Maggie has a piece of string that is 60 m she then divides those strings into 2 pieces in the ratio of 7:8. what is the length of the longer string doubled?
let the length be x
then (7x+8x)/15= 60
get x
lenght is 15x
your answer is 2*15x=30x

Is 4/9 greater than 1/3?
that is where lcm comes handy
lcm of 9 and 3 is 9
multiply it to both the numbers
4/9 *9 = 4
1/3*9 = 3
so 4/9 is greater
can u give me the solution for -
the value of cube root of 64 raised to the power of -2
cube root of 64 is 4
4 raised to power to -2 = 1/16
thanks. b would be 2/3x or just 2/3 without the x?
2/3x
I don't understand how you could expand (1+2/3x)^n if you don't have the value of n. Even if I do plug in the formula (a^n+(n,1) a^n-1b) How do I get n alone?

check this out
range of 1/3-cos4x
cos 4x max value is +1
so 1/3-1=-2/3
cos 4x min value is -1
so 1/3+1=4/3
so range is
