write an inequality for the given graph
find the length of the segment pls help
Answer: 5.1
Step-by-step explanation:
pythagorean theorem: a^2+b^2=c^2
c^2-b^2=a^2 (switch around some things)
(14.9)^2 - (14)^2 = x^2 (insert values) c=14.9,b=14,a=x
222.01 - 196 = x^2
26.01 = x^2
5.1 = x
Answer:
x = 5.1
Step-by-step explanation:
The radius of the circle is 14.9
Using Pythagoras' identity in the right triangle on the left where the hypotenuse is the radius
x² + 14² = 14.9²
x² + 196 = 222.01 ( subtract 196 from both sides )
x² = 26.01 ( take the square root of both sides )
x = [tex]\sqrt{26.01}[/tex] = 5.1

Step-by-step explanation:
When multiplying a negative number by a positive number, you multiply the numbers normally and then add on a negative sign. When dealing with signs in multiplication/division, two positives make a positive, two negatives make a positive, and one negative and one positive make a negative.

Ms. Brodie drew these box-and-whisker plots to represent her students' scores on the mid-year test and the final exam.
What do the plots tell you about the test scores of Ms. Brodie's class?
Answer:
The scores of the final exam are, in general, lower than the scores in the mid-term exam.
Step-by-step explanation:
First a little description of these graphs.
The first interval (only a line) represents the bottom 25% of the sample.
The second interval (the left part of the rectangle) represents the lower quartile, which is another 25% of the sample.
The third interval, the right part of the rectangle, represents the upper quartile, which is another 25% of the sample.
And the final segment represents the top 25%.
Looking at the first graph, we can see that the worst scores (for the bottom 25%) are between 44 and 63.
While in the second graph, the wors scores are between 44 and 59, this means that we have more people with bad scores in the final exam.
Now if we look at the lower quartile in the first graph, we can see that the range of scores is between 63 and 74.
While in the second graph the range is between 59 and 71.
Again, we can see that in the final exam the scores dropped a bit in this quartile.
In the upper quartile, we have a similar case.
In the first graph, the scores go between 74 and 81, while in the second graph the scores go between 71 and 79.
And in the final segment, we also can see a drop in the scores, because in the first graph the range is from 81 to 93
while in the second graph the range is from 79 and 92.
So in all the "segments", we can see that the scores dropped. And this is the only conclusion we can make from the graphs, the scores of the final exam are, in general, lower than the scores in the mid-term exam.

Answer:
part a:
x lengths = 6
unit lengths = 2
part b:
6x+2
Step-by-step explanation:
You add the like terms, in this case, there are 6 x, so we have 6x, and two 1s, so 1+1= 2, and since 6x and 2 are not like terms, we can't add them, making our answer 6x+2
Answer:
Im past this subject, so this is what I remember. There are six x lengths, and I believe there are 2 NOT 8 unit lengths. For B the answer is 6x+2. Dont worry about the Brainly.

Answer:
h = 4.5 units
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here A = 6.75 and b = 3 , then
[tex]\frac{1}{2}[/tex] × 3h = 6.75
1.5h = 6.75 ( divide both sides by 1.5 )
h = 4.5
we have
base [b]=3 units
height [h]=x units
area of triangle =6.75 square units
we have
area of triangle =1/2 b×h
6.75 square units =1/2×3×x
x=6.75×2/3=4.5units
so height is 4.5 units.

A soccer dome shaped like a hemisphere has a volume of 450,000 m^3. What is the area of its field? Use 3.14 for pi
Answer:
Step-by-step explanation:
450,000=2/3(3.14)r
450,000 times 3/2=2/3(3.14)r times 3/2
675,000=3.14r
675,000/3.14=3.14r/3.14
about 214968.15287=r
So now we know r. We can use it to find the area of the circle
Pi times r squared
3.14 times 214968.15287 squared
area equals about 15573.44815
The area of the hemisphere is 45065.41
How to determine the area?The given parameters are:
Shape = Hemisphere
Volume = 450000
The volume is calculated as:
Volume = 2/3pi r^3
This gives
450,000=2/3 * 3.14 * r^3
Solve for r^3
r^3 = 450000 * 3/(2 * 3.14)
This gives
r^3 = 214968.152
Take the cube roots
r = 59.9
The area is then calculated as;
Area = 4pi r^2
This gives
Area = 4 * 3.14 * 59.9^2
Evaluate
Area = 45065.41
Hence, the area of the hemisphere is 45065.41

