Is the question how many such pieces of yarn will she have?
We have to divide: 3 yards by 1/8th yard:
3/
dividing by a fraction means multiplying by its inverse!
Solve by using the formula: c² - b² = a²
c = hypotenuse, b = leg, a = a
Plug in:
(√73)² - (8)² = a²
Simplify.
73 - 64 = a²
9 = a²
Isolate the a. Root both sides
√a² = √9
a = √9
a = √9 = √(3 * 3)
a = 3
3 ft is your answer
hope this helps

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
7×3 -4(225÷32)×2
7×3 -4(7.03)×2
21 - 8 (7.03)
21 - 56.25
= - 35.25
