Question:
Solution:
To write an equation for a line, we need a point and direction of the line. The direction is represented by the slope. Now, the slope-intercept form of a line is given by the following equation:
\(y\text{ = mx+b}\)where m is the slope of a line and b is the y-intercept. Now, to find the slope m of this line we apply the following formula:
\(m\text{ = }\frac{Y2-Y1}{X2-X1}\)where (X1,Y1) and (X2,Y2) are points on the line. In this case, we can take the points:
(X1,Y1)= (3,4)
(X2,Y2)=(5,-7)
thus, the slope of the line KL is:
\(m\text{ = }\frac{Y2-Y1}{X2-X1}=\text{ }\frac{-7-4}{5-3}\text{ =}\frac{-11}{2}=\text{ -}\frac{11}{2}\)thus, the provisional equation of the line is:
\(y\text{ = -}\frac{11}{2}x+b\)now, to find b, we can take any point on the line and replace it in the above equation; then, solve for b. For example, we can take (x,y)=(3,4), thus:
\(4\text{ = -}\frac{11}{2}(3)+b\)this is equivalent to:
\(4\text{ = -}\frac{33}{2}+b\)solving for b, we get:
\(b=\text{ 4+}\frac{33}{2}=\frac{(2)(4)+33}{2}=\frac{8+33}{2}=\frac{41}{2}\)then
\(b=\text{ }\frac{41}{2}\)we can conclude that the slope-intercept form of the line KL is:
\(y\text{ = -}\frac{11}{2}x+\frac{41}{2}\)where x varies on the interval:
\(\lbrack3,5\rbrack\)goes through the points (6,2) and (5, 4)

One aircraft has a capacity of 64 more seats than a second
aircraft. A third aircraft has 152 seats less than twice the seating
capacity of the second aircraft. If their total number of seats is
1900, find the number of seats for each aircraft.
Therefore, the number of seats for each aircraft is 752, 688, and 1224.
Define Unitary method.The unitary method is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.
What is multiplication?Multiplying in math is the same as adding equal groups. The number of items in the group grows as we multiply. Parts of a multiplication issue include the product, the two factors, and the product. The components in the multiplication problem 6 x 9 = 54 are the numbers 6 and 9, and the result is the number 54.
Let x be the number of seats for the second aircraft.
The first aircraft has x + 64 seats.
The third aircraft has 2x - 152 seats.
The total number of seats for all aircraft is x + (x + 64) + (2x - 152) = 1900.
Therefore, 3x = 2064, so x = 688.
The first aircraft has 688 + 64 = 752 seats.
The third aircraft has 2(688) - 152 = 1224 seats.

Use the Law of Sines to solve the triangle. Round your answers to two decimal places. (Let b = 5.1.)
Given:-
An image with triangle.
To find:-
The value of B,a,c.
So the laws of sines are,
\(\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}\)So now we substitute the known values. we get,
\(\frac{\sin16}{a}=\frac{\sin B}{5.1}=\frac{\sin125}{c}\)Now we find the value of B,
Since the sum of angles of the triangle is 180. we get,
\(\begin{gathered} A+B+C=180 \\ 16+B+125=180 \\ B+141=180 \\ B=180-141 \\ B=39 \end{gathered}\)So substituting the value we get,
\(\frac{\sin16}{a}=\frac{\sin 39}{5.1}=\frac{\sin125}{c}\)Now we find the value of a. we get,
\(\begin{gathered} \frac{\sin16}{a}=\frac{\sin 39}{5.1} \\ \frac{0.2756}{a}=\frac{0.6293}{5.1} \\ a=\frac{0.2756\times5.1}{0.6293} \\ a=2.2335 \end{gathered}\)Now we find c. we get,
\(\frac{0.2756}{2.2335}=\frac{\sin 125}{c}\)So

