Answer: It is a composite number since it has more factors than just itself and 1.
Step-by-step explanation:
1x20=20
2x10=20
4x5=20
Hello,
Penny==>a*10 (a is an integer)
Kenny==>b*18 (b is an integer)
a*10=b*18==>a=9*b/5 ==>b=5+n*5
a=9*(5+5*n)/5=9*(1+n)=9+9n
If n=0 then a=9 and b=5 :Number od cards: 9*10=10, 5*18=90
if n=1 then a=19 and b=10: Number of cards: 19*10=190>100 to exclude.
So number of cards=90
An=Asub1(r)n-¹
=5(-2)7-¹
=5(64)
A7=320
Vertex point: (1, -4)
X-intercepts: (-1, 0) , (3, 0)
Y-intercept: (0, -3)
Axis of symmetry: x = 1
This function will create a parabola that opens upwards. I’m not entirely sure what I was supposed to answer. Hopefully this covered it. I’ll attach an image of the parabola in case I missed anything.
Converting the mixed number to a decimal, the correct comparison of the numbers is given as follows:

<h3>What is a mixed number?</h3>
A mixed number is represented by an integer part and a fractional part, as follows:
a b/c.
In which:
- b/c is the fractional part.
In this problem, the numbers are given as follows:

The mixed number is:
100 and 2/8 = 100 + 0.25 = 100.25.
The square root is an increasing function, hence the higher the input, the higher the square root, as 180 > 100 the comparison is:
