Answer:
Formula Of Vertex and Line of symmetry
Step-by-step explanation:
The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a
Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex"

Henry has a bag containing 39 letter tiles, some consonants, and some vowels. He selects a tile without looking and then replaces it. If he pulls 7 consonant tiles and 6 vowel tiles, which is the most likely number of consonant tiles in Henry's bag?
Answer:
21 consonant tiles
Step-by-step explanation:
Henry has a bag containing 39 letter tiles, some consonants, and some vowels.
He selects a tile without looking and then replaces it. If he pulls 7 consonant tiles and 6 vowel tiles, which is the most likely number of consonant tiles in Henry's bag?
Step 1
We add up the number of tiles that he pulls out of the bag
= 7 consonant tiles + 6 vowel tiles
= 13 tiles
Step 2
We divide the total number of tiles in the bag by the total number of tiles that was pulled out of the bag
= 39 tiles ÷ 13 tiles
= 3
Step 3
The most likely number of consonant tiles in Henry's bag is calculated as:
3 × The number of consonant tiles that was pulled out of the bag.
Hence:
3 × 7 consonant tiles
= 21 consonant tiles.
Therefore, the most likely number of consonant tiles in Henry's bag is 21 consonant tiles.
Is (2, -4) a solution to the inequality 2x - 3y < 15? Yes or No
Answer:
No.
Step-by-step explanation:
We substitute the values x = 2 and y = -4 into the inequality.
Left side = 2(2) - 3(-4) = 4 + 12
= 16
Now the right side is 15 so we get 16 < 15 which is incorrect.
So (2, -4) is not a solution.

10 - 10 × 10
Answer:
-90
Step-by-step explanation:
10 - 10 x 10
10 x -10 = -100 (always do multiplication first)
-100 + 10 = -90
Answer: The answer to this basic math question with a basic given math expression is -90.
Step-by-step explanation: Mmmm, that was super extremely easy, so anyways, here are 3 basic steps in order to evaluate the given basic math expression:
Step 1. First, let's input the original basic equation that looks in the basic equation form like this: [tex]10 - 10 * 10.[/tex]
Step 2. After we input the original basic equation, next, let's do the multiplication first by multiplying 10 by 10 that looks in the basic equation form like this: [tex]10 - 100.[/tex]
Step 3. Last but not least is after we multiply 10 by 10 first, finally, let's subtract 10 and 100, and therefore your answer to this basic math question with the given basic math expression is -90.
I hope that my full given answer with my full given step-by-step explanation is very helpful to your own basic math question with the given basic math expression, please take care, always be safe, and have a great rest of the holiday winter break, Merry Christmas and a happy new year! :D

The boxplot below displays the arm spans for 44
students.
The five-number summary for the data is 143, 162,
168, 180, and 202.
Which of the following is not a true statement?
Approximately 75% of the arm spans are less than
180 cm.
O Approximately 50% of the arm spans are less than
168 cm.
Approximately 25% of the arm spans are less than
180 cm.
140 150 160 170 180 190 200 210
Arm Span (cm)
O Approximately 75% of the arm spans are greater
than 162 cm.
Answer:
C
Step-by-step explanation:
I think, :)
The boxplot below displays the arm spans for 44 student . The statement that is not true from the given option is
Approximately 25% of the arm spans are less than 180 cm
Option C
Given :
The boxplot below displays the arm spans for 44 students.
The five-number summary for the data is 143, 162, 168, 180, and 202.
From the given five number summary we can see that
minimum =143
First Quartile (25%)= 162
Median (50%)= 168
Third quartile (75%)= 180
Maximum =202
Now we analyze the statements
Approximately 75% of the arm spans are less than 180 cm. Its true because third quartile is 75% that is equal to 180
Approximately 50% of the arm spans are less than 168 cm.. Yes its true because median is 168
Approximately 25% of the arm spans are less than 180 cm. It is false because first quartile 25% is 162. So , 25% of the arm spans are less than 162 cm
Approximately 75% of the arm spans are greater than 162 cm. It is true . because 25% of the arm spans are less than 162 cm

Solve this for the brainlist
Answer:
22.4
Step-by-step explanation:
using altitude theorem, the height of the triangle is 20
let y = height
10/y = y/40
y² = 400
y = [tex]\sqrt{400}[/tex] or 20
Now we can us the Pythagorean Theorem to find 'x':
10² + 20² = x²
100 + 400 = x²
x=[tex]\sqrt{500}[/tex] ≈ 22.4

Here is a story: Lin bought 4 bags of apples. Each bag had the same number of apples. After eating 1 apple from each bag, she had 28 apples left.
Which diagram best represents the story? Explain why the diagram represents it.
What part of the story does
x
represent?
Describe how you would find the unknown amount in the story
Answer:
Let's define the variable x as the number of apples in each bag.
We know that she bought 4 bags, then the total number of apples that she has is:
Apples = 4*x
Now she eats one apple for each bag, then she eats 4 apples, so she now has:
Apples = 4*x - 4
And we know that this is equal to 28, then:
4*x - 4 = 28
now we can solve this for x.
4*x = 28 + 4 = 32
x = 32/4 = 8
x = 8
There are 8 apples in each bag.
For the diagram part, by a small online search y found the image that you can see below.
The diagram that correctly represents this situation is diagram C, where x represents the number of apples in each bag.

What is the approximate volume of this tree trunk if the circumference is 26π inches and the height of the trunk is 22 inches,
Answer:
Volume = 11680.44 cubic inches
Step-by-step explanation:
Circumference of the trunk of a tree = 2πr
Here, r = radius of the trunk
26π = 2πr
r = 13 inch
Since, volume of the cylindrical trunk = πr²h
= π(13)²(22)
= 3718π
= 11680.44 cubic inches

[ASPS]WILL GIVE BRAINLIEST
Answer:
sum of exterior angles of a polygon = 360°
therefore,
x + 5 + x + 10 + 3x - 8 + 5x + 10 = 360°
10x + 17 = 360°
x + 17 = 360 ÷ 10 = 36
x = 36 - 17 = 19
x = 19
rounding off 19 to nearest hundred = 20
value of x will be 20
