3 apples are to be divided up amongst 4 friends. 3/4 = 0.75 apples per person.
Answer:
5/8
Step-by-step explanation:
i took the test hope this helps
We have that
y=x²----> equation 1<span>
y=x+2-----> equation 2
multiply equation 1 by -1
-y=-x</span>²
add equation 1 and equation 2
-y=-x²
y=x+2
------------
0=-x²+x+2-------------> -x²+x+2=0-----> x²-x-2=0
Group terms that contain the same variable, and move the
constant to the opposite side of the equation
(x²-x)=2
<span>Complete
the square. Remember to balance the equation by adding the same constants
to each side
</span>(x²-x+0.5²)=2+0.5²
Rewrite as perfect squares
(x-0.5)²=2+0.5²
(x-0.5)²=2.25-----> (x-0.5)=(+/-)√2.25-----> (x-0.5)=(+/-)1.5
x1=1.5+0.5-----> x1=2
x2=-1.5+0.5---- > x2=-1
for x=2
y=x²----> y=2²----> y=4
the point is (2,4)
for x=-1
y=x²----> y=(-1)²---> y=1
the point is (-1,1)
the answer isthe solution of the system are the points(2,4) and (-1,1)

24 different ways can they line up to receive their championship rings.
What is a permutation mean in math?
- When the order of the arrangements matters, a mathematical technique called a permutation can be used to calculate the number of alternative arrangements in a collection.
- Common mathematics problems involve choosing only several items from a group of items in a specified sequence.
What are permutations used for?
- When an arrangement requires an order or a sequence, permutations are used.
- Combinations are employed when determining merely the number of potential groups is required and neither the order nor the sequence of arrangements is necessary.
Given,
No. of captains of the football team = 4
So,
4 ways we can line up their championship rings = (4,4)
4 ×3 ×2 ×1 = 24
Therefore, 24 different ways can they line up to receive their championship rings.
