Amy's mistake was she took the angles as alternate interior angles, rather they form supplementary angles. The measure of both angles are 118 and 62.
What are alternate interior angles?The alternate interior angles theorem states that if a transversal connects two parallel lines, the alternate interior angles are identical in size. If we know the measure of the corresponding alternate interior angle, we may use this theorem to determine the measure of the alternate interior angle.
As per the given question,
both angles are not alternate interior angles,
rather both of the angles are supplementary angles.
This means that both form the sum of 180
⇒ 3n - 47 + n + 7 = 180
⇒ 4n - 40 = 180
⇒ 4n = 220
⇒ n = 55
∴ The measure of both angles will be 3n - 47 = 118 and n + 7 = 62

Evan's parents budget 15% of their monthly disposable income of $5,200 for clothes. They budget 25% of the 15% budget amount for Evan's clothing, Evan buys his ownclothes above the budgeted amount. Evan had the following estimated totals for the six-month period from March through August: clothes = $1,278; repairs and alterations =$75; and dry cleaning = $70. How much will Evan have to pay out of his own pocket?$253.00$250.25$245,50$241.75None of these choices are correct.
Answers
First find the 15% of $5,200 to know how money they spend on clothing.
(15*5,200)/ 100 = $780
They budget 25% of the 15% budget amount for Evan's clothing
(25*780)/100 = 195 for each month
195*6 = $1,170 for the six-month period
The estimated totals for the six-month period is
$1,278 + $75 +$70 = $1,423
Make the subtraction between the six month period and the estimated totals for the six-month period:
$1,170 - $1,423 =-253
$253.00 is the amount that Evan have to paoy out of his own pocket.

f(x) = (x - 2)(x + 6)
The above equation is a quadratic function.
Next, we plot the equation on a graph (see attachment)
Set x = 0 to determine the y-intercept
y-intercept = (0 - 2)(x + 6)
y-intercept = -12
Expand the function to determine the symmetry axis
f(x) = x^2 - 2x + 6x - 12
Differentiate and set to 0
2x - 2 + 6 = 0
This gives
x = -2 --- axis of symmetry
Substitute x = -2 in the function to calculate the vertex/Min/Max
f(-2) = (-2 - 2)(-2 + 6)
f(-2) = -16
This means that

Plan 1 is more economical than plan 2. 0.04y + 11 > 30
What is inequality?A statement of an order relationship between two numbers or algebraic expressions (greater than, greater than or equal to, less than, or less than or equal to). The expression 5x 4 > 2x + 3 resembles an equation, but the equals sign has been replaced by an arrowhead. It's an example of inequity. This means that the left part, 5x 4, is greater than the right part, 2x + 3. In mathematics, an inequality depicts the relationship between two non-equal values in an algebraic expression. Inequality signs can indicate that one of the two variables is greater than, greater than or equal to, less than, or less than or equal to another value.Therefore,
We can point to the digit of calls as "y"
From plan 1, the Total monthly charge is $30
From plan 2, the Fix charge is $11 with $0.04 per call
We can express the cost of the "y" call as( $0.04y)
From plan2, The monthly charge can be expressed as (0.04x + 11)
a) Use an imbalance to find the number of monthly calls for which Plan 1 is more economical than Plan 2.
Here, Plan 1 is more economical than plan 2.
0.04y + 11 > 30
Multiply both sides by 100
0.04y . 100 + 11.100 > 30.100
Refine
4 y+1100>3000$
Subtract 1100 from both sides

A loan occurs when one or more individuals, businesses, or other entities lend money to additional individuals, businesses, or other entities.
A loan is obtained, and the recipient, or borrower, is typically liable for both the principal borrowed as well as interest payments until the debt is repaid.The principle amount borrowed, the interest rate the lender is charging, and the due date for repayment are often disclosed in the promissory note used to demonstrate the obligation. The subject asset(s) are temporarily divided between the borrower and the lender when a loan is issued.Interest on the loan = 30000 × 0.18 × 7 = $37800
Total amount to be paid = $ 30000 + $ 37800 = $67800

Step-by-step explanation:
6% of 368 is 22.08.
5 days = 6% x 5 = 30%.
30% of 368 = 110.4
110.4 + 368 = 478.4
