Answer: 10.9
Step-by-step explanation:
You would use Pythagorean theorem:
5x5+12x12=c
5x5=25
12x12=144
Now, 25+144=169
Now find the square root of 169 which is 13 which isn't an answer choice, which means your prolly after a leg.
I assume 12 is the hypotenuse
A(squared)+5x5=12x12
A+25=144
144-25=119
Square root of 119=10.9
So I'm going to go with answer 10 in or 11 if you round.
Hello, there!
There are 365 days in a year.
We already know that one person has a birthday on blank day. We will call this person a. That means that there is a 100% chance that they have that birthday.
Because there are 365 days in a year, the odds of person b having a birthday on a certain day is 1/365
Odds of person A having that birthday: 365/365
Odds of person B having that birthday: 1/365
To find the odds of them having the same birthday, we must multiply these odds.
365/365 * 1/365 = 1/365
1/365 = 0.27%
This means that there is a 0.27% chance that both people share the same birthday.
I hope I helped!

Answer:

Step-by-step explanation:
The problem needs application of law of indices

This means common power for terms can be applied to each term individually.

Separate power for the terms having same base can be added together.
_______________________________________________________
we will be using these law of indices in the problem

applied the first rule of indices as mentioned above

applied the second rule of indices as mentioned above
Thus, simplified form of (3xy)^2x^4y is
