m + n = 10000.05m + 0.06n = 57
Solve be substitution... m+n=1000 0.05m+0.06n=57 Take one of the equation and find "m" m=1000-n substitute into the other equation 0.05(1000-n)+0.06n=57 50-0.05n+0.06n=57 50-0.01n=57 -0.01n=-7 n=700 Now you have found "n" now find "m" m=1000-n m=1000-700 m=300 m=300 and n=700
100 x 50 because if you divided 5000 by 50 it gives you 1000 so n = 1000
The formula for triangular numbers is (half of n) multiplied by (n+1). Putting in 1000 as n you get: 500 multiplied by 1001 which equals 500500. The answer is 500500.
Kgs are thousands of a gram. mGs are thousandths of a gram. this means that the conversion between mG and Kg is: ((n/1000)/1000), or n/10⁶, where n is the number which you want to convert. So, 5/10⁶ = 0.000005.
n=1 is the the lowest level there is.
n=1 a(1) = 0.001 n=2 a(2) = 0.012 n=3 a(3) = 0.144 n=4 a(4) = 1.728 n=5 a(5) = 20.736 .... n=k a(k) = (12^(k-1))/1000 let n = k+1 a(k+1) = 12^(k)/1000 12(ak) = a(k+1) 12(12^k-1)/1000 = 12^k/1000 the 12 gets absorbed here. 12^(k-1+1)/1000 = 12^k/1000 Valid for k and k+1 therefore our equation A(n) = 12^(n-1)/1000, n(greater than or equal to) 1
n = 8
15 - n when n equals 9 = 6
when n = 0 it equals -25 when n = 1 it equals -36 when n = 2 it equals -39 etc
n =33
