The composition of two isometries is an isometry.

Proof:

Let T1 and T2 be isometries. T1(A) = A' and T1(B) = B'. Therefore by isometry T1, AB = A'B'

T2(A) = A'' and T2(B) = B''. Therefore by isometry T2, AB = A''B''

T2 º T1 = T2(T1(A)) = T2(A') = A'''. T2 º T1 = T2(T1(A)) = T2(B') = B'''. Therefore under composition AB = A'''B''' and distance is preserved.

The inverse of an isometry is an isometry.

Proof:

Given T and isometry. This means T(A) = A' and T(B) = B' with AB = A'B'

The inverse of T, T⁻¹maps A' to A and B' to B, so A'B' maps to AB.

But A'B' = AB and so the inverse is an isometry

After reflecting the quadrilateral EFGH across the line y = 2, the x-coordinates of the corresponding points in the image and the preimage will be the same.

Generally,  Reflection is an isometry, which means that it preserves distance and angles. Therefore, the x-coordinates of the points in the image and the preimage will not be changed by the reflection. The y-coordinates will change since the reflection flips the points over the line of reflection.

For example, if quadrilateral EFGH has a vertex at (x, y), then the corresponding vertex in the image will be at (x, 2 - y). The x-coordinate remains the same, but the y-coordinate is reflected across the line y = 2.

The percentage of having a probability of a non-vowel letter is 44%

Probability is the measure of the likelihood that an event will occur in a given set of circumstances. It is a quantifiable measure of the chance of something happening. Probability is expressed as a number between 0 and 1 (or 0% to 100%) where the higher the number, the more likely the event is to occur.

The probability to select a vowel letter is = 15 + 22 + 11 + 6 + 2 = 56%

The probability of selecting any vowel is 56%

In the English alphabet, we have 26 letters and 5 vowel letters.

The probability of not having a vowel letter is calculated as;

26 - 5 = 21

P = 21 / 28

In percentage, we can simply say the probability of having a non-vowel is 100 - 56 = 44

Answer:

Point slope: y - 115 = 2(x -30)

Slope intercept: y = 2x + 55

Step-by-step explanation:

I choice the first point to write the equation in the point slope form of a line.

(30,115)

Slope is the change in y over the change in x.  I see that the y's are increasing by 10, while the x's are increasing by 5

10/5 = 2

The slope is 2

y = y = m( x + x)

y - 115 = 2(x - 30)

Slope intercept form of a line

We already found the slope to be 2.  Use the slope and the point (30,115) to find x

y = mx + b

115 = 2(30) + b

115 = 30 + b    Subtract 30 from both sides

55 = b

y = 2x + 55

Answer: Barry's Swimwear sold a greater fraction of the bathing suits in stock as long as the store had fewer than 72 bathing suits in stock.

Step-by-step explanation:

Barry's Swimwear sold 15 out of an unknown number of bathing suits in stock, so we can express this fraction as 15/x, where x is the total number of bathing suits in stock at Barry's Swimwear. Similarly, Philip's Sun Wear sold 5 out of 72 bathing suits in stock, so we can express this fraction as 5/72.

To compare these two fractions, we need to express them with a common denominator. One way to do this is to find the least common multiple of the two denominators, which in this case is 72. To express 15/x with a denominator of 72, we can multiply both the numerator and the denominator by a factor of 72/x. This results in the fraction 15*(72/x)/72 = 15/x. Similarly, we can express 5/72 with a denominator of 72 by multiplying both the numerator and the denominator by a factor of 72/72, which results in the fraction 5*(72/72)/72 = 5/72.

Now that we have both fractions expressed with a common denominator of 72, we can compare them directly. 15/x is greater than 5/72 as long as x is less than 72. This means that Barry's Swimwear sold a greater fraction of the bathing suits in stock as long as the store had fewer than 72 bathing suits in stock.

Cumulative markup percent for department at the end  is 23.1%.

The men's furnishing department had an opening inventory of $168,000 at cost  with a markup of 48.5%

Cumulative markup is  the difference between the total wholesale cost and total retail price of all merchandise handled during a given period of time.

cumulative markup dollars are the total markup dollars on all merchandise for a selected selling period. To calculate cumulative markup dollars and cumulative markup percent, the following formulas are utilized by the retailer:

Cumulative Markup $ = Total Retail $ - Total Cost $

Cumulative Markup % = Cumulative Markup $ ÷ Cumulative Retail $

Steps for calculating cumulative markup percentage for the specified period of time:

Step 1. Calculate the unknown retail value for either opening inventory or purchases.

Step 2. Calculate total retail of opening inventory and purchases.

Step 3. Calculate the unknown cost value for either opening inventory or purchases.

Step 4. Calculate total cost of opening inventory and purchases.

Step 5. Calculate total markup dollars.

Step 6. Calculate cumulative markup percent for the specified period of time.

For opening inventory

retail = $168,000

cost = 168,000*48.5/100 = $81480

For purchases

retail = 80,000*52.5/100 = $42000

cost  = $80,000

total retail of opening inventory and purchase =

168,000+42000 = $210000

total cost of opening inventory and purchase =

81480+80,000 = $161480

total markup = total retail - total cost

total markup  = 210000-161480 = 48520

cumulative markup percent = (total markup/ total retail)

= (48520/210000)*100

= 0.23104761904*100

=23.1%

So cumulative markup percent for department at the end  is 23.1%.

Rounded to the nearest cent, the final value of Irlene's investment at the end of the third year is $4,431.78.

A percentage of the principal, or the amount loaned, is what a lender charges a borrower as interest. The annual percentage rate, or APR, is the usual unit used to express the interest rate on a loan (APR).

To calculate the value of Irlene's investment at the end of the third year, you can use the formula for compound interest:

FV = PV * (1 + r/n)^(n*t)

Where:

FV is the future value of the investment (what you want to find)

PV is the present value of the investment (the initial amount, $3,500)

r is the annual interest rate (the rate for the third year is 5.25%)

n is the number of compounding periods per year (for the first year it was 2, for the second year it was 2, and for the third year it was 4)

t is the number of years the money is invested (3 years in this case)

Plugging the values into the formula, you get:

FV = $3,500 * (1 + 5.25%/2)^(23) * (1 + 5.25%/4)^(41)

= $3,500 * (1.0263)^6 * (1.0131)^4

The monthly take home pay if your take-home pay is calculated as 46 hours per week; is $2,606.6.

What is monthly take home pay?

The amount of money left over after taxes, benefits, and other deductions from a paycheck is known as take-home pay. It is the difference left over after subtracting all gross income deductions.

Let,

Number of hours per week = 46 weeks.

Regular hourly wage up to 40 hours = $15.90

Wage up to 40 hours = 40 x 15.90 = $636

Hours over 40 hours, wage is 1.5 times as much

Wage of hour  41 - 46 = 6 x 1.5 x 15.90 = $143.10

Total weekly wage = 636 + 143.10 = $779.10

Since 1 month = 4.345 weeks.

Therefore,

Monthly wage = Weekly wage x 4.345

                        = 777.10 x 4.345

Monthly wage = $3385.19

Now maximum and assurance = 23% of monthly wage

= 23% of 3385.19

= 0.23 x 3385.10

= $778.59

Therefore,

Monthly take home pay = Monthly wage - Tax

                                        = $3385.19 - $778.59

Monthly take home pay = $2606.6
