The cows of Argentina needs an approximate area of 4200 m² for grazing, and there is a total of 4500 cows.
And we are asked to find the total area of their grazing but in hectares. So, we can write:

Then, for 4500 cows:


We know that, 1 hectares = 10000 m² = 10⁴ m²
Then let the area of the field be x in hectares:


Then, putting them in proportion, We will get:


So, the total area in hectares = <u>1</u><u>8</u><u>9</u><u>0</u><u> </u><u>hectares</u><u>.</u>
And we are done !!

I see so many people ask this. What does this mean?
Answer:
Step-by-step explanation:
Given that Jack divided his fortune of 92,000 into 8 equal portions.He gave 4 portions to his wife , 1 portion to his son and divided the remaining portions equally among 5 charities.
The portion son gets = 
Charity on the whole gets = 3 portions = 
Each charity gets = 
Thus we find son gets 11500 dollars while each charity gets 6900 dollars.
The difference = 
4600 dollars he got more.
The shape would be exactly the same because any number multiplied by 1 equals itself.
As the angle is greater than 0° and less than 90°, then the angle ABC is acute. (Answer: A)
<h3>How to determine the features of an angle set on Cartesian plane</h3>
Herein we find the locations of the three vertices of the figure, of which we must determine the lengths of the two sides of the angle and determine the value of the angle by trigonometry:
BA = 5, BC = 2
θ = tan⁻¹ (BA / BC)
θ = tan⁻¹ (5 / 2)
θ ≈ 68.199°
As the angle is greater than 0° and less than 90°, then the angle ABC is acute. (Answer: A)
