Answer:
1)
2)
3)
4)Rs.36 000
Step-by-step explanation:
1)1/3+1/4=4/12+3/12
=7/12
2)remaining=12/12-7/12
=5/12
other expenses=5/12*3/5
=1/4
3)total=7/12+1/4
=7/12+3/12
=10/12
=5/6
remaining=6/6-5/6
=1/6
fraction of the salary=1/6*2
=2/12
4)1/6=rs.6000
6/6=rs,36 000
The ratio to this problem is 750:216
The standard form of the quadratic equation is ax^2 + bx + c. In vertex form, it's y = a(x – h)2 + k.
The graph of a quadratic equation is a parabola, which looks like a u. If <em>a</em> is negative then it's an upside down u.
You just need to plug those expressions inside the formula: it doesn't matter if they're expressions involving a variable instead of plain numbers: the formula becomes

If you want, you can simplify it by expanding the square and then multiply the two parenthesis:
