I believe it’s A — atoms in solids are closest together, atoms in liquids are close, but not as compact as in solids, and atoms in gasses aren’t close are all, and they’re constantly moving.
First we need to have same units before comparing them. That is, either both of them are in cm or both of them are in mm. So if we need to convert 12.5 cm to mm, we know that 1 cm =10 mm. So we have to find out how many mm are in 12.5 cm. And let 12.5 cm =x mm. So to find the value of x , we set a proportion and solve for x. That is
The units cancel out and we do cross multiplication. That is
x=125
So 12.5 cm =125 mm. Therefore the correct proportion is C.
Answer:
Step-by-step explanation:
w / h = u / HG
w = 8
h = 48
u = 5
lets use h / w = HG / u this is the same relationship but looks easier to me
48/8 = HG / 5
6 = HG / 5
6 * 5 = HG
30 = HG
not too tuff... when you set the relationship so it's easiest :)
and yes.. we cold have swapped the fractions and done it the other way and gotten the same answer.. but maybe with a bit more algebra.. and... avoid extra algebra ... that's where the mistakes can be made :P
Answer:
A. (7n-1) (8n-1)
Step-by-step explanation:
56n^2 -8n-7n+1
56n^2 -8n -7n+1
Factor out 8n from the first group and -1 from the second group
8n (7n-1) -1(7n-1)
Factor out the (7n-1)
(7n-1) (8n-1)
