I am presuming that the question is who won or by how much did the winner win.
distance equals rate times time, or d = r*t
For the Hare d = 1600 and r = 10
1600 = 10 t
Divide both sides by 10
t = 160
The hare finished in 160 seconds
For the tortoise d = 1600 - 780 = 820 (due to the head start) and r = 5.3
820= 5.3 t
Divide both sides by 5.3
t = 154.72 (rounded to the hundredths place)
The tortoise won by 5. 28 seconds (160-154.72)
A. since y will decrease as x increases
Answer:
Step-by-step explanation:

Cross-multiplying will give us the following:

Dividing both sides by
will give us our answer:

Diagonals bisect each other



Option B
Answer:
Step-by-step explanation:
7.4×10^(-8) - 6.7×10^(-9) = 6.73×10^-8 is 9.05405% smaller than 7.4×10^(-8) = 7.4×10^-8
