Is it possible to draw a triangle with numbers 5,6,11
Tatiana [17]

Answer:

No

Step-by-step explanation:

Let's use the Pythagorean Theorem. For those of you that don't know, it is a^2 + b^2 = c^2\\.  

11 is the bigger side in this case, so our formula would go like this: 5^2 + 6^2 = 11^2\\.

We now calculate to see if this is true.

25 + 36 \neq 121

Therefore, the answer is wrong.

Komodo dragons are the heaviest lizards on earth. A baby Komodo dragon is 1 3/4 feet long when it hatches. It’s mother is 8 3/4
sukhopar [10]

Answer:

An adult male Komodo dragon is 10\frac12 feet.

Therefore the male is 1\frac34 feet longer than the mother.

Step-by-step explanation:

Given that,

A baby dragon is 1\frac34 feet long.

It's mother is 8\frac34 feet.

An adult male Komodo dragon is 6 times as long as the baby Komodo dragon.

So, an adult male Komodo dragon is =(6×1\frac34 ) feet

                                                          =6\times \frac74 feet

                                                          =\frac61\times \frac74 feet

                                                         = \frac {21}2 feet.

                                                         =10\frac12 feet.

\therefore 10\frac 12- 8\frac34

=\frac{21}{2}-\frac{35}4

=\frac{21\times 2-35\times 1}{4}

=\frac{42-35}{4}

=\frac74

=1\frac34

Therefore the male is 1\frac34 feet longer than the mother.

Isabella save 2 nickels today, if she doubles the number of Nicole, she saves every day, how many days, including today, will it
Elden [556K]

Answer:

  8 days

Step-by-step explanation:

On day 8, Isabella will save 256 nickels, bringing her total to 510.

_____

The number of nickels saved on day n is 2^n. The total is 2^(n+1)-2.

_____

The above can be written down from your knowledge of binary sequences. If you want a more formal development, read on.

__

The number of nickels saved on day n is a geometric sequence with first term 2 and common ratio 2. The n-th term of the sequence is ...

  an = a1·r^(n-1) = 2·2^(n-1) = 2^n

The sum of n terms of the sequence is ...

  S = a1(r^n -1)/(r -1) = 2(2^n -1)/(2-1)

  S = 2^(n+1) -2

__

We want S > 500, so ...

  500 < 2^(n+1) -2

  502 < 2^(n+1)

  251 < 2^n

  log(251) < n·log(2)

  n > log(251)/log(2)

  n > 7.97 . . . . . . . . 8 days or more to save more than 500 nickels
