The new quantity supplied when the price is $348 per cord is 424.
What is the new quantity supplied?The supply curve is a graph that shows the relationship between price and quantity supplied. The supply curve has a positive slope.
The slope of the supply curve is the ratio of the change in the value of price divided by the change in the value of the quantity supplied.
Slope = change in price / change in quantity supplied
0.75 = ($348 - $255) / change in quantity supplied
0.75 = $93 / change in quantity supplied
change in quantity supplied = 93 / 0.75 = 124
The new quantity supplied = 300 + 124 = 424

The value of each letter in the given magic square is a = 30, b = 6 , c = 18 and d = 4.
What is a magic square?A magic square is one that has several different integers placed in such a way that the sum or total of the numbers is the same on all of the diagonals, as well as in every row, column, and major diagonal.
Given:
A magic square where all rows, columns, and diagonals sum to the same number.
Sum of the numbers in the diagonal of the magic square,
5 + 17 + 29 = 51
In the first row, the sum of numbers will also be 51
5 + a + 16 = 51
a = 51 - 21 = 30
Similarly, the sum in the first column
5 + 28 + c = 51
c = 51 - 33 = 18
And the sum in the last row,
c + d + 29 = 51
Putting the value of c, we get
18 + d + 29 = 51
d = 51 - 47 = 4
Now to find the value of b the sum of the last column,
16 + b + 29 = 51

The area of a triangle is given by the formula:
[tex]\begin{gathered} A=\frac{b\cdot h}{2} \\ \text{ Where b is the base and} \\ h\text{ is the height of the triangle} \end{gathered}[/tex]From the information given you know that the measure of the height of the triangle EFG is 16 cm but the measure of the base of the triangle is unknown.
To find the measure of the base, you can first find the measure of the middle of the segment EG using the Pythagorean theorem, since the triangle formed by the vertices F, G, and EG/2 form a right triangle. Graphically,
The formula of the Pythagorean Theorem is
[tex]\begin{gathered} a^2+b^2=c^2 \\ \text{ Where c is the hypotenuse and} \\ a,b\text{ are the sides of the triangle} \end{gathered}[/tex]So, you have
[tex]\begin{gathered} a=16 \\ b=\frac{EG}{2} \\ c=20 \\ (16)^2+b^2=(20)^2 \\ 256+b^2=400 \\ \text{ Subtract 256 from both sides of the equation} \\ 256+b^2-256=400-256 \\ b^2=400-256 \\ b^2=144 \\ \text{ Apply square root to both sides of the equation} \\ \sqrt[]{b^2}=\sqrt[]{144} \\ b=12 \\ \text{ Then} \\ \frac{EG}{2}=12 \end{gathered}[/tex]Then, the measure of the segment EG, that is, the measure of the base of the triangle EFG is
[tex]\begin{gathered} \frac{EG}{2}=12 \\ \text{ Multiply by 2 on both sides of the equation} \\ \frac{EG}{2}\cdot2=12\cdot2 \\ EG=24 \end{gathered}[/tex]Finally, the area of triangle EFG will be
[tex]\begin{gathered} b=24\operatorname{cm} \\ h=16\operatorname{cm} \\ A=\frac{b\cdot h}{2} \\ A=\frac{24\operatorname{cm}\cdot16\operatorname{cm}}{2} \\ A=\frac{384\operatorname{cm}^2}{2} \\ A=192\operatorname{cm}^2\text{ } \end{gathered}[/tex]Therefore, the area of the triangle EFG is 192 square centimeters.

5. Devon is considering taking out a 7,000 loan. He went to two banks, Stevenson Trust Company offered him an 8-year loan with an interest rate of 8.6%First National Bank offered him a 5-year loan with an interest of 10%Which loan will have the lower interest over its lifetime ?
The loan from National bank will have lower interest over its lifetime.
Interest is the additional payment made by a borrower or deposit-taking financial institution to a lender or depositor at a predetermined rate over and above the principal sum (the amount borrowed).
Interest differs from any fees the borrower may be required to pay to the lender or another party.Interest contrasts from a dividend, which is cash distributed to shareholders (owners) by a corporation from its profit or reserve, but not at a predefined rate or proportionally; rather, it is a portion of the reward gained by risk-taking businessmen when revenue is made that surpasses all expenditures.The principal or the amount to be taken loan is $7000.
Let us consider each bank and find the interest to be owed from the loan.
Stevension trust :
Rate = 8.6% = 0.086
time = 8 years
Interest = principal × time × rate = 7000 × 8 × 0.086 = $ 4816
First national bank :
Rate = 10% = 0.1
Time = 5 years
Interest = 7000 × 5 × 0.1 = $3500
Hence the loan from national bank will have lower interest over its lifetime.

pants cost $15.99 each, write an inequality that represents all
possible combinations of x shirts and y pants.
An inequality that represents all possible combinations of x shirts and y pants is (12.99x + 15.99y) ≤ 125.
What are Inequalities?An inequality in algebra is a mathematical expression that uses the inequality symbol to show the relationship between two expressions. The expressions on either side of an inequality symbol are not equal. When the symbols ">," <","≤ ", or "≥" are used to connect two real numbers or algebraic expressions, the relationship is referred to as an inequality.Given:
Cost of each shirt = $12.99
Cost of each pant = $15.99
Let's assume the number of shirts is x and the number of pants is y.
Total cost of x shirts = $12.99x
Total cost of y pants = $15.99y
Total cost = $(12.99x+15.99y).
Now, she does not want to spend more than $125 which means she can spend equal to or less than 125 dollars.

Ryan has two jobs. He earns $9 per hour for x hours babysitting his cousins and he earns $18 per hour for y hours working at the coffee shop. Ryan will work both jobs. He is able to work no more than 10 hours a week, due to school commitments. Ryan wants to earn at least $72 a week, working a combination of both jobs. A write a system of inequalities that can be used to represent the situation.B. Graph these inequalities C. Determine and state one combination of hours that will allow Ryan to earn at least $72 per week while working no more than 10 hours
Let x and y be the number of hours Ryan works on each job respectively. He can work no more that 10 hours a week, it means that the sum of x and y must be less than or equal to 10:
[tex]x+y\le10[/tex]He also need to earn at least $72 a week, which means that the sum of 9 times x and 18 times y must be greater than or equal to 72:
[tex]9x+18y\ge72[/tex]The system of inequalities is:
[tex]\begin{gathered} x+y\le10 \\ 9x+18y\ge72 \end{gathered}[/tex]To graph these inequalities, we have to graph the boundary lines which are x+y=10 and 9x+18y=72, and then shade the region depending on the inequality. For the first inequality which is a less than or equal to, the shaded region must be under the boundary line (which is a continuous line) and for the second one, the shaded region must be above the boundary line (which is also continous).
In this case we only can take the solutions that have positive values of x and y, since Ryan can't work a negative number of hours. For example, one combination that will allow Ryan reach his goal is 5 hours as babysitter and 5 hours at the coffee shop.
