Answer:
G
Step-by-step explanation:
Since there are 50 students being asked, to find a percentage, put the output (the number of students that chose each genre) and the input (the number of students asked all together) in ratio form as a fraction. You will get the fractions 10/50, 16/50, 20/50, and 4/50. Multiply each denominator by two to get the percentage. You will get 20/100, 32,/100, 40/100, and 8/100. If you look at the four answers provided, you can cross out J immediately because it shows that "Other" was the greatest percentage, when it is in fact the smallest. H can be crossed out as well, since the percentage for "Mystery" is over 20% when it should be exactly at 20%. F can be crossed out as well because it shows that "Other" takes up 10%, when it is actually a bit less, 8%. G is the best choice because the percentage that "Other" takes up is a bit less than 10%, so it's safe to say that it shows 8%.
So, here you have to look at the periodic table and see what the molar mass of each molecule composing the water compound
![H_2 O](https://tex.z-dn.net/?f=H_2%20O%20)
its two hydrogen atom plus an oxygen molecule, making it about 18g per mol.
That said, looking at the mass, we have to ask ourselves, if a mol of water contains 18g of mass, how many moles do we have in 0.5g of water?
We just do a cross multiplication:
Answer:
![\sqrt{145}](https://tex.z-dn.net/?f=%5Csqrt%7B145%7D)
Step-by-step explanation:
The distance formula states that the distance between two points
and
is
.
The two points we have are
and
. Plugging these numbers into the distance formula, we have
.
Simplifying with order of operations, first using the distributive property, gives
.
Squaring and adding gives
![\sqrt{(4+4)^2+(6+3)^2}=\sqrt{8^2+9^2}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\sqrt{64+81}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\boxed{\sqrt{145}},](https://tex.z-dn.net/?f=%5Csqrt%7B%284%2B4%29%5E2%2B%286%2B3%29%5E2%7D%3D%5Csqrt%7B8%5E2%2B9%5E2%7D%5C%5C~~~~~~~~~~~~~~~~~~~~~~~~~~~~%3D%5Csqrt%7B64%2B81%7D%5C%5C~~~~~~~~~~~~~~~~~~~~~~~~~~~~%3D%5Cboxed%7B%5Csqrt%7B145%7D%7D%2C)
which is the answer in simplest form. This also rounds to about 12.04.
I think the answer would be 2.05 because 6.15/3 is 2.05
Answer:
48 :)
Step-by-step explanation:
120 divided by 10 = 12
12 x 4 = 48
