original -.20* original = sales price

original (1-.2) =sales price

original*.8 = sales price

total amount = sales price + sales price*.08

total amount = sales price + sales price*.08

total amount = sales price (1+.08)

total amount = sales price (1.08)

replace original price with p


.8 p =sales price


total amount = .8p(1.08)

total amount = .864p

The figure shows two parallel lines KL and NO cut by the transversals KO and LN.
Sever21 [200]

Answer:

(A)  

Step-by-step explanation:

From the given figure, we have to prove whether the two given triangles are congruent or similar.

Thus, From the figure, ∠3=∠4 (Vertically opposite angles)

Since, KL and NO are parallel lines and KO and LN are transversals, then

measure angle 1= measure angle 5 that is ∠1=∠5(Alternate angles).

Thus, by AA similarity rule, ΔKLM is similar to ΔONM.

Thus, Option A that is Triangle KLM is similar to triangle ONM because measure of angle 3 equals measure of angle 4 and measure of angle 1 equals measure of angle 5 is correct.

Which option accurately describes a scenario in which a tortoise experiences a displacement of 10 m south? A tortoise starts at
Ahat [919]

Answer:

A tortoise starts at a position of 0 m. It moves 10 m west,10 m east, and then 10 m south.

Step-by-step explanation:

Let's assume southern and eastern movement as positive and northern and western movement as negative. Since we want the displacement, starting position should not be considered.

1-) A tortoise starts at a position of 3 m south. It moves 4 m east, 2 m west, and then 3 m north.

S = -3m

E = 4 - 2 =2m

2-) A tortoise starts at a position of 0 m. It moves 10 m west,10 m east, and then 10 m south.

S= 10m

E= 10 - 10 = 0m

3-) A tortoise starts at a position of 2 m north. It moves 4 m west and then 7 m south.

S= 7m

E= -4m

4-) A tortoise starts at a position of 0 m. It moves 10 m west, 5 m east, and then 5 m south.

S= 5m

E= 5 - 10 = -5m

Analyzing all of the previous scenarios, only one presents a 10 m southern displacement, and that is when the tortoise starts at a position of 0 m. It moves 10 m west,10 m east, and then 10 m south.

Find the missing angle thank you
Maksim231197 [3]
Straight lines will always add up to 180 degrees, so the angle that is missing here is supplementary to the other angle(adds up with the other angle to get 180) so we take 79 away from 180 and get 101 degrees
