Trip expenditure = t.
\(t<4200+\dfrac{6000-4200}{91}\) Inequation.
Area = 72 m^2.
OR
Area = (x)(x+6) = x^2 + 6x.
Therefore
x^2 + 6x = 72
x^2 + 6x - 72 = 0 <---- That became a quadratic.
(x+12)(x-6) = 0
x = -12 (rejected) OR x = 6
Therefore length = x = 6, and width = x + 6 = 6 + 6 = 12.
gimme the stars :)
-14 + 2x = 6
-14 +2x + 14 = 6 + 14
2x = 20
x = 10
\(-\frac{4}{5}\times \frac{9}{5}\\ =-\frac{4\times 9}{5\times5}\\ = -\frac{36}{25}\)
4/10 + 15/10 = (4+15)/10 = 19/10 = 1 9/10
\(\sqrt{-9}\)= 3i according to the calculator on this site, and it is correct.
2/3 = 66 2/3 % approximated as 0.67 or \(0.\overbrace{666666.....6}^{\infty}\)
\(H_2O_2\rightarrow H_2O+O_2\\ 2H_2O_2\rightarrow 2H_2O + O_2\)
Does that mean every 2 molecules of hydrogen peroxide will break down into 2 molucules of water and 1 molecule of oxygen gas?
Sorry for only knowing how to balance an equation LOL
30% x 3360
= 30/100 x 3360 <-- def. of percentages.
= 3/10 x 3360
= 3 x 336
= 1008
