R = laps she runs
s = laps she swims
each r (laps she runs) takes 5 min.
each s (laps she swims) takes 3 min.
She wants to run for 30 min.
So your inequality should = 30
Answer:
Okapi 290 kg
Llama 160 kg
Step-by-step explanation:
Let weight of each llama be 
Let weight of each okapi be 
<em>Given, combined weight of 1 okapi and 1 llama is 450, we can write:</em>
<em>
</em>
<em>Also, average weight of 3 llama is 190 more than the average weight of 1 okapi, thus we can write:</em>
<em>
</em>
Now, substituting 2nd equation into 1st equation, we can solve for weight of 1 llama:

Each llama weights 160 kg, now using this and plugging into 2nd equation, we get weight of 1 okapi to be:

Each okapi weigh 290 kg
384/6 (amount of faces) = 64
64/2 (area= l*w) = 32
32*3 (volume=l*w*h) = 96
I'm pretty sure this is correct, maybe just double check and see if this makes any sense according to what you're learning? I'm almost 100% sure. Hope this helps!

Formula
-------------------------------------------------------------------------
Surface area = 2πr² + 2πrh
-------------------------------------------------------------------------
Find Surface Area
-------------------------------------------------------------------------
Total surface area = 2 x π x (13.5)² + 2 x π x (13.5) x (90)
Total surface area = 364.5π + 2430π
Total surface area = 2794.5π
Total surface area = 8774.73 unit² (Take π as 3.14)
-------------------------------------------------------------------------
Answer: 8774.73 unit²
