Points A, B, and C are collinear and B is between A and C. You are given AC = 18 and BC = 4. What is the value of AB?
Answer:
The value of AB is 14
Step-by-step explanation:
When we say a set of points are collinear, what we mean is that those points are on the same straight line i.e they lie on a straight line.
Now B is between A and C
Since B is between A and C
Then mathematically;
AC = AB + BC
18 = AB + 4
AB = 18-4
AB = 14
Based on the segment addition theorem, the value of AB would be: 14.
What is Segment Addition Theorem?Given that three points, A, B, and C are collinear, where b is between points A and C, the segment addition theorem states that, AB + BC = AC.
Given:
AC = 18BC = 4AB = ?Thus:
AB + 4 = 18 (segment addition theorem)\
AB = 18 - 4
AB = 14
Thus, based on the segment addition theorem, the value of AB would be: 14.

Answer:
500/3.
Step-by-step explanation:
4(t+25)=4(t+50)−4(0.15t)
4t + 100 = 4t + 200 - 0.6t
Subtract 4t from both sides
100 = 200 - 0.6t

Which function does the graph represent? f(x) = (x + 3)(x + 7) f(x) = (x – 3)(x – 7) f(x) = 3(x – 3)(x – 7) f(x) = 11(x + 3)(x + 7)
This question is incomplete because it lacks the picture of the graph. Find attached to the answer, the picture of the graph.
Question:
Which function does the graph represent?
a) f(x) = (x + 3)(x + 7)
b) f(x) = (x – 3)(x – 7)
c) f(x) = 3(x – 3)(x – 7)
d)f(x) = 11(x + 3)(x + 7)
Answer:
c) f(x) = 3(x – 3)(x – 7)
Step-by-step explanation:
The function of a graph or the the graph of a function is when
f(x) = y
From the attached graph, after reading it,
They are three specific points on the x - axis, where x = 3 and x = 7, x = 8
So, where x = 3 on the x axis, y =
f(3) = 0
where x = 7 on the x axis, y =
f(7) = 0
So, where x = 8 on the x axis, y =
f(8) = 15
Looking at the options in the question,
a) f(x) = (x + 3)(x + 7)
f(x) = y
where x= 3
f(3) = (3+3)(3+7)
= 60
where x= 7
f(7) = (7+3)(7+7)
= 140
where x= 8
f(8) = (8+3)(8+7)
= 165
This option is wrong
b) f(x) = (x – 3)(x – 7)
f(x) = y
where x= 3
f(3) = (3-3)(3-7)
= 0
where x= 7
f(7) = (7-3)(7-7)
= 0
where x= 8
f(8) = (8-3)(8-7)
= 5
This option is wrong.
c) f(x) = 3(x – 3)(x – 7)
f(x) = y
where x= 3
f(3) = 3(3-3)(3-7)
= 0
where x= 7
f(7) =3(7-3)(7-7)
= 0
where x= 8
f(8) = 3(8-3)(8-7)
= 3(5)(1)
= 15
This option is correct
d)f(x) = 11(x + 3)(x + 7)
f(x) = y
where x= 3
f(3) = 11(3+3)(3+7)
= 660
where x= 7
f(7) = 11(7+3)(7+7)
= 1540
where x= 8
f(8) = 11(8+3)(8+7)
= 1815
Therefore, function the graph represents is Option c) f(x) = 3(x – 3)(x – 7)
Answer: The answer is C. f(x)= 3(x-3)(x-7)

Uma urna contém 10 bolas identificadas pelas letras A, B, ..., J. Uma bola é extraída ao acaso da urna e sua letra é observada. (Deixe explícito o espaço amostral e todos os eventos). Qual é a probabilidade de uma letra da bola sorteada ser: a) Vogal b) Consoante
Answer:
a) Probability that a letter of the drawn ball is vowel = (3/10) = 0.30
b) Probability that a letter of the drawn ball is consonant = (7/10) = 0.70
a) Probabilidade de uma letra da bola sacada ser vogal = (3/10) = 0.30
b) Probabilidade de uma letra da bola sacada ser consoante = (7/10) = 0,70
Step-by-step explanation:
English Translation
A ballot box contains 10 balls identified by the letters A, B, ..., J. A ball is drawn at random from the ballot box and its letter is observed. (Make the sample space and all events explicit). What is the probability that a letter of the drawn ball is: a) Vowel b) Consonant
Solution
The 10 balls are identified by A, B, C, D, E, F, G, H, I and J
Note that the probability of an event is given as the number of elements in that event divided by the number of elements in the sample space.
a) Probability of drawing a ball that has a vowel letter = P(v)
P(v) = n(v) ÷ n(S)
n(v) = Number of balls with vowel letters = 3 (that is, A, E and I)
n(S) = Total number of balls = 10
P(v) = (3/10) = 0.30
b) Probability of drawing a ball that has a consonant letter = P(c)
P(c) = n(c) ÷ n(S)
n(c) = Number of balls with consonant letters = 7 (that is, B, C, D, F, G, H and J)
n(S) = Total number of balls = 10
P(c) = (7/10) = 0.70
In Portugese/Em português
As 10 bolas são identificadas por A, B, C, D, E, F, G, H, I e J.
Observe que a probabilidade de um evento é fornecida como o número de elementos nesse evento dividido pelo número de elementos no espaço de amostra.
a) Probabilidade de desenhar uma bola com uma letra de vogal = P (v)
P (v) = n (v) ÷ n (S)
n (v) = Número de bolas com letras de vogal = 3 (ou seja, A, E e I)
n (S) = Número total de bolas = 10
P (v) = (3/10) = 0,30
b) Probabilidade de desenhar uma bola com uma letra consoante = P (c)
P (c) = n (c) ÷ n (S)
n (c) = Número de bolas com letras consoantes = 7 (ou seja, B, C, D, F, G, H e J)
n (S) = Número total de bolas = 10
P (c) = (7/10) = 0,70

