The number of straight line miles traveled downriver in one hour by Lucy's boat is approximated within a linear range by 3n + 4, where n represents her fuel consumption in units/hr. Suppose that traveling x miles requires k hours at a fuel rate of 7 units/hr, but that increasing her fuel consumption by 5 units/hr would allow her to travel 40% further in 1 fewer hour. How far would she travel in k hours at a fuel rate of 10 units/hr?

what is the ans of this question? Find the value of x^3 if x^2+x+1=0.

x = cube roots of unity

@bs0409 said:

x^2+x+1=0 has imaginary roots only. No real roots....a,b,c,d,e-primea is min and e is maxa+b+c+d+e=350Find a

Please solve it .

there are two containers A and B filled with oil with different prices and their volumes are 140litres and 60 litres resp. equal quantities are drawn from both A and Bin such a manner that the oil drawn from A is oured into B and the oil drawn from B is poured in A. the price per litre becomes equal in both A and B. how much oil is drawn from each A and B? 42 , 30 , 32 , CBD

@jain4444 said:

you are not getting my point i said prime factors of 150 = prime factors of 300 and are same i.e. 2 , 3 , 5 but here prime factors of 2250 = x , 5 and 2 and prime factors of 1125 = a , b , 5 (2 is not here) so , that won't work here

how to do this one?? i m clueless...the normal logic of N/2*E(N) won't work i guess...

150 in base 3 - 12120left shift operator two times - 1201212012 in base 10 = 2 + 3 + 54 + 81 ==140
