Answer:
No
Step-by-step explanation:
Let's use the Pythagorean Theorem. For those of you that don't know, it is 
.
11 is the bigger side in this case, so our formula would go like this: 
.
We now calculate to see if this is true.
25 + 36 
121
Therefore, the answer is wrong.
Answer:
Yes, the distance between the points would be 8
Step-by-step explanation:
Since the y is the same, you can just find the distance between 12 and 4
12-4=8
Answer:
An adult male Komodo dragon is 
feet.
Therefore the male is 
feet longer than the mother.
Step-by-step explanation:
Given that,
A baby dragon is feet long.
It's mother is 
feet.
An adult male Komodo dragon is 6 times as long as the baby Komodo dragon.
So, an adult male Komodo dragon is =(6× ) feet
feet
feet
= 
feet.
feet.
Therefore the male is feet longer than the mother.
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
8 * 684 = 5472
it is in between 5471 and 5473