1. What is the equation of a parabola that has a vertex at (-2, 4) and goes through the point (0,8)?
Answer:
y - k = (x + 2)^2
Step-by-step explanation:
The vertex equation of a vertical parabola is
y - k = a(x - h)^2, where (h, k) is the vertex.
We are given h = -2, k = 4, x = 0 and y = 8 and need to find the value of a.
8 - 4 = a(0 + 2)^2, or
4 = 4a, so a must be 1.
Then the desired equation is:
y - k = (x + 2)^2

Vera and her three sisters received the same amount of money to go to the school festival. Each girl spent $12. Afterward, the girls had $24 altogether.
Which equation can be used to determine the amount of money, m, each girl received?
Multiple choice question.
Answer:
Each girl (m) had $18.
Step-by-step explanation:
They each had $18.Then, they each spent $12.So, they each have $6; 6x4 = $24 leftThe Equation to determine the amount of money, m, each girl received is 4m = 72 or m = 12(4) + 24
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Each girl spent $12.
Afterward, the girls had $24 altogether.
let each Girl received amount of $x.
So, the four spend = 12 x 4 = $48
Then, the total they have = 48 + 24 = $72
So, each of Girl have = 72/ 4 = $18.

The endpoints of the directed line segment AB are A(−3, 4) and B(5, 10). Find the coordinates of point P along AB¯¯¯¯¯¯¯¯ so that the ratio of AP to PB is 1 to 3.
Answer:
The coordinates of P is (-1,5.5)
Step-by-step explanation:
Here, we want to find the coordinates of the point that divides the segment into the ratio 1 to 3
To do this, we are going to use the section formula
We have this as;
(x,y) = (nx1 + mx2)/m+ n, (ny1 + my2)/m + n
where m = 1 , n = 3
(x1,y1) = (-3,4)
(x2,y2) = (5,10)
Substituting these values, we have;
(x,y) = (3(-3) + 1(5)/4 , (3(4) + 1(10)/4
(x,y) = (-9+ 5)/4 , (12 + 10)/4
(x,y) = (-1, 5.5)

The scatter plot shows the relationship between the test scores of a group of students and the number of hours they play computer games in a week:
On a grid, Label Hours Playing Computer Games on x axis and Test Scores on y axis. The title of the graph is Test Scores and Computer Games. The scale on the x axis shows the numbers from 0 to 10 at increments of 1, and the scale on the y axis shows numbers from 0 to 100 at increments of 10. Dots are made at the ordered pairs 0, 90 and 0, 100 and 0.5, 89 and 1, 81 and 1, 95 and 1, 100 and 1.1, 85 and 2, 90 and 3, 81 and 3.5, 65 and 3.5, 75 and 5, 70 and 6, 55 and 6.5, 65 and 7, 52 and 7.5, 95 and 9, 65. The ordered pair 7.5, 95 is circled and labeled as B. All the other points are put in an oval and labeled as A.
Part A: What is the group of points labeled A called? What is the point labeled B called? Give a possible reason for the presence of point B. (5 points)
Part B: Describe the association between students' test scores and the number of hours they play computer games. (5 points)
Part A: Group A is a cluster of points. Group B Is not even a group this point is an outlier. A possible reason Point B is involved is because there could be a student that although played a lot of video games, he studied too and got a good score.
Part B: The association is a negative linear association. Also as students play more video games the test scores tend to go down.
Hope This Helps!
Answer:
Part A: A is a cluster and B is an outlier. I think it is there to show that even kids who play lots of games can get good grades.
Part B: So, if they play too many games, the grades go down, but not all the time
