<span>ABC IS AN ANGLE FORMED BY A TANGENT AND CHORD WITH AN INTERCEPTED MINOR ARC FROM A TO B. WHEN TWO CHORDS INTERSECT INSIDE A CIRCLE, FOUR ANGLES ARE FORMED. AT THE POINT OF INTERSECTION, TWO SETS OF CONGRUENT VERTICAL ANGLES ARE FORMED IN THE CORNERS OF THE X THAT APPEARS.</span>
Answer:Four years ago, Alex was twice as old as Jake. Four years from now, Jake will be 3/4 of Alex's age. How old is Alex? - Answer: 12.
Step-by-step explanation:
1 mile = 1.6km.

42
Step-by-step explanation:
3/4 is division which equals .75
0.75 x 56 = 42
Answer:
about 0.20
Step-by-step explanation:
The speed, acceleration, and distance satisfy the equation ...
v² = 2ad
So the acceleration is ...
a = v²/(2d) = (6 m/s)²/(2×9 m) = 2 m/s²
If we take the acceleration due to gravity to be 9.8 m/s², the coefficient of kinetic friction is the ratio of these:
k = (2 m/s²)/(9.8 m/s²) ≈ 0.20
