I asssume we want to find the original price
so marked up 50% means if original price=100, then marked up price=50+100=150%
so
36.76=150%
hack, since 150=3 times 50 and 2 times 50=100, divide 36.76 by 3 then mutiply by 2
36.76=150%
divide both sides by 3
12.25333333333=50%
multiply both sides by 2
24.5=100%
original price=$24.50
Answer:
1/2
Step-by-step explanation:
(1,-5)(3,-17)
slope = (-17 - (-5) / (3 - 1) = - 12/2 = - 6
y = mx + b
slope(m) = -6
use either of ur points...(1,-5)...x = 1 and y = -5
now we sub and find b, the y int
-5 = -6(1) + b
-5 = -6 + b
-5 + 6 = b
1 = b
so ur equation is : y = -6x + 1....or 6x + y = 1
Hope this helps!
Since we are given with the three sides of the triangle and asked to determine the angle, we can use the cosine law.
"The bread-enclosed convenience food known as the "sandwich" is attributed to John Montagu, fourth Earl of Sandwich (1718-1792), a British statesman and notorious profligate and gambler, who is said to be the inventor of this type of food so that he would not have to leave his gaming table to take supper.
