A^2 + b^2 = c^2....where a and b are the legs, c is the hypotenuse
3^2 + b^2 = 7^2
9 + b^2 = 49
b^2 = 49 - 9
b^2 = 40.....take sqrt of both sides, eliminating the ^2
b = square root of 40 <==
Tickets numbered 1 - 30.......greater then 20, less then 30 = (21 - 29) = 9 tickets......9/30
tickets numbered 21 - 48...greater then 20 or less then 30 = (21 - 29) = 9 tickets.....9/28
9/30 * 9/28 = 81/840 = 27/280
Answer:
125 inches cubed
Step-by-step explanation:
First, you find the volume of the full square, and then you divide your answer by 2, since the figure is a triangle.
So,
10 x 10 x 2.5 = 250
250 ÷ 2 = 125 inches cubed
