There are 233 feet of wood that are required, but we can only buy in lengths of 11 feet. Therefore, we have to take the ceiling of the division 233/11 because if you take less than what you need, you won't have enough, but if you take more than you need, but only the bare minimum of it, you will have enough without wasting money. Therefore, 233/11 = 21, but you have that extra couple feet left, so you need to buy an extra plank to get 22 planks of wood.
No.
Their product is always greater than 0.
So basically the hypotenuse is the part of the triangle that connects the two sides that create the right angle
Let's assume
people were in the original group of winners as x
A group of winning ticket holders share equally 90,000,000 lottery
Before the money is divided, three more winning ticket holders are declared
so, total number of winning tickes =x+3
each persons share is reduced to 5,000,000
so, total money =5,000,000*(x+3)
and this must be equal to total money
now, we can solve for x
and we get
Subtrac both sides by 3
so,
number of people were in the original group of winners is 15 ...........Answer
You should try both points
put x=5/2 and y=3
5-2=3
the first one is on the graph
put x=3/2 and y=20
3-40/3≠3
the second one is not on the graph
