In order to determine the number of pens present in the container, we need to set up equations from the given in the problem statement. We do as follows:
let x the number of pencils
y the number of pens
From the statement, 9 more pencils then pens in a container,
x = y + 9
From the statement, there are 25 writing utensils in the container in all,
x + y = 25
We use substitution method to calculate for x and y,
y + 9 + y = 25
2y = 16
y = 8
x = 17
Therefore, there are 8 pens in the container and 17 pencils.
To find conjecture about regular polygon, use the formula

Where, n = number of sides of the regular polygone
1) Triangle
n =3
So, Conjecture of the triangle =

= 120
2) Square
n =4
So, Conjecture of the square =

= 90
3) Pentagone
n = 5
So, Conjecture of the pentagon =

= 72
4) Hexagone
n = 6
So, Conjecture of the pentagon =

= 60.
Answer:
Mixed fraction = whole × denominator + numerator.
this formula converts mixed to improper fraction.
So, 1 × 3 + 1 = 4 is numerator.
Denominator is 3 which is same.
So, answer is
A.

Answer:
Worked 40 hrs in week
Pay $300 for week
Step-by-step explanation:
Hours: 7-11a.m = 4
12-4p.m = 4 So, 4+4=8 hrs per day
So, 8 hrs per day × 5 days a week (8×5)=40
Worked 40 hrs in week
Pay: $7.50/hr So, $7.50×40 hrs (7.50×40)=300
So, $300 pay for week
One may note the country's name is not finline or Finley, is
Finland.
so, in short, if we take 137 to be the 100%, how much is 18.036 in percentage off of it?
