American eagle is having a sale in which all jeans are priced $20 each. the sales tax is 5%. if tammy buys n pairs of jeans during this sale, the total cost of her purchase will be 20n + 0.05(20n). what does 0.05(20n) in this context represent? a. the expression 0.05(20n) represents the cost of tammy’s purchase before tax. b. the expression 0.05(20n) represents the total tax on tammy’s purchase. c. the expression 0.05(20n) represents the total cost of tammy’s purchase. d. the expression 0.05(20n) represents the price of each pair of jeans.

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°

6 and 24

step-by-step explanation:

6 x 4 = 24

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
