A perfect score on a test with 25 questions is 100.
Each question is worth 4 points.
=> 25 * 4 points = 100 points.
Fred got a score of 80 on the tes.
We need to write a division sentence usingnegative numbers where the quotient represents the number of questions Fred answered incorrectly
=> 100 - 80 = 20 points.
=> 20 / 4 points = 5 questions
Answer:
what are the statements we pick from?
Step-by-step explanation:
most likely look out for angles and lengths that go against the established ratio
Using the property of inverse,
, we can extend the given table
x f(x) f^(-1)(f(x))
-1 1 -1
2 3 2
3 6 3
5 7 5
7 8 7
Step-by-step explanation:
the volume of :
cone = ⅓π.r².r= ⅓π.r³
cylinder = π.r²r= π.r³
Sphere = 4/3 π.r³
for r = 9 in =>
the volume of:
14. cone = ⅓.π.9³= ⅓π × 729 = 243π in³
15. cylinder = π.9³ = 729π in³
16. Sphere = 4/3 π.9³ = 972π in³
17. the volume ratio among cone, cylinder and Sphere is : ⅓ : 1 : 4/3 =
1 : 3 : 4
