1 yd = 3 ft 1 foot = 12 in 1 foot squared = 12 inches x 12 inches 1 foot squared = 144 squared inches 1 yard squared = 3 feet by 3 feet 1 yard squard = 9 squared feet 1 yard squared = 9 squared feet x 144 squared inches 1 yard squared =1296 squared inches 5 yards squared = 1296 squared inches x 5 5 yards squared = 6480 inches squared
196 squared = 38416
The sum of the first 450 consecutive odd numbers is 450 squared or 202,500.
F = ma Force (in Newtons) equals mass (in kilograms) times acceleration (in meters per second squared) In this case, 450 = 30a, so the accelerating is 15 meters per second squared
Say you know the surface area of said cube is 450. cubes have six sides, so you need to find the area of one of them by doing 450/6 = 75. Think about 2d geometry. If you have a rectangle, how do you find it's diagonal? Using the Pythagorean theorem 'a' squared plus 'b' squared equals 'c' squared (keep in mind a + b doesn't equal c). so to get the interior diagonal, you need the diagonal of one of the faces and the length of a side. then re-use pythagorean to get it.
KE = (1/2)mass * velocity squared KE = 1/2(100 kg)(3 m/s)2 = 450 Joules =========
80 percent of 450 = 36080% of 450= 80% * 450= 0.80* 450= 360
40% of 450 = 18040% of 450= 40% * 450= 0.40 * 450= 180
he made the theorem C squared = A squared + B squared and A squared = C squared - B squared or B squared = C squared - A squared
450
80 percent of 450 = 36080% of 450= 80% * 450= 0.80* 450= 360
12.5% of 450= 12.5% * 450= 0.125 * 450= 56.25
3x squared - x squared = 2x squared
15% of 450 = 15% * 450 = 0.15 * 450 = 67.5
