In geometry, a line segment is bordered by two distinct points on a line. Or we can say a line segment is a portion of the line that connects two points.
The length of the line segment does not differ and the distance between them does not change. The units in which a line can be estimated are centimetres, millimetres, meters, inches, or feet.
A closed-line segment has both endpoints, whereas an open-line segment has two endpoints. A line segment that has only one endpoint is known as a half-open line segment.
A line segment with two endpoints P and Q and is denoted by the bar symbol (—).

471 / 33 = 14.3 (rounded)Find the explicit formula for an arithmetic sequence with a common difference of 8 and whose first term is -2.
The explicit formula of the sequence is aₙ = -10 + 8n
How to determine the explicit formula of the sequence?From the question, we have the following sequence that can be used in our computation:
The first term and the common difference
These values of the first term and the common difference are given as
First term = -2
Common difference = 8
The interpretation of the above sequence is that the 8 is added to the previous term to get the current term
Using the above as a guide,
So, we have the following representation
aₙ = aₙ₋₁ + 8
When represented explicitly, we have
aₙ = a + (n - 1) * d
Where
a = -2 and d = 8
Substitute the known values in the above equation, so, we have the following representation
aₙ = -2 + (n - 1) * 8
Evaluate the products
aₙ = -2 + 8n - 8
Evaluate the like terms
aₙ = -10 + 8n
Hence, the explicit formula is aₙ = -10 + 8n

if pam makes 250 dollars from making 15 pots, what is her piece rate?
Pam's piece rate is $16.67 for every pot she produces.
What is the rate?A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.
Pam's piece rate is the amount of money she earns for each pot she makes. In this case, she earned $250 for making 15 pots, so her piece rate is:
$250 ÷ 15 pots = $16.67 per pot
Therefore, Pam earns $16.67 for each pot she makes. This is a way of calculating her pay based on the number of units she produces, rather than by the hour.

Using the least common denominator rename 3/5 and 1/20
Answer:
12/20 and 1/20.
Step-by-step explanation:
The least common denomiator between 3/5 and 1/20 is 20.
For the first equation, we multiply the numerator and denominator by 4 to get 12/20.
The second equation's denominator is already 1/20, so we can leave it as is.
The final answer is 12/20 and 1/20.

Slope = rise / run = 2 / 3
Because points A, B, C, and D are collinear (meaning on the same line), the slope for line segment AB is the same as the slope for segment DC.
Answer:
2/3.
Step-by-step explanation:
The 2 triangles are similar so their corresponding sides are in same ratio.
The sides BA and CD are collinear so theire slopes are the same.
Slope of BA = rise/run = 2/3 so slope of DC is also 2/3.

Answer:
24
Step-by-step explanation:
Any work inside parentheses must be done first: (5^2 - 10). Also:
Exponentiation is done before addition/subtraction: 5^2 - 10 = 25 - 10 = 15
So now we have 15 / 5 * 2^3 and recognize exponentiation again:
15 / 5 * 8
Then, since multiplication and division have the same order of priority,
carry out the division in 15/5 and then multiply the result (3) by 8
to obtain 24 (final answer)
Each root of x^2 - bx + c = 0 is decreased by 2. The resulting equation is x^2 - 2x + 1 = 0, then
(a) b= 6 , c = 9 (b) b = 3 , c = 5
(c) b=2 , c = -1 (d) b = -4 , c = 3
When the root of x²-bx+c = 0 is decreased by 2, the resulting equation is x²-2x+1, then b = 2 and c = 1
What is root of quadratic equation?The values of variables satisfying the given quadratic equation are called its roots.
if the roots of a quadratic equation ax²+bx+c = 0 are alpha and beta
alpha + beta = -b/a and
alpha × beta = c/a
when the roots are reduced by 2
alpha-2+ beta-2 = -b/a
(alpha+beta)-4 = -b/a
alpha+ Bata = -b/a + 4
the resulting equation is x²-2x+1 = 0
a = 1, b = -2 and c = 1
therefore alpha +beta = -b/a = -(-2)/1 = 2
therefore 2 = -b/a+4
a = 1
2 = -b+4
b = 4-2 = 2
alpha×beta = c/a = 1/1
(alpha -2)× ( beta -2) = (alpha)( beta) -2(alpha+beta) + 4 = 1-2(2)+4 = 1
therefore b = 2 , c = 1

Find the area of the following trapezoids b1=8 cm, b2=15 cm, h=11 cm
Answer:
126.5 cm2
Step-by-step explanation:
First, the equation to find the area of a trapezoid is A= 1/2(b1 + b2)h , where b1 is the first length and b2 is the second length and h is the height. For these measurements, you would simply factor them into the equation- A= 1/2(8 + 15)11. Then using pemdas, 8+15= 23... multiplied by 1/2 equalling 11.5. Then multiply 11.5 by 11 to get your answer of 126.5 then add the units.

anna bought 20 christmas raffle tickets in her school. Her school sold 1500 tickets in all. What is the probability of the winning chances of anna?
The probability of Anna winning chances of buying 20 ticket out of 1500 tickets is 0.013.
What is probability?Probability simply means possibility. It deals with how likely something is to happen.
Therefore,
p(A) = number of favorable outcomes to A / total number of outcome
Hence,
Number of ticket bought by Anna = 20
Total ticket sold = 1500
Therefore,
probability of the winning chances of Anna = 20 / 1500
probability of the winning chances of Anna = 2 / 150
probability of the winning chances of Anna = 1 / 75
probability of the winning chances of Anna = 0.013

What is the radius of a hemisphere with a volume of 38153 in”, to the nearest tenth

Answer:
26.3
Step-by-step explanation:
Delta Math
The radius of a hemisphere with a volume of [tex]38153[/tex] in", to the nearest tenth of an inch is [tex]26.3[/tex].
What is radius?A circle's or sphere's radius is any line segment that connects the object's centre to its perimeter in classical geometry; in more contemporary usage, it is also the length of those line segments.
The word "radius" is derived from the Latin word "radius," which also refers to the spoke of a chariot wheel. Use the equation [tex]r =\frac{D}{2}[/tex] to determine the radius, which is equal to half the diameter. This is the same process used to determine a circle's radius from its diameter.
A hemisphere's volume is equal to [tex]\frac{2}{3} \pi r^3[/tex] cubic units. Where is an estimated constant with a value of [tex]3.14[/tex]. The hemisphere's radius is denoted by "r."
Required calculations are:
V = r
r = radius.
Given, V = 38153 in³
[tex]38153 = \frac{2}{3} \pi r^3[/tex]
[tex]r^3 = \frac{3 \times 38153}{2 \times \pi }[/tex]
[tex]r = 3\sqrt{\frac{3 \times 38153}{2 \times \pi }}[/tex]
r =26.3 in
Therefore, the radius of a hemisphere with a volume of [tex]38153[/tex] in", to the nearest tenth of an inch is [tex]26.3[/tex].
