which figures are polygons
Polygon: a figure formed by coplanar segments
with one distinct interior region
Figure A, Figure B, and Figure D would be considered polygons.
Notice that those figures I mentioned above are
composed of line segments, and nothing else.
In addition, these figures don't have two separate
interior regions and figures that do aren't polygons.
Figure C would not be a polygon because
it's formed by a curve rather than line segments.

A man has a fish tank with the following dimensions:
24cm
29 cm
41 cm
He needs to know approximate volume of the tank.
What is its approximate volume?
Answer:
28,536 centimeters cubed
Step-by-step explanation:
1. Multiply 24x29x41.
2. 24x29 = 696, 696x41 = 28536
3. Since there are three numbers with cm, it would be described as cubed.
Currently, I am 9 times as old as my son. Next year, I will be 7 times as old as my son. How old is my son now?
Answer:
3
Step-by-step explanation:
3x9=27
4x7=28
Your son is 3 years old now
Step-by-step explanation:
If you do 9 times 3, you would get 27, and when you do 4 times 7, you would get 28. So, it makes sense since you get 1 year older and you are 9 times as old and then you will be 7 times as old. So, right now, your son is 3 years old.
Solve 20x= 10 for x
x= 1/2
x= 1.5
x= 2
x= 10
Start by isolating the x term which is 20x by dividing both sides by 20.
That leaves you with x = 10/20 which can be reduced to x = 1/2.

Arianna and her friend Alexa are going to a carnival that has games and rides. Arianna played 6 games and went on 2 rides and spent a total of $21.50. Alexa played 10 games and went on 7 rides and spent a total of $53.25. Write a system of equations that could be used to determine the cost of each game and the cost of each ride. Define the variables that you use to write the system.
Answer:
6x + 2y = 21.50 equation (i)
10x + 7y = 53.25 equation (ii)
Where x represent game and y represent ride.
Cost of 1 game = $2
Cost of 1 ride = $4.75
Step-by-step explanation:
To solve this question, we have to write two set of equations, each giving details of account of the two parties involved.
Let x represent games
Let y represent rides
So, with Arianna,
6x + 2y = 21.50.......equation (i)
With Alexa,
10x + 7y = 53.25 ........equation(ii)
We can solve this equations and go ahead to find the cost of ride and game using simultaneous equation
From equation (i)
6x + 2y = 21.50
Make x the subject of formula,
6x = 21.50 - 2y
x = (21.50 - 2y) / 6 ......equation (iii)
Put equation (iii) into equation (ii)
10x + 7y = 53.25
10 [(21.50 - 2y) / 6] + 7y = 53.25
(215 - 20y) / 6 + 7y = 53.25
(215 - 20y + 42y) / 6 = 53.25
215 + 22y = 53.25 × 6
215 + 22y = 319.5
22y = 319.5 - 215
22y = 104.5
y = 4.75
Put y = 4.75 in either equation (i) or (ii) to find x.
From equation (i)
6x + 2y = 21.50
6x + 2(4.75) = 21.50
6x + 9.5 = 21.50
6x = 21.50 - 9.5
6x = 12
X = 12 / 6
X = 2
Therefore the cost of 1 game is $2 and 1 ride is $4.75
The system of equations are, [tex]6x+2y=21.5[/tex] and [tex]10x+7y=53.25[/tex]
where cost of each game is x dollar and cost of each ride is y dollar.
Let us consider that cost of each game is x dollar and cost of each ride is y dollar.
Since, Arianna played 6 games and went on 2 rides and spent a total of $21.50.
[tex]6x+2y=21.5[/tex]
and Alexa played 10 games and went on 7 rides and spent a total of $53.25.
[tex]10x+7y=53.25[/tex]
Hence, the system of equations are, [tex]6x+2y=21.5[/tex] and [tex]10x+7y=53.25[/tex]

What are the slope and the y-intercept of the linear function that is represented by the equation y = negative 10 x + 1? The slope is –10, and the y-intercept is –1. The slope is –10, and the y-intercept is 1. The slope is –1, and the y-intercept is –10. The slope is 1, and the y-intercept is –10.
Answer:
2. the slope is -10 and y-intercept is 1
Step-by-step explanation:
hope this helps!
Answer:
B. The slope is –10, and the y-intercept is 1.
Step-by-step explanation:
Our equation is y = -10x + 1. Notice that this is of the form y = mx + b, which is called the slope-intercept form because it literally gives us the slope and y-intercept in the equation:
- m: this is the slope value
- b: this is the y-intercept
Here, m = -10, which means the slope is -10. Also, b = 1, so the y-intercept is 1.
Thus, the answer is B.
Rectangle floor measures 10 1/8 by 13 3/4 feet. If Mary buys 150 ft.² of carpet, will she have enough carpet to cover the floor?
Show Work Please Due Today
Answer:
YES
Step-by-step explanation:
Calculate the actual floor area: A = (10 1/8 ft)(13 3/4 ft), or, as decimal fractions,
A = (10.125 ft)(13.75 ft) = 139.22 ft^2
Mary's purchase of 150 ft^2 of carpet is more than enough to cover 139.22 ft^2. YES, she will have enough carpet.

Answer:
a. 0.8x+1.25y
b. $5.70
Step-by-step explanation:
a. Let x represent the number of apricot bars and y represent the number of cranberry bars. A apricot bar costs 0.80 each and cranberry bars cost 1.25 each. So the expression for the income is 0.8x+1.25y.
b. To find the answer, plug in values to the previous expression. Since Kayley bought 4 apricot bars and 2 cranberry bars, plug in 4 for x and 2 for y.
0.8(4)+1.25(2)= 5.70
So, she spent $5.70.

The radius of a sphere is 5.6 m.
It is required to find the volume of the sphere.
The formula for the volume of sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3[/tex]
r = 5.6 m
[tex]V=\dfrac{4}{3}\times 3.14\times (5.6)^3\\\\V=735.24\ m^3[/tex]

Ordered pair of Y=2x-3 , Y=-2x+5
Answer:
(2, 1 )
Step-by-step explanation:
Given the 2 equations
y = 2x - 3 → (1)
y = - 2x + 5 → (2)
Substitute y = 2x - 3 into (2)
2x - 3 = - 2x + 5 ( add 2x to both sides )
4x - 3 = 5 ( add 3 to both sides )
4x = 8 ( divide both sides by 4 )
x = 2
Substitute x = 2 into either of the 2 equations for corresponding value of y
Substituting into (1)
y = 2(2) - 3 = 4 - 3 = 1
Solution is (2, 1 )
