Half of the bigger one so the little one is 900
378 is the number since it is found to be divisible by not only 7 but also 3.
2 just divide 6 and 3 give you 2 now 2 x 4 give you 8 8 kilograms is 4 hours
Right triangle 30 60 90
short leg = 1/2 hypo = 4√2 / 2 = 2√2
so x = 2√2
long leg = short leg times √3 = 2√2 * √3 = 2√6
so y = 2√6
answer C.
x = 2√2 ; y = 2√6
