Answer: x = 2

Step-by-step explanation: 5x + 8 = 2x + 14

                                             5x + 8 - 2x = 2x + 14 - 2x

                                             3x + 8 - 8 = 14 - 8

                                             3x = 6

                                             3x/3 = 6/3

                                             x = 2

For this problem, x would equal 2.

The true statements about the dot plots are:

B. Eagles have more variability (5)

D. The Eagles have more players (14)

Variability is a measure of the degree to which the data values vary from the average value. In a dot plot, the range (max value - min value) is a measure of variability. The larger the range, the more the variability.

Range for age of the 14 players of eagles = 12 - 7 = 5

Range for age of the 13 players of lions = 12 - 9 = 3

Lines in the same plane that intersect to form a 90 degree angle

Step-by-step explanation:

Final answer:

Parallel lines in Euclidean geometry are lines in the same plane that never intersect, maintaining a consistent distance from each other. The parallel postulate ensures the uniqueness of parallel lines through a given point relative to a line.

Explanation:

Parallel lines are defined as lines in the same plane that never intersect no matter how far they are extended in either direction. This concept is a fundamental part of Euclidean geometry, and it is also important in understanding the basis of linear perspective, where parallel lines appear to converge as they recede into the distance.

Moreover, while discussing the relationship between planes and lines, if three nonparallel planes are considered, they typically intersect in a single unique point or along a single line, depending on their orientation and equations. In contrast, parallel lines would not provide such a point or line of intersection since they never meet.

Answer:

A. 20°

Step-by-step explanation:

ΔABC's full internal angle measurements = 180°

m∠CAB = 80°

m∠ACB = 50°

m∠DBA = 30°

m∠DBC = ?

Add the measurements of the angles together, and subtract from the total:

m∠DBC = 180 - (80 + 50 + 30)

m∠DBC = 180 - (160)

m∠DBC = 20°

A. 20° is your answer.

~

Answer:

∠DBC = 20°

Step-by-step explanation:

∠A + ∠C + ∠ABC = 180   { sum of all angles of triangle}

50 + 80 + ∠ABC = 180

130 +∠ABC = 180

∠ABC  = 180 - 130

∠ABC = 50°

∠ABD + ∠DBC = ∠ABC

30 + ∠DBC = 50

∠DBC = 50 - 30

∠DBC = 20°

Answer:

25.133

Step-by-step explanation:

area is pi*r^2. divide area by 3.14 and then sqrt to find radius. 6.28*radius= circumference, so 6.28*4=25.133

Answer:

25.12

Step-by-step explanation:

1. Use the formula for the area of a circle to find the radius

[tex]A=\pi r^2[/tex]

[tex]50.24=\pi r^2[/tex]

[tex]16=r^2[/tex]

[tex]\sqrt{16} =r[/tex]

[tex]4=r[/tex]

2. Use this value to find the circumference

[tex]C=2\pi r[/tex]

[tex]C=2\pi 4[/tex]

[tex]C=2(12.56)[/tex]

[tex]C=25.12[/tex]

Answer:

-4x + 5

Step-by-step explanation:

to be parallel, you need the same slope,

so it has to be -4x

and to go through the point (1,1) the y intercept has to be 5

because if you are using that slope, going down four and over one starting at (0,5) will connect the line to (1,1)

If it helps to draw it out or somehow visually see it, that would be a great idea

but in sum, the only answer is  y = -4x + 5

(i didn't see someone had already answered)

(but the answer above uses the slope of 2x and I am unsure why because it says -4x on your question)

(so I guess you could just look at both and see what you need :))

Step-by-step explanation:

Step 5 is to ( C ) take the Square root of both sides

The radius of the cone is ( A ) 2 inches

The radius of the cone is 2 inches.

The volume of a cone is determined by the amount of space occupied by the cone. A three-dimensional figure having a single circular base is known as a cone. The base and the vertex are connected by a curved surface. A cone with a radius of r has a volume V that is one-third the area of the base B times the height h.

[tex]V=\frac{1}{3} \pi r^{2} h[/tex] or [tex]V=\frac{1}{3} Bh[/tex],

Since, [tex]B=\pi r^{2}[/tex]

Given that the volume of cone V is 48π cubic inches and Height of the cone h=36 inches.Volume of cone [tex]V=\frac{1}{3} \pi r^{2} h[/tex] -------1

Here, the base of the cone is circular in shape and the area of circle is [tex]\pi r^{2}[/tex]. Consider [tex]B=\pi r^{2}[/tex]

Substituting the area of base in the equation (1).

