Joshua uses a rule to write the following sequence of numbers 1/6,1/2,5/6,----------,11/2 What rule did Joshua use? What is the

Pani-rosa [81]

Answer: The missing number in the sequence is $\frac{7}{6}$

Step-by-step explanation:

Since we have given that

$\frac{1}{6},\frac{1}{2},\frac{5}{6},----------,\frac{11}{2}$

First term = a= $\frac{1}{6}$

Common difference = d is given by

$d=a_2-a_1\\\\\frac{1}{2}-\frac{1}{6}\\\\=\frac{6-2}{12}\\\\=\frac{4}{12}=\frac{1}{3}\\\\Similarly,\\d=a_3-a_2\\\\=\frac{5}{6}-\frac{1}{2}\\\\=\frac{10-6}{12}\\\\=\frac{4}{12}\\\\=\frac{1}{3}$

Therefore, it forms an arithmetic sequence.

Since, $a_4$ is missing,

So,

$a_4=a+3d\\\\a_4=\frac{1}{6}+3\times \frac{1}{3}\\\\a_4=\frac{1}{6}+1\\\\a_4=\frac{1+6}{6}\\\\a_4=\frac{7}{6}$

Hence, the missing number in the sequence is $\frac{7}{6}$

A molecule of butane contains 10 atoms of hydrogen to every 4 atoms of hydrogen to every 4 atoms of carbon. Could a compound con

Naily [24]

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!!!
