Answer:

C. six

Step-by-step explanation:

A hexagonal prism has 18 edges and a hexagonal pyramid has 12 edges, therefore the difference between the number of edges of the two solids is six (6) because 18-12 is 6.

The word "difference" infers that we need to subtract numbers in order to find how many are left.

A six feet-tall person is standing next to a flag pole.The person is casting a shadow 1 1/2 feet in length,while the flagpoleis
Vlad1618 [11]

Answer:

20 feet

Step-by-step explanation:

Consider the given pictorial representation below,

The Height of the Pole =|AB|

The Height of the Person =|DE|

Shadow cast by the Pole =|AC|

Shadow cast by the Person =|EC|

Triangles ABC and DEC are similar triangles therefore,

\frac{|DE|}{|AB|} =\frac{|EC|}{|AC|}

\frac{6}{x} =\frac{1.5}{5}

Cross multiplying

x X 1.5 = 6 X 5

x=30/1.5 =20 feet

Height of the flag pole = 20 feet

In a fibonacci sequence, the first number is 1 and the tenth number is 111. find the second number.
Schach [20]

Let x be the second number in the Fibonacci sequence.

Then we have the sequence is as follows:

1st: 1
2nd: x
3rd: 1 + x
4th: 1 + 2x
5th: 2 + 3x
6th: 3 + 5x

7th: 5 + 8x

8th: 8 + 13x

9th: 13 + 21x

10th: 21 + 34x

so 111 = 21 + 34x, so 34x = 90, so x = 90/34 = 45/17.

Thus the second term would be 45/17. (if I haven’t made any errors in arithmetic).
