimeter = 2 *(Length + Width)[/tex]

[tex]Perimeter = 2 *(3y-2+3y+2)[/tex]

Collect Like Terms

[tex]Perimeter = 2 *(3y+3y-2+2)[/tex]

[tex]Perimeter = 2 *(6y)[/tex]

[tex]Perimeter = 12y[/tex]

What is the y-coordinate for the solution to the system of equations?

{y=1/2x−4
{y=−2x+1

Answers

Answer:

y = -3

Step-by-step explanation:

{y = x/2 - 4

y = 1 - 2 x

Substitute y = x/2 - 4 into the second equation:

{y = x/2 - 4

x/2 - 4 = 1 - 2 x

In the second equation, look to solve for x:

{y = x/2 - 4

x/2 - 4 = 1 - 2 x

Add 2 x + 4 to both sides:

{y = x/2 - 4

(5 x)/2 = 5

Multiply both sides by 2/5:

{y = x/2 - 4

x = 2

Substitute x = 2 into the first equation:

{y = -3

x = 2

Answer:

t = 19 1/4

Step-by-step explanation:

24 1/2 = t + 5 1/4

49/2 = t + 21/4

t + 21/4 = 49/2

t = 49/2 - 21/4

t = 98/4 - 21/4

t = 77/4

t = 19 1/4

24 1/2 = 24.5, 5 1/4 = 5.25

24.5 = t + 5.25
subtract 5.25 from both sides
19.25 = t

19.25 = 19 1/4

Various Forms of Digital Communication Outlets Question 4(Multiple Choice Worth 5 points)[06.05 MC]Excerpt taken from The Historic Rise of Old Hickory by Suzanne B. WilliamsFour major candidates ran in the 1824 election, all under the "Democratic-Republican" name. One of the candidates, Andrew Jackson, was already famous. In the 1780s, he earned the right to practice law and served in various offices of the state government, including senator. He earned the nickname "Old Hickory" for his toughness as a general during the War of 1812 and First Seminole War. Jackson supported slavery and "Indian removal." This earned him support from voters in southern and frontier states. The other three candidates were John Quincy Adams of Massachusetts, Henry Clay of Kentucky, and William Crawford of Georgia. U.S. presidents are elected through the Electoral College. The Founding Fathers worried that Americans were too spread out to learn enough about the candidates. Under the Electoral College, Americans cast their ballot for the popular vote, which chooses the electors for each state. The number of electoral votes each state equals the number of representatives and senators combined. The candidates must win an absolute majority of electoral votes to win the election.In 1824, Andrew Jackson won the popular vote, but he did not win it in each state. Jackson and Adams both won many electoral votes. Jackson won the most with 99. However, a candidate needs an absolute majority of electoral votes to win. In 1824, Jackson needed 131 to win. When there is not majority winner, the election goes to the House of Representatives. This has only happened twice in U.S. history.Even though he won the popular vote and many electoral votes, Andrew Jackson lost the presidency in 1824. John Quincy Adams was the Secretary of State at this time. Henry Clay was the Speaker of the House of Representatives. Henry Clay, receiving the least, was left out. However, as a leader in the House of Representatives, he had influence over the other members. Clay openly hated Jackson and there were rumors that Clay made a deal with Adams in exchange for his support. The House election declared John Quincy Adams president. Soon, he chose Henry Clay to fill the seat he left vacant, Secretary of State. Jackson was shocked and enraged. Although there was no inquiry of possible wrongdoing, Jackson accused Adams and Clay of making a "corrupt bargain."John Quincy Adams was a disappointment as president. Many of his goals created divisions like federal funds for internal improvement. Some states thought that taking federal funds would force them to follow certain rules. They felt this reduced their rights as independent states. Jackson took advantage of issues like this one to gather more support. More Jackson supporters found their way to seats in Congress. He was as a man of the people and said Adams could never understand the common mans concerns.John Quincy Adams ran against Andrew Jackson in the 1828 election. Personal attacks grew even more vicious, but Andrew Jackson appealed to many. He believed government was for the common man. He believed in strict reading of the law and limited internal improvements. He also believed in states rights. Andrew Jackson easily won the 1828 election, winning both the popular vote and a majority of electoral votes. Historians note the sectional nature of the voting. Support for Jackson was concentrated in South while Adams support was mostly in the North. Jackson was so popular because he brought changes to the government. He also wanted to make sure the government was responsible for its actions. Jackson pushed settlement into the frontier. He supported the Indian Removal act. He also defended the spread of slavery. Though his support was heavier in the South, he was determined to keep a unified nation. The rise and presidency of Old Hickory is memorable to Americans today. Which of the following did Andrew Jackson not support? A limited national government Spreading of slavery to the frontier Federal funds for internal improvements A strict interpretation of the U.S. Constitution 4) (Economies of Scale) Suppose a firm has chosen its quantity so that its marginal cost is equal to the market price, and is making positive profits because its revenues exceed its costs.