does anyone know the answer for top and bottom? please help
Answer:
15/18=5/6
14/18=7/9
the last symbol
Step-by-step explanation:
Answer:
For the first part (the part on the top), you have to make the fractions have the same denominator. To do this, you must find the LCM (least common multiple) of 6 and 9. The LCM of 6 and 9 would be 18 because 6x3=18 and 9x2=18. Now, both of the denominators are 18. But we still have to change the numerators! To change the numerators, we must multiply them by the same numbers that we multiplied the denominators by. So for 5/6, we would multiply the 5 (the numerator) by 3 because that is what we multiplied the 6 by. 5x3=15. So now the first fraction, 5/6, is 15/18 (that's the answer). For 7/9, we still have to multiply the 7 (the numerator) by 2. 7x2=14. So now this fraction, 7/9, is 14/18 (that's the answer).
So basically what I was saying is that 5/6=15/18 and 7/9=14/18.
For the second part (the part on the bottom), you have to compare the fractions. It is difficult right now as it is written as 5/6 and 7/9. But remember what we did for the first part! Think about these fractions as 15/18 and 14/18. 15/18 is larger than 14/18. So the answer for the part on the bottom is 5/6 > 7/9.
Hope this helps! :)

Two trains start from Fort Worth traveling at the same speed. The trip for Train W takes 20 hours, while the trip for Train Z takes 25 hours. If the city Train Z is traveling to is 400 miles farther away than the city Train W is traveling to, how far will Train Z travel in total to reach its destination?
a) 1,200 miles
b) 480 miles
c) 2,400 miles
d) 2,000 miles
e) 1,600 miles
Answer:
The equation that best models this situation is : b.
Distance traveled by Train W = 1600 miles
Distance traveled by Train Z = 2,000 miles
Step-by-step explanation:
Given:
Time taken for Train W to complete a trip = 20 hours
Time taken for Train Z to complete a trip = 25 hours
The city Train Z is traveling to is 400 miles farther away than the city Train W is traveling to.
both trains have same speeds and start from same location.
To find the distance in total each train travels.
Solution:
Let length of the trip of Train W be = miles
Speed of Train W can be given as :
⇒
⇒
So, the length of the trip of Train Z will be = miles
Speed of Train Z can be given as :

What is the domain of the function f(x)=x^2+3x+5?
OA
all whole numbers
OB.
all positive real numbers
O c. all integers
OD. all real numbers
Answer:
all real numbers
Step-by-step explanation:
Answer:
The domain of this function is all real numbers
Step-by-step explanation:
Unless there is a domain restriction for the function, the domain of a function is all real numbers. This means that all we need to do is determine whether there is a domain restriction.
The things that cause a domain restriction are: an x in the denominator of a fraction like [tex]f(x)=\frac{1}{x}[/tex] or a radical like [tex]f(x)=\sqrt{1-x}[/tex]
As there are no variables in the denominator or a radical, we can conclude that the domain of this function is all real numbers.

An ice cream shop sells cones in two sizes.
A large cone has a diameter of 3 inches
and a height of 5 inches while a small
cone has a diameter of 2 inches and a
height of 5 inches. Find the difference in
volume of the cones to the nearest
tenth.
SOLUTION:
HOW DO YOU KNOW?
Y’all I need help ASAP!! All work is due at 12am and I can’t fail.
Answer: The difference is 6.5 inches.
Step-by-step explanation:
The volume of a cone uses the formula V= nr^2 h/3
So the large cone's volume is V= 3.14 * 1.5^2 *5/ 3
v= 11.775
The volume of the small cone is V= 3.14 * 1^2* 5/3
V=5.23
Now find the difference. 11.775 - 5.23= 6.54
Round to the nearest tenth is 6.5

This question is incomplete.
Complete question
This composite figure is made of two identical pyramids attached at their bases. Each pyramid has a height of 2 units.
2 identical pyramids with rectangular bases are connected at their base. The height of the pyramid is 2. The lengths of the sides of the rectangle are 5 and 0.25 units.
Which expression represents the volume, in cubic units, of the composite figure?
Answer:
2(1/3(5)(0.25)(2))
Step-by-step explanation:
The volume of a rectangular pyramid is given as
1/3 × (Area of the base rectangle ) × Height
Area of the base rectangle = Length × Width
We are told in the question that:
The lengths of the sides of the rectangle are 5 and 0.25 units.
Area of the base rectangle = 5 units × 0.25 units
The height of the pyramid = 2 units
Therefore, the volume of the rectangular pyramid = 1/3× (5×0.25) × 2
We are also told in the question that this composite figure is made of two identical pyramids attached at their bases.
Therefore, expression that represents the volume, in cubic units, of the composite figure is given as:
2(1/3× (5×0.25) × 2) = 2(1/3(5)(0.25)(2))
1. The measure of angle GHI is 120°. Angle GHI is cut in half with ray HK, if angle
GHK is 3x + 48 , what is the value of x?
Answer:
Step-by-step explanation:
Ray HK is an angle bisector, which means that it cuts the angle exactly in half. So half of GHI is 60. If GHK is 3x + 48, and that is half of angle GHI. then
3x + 48 = 60 and
3x = 12 so
x = 4

An airplane took off and flew at an angle of elevation 12° with the ground. What was the approximate altitude of the airplane, (high how is the plane directly from the ground), after it had flown 8,000 meters (hypotenuse)?
Answer:
1663 m approx.
Step-by-step explanation:
We have a right triangle in which we know the hypotenuse and need to find the opposite side, so we use the sine function:
sin 12 = h / 8000
h = 8000 sin 12
= 1663 m approx.
