She can carry 5 books, because 2 + 1 = 3 and 18 - 3 =15, so then multiply 3 times 5 because 3 times 5 is 15. I hope this helped!
To calculate the perimeter, consider each side separately.
Right side: This is easiest since it's a vertical line - it's 7 units long.
Top side: If you look carefully, this side is really the hypotenuse of a triangle that is 1 unit tall and 6 units long. Using the Pythagorean Theorem, you can calculate the length of the hypotenuse to be 1^2 + 6^2 = c^2 --> c = 6.1
Left side: just like the top side, this side is the hypotenuse of a triangle that is 6 units tall and 6 units long. Pythagoras again: 6^2 + 6^2 = c^2 --> c = 8.5
Add these three numbers to get the perimeter: 7 + 6.1 + 8.5 = 21.6
2/3-2i hope this helps you
110 is the answer of this question
There are 100 possibilities for the last two digits [ if we include
00].....therefore....you have 1/100 chance [1 % ] chance of
choosing the correct one.....
