Okay, let's define what a circumference is.
Circumference - The entire outside of a circle, think of it as the "perimeter" of the circle, like how there is a perimeter for a triangle or square.
The equation for finding the circumference is as follows:
[tex]2\pi r[/tex]
r - the radius, or half-way line is a circle.
So, you see the number thats on a half way line in the circle? That is the radius. All you have to do is plug in that number into the equation (for r), and you get the answer.
#3
r = 15
[tex]2\pi (15) = 30\pi \\[/tex]
Now use a calculator and type in 30, then times it by pi (which is this symbol: [tex]\pi[/tex])
Circumference = 94.248
#4
r = 10
[tex]2\pi (10) = 20\pi \\[/tex]
Circumference = 62.832

Naomi is buying bagels for a family gathering. Each bagel costs $1.25. Answer the questions below regarding the relationship between the total cost and the number of bagels purchased.
Answers
Answer:
total cost = 1.50x
Step-by-step explanation:
Given cost of 1 bagel = $1.25
Let the number of bagels purchased by x
cost of x bagels = cost of 1 bagel *x
cost of x bagels = 1.50*x
Thus,
relationship between bagels and total cost is as shown below
total cost = 1.50x
where x is the number of bagels purchased.
Answer:
The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.
A function relating these variables is N(x) = 1.25x.
So N(4) =5, meaning 4 bagels will cost 5 dollars.

Levi has a job offer in which he will receive $800 per month plus a commission of 2% of the total price of the cars that he sells. At his current job, he receives $1200 per month plus a commission of 1.5% of his total sales. How much must he sell per month to make the new job a better deal than his current job? Define variables, write a system of equations, and solve.
Answers
Answer:
Levi must sell more than 80000 cars per month for the new job to be better than the current job.
Step-by-step explanation:
New Job;
He receives $800 per month plus a commission of 2% or 0.02 of the total price of the cars.
Now, let the total amount he receives in a month be "y" and let the amount of cars sold be x.
Thus;
y = 800 + 0.02x - - - -(eq1)
Current Job:
He receives $1200 per month plus a commission of 1.5% or 0.015 of his total sales.
Thus;
y = 1200 + 0.015x - - - (eq2)
Substituting 800 + 0.02x for y into eq(2) gives;
800 + 0.02x = 1200 + 0.015x
0.02x - 0.015x = 1200 - 800
0.005x = 400
x = 400/0.005
x = 80000
This means Levi must sell more than 80000 cars per month for the new job to be better than the current job.

This shape only has 1 line of symmetry, because there is only one way we can split it in half and still have it look exactly the same.

Ecuación 2:
10x + 20y = 8000
ayudaaa
Answers
Answer:
y = 300
x = 200
Step-by-step explanation:
Esta pregunta parece incompleta, parece que acá tenemos un sistema de ecuaciones:
x + y = 500
10*x + 20*y = 8000
Estas ecuaciones tienen que resolverse en conjunto, y de acá sacaremos un par de puntos (x, y) que son solución para ambas ecuaciones.
El primer paso para resolver esto es aislar una variable en una de las ecuaciones, en este caso podemos aislar x en la primera ecuación y así obtener:
x = 500 - y.
Ahora podemos reemplazar eso en la segunda ecuación y obtener:
10*(500 - y) + 20*y = 8000.
Ahora resolvemos esto para y.
5000 - 10*y + 20*y = 8000
10*y = 8000 - 5000 = 3000
y = 3000/10 = 300.
Y sabíamos que:
x = 500 - y = 500 - 300 = 200
Entonces la solución es:
y = 300
x = 200
