The answer is d. I got that by adding 1/3 + 1/3 + 1/3 + 1/2 + 2/3 = 2 1/6
Answer:
t = 2.5 s
Step-by-step explanation:
Suppose you have a water-balloon launcher. The balloon is 3 ft high when it leaves the launcher. Its equation is :
The above equation is a quadratic equation. The general equation is :
Here, a = 16, b = 38.8 and c = 3
The solution of quadratic equation is given by :
So, at t = 2.5 s the balloon is in air.
Let's say the dog jumps 100 feet every jump, (Yes, I know that it's illogical, but it makes this problem so much easier.) and that it jumps 1 time every second.
100 · 1 = 100, so Dog goes at 100 feet per second.
Cat jumps 5% shorter, so it is 95 feet per jump. However, it jumps 5% more than dog, so it jumps 1.05 times every second. You multiply.
95 · 1.05 = 99.75. So Cat goes at 99.75 feet per second.
100 > 99.75
Dog is going to win the race.
In order to get rid of the fractions, you need to multiply the equation by 12
