A six row combin harvests 266 pounds of corn per min. How many bushels of corn does it harvest per hour? (Note: 1 Bu = 56 Lbs) R
kiruha [24]

Answer:

The six-row combin harvests 285 bushels of corn per hour.

Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three.

If the relationship between the magnitudes is direct, you can apply the following formula:

a ⇒ b

c ⇒ x

So: x=\frac{a*b}{c}

In this case you can apply it in the following way: if 56 pounds is equal to 1 bushel, 266 pounds to how many bushels is it?

x=\frac{266 pounds*1 bushel}{56 pounds}

x=4.75

This is, a six row combin harvests 4.75 bushels of corn per min.

So, being 1 hour equal to 60 minutes, you can apply the following rule of three: if in 1 minute a six-row harvester harvests , in 60 minutes how many bushels of corn it harvests?

bushels of corn=\frac{60 minutes*4.75 bushels of corn}{1minute}

bushels of corn=  285

<u><em> The six-row combin harvests 285 bushels of corn per hour.</em></u>

Mutually exclusive is an statistical term which means the probability of occurrence of two separate event at the same time is zero. It means two events can not be occurred simultaneously.

For example, if we roll the deck ant the probability of coming 1 and 6 at the same time is zero and both events do not depends upon each others occurrence.

Hence only one drama can run in theater at one time. So they are mutually exclusive events.

I believe the third choice is correct.

This can be proven by the fact that to find the molar mass of a compound, you simply add the molar masses of all the atoms within the compound

Hope this helps
