Answer:

The cow's heart beats at a rate of    65  beats per minute.

Step-by-step explanation:

Pig: 225 ÷ 3 = 75, not right.

Horse: 180 ÷ 4 = 45, not right.

<u>Cow:  520 ÷ 8 = 65, correct!</u>

Dog: 540 ÷ 6 = 90, not correct.

So as we can see the cow is the right answer.

HELP......................................
djyliett [7]

Answer:

The equation's result: 32,000 (Rounded)

Goal: Find the closest or equivalent result in another expression

Step-by-step explanation:

<h3>A)</h3>

(1.5^{15})/(0.7^{12})\\(1.5^{15})/(0.7^{12}) = (437.894)/(0.7^{12})\\437.894/(0.014)\\31636.79

How we got to 31,636 was by dividing from left to right.

Remember: When dividing decimals, it's like multiplying whole numbers in a way. The number(the quotient, also) ends up bigger instead of being smaller like when dividing whole numbers. If you multiply decimals, they(the product) end up smaller.

Therefore, A is the correct answer.
