Answer:
about 0.0927 seconds
Step-by-step explanation:
Put the given information into the given formula and solve for the remaining variable. It is a linear equation, solved in the usual way.
ln(0.430/0.750) = -7.50t/1.25 . . . substitute the given information
-ln(43/75)/6 = t ≈ 0.092714 . . . . . divide by the coefficient of t
Rounded to 3 significant figures, the time is 0.0927 seconds.
Of means multiply, so we are going to multiply. Step 1: Make 15% a decimal:

. Step 2: Multiply 0.15 by $25.00:

. Your answer is

. Hoped I helped. :)
You have to change each groschen to be equal to Y and then input it into a graphing calculator to get the points
Let's raise the exponent three on both sides of the equation.
1/x^2 = (x^m)^3
1/x^2 = x^(3m)
1 = x^2.x^(3m)
1 = x^(2+3m)
X^(2+3m) = 1
For this to be true:
2+3m = 0
3m = -2
m = -2/3
Its because when you fold the paper its makes it half so thats why it would be like that.
