An animal park has lions, tigers and zebras. 17% of the animals are zebras. What percentage are tigers? Show me your work!
1 answer:
Answer:
53% are tigers
Step-by-step explanation:
If you were referring to the question:
<u><em>An animal park has lions, tigers and zebras. 17% of the animals are lions and 3/10 of the animals are zebras. What percentage are tigers? Show me your work! </em></u>
We can then solve it by considering what is 3/10 in percent form.
When you think of percent, just remember that it is a portion for every 100. So think of a fraction that is proportional to 3/10 that is a fraction of 100:
So 3/10 = 30/100 which in percentage form is 30%.
Now if:
17% = lions
30% = zebras
We can get the percentage by looking for how many out of 100% is left.
100% - (17% + 30%)
100% - 47%
53%

Factoring, you have
h(t) = -16(t^2 -2 -8) = -16(t -4)(t +2)
The ball hits the ground when h(t) = 0, so
0 = -16(t -4)(t +2)
t = 4 or -2
The positive solution is the one of interest.
It will take 4 seconds for the ball to hit the ground.
