Answer:
Step-by-step explanation:
126 mi/h = (126 mi)/(1 h)·(5280 ft)/(1 mi)·(1 h)/(3600 s) = (126·5280/3600) ft/s
126 mi/h = 184.8 ft/s = 924/5 ft/s

In 2 seconds, the parachutist falls ...
(184.8 ft/s)·(2 s) = 369.6 ft

Answer:
C. 5, 12 and 13
D. 6, 8 and 10
Step-by-step explanation:
To see if three side lengths would give you a right triangle, you have to use the Pythagoras Theorem which is a² + b² = c², where c is the hypotenuse (longest side) and a and b are adjacent to the right angle.
A. 3² + 7² ≠ 10²
9 + 49 ≠ 100
58 ≠ 100
B. 4² + 9² ≠ 10²
16 + 81 ≠ 100
97 ≠ 100
C. 5² + 12² = 13²
25 + 144 = 169
169 = 169
D. 6² + 8² = 10²
36 + 64 = 100
100 = 100
0.377 + 5.51 = 5.887
Sorry I can only solve the first one. Could you give me a hint on how to do the second one ?
