Answer:
x=0
Step-by-step explanation:
3=3(x-5)-3(x-6)
3=3x-15-3x+18
3+15-18=3x-3x
18-18=0x
0=0x
x=0
To find out we must divide total cups' amount by a serving's amount, so :
There are 48 servings in the cooler.
Answer:
tip = 3.07
final bill = 18.40
Step-by-step explanation:
To find the tip, we take the percent times the bill
tip = 20% * 15.33
.20 *15.33
3.066
Rounding to the nearest cent
3.07
The final bill is the tip plus the bill
final bill = 15.33+3.07
18.40
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.
