Answer:
Jada used 1/2 of the pancake mix in the box
Step-by-step explanation:
we know that
-----> represent the 100% of the box
so
by proportion
Find what fraction represent 
First convert mixed number to an improper fraction
Convert the percentage into fraction
We can use the is/of=p/100 method for this problem. Since it's 15% off, this would mean that the bill is 85% of what it was initially. Plug the values into the is/of=p/100 formula.
36.72/x = 85/100
Solve for x.
x=36.72/0.85
x=43.2
So, the bill was $43.20 before applying the voucher discount of 15% off.

Answer:
x = sqrt(17)
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2
Let the unknown side be x
8^2 + x^2 = 9^2
64 + x^2 = 81
Subtract 64 from each side
x^2 = 81-64
x^2 =17
Taking the square root of each side
x = sqrt(17)
