If you have 49 questions on a test what score must you get to pass the test?

1 answer:

7 0

Well, on every test I have at a school and I believe most schools do this. You need at leasr 80% to pass. But to pass you'd most likely need 80% or 70%. But if you get an 80% you'll be sure to pass! I hope this helps you!

Answer:

y = 1/3

Step-by-step explanation:

Circle Center Formula: (x - h)² + (y - k)² = r²

(h, k) is center
r is radius

Step-by-step explanation:

Step 1: Define

Identify

(h, k) = (8, 10)

r = 6

Step 2: Find Equation

Substitute in variables [Center Circle Formula]: (x - 8)² + (y - 10)² = 6²
Evaluate exponents: (x - 8)² + (y - 10)² = 36
