It is a right Right Triangle because, they have two equal sides.
So I’m guessing 40 is x so if 40 is the hours u put 290=40(3)+50 so then it would be 290=120+50 then it would simplify even more to 170 then 290-170=120 and 120 is ur answer I hope I’m right
4^2 +6^2=x^2
16+36=x^2
52=x^2
Square root of 52= x
X=7.2
All the horses will have eaten 508.2 kg alfalfa after 21 days
Further explanation
<u>Given</u>
Each horse eats 12.1 kg/day
Farmer Brown has 2 horses
In a day Farmer Brown needs:
In 21 days Farmer Brown will need:
to solve this equation we can use partial product or standard algorithm
<u>Partial product</u>
24.2 x 21
= (20+4.2)(20+1)
= (20x20) + (20x4.2) + (20x1) + (4.2x1)
= 400 + 84 + 20 + 4.2
