You need to use the Pythagorean theory. a² + b² = c². So you would end up with 10²+10²=c². So, 10²=100, therefore you would end up with 200=c². In order to find the length of the hypotenuse, you need to find C. To do this, you need to undo the square and find the square root of 200 and C. So, you would get √200=√c² which would equal 14.1 inches. Then, if needed to check the answer, plug the 10,10,and 14.1 back into the a²+b²=c² and it should make the statement true.
Answer: 17 people
Step-by-step explanation:
You divide 8 3/4 and 1/2 and you get 17 1/2
And since the question asks how many people can he serve you use the whole number because its not fair if you give a full serving to a person and half a serving to another.
It would be web plato because thats how it is, i think.
I dont know if you know this, but there are 3 different 3's. So how can we figure out the question if we don't know which one is underlined?
Answer:
x=3, y=0.8
Step-by-step explanation:
8x+5y=28
4x+5y=16
Subtract the second simultaneous equation from the first.
You are left with: 4x=12
12/4=3
x=3
Substitute this back into one of the equations.
8(3)+5y=28
8*3=24
28-24=4
4=5y
4/5=0.8
y=0.8
