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.
Answer:
4/3 pi≈3
Step-by-step explanation:
40/360 = 1/9
S= pi*r²* n/360
S= 3*4*1 /9 = 4/3
Answer:
Step-by-step explanation:
w + g = 52
w = 4g - 3
(4g - 3) + g = 52
5g - 3 = 52
5g = 52 + 3
5g = 55
g = 55/5
g = 11....there are 11 green marbles
w + g = 52
w + 11 = 52
w = 52 - 11
w = 41 <=== there are 41 white marbles