[tex]V=\frac{1}{3} \pi r^{2}[/tex]

    [tex]= \frac{1}{3} Bh[/tex]

Substitute the given values in the equation (1).

⇒ [tex]48\pi =\frac{1}{3} \pi r^{2} 36[/tex]

⇒ [tex]\frac{48\pi }{36\pi } =\frac{r^{2} }{3}[/tex]

⇒ [tex]\frac{12(3)}{9}=r^{2}[/tex]

⇒[tex]4=r^{2}[/tex]

⇒ [tex]r=2[/tex]

Thus, the radius of the cone is 2 inches.

The green area in the figure above represents a section of grass for a putting green. Find the area of the sector of grass.

A. A= 32π ft²

B. A= 6π ft²

C. A= 36π ft²

D. A= 72π ft²

Answer:

C. A= 36π ft²

Step-by-step explanation:

The image below is where your question emanated. The area of the sector of grass can be calculated below.

Area of a sector = ∅/360 × πr²

where

∅ = angle from the center of the circle

r = radius

Area of a sector = ∅/360 × πr²

r = 12 ft

∅ = 90°

Area of a sector = 90/360 × π × 12²

Area of a sector = 90/360 × π × 144

Area of a sector = 1/4 × 144π

Area of a sector = 144π/4

Area of a sector = 36π ft²

Answer: third option

Step-by-step explanation:

The total surface area to be painted in the hotel room is 644 square feet.

To calculate the surface area of the walls and the ceiling to be painted in a room, we separate the two calculations since the walls and the ceiling have separate dimensions. The floor of the room is a 14-foot square, which means that each side of the wall is 14 feet long. The ceiling also has the same dimensions as the floor. The room has a height of 8 feet.

The area of the ceiling is equal to the area of the floor since they are both squares with the same side length, which is calculated as follows:

Area of ceiling = Side length × Side length

Area of ceiling = 14 feet × 14 feet = 196 square feet

Next, we calculate the surface area of the walls. There are four walls in the room, and each wall has the same height of 8 feet. The wall area is calculated as follows:

Area of one wall = Side length × Height

Area of one wall = 14 feet × 8 feet = 112 square feet

Since there are four walls, total wall area = 4 × 112 square feet = 448 square feet

Finally, we add the area of the ceiling to the total wall area to get the total surface area to be painted:

Total surface area = Ceiling area + Wall area

Total surface area = 196 square feet + 448 square feet = 644 square feet

Therefore, the total surface area of the walls and ceiling of the room that will be painted is 644 square feet, ignoring any doors or windows.

(x - 2)

Step-by-step explanation:

Given

x² - 9x + 14

Consider the factors of the constant term (+ 14) which sum to give the coefficient of the x- term (- 9)

The factors are - 2 and - 7, since

- 2 × - 7 = + 14 and - 2 - 7 = - 9, thus

x² - 9x + 14 = (x - 2)(x - 7) ← in factored form

Thus (x - 2) is a factor of the expression

Answer:

8 dollars

Step-by-step explanation:

The required selling price of an item that has originally price $80 is $27.89.

Given that,
Each Saturday, a store reduces the price of any unsold item by 10%.
An item was priced at $80, on Saturday of the first week it is marked down to $72.
At the end of the second week, it drops to $64.80, and at the end of the third week, the price is decreases to $58.32.  
This continues for 10 weeks.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
From the given,
The relation is given as,
Selling price = original price [1 - 0.10]ˣ
Substitute the value in the above equation,
selling price = 80 [0.9]¹⁰
The selling price = $27.89

Thus, the required selling price of an item that has an original price $80 is $27.89.

=====================================================

Work Shown:

E = exterior angle

n = number of sides

For any regular polygon, E = 360/n.

In this case, n = 10 as there are 10 sides, so E = 360/n = 360/10 = 36 degrees is the measure of each exterior angle.

Each interior angle is 180-E = 180-36 = 144 degrees

--------------

An alternative is to plug n = 10 into the formula below to get the measure of each interior angle i

i = 180(n-2)/n

i = 180(10-2)/10

i = 180(8)/10

i = 1440/10

i = 144

note: S = 180(n-2) is the sum of all the interior angles of any convex polygon. Dividing this sum over n will evenly divide the angle total to each interior angle.