ssume all information in example 1 above and the following additional information: Actual data for job 201 is give is given belowActual shirts completed for job 201………………2,000 shirtsActual direct material cost used………………...$30,000Actual direct cost incurred……………………...$20,000Actual direct labor hours used…………………. 400 hoursActual machine hours…………………………. 240 hoursInstruction: compute the applied factory overhead and determine the total cost of job 201 under each of the five bases. A) Physical output as allocation baseDirect materials cost as allocation base Direct labor cost as allocation base Direct labor hours as allocation baseMachine hours as allocation base
The applied overhead cost for job 201 is $36,000 and total cost for job 201 under direct materials cost as allocation base is $86,000.
Allocation base is a technique utilized in accounting to designate the cost of something to its use or product to recognize the price of the finished product.
Example provides the total overhead cost at $120,000 for the period, the base data of $100,000 direct material cost and 500 direct labor hours. The base data are used to calculate the predetermined factory overhead rate, which is used to apply overhead costs to work in progress.
The predetermined factory overhead rate is calculated by dividing the total overhead cost for the period by the base data. The predetermined factory overhead rate is multiplied by the actual activity in the allocation base to obtain the applied overhead cost.
Direct materials cost as allocation base $30,000 is the actual direct material cost used in job 201. The predetermined factory overhead rate is calculated by dividing the total overhead cost for the period by the direct material cost, which is $120,000/$100,000=120%.
The applied overhead cost for job 201 is $30,000*120% = $36,000.
Total cost for job 201 under direct materials cost as allocation base is $30,000+$20,000+$36,000 = $86,000.
-Direct labor cost as allocation base:
The actual direct labor cost used in job 201 is $20,000. The predetermined factory overhead rate is calculated by dividing the total overhead cost for the period by the direct labor cost, which is $120,000/$100,000=120%.
The applied overhead cost for job 201 is $20,000*120% = $24,000.
Total cost for job 201 under direct labor cost as allocation base is $30,000+$20,000+$24,000 = $74,000.
-Direct labor hours as allocation base:
The actual direct labor hours used in job 201 is 400 hours.
The predetermined factory overhead rate is calculated by dividing the total overhead cost for the period by the direct labor hours, which is $120,000/500 hours = $240 per hour.The applied overhead cost for job 201 is $240*400 hours = $96,000.
Total cost for job 201 under direct labor hours as allocation base is $30,000+$20,000+$96,000 = $146,000.
-Physical output as allocation base: The actual output in units completed for job 201 is 2,000 shirts.
The predetermined factory overhead rate is calculated by dividing the total overhead cost for the period by the output in units, which is $120,000/10,000 units = $12 per unit.
The applied overhead cost for job 201 is $12*2,000 units = $24,000.Total cost for job 201 under physical output as allocation base is $30,000+$20,000+$24,000 = $74,000.
-Machine hours as allocation base: The actual machine hours used in job 201 is 240 hours.
The predetermined factory overhead rate is calculated by dividing the total overhead cost for the period by the machine hours, which is $120,000/5,000 hours = $24 per hour.
The applied overhead cost for job 201 is $24*240 hours = $5,760.
Total cost for job 201 under machine hours as allocation base is $30,000+$20,000+$5,760 = $55,760.

Simplify i) ( x-y )( x−y )( x−y )
The simplified expression for ( x - y ) ( x - y ) ( x - y ) is x³ - x²y - xy² + y³.
To simplify ( x - y ) ( x - y ) ( x - y ), we can expand the expression using the distributive property of multiplication. We can also simplify the expression by combining like terms.
In using the distributive property of multiplication, we multiply each term in the first set of parentheses by each term in the second set of parentheses. This gives us:( x - y ) ( x - y ) ( x - y ) = ( x(x - y) - y(x - y) ) ( x - y )= ( x² - xy - xy + y² ) ( x - y )= ( x² - 2xy + y² ) ( x - y )
Now we can further simplify the expression by combining like terms. We can use the difference of squares formula to simplify the second set of parentheses.( x² - 2xy + y² ) ( x - y ) = ( x - y ) ( x - y )²= ( x - y ) ( x² - 2xy + y² )= x³ - x²y - 2xy² + xy² - xy² + y³= x³ - x²y - xy² + y³
Therefore, the simplified expression is x³ - x²y - xy² + y³.
Summary: To simplify ( x - y ) ( x - y ) ( x - y ), we expand the expression using the distributive property of multiplication. We simplify the expression by combining like terms. We use the difference of squares formula to simplify the second set of parentheses. Finally, we simplify the expression further by combining like terms.

Reuben made a shirt using 7/8yards of red fabric and 1/4yards of yellow fabric. How many more yards of red fabric did Reuben use?
Answer and Step-by-step explanation:
To find out how many more yards of red fabric Reuben used, we need to subtract the amount of yellow fabric from the amount of red fabric. Since the two fractions have different denominators, we need to find a common denominator before subtracting them. The least common multiple of 8 and 4 is 8, so we can rewrite both fractions with a denominator of 8:
7/8 - 1/4 = 7/8 - (1/4) * (2/2) = 7/8 - 2/8 = (7 - 2)/8 = 5/8
So, Reuben used 5/8 yards more red fabric than yellow fabric.
