Answer:
The length of BC is 48 units.
Step-by-step explanation:
Given information: Line g bisects line segment BC at Point H. BH = 4x and HC = 24.
It is given that line g bisects line segment BC at Point H. It means point H divides the line BC in two equal parts BH and HC.
[tex]BH=HC[/tex]
[tex]4x=24[/tex]
Divide both sides by 4.
[tex]x=6[/tex]
The value of x is 6.
[tex]BH=4x=6\times 4=24[/tex]
The length of BC is
[tex]BC=BH+HC[/tex] (Segment addition property)
[tex]BC=24+24=48[/tex]
Therefore the length of BC is 48 units.

he coordinates of the vertices of a polygon are (−2,−2), (3,−3), (4,−6), (1,−6), and (−2,−4).
What is the perimeter of the polygon to the nearest tenth of a unit?
Answer:
16.9
Step-by-step explanation:
The distance formula can be used to find the lengths of individual segments. It tells you ...
d = √((Δx)² +(Δy)²)
where Δx and Δy are the differences between x- and y-coordinates of the segment end points.
Since the value is squared, the sign of the difference doesn't matter. It can be easier to write it as always positive, so in some cases it may be Δx = x₂-x₁ and in other cases it might be Δx = x₁-x₂, for example.
If the segments are labeled A, B, C, D, E in order, the distances are ...
AB = √(5²+1²) = √26 ≈ 5.099
BC = √(1²+3²) = √10 ≈ 3.162
CD = Δx = 3
DE = √(3²+2²) = √13 ≈ 3.606
EA = Δy = 2
Then the perimeter is ...
P = AB +BC +CD +DE +EA = 5.099 +3.162 +3 +3.606 +2 = 16.867
P ≈ 16.9

A bag contains 8 blue marbles, 5 green marbles and 7 red marbles. If Alicia removes two marbles without replacing them, what is the probability that he will choose red, then green?
To find the probability of choosing a red marble, then a green marble without replacement, multiply the probabilities of the individual events which is 7/76.
Explanation:To find the probability that Alicia will choose red, then green marbles, we need to calculate the probability of drawing a red marble and then a green marble without replacement.
Given that there are 8 blue marbles, 5 green marbles, and 7 red marbles in the bag, the probability of drawing a red marble first is 7/20.
After removing the red marble, there are 19 marbles left in the bag, including 5 green marbles. Therefore, the probability of drawing a green marble second is 5/19.
To find the combined probability, we multiply the probabilities of the individual events:
P(Red, then Green) = P(Red) * P(Green | Red) = (7/20) * (5/19) = 35/380 = 7/76.

On an algebra test , the highest grade was 42 points higher than the lowest grade . The sum of the two grades was 138 . Find the lowest grade .
The lowest grade is 48.
What is substitution method?The substitution method is the algebraic method to solve simultaneous linear equations. In this method, the value of one variable from one equation is substituted in the other equation.
Let the lowest grade be x and highest grade be y.
According to the given question.
[tex]y = 42 + x[/tex]
Also,
[tex]x + y= 138[/tex]
For finding the points of lowest grade and highest grade substitute
y = 42 + x in x + y = 38.
[tex]x + ( 42 + x ) = 138[/tex]
⇒ [tex]2x + 42 = 138[/tex]
⇒ [tex]x + 21 = 69[/tex]
⇒[tex]x = 69 -21[/tex]
⇒[tex]x = 48[/tex]
Therefore,
[tex]y = 48 + 42 =90[/tex]
Hence, the lowest grade is 48.

Which function represents the graph of f(s)=-4[x] after it is translated 3 units down?
Given the functions f(x) = 2x2 - 8x, g(x) = x2 - 6x + 1, and h(x) = -2x2, rank them from least to greatest based on their axis of symmetry. (2 points)
g(x), f(x), h(x)
f(x), g(x), h(x)
h(x), f(x), g(x)
h(x), g(x), f(x)
Answer:
h(x), f(x) , g(x)
Step-by-step explanation:
[tex]f(x) = 2x^2 - 8x[/tex]
Axis of symmetry at [tex]x=\frac{-b}{2a}[/tex], a=2, b=-8
[tex]x=\frac{-b}{2a}[/tex]
[tex]x=\frac{-(-8)}{2(2)}=2[/tex]
[tex]g(x) = x^2 - 6x + 1[/tex], a= 1, b=-6
[tex]x=\frac{-b}{2a}[/tex]
[tex]x=\frac{-(-6)}{2(1)}=3[/tex]
[tex]h(x) = -2x^2[/tex], a=-2, b=0
[tex]x=\frac{-b}{2a}[/tex]
[tex]x=\frac{-(0)}{2(-2)}=0[/tex]
Now rank the function based on their axis of symmetry

What is the distance between points A and B?
___ units
we know that
the distance's formula between two points is equal to
[tex]d=\left|xB-xA\right|[/tex]
substitute
[tex]d=\left|1-(-5)\right|[/tex]
[tex]d=6\ units[/tex]
therefore
the answer is
[tex]6\ units[/tex]
The distance between two point [tex]A{\text{ and }}B[/tex] is [tex]\boxed{{\mathbf{6 units}}}[/tex].
Further explanation:
The distance between two points is the modulus of difference of the given two points.
The distance between two points can be found by the distance formula as,
[tex]\left| {B - A} \right|[/tex]
Here, [tex]A{\text{ and }}B[/tex] are the points on the number line.
The distance cannot be negative therefore modulus is applied in the formula.
Step by step explanation:
Step 1:
First we determine the points from the given number line.
It can be observed from the given number line that there are two points one is on the left side of the origin and the second is right side of the origin.
The point [tex]A[/tex] is [tex]- 5[/tex] and the point [tex]B[/tex] is 1.
Step 2:
Now use the distance formula to obtain the distance between the two points [tex]A{\text{ and }}B[/tex].
Here, the value of A is [tex]-5[/tex] and B is 1.
Substitute the value of [tex]A{\text{ and }}B[/tex] to obtain the distance as,
[tex]\begin{aligned}d&= \left| {B - A} \right| \\&= \left| {1 - \left( { - 5} \right)} \right|\\&= 6{\text{ units}}\\\end{aligned}[/tex]
Therefore, the distance between two point [tex]A{\text{ and }}B[/tex] is [tex]6{\text{ units}}[/tex].

One car rental company charges $30 per day plus $0.25 per mile driven. a car company charges $40 per day plus $0.10 per mile driven. how many miles must you drive for a one-day rental at the second company to be less expensive than the same rental at the first company? write an inequality to solve.
Answer:
66.667 miles
Step-by-step explanation:
Given: One car rental company charges $30 per day plus $0.25 per mile driven.
Second car company charges $40 per day plus $0.10 per mile driven.
To find: how many miles must you drive for a one-day rental at the second company to be less expensive than the same rental at the first company?
Solution: Let the distance driven on a day be x miles.
As per question,
The first rental company will charge [tex]=30+0.25x[/tex]
The second rental company will charge [tex]=40+0.10x[/tex]
Now, we want the rental charges of second company to be less expensive then the first.
So we get the inequality,
[tex]30+0.25x>40+0.10x[/tex]
[tex]0.25x-0.10x>40-30[/tex]
[tex]0.15x>10[/tex]
[tex]x>\frac{1000}{15}[/tex]
[tex]x>66.667[/tex] miles
Hence, at least 66.667 miles should be driven on a day.
