60% of 20 is (0.6 x 20) = 12 passes
There are a further 30 quizzes remaining (50 total during the year minus 20 already written)
80% of 30 is (0.8 x 30) = 24 passes
The student has passed (12 + 24) = 36 quizzes out of 50 total, giving an overall pass percentage of ((36 / 50) x 100)) = 72%.
Answer:
Step-by-step explanation:
Standard form for a circle is:
(h, k) is the center r is the radius
Answer:
vol of cube = 10 x 10 x 10 = 1000
vol of sphere = 4/3πr³ = 4/3 x 3.14 x 1000 = 4186.666
4186.666 - 1000 = 3186.666
I'm pretty sure this isn't the ans but I think the top part is right
If 4x+0=12, then x will be 3.
