The correct answer should 4% because the ratio is 3 out of 75 which would leave 72 non-defective bulbs. So your answer is 4%
Let the total ribbon Zoe had was x feet.
Out of x feet, she used 3/8 part of it.
Hence,
3/8 part of the original ribbon is equal to 9 feet.
Hence, we get
=> Multiply 8 on both sides.
Divide both sides by 3
Zoe had 24 feet of ribbon in starting... Answer
Simplifying -2x + -3y = -7
Solving -2x + -3y = -7
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation. -2x + -3y + 3y = -7 + 3y
Combine like terms: -3y + 3y = 0 -2x + 0 = -7 + 3y -2x = -7 + 3y
Divide each side by '-2'. x = 3.5 + -1.5y Simplifying x = 3.5 + -1.5y
Answer:
22.2 ft²
Step-by-step explanation:
The area (A) of a sector is calculated as
A = area of circle × fraction of circle
= πr² ×
= π × 7.13² ×
= ≈ 22.2 ft² ( nearest tenth )
