4^2
Answer:
6
Step-by-step explanation:
a cube has sides of the same length hence its volume is obtain as cubed side.
we have the volume and we need the side:
![\sqrt[3]{216} =\sqrt[3]{3^{3} 2^{3} } = 3*2 = 6](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B216%7D%20%3D%5Csqrt%5B3%5D%7B3%5E%7B3%7D%202%5E%7B3%7D%20%7D%20%3D%203%2A2%20%3D%206)
Answer:
3 x 10^-1 km per second.
Step-by-step explanation:
A scientific notation includes c x 10^n. c is a number between 1-9, and n is the nth power of 10.
If we move the decimal in 0.3 to the right by 1 place, we can get "c", which will be 3. Since we have moved the decimal to the right, each place moved right counts as -1 for n.
So, the answer is 3 x 10^-1 km per second.
.45= 45%
100%(total)-45%(boys)=55%(or .55; not boy)
%*Total=Part
.55*20=11
