Answer:
14 pages remain blank
Step-by-step explanation:
subtract 50-8 and u get 42. 42 is how many pages r left so u figure out 2/3 of 42 which is 28 so 28 pages are about her friends. To figure out how many pages are left blank u would subtract 42-28. 42-28=14 so 14 pages r left blank.
Answer:
Top: Ne: Day, Summer. Nw: Night, Winter.
Position 2 Top: Ne: Night, Winter. Nw: Day, Summer
Bottom P1: Se: Day, Summer. Sw:Night, Winter.
Bottom P2: Se: Night, Winter. Sw: Day, summer
Step-by-step explanation:
In order to find scientific notation you have to move the decimal (which is located at the end of the number in the case) where it becomes a number less than 10 but greater than 1.
(190,000.) = (1.9)
How ever many times you moved the decimal (in this case 5) will now become the exponent (whether the exponent is positive or negative will tell you whether to move left or right)
(1.90,000.)
(5)
As an end result 190,000 in scientific notation will then equal 1.9x10^5
Answer:
Yes this compound could be shown to be butane, specifically, it can be shown to be 9 molecules of butane. Check Explanation for more.
Step-by-step explanation:
Butane contains 10 hydrogen atoms for every 4 carbon atoms. It's molecular formula is C₄H₁₀
The hydrocarbon compound presented has 36 carbon atoms and 90 hyfrogen atoms
If the ratio of each of these atoms present is also in the ratio 4:10 like C:H, then, it can be inferred that the compound is indeed Butane
C | H
36 | 90
dividing through by 9, we have
C | H
4 | 10
which is the exact ratio of Carbon to Hydrogen in butane.
Hence, the unknown compound is most likely 9 molecules of butane
9C₄H₁₀ = 36 carbon atoms and 90 hydrogen atoms.
Hope this Helps!!!
