Ella’s book collection contains 12 books, including 3 mysteries. If Ella randomly selects a book to read, what is the probability that it will be a mystery

25%

Step-by-step explanation:

Mystery books=3

Total books= 12

Therefore, other books are 12-3=9

Probability of a mystery book will be 3/12=1/4=0.25=25%

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
