Answer:
V=1.17 v
Step-by-step explanation:
The difference in potential between two points can be described as: potencial of the iron less potential of the zinc, that is: ![V= 0.76-(-0.41)](https://tex.z-dn.net/?f=V%3D%200.76-%28-0.41%29)
Which can be rewrite as: V= 0.76 v + 0.41 v
V=1.17 v
Given:
- Bought n items of product A at 1/5 rs each
- bought n items of product B at 1/4 rs each
He mixed the two items and sold each at 2/9 rs each.
He lost 3 rs in the above batch of articles.
Solution:
revenue = 2n* (2/9) rs = 4n/9 rs
cost = n/5+n/4 rs = n(1/5+1/4)
Profit = revenue-cost = 4n/9-n(1/5+1/4) = -3 rs
Solve for n
4n/9-n(1/5+1/4) = -3
factor out n
n(4/9-1/5-1/4)=-3
n(80-36-45)/180=-3
-n/180=-3
n=3*180=540
Total number of products bought
= n+n = 540+540 = 1080
Answer:
6/10
Step-by-step explanation:
2 groups of 3/10 =
2 × 3/10 =
6/10
-4/6
-8/12
-16/24
etc.
there are infinitely may equivalent of this fraction,
multipliy the numerator and denominator both qith the same number and you'll gey your answer.
as I did in
-4/6 = (-2/3) ×(2/2)
-8/12= (-2/3) × (4/4)
-16/24= (-2/3) × (8/8)
