Answer:
16/49
Step-by-step explanation:
you have a numerator of four
4 times 4 = 16
and a denominator of 7
7 times 7 = 49
16/49
You need to subtract 25 by 18
Only 3 and 9 are both the subset of odd numbers and the subset of multiples of 3.
Answer:
180cm^3
Step-by-step explanation:
All you have to do is multiply everything together to get the volume. l x w x h
T_n = 3 * T_(n-1)
Long way (always works!)
T_5 = 3*T_4,
T_4 = 3*T_3
T_3 = 3*T_2
T_2 = 3*T_1
T_5 = 3*3*3*3*T_1 = 81*T_1 = 81*8 = 648!
Short way (sometimes it works!)
T_n = 3^(n-1) * T_1 (this case is a geometric series of ratio-=3)
T_5 = 3^4*8 = 648
