**English**

whay are the effective study techniques
*August 31, 2014*

**maths**

principal=Rs.3,750,rate of interest=8%p.a,time=2years
*January 3, 2012*

**Algebra**

Use the sqaure root property to solve the equation. 7x^2-4=0

**Algebra**

just distribute, then combine like terms: if it helps break it down: 4(7x),4(-1)=3(2x),3(1)=-4(x),-4(6) so then you have: 28x-4=6x+3-4x-24, then just combine like terms, you goal is to isolate the variable

**Math**

7(x-2)+3(x+2)=5(x-6) 7x-14+3x+6=5x-30 -distribute 10x-14+6=5x-30 -combine like terms 10x-8=5x-30 -get x's on 1 side 5x-8=-30 5x=-22 -isolate the x x=-22/5

**Algebra (I think)**

40(x)+13(1.5x)=833 =40x+20x=833 =60x=833 x needs to be isolated, so divide 60 from 833 x=833/60 x=14 hourly rate =$14.00 overtime rate=1.5(14)=$21.00

**Physics**

You just use the equation vf=vi+at. Your initial velocity would be zero since it's starting from rest, your acceleration in this case would be 4.8 m/s^2, and your time would be 2.3 seconds. Your answer will be 11.04 m/s.

**Chemistry- college**

A: you can either look at the properties table or use -74.9kJ/mol= x + 92.3 kJ/mol and solve for x which is -167.16...... juse the equation deltaH= Sum deltaH of products - sum deltaH of reactants idk how to do B yet

**chemistry**

if the mass of protons are halved and that of neutrons doubled to that of the actual values, what percentage change would have been found in the atomic mass of chromium whose actual atomic mass is 52.

**chemistry**

use the equation M1V1 = M2V2
