Sergio [31]
Hey there!

Here is your answer:

<u><em>The proper answer to this question is "44 times".</em></u>

Reason:

You have to solve it this way:

<u><em>12 heartbeats=16 seconds</em></u>

<u><em>16+16=32</em></u>
<u><em>36+16=48</em></u>
<u><em>48+16=64</em></u>
<u><em>16-12=4</em></u>
<u><em>12+12=36+8=44</em></u>

<em>Therefore lions heart beats 44 times every 60 seconds.</em>

If you need anymore help feel free to ask me!

Hope this helps!

Explain how you would convert a measurement given in ounces into pints
Greeley [361]
8 ounces = 1cup
2 cups = 1 pint
So, 16 ounces = 2 cups = 1pint
16 ounces = 1 pint

If you have 8 ounces, you would have half a pint.
If you have 20 ounces:
20 ounces/16 ounces= 5/4
So, you'd have 1 1/4 or 1.25 pints
