I think the answer is 60/t = 5
Answer:
x = 81, y = 68, z = 99
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the triangle on the left, then
x = 180 - (36 + 63) = 180 - 99 = 81
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle on the right, thus
13 + y = x , that is
13 + y = 81 ( subtract 13 from both sides )
y = 68
Consider the triangle on the right
z = 180 - (13 + y) = 180 - (13 + 68) = 180 - 81 = 99
This is how you get your answer you take 43.9 and divide it by 12.7 which gives you 3.4566 and add .52 to get 3.9766 then you multiply that number by 12.7 which gives you 50.5 so $50.5 is how much she would have originally payed.
is e^(0.25t) = 9/6 = 3/2 which is
ln(3/2) = 0.25t which is t = ln(3/2)/0.25
