How many sq ft you would need to built attached car garage?
Basic 2 car garage is 20 x 20. A garage with more utility is usually 24 x 20 up to 26 x 24 for twin door garages. These are pretty common sizes but aren't limited to these by any means. So, 400 to 624 square feet. Or at least 20 feet wide and 20 feet deep.
How much does 13 go into 350?
26 with 12 remaining 350 - 12 = 338 = 13 x 26
What percentage is 15 of 26?
26 * x = 15 x = 15/26 x = .5769 or 57.69%
What is the square footage of a 4 x 8 sheet of drywall?
32 sq feet
What is the probability of getting a license plate that has a repeated letter or digit if you live in a state that has one numeral follwed by seven letters followed by one numeral?
This is easiest to answer by working out the probability of not getting such a license plate and subtracting that from 1. There are 10 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 10 different possible license plates (since there are 10 digits: 0-9 and 26 letters: A-Z). To not have any repeated digits or letters, there are: 10 x 26 x 25 x 24 x 23 x 22 x 21 x 20 x 9 possible license plates (since the two digits must be different and the seven letters must all be different). Meaning the probability of getting one of these is: (10 x 26 x 25 x 24 x 23 x 22 x 21 x 20 x 9)/(10 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 10) = (25 x 3 x 23 x 11 x 21 x 9)/(26 x 13 x 13 x 13 x 13 x 13) = 3586275/9653618 ⇒ probability of getting at least one repeating digit or number is: 1 - 3586275/9653618 = 6067343/9653618≈ 0.629
