In our base-10 number system, moving a digit one place to the left multiplies its value by 10. Moving it one place to the right multiplies its value by 1/10.
You know already that 1,000 has 10 times the value of 100, and 1/10 the value of 10,000.
Answer:13.86km
Step-by-step explanation: see attachment
If you flip a coin one time, the probability to get a Head is
p = 1/2
The probability of not getting a head in a single toss is :
q = 1 - 1/2 = 1/2
Thus there is only one unique situation to get the same number of heads and tails : in 10 toss you need to get exactly five heads, it will means that the rest is the tails.
Now using Binomial theorem of probability, the probability of getting exactly x = 5 heads in a total of n = 10 tosses is :
P(X = 5) =
≈ 0.246
So the probability of that is 24,6 %
Good Luck

Hello!</h2>
The answer is: The Anya's drawing is 6 inches long.
Have a nice day!
<h2>Why?</h2>
To solve this problem, we need to consider the drawing's length with respect to the actual bug's size, so, the scale factor is:

So, how long is Anya's drawing of the bug?
We can find it, using the following equation:

Hence, the Anya's drawing is 6 inches long.
Have a nice day!
Answer:
8+4√3/2+√3
Step-by-step explanation:
a =2+√3
(a +1/a)
(2+√3+1/2+√3)
(2+√3)^2+1/2+√3
4+4√3+3+1/2+√3
8+4√3/2+√3
