Answer:

18581.16

Step-by-step explanation:

The area of each of the shale can be calculated as

distance between each point = x

The area of the regular Dodecahedron

A = \sqrt[3]{25+10\sqrt{5} }   a^{2}

where a = number of edges = 30

hence the area of the regular dodecaheron = 18581.16

Solve for x.<br> 9 &lt;17 - 4.0<br> Enter your answer, as an inequality, in the box.
Rashid [163]

9 <= 17 -4x

Subtract t 17 from both sides:

-8 <= -4x

Divide both sides by-4,

2 <= x

Rewrite the inequality with the x on the left side.

Answer: x <=2

1 . The lengths of the legs of a right triangle are 25 cm and 60 cm. What is the length of the hypotenuse?
Svetlanka [38]
a^{2}+ b^{2} = c^{2} that is, hypotenuse.
Therefore, let the length of the hypotenuse be 'x.' 
25^{2}+ 60^{2}= x^{2}
625+3600=x^{2}
4225=x^{2}
Therefore,
\sqrt{4225}=x
65=x
The length of the hypotenuse is B.65 centimetres.

How do you do these 2 questions?
zavuch27 [327]

Answer:

0 ≤ an ≤ bn

The series ∑₁°° bn converges

The series ∑₁°° an converges by comparison to ∑₁°° bn.

0 ≤ an ≤ bn

The series ∑₁°° bn diverges

The comparison test is inconclusive for our choice of bn.

Step-by-step explanation:

an = 1 / (n² + n + 3) and bn = 1 / n²

The numerators are the same, and the denominator of an is greater than the denominator of bn.  So 0 ≤ an ≤ bn.

bn is a p series with p > 1, so it converges.

Since the larger function converges, the smaller function also converges.

an = (3n − 1) / (6n² + 2n + 1) and bn = 1 / (2n)

If we rewrite bn as bn = (3n − 1) / (6n² − 2n), we can tell that when the numerators are equal, the denominator of an is greater than the denominator of bn.  So 0 ≤ an ≤ bn.

bn is a p series with p = 1, so it diverges.

The larger function diverges.  We cannot conclude whether the smaller function converges or diverges.

Samia normally works 8 hours a day and earns $X per hour. For each hour she works
Inga [223]

9514 1404 393

Answer:

  $(4/3)X

Step-by-step explanation:

Working 12 hours, Samia gets paid for the first 8 hours ...

  8 · ($X) = $8X

For the remaining 4 hours, she is paid ...

  4 · ($2X) = $8X

Then for 12 hours, she is paid a total of ...

  $8X +$8X = $16X

Her average hourly pay is then ...

  total pay / total hours = $16X/12 = $(4/3)X . . . average hourly pay
