Step-by-step explanation:
Answer:
x = 10
Step-by-step explanation:
OA = OD ( both radii of the circle )
OD = OB + BD = x + 16
OB is at right angles to OB ( line from centre to midpoint of chord is right )
Using Pythagoras' identity in right triangle ABO
OA² = OB² + AB² , that is
(x + 16)² = x² + 24²
x² + 32x + 256 = x² + 576 ( subtract x² from both sides )
32x + 256 = 576 ( subtract 256 from both sides )
32x = 320 ( divide both sides by 32 )
x = 10
Answer:
12
Step-by-step explanation:
13 + 6 + 2x -18 = 4x - 29
19 + 2x -18 = 4x -29
2x + 1 = 4x - 29
30 = 2x
15 = x
CD = 2(15) -18
CD = 30 -18
CD = 12
Answer:
300
Step-by-step explanation:
to find volume u will have to multiply the length x width x breadth which is 5x5x12=300
Answer:
0.007mph
Step-by-step explanation:
Just divide the speed by the time, and you've got it!
