Hope it will help :)
Answer:
2.5%
Step-by-step explanation:
% = (faulty batteries / total batteries) x 100
= (3/120) x 100
= 0.025 x 100
= 2.5
Answer:
The student did not divide 5 into 25 but subtracted 25 from both sides. It looks like the student then moved the -5 over to the other side somehow.
To solve this problem you must apply the proccedure shown below:
1. You have that the ratio of the tangent function is:
tan(angle)=opposite/adjacent
2. Keeping this on mind, you have:
tan(A)=12/5
Therefore, the answer is:
tan(A)=12/5
(3x-9/x+) × (2x+8/x^2-x-6)
= 6/(x+2)
