Answer:
20 questions.
Step-by-step explanation:
Let x be the number of questions on the quiz.
85
% means 85 out of 100 (or 85/
100 )
85/
100
= 3/x
--->100-85=15
--->15/3=5
--->100/5=20
Meaning each question was worth 5% and there were 20 questions.

Answer:
In fifteen years, Alexis would have 9200. In twenty years she would have 9600
Step-by-step explanation:
10% for interest of 8000= 80.
80 (interest for one year) * 15 (fifteen years)= 1200
1200 plus the original amount is 9200.
80 (interest for one year) * 20 ( twenty years)= 1600
1600 plus the original amount is 9600
Answer:
0.36
Step-by-step explanation:
A= K/B^2
K= A × B^2
K= 1 × 3^2
K= 1×9
K= 9
Therefore if B is 5 then A can be calculated as follows.
K= A × B^2
9= A × 5^2
9= A × 25
9= 25A
A= 9/25
A= 0.36
Hence A is 0.36
