From the given scatter-plot, we have that:
Point (25, 125) means that the monthly home heating bill was of $125 for a month with average temperature was of 25ºF.The plot shows that, in general, as the average monthly temperature increases, the amount of the monthly home heating bill decreases.What does a scatter plot show?A scatter plot shows a series of points (x,y), relating the input x to the output y.
For the scatter-plot in this problem, we have that:
The input x is the monthly temperature.The output y is the heating bill.The points are given as follows:
(10, 155), (30, 120), (50, 80), (70, 25), (80, 18).
When x = 25, y = 125, meaning that the monthly home heating bill was of $125 for a month with average temperature was of 25ºF.
From the points in the scatter plot, when x increases, y decreases, which is the answer for the second item of the question. It makes sense, as when it is hotter, the spending in heaters is unnecessary.

The Segment Addition Postulate states if three points J, K, and L are collinear and J is between K and L, then KJ + JL = KL.
The segment addition postulate states that if a line segment has two endpoints, say, A and C, then a third point B will lie somewhere on the line segment AC if and only if the following equation is satisfied-
AB + BC = AC
The segment addition postulate is applicable only to a line segment, and does not apply to a ray or a line. A line segment differs from a ray or a line as it is bounded by two defined endpoints.
Here, if three points J, K, and L are collinear and J is between K and L, then as per Segment Addition Postulate-
KJ + JL = KL

How long will it take you to ski a distance of 36 miles at the speed of 5 miles per 45 minutes
To ski a distance of 36 miles at the speed of 5 miles per 45 minutes, will take 324 min
The formula and procedure we will use to solve this exercise is:
t = x/v
Where:
x = distancet = timev = velocityInformation about the problem:
v = 5 miles per 45 minutesx = 36 milest = ?Calculating the velocity we have:
v = x/t
v= 5 miles/45 min
v = 0.111 miles/ min
Applying the time formula from the uniformly rectilinear motion (URM), we have:
t = x/v
t = 36 miles/0.111 miles/ min
t = 324 min
What is velocity?It is a physical quantity that indicates the displacement of a mobile per unit of time, it is expressed in units of distance per time, for example (miles/h, km/h).

Answer the question in photo [ Brainliest + 20 points ]
Answer:
27 units
Step-by-step explanation:
First lets add the 2 segments on the top.
8x-11 + 14x-15
Then we can add the like terms together to get
22x-26
The equation above is equal to the equation below the number line, since we added the two on top together, so:
22x-26=19x-17
Now we can start solving
Add 26 to both sides and subtract 19 from both sides
3x=9
Now we can divide by 3
x=3
TU is 14x-15, so we can substitute in 3 for x
14*3-15
42-15
27
Answer:
27 units
Step-by-step explanation:
Set up an equation:
8x -11 + 14x -15 = 19x - 17
Combine like terms:
22x - 26 = 19x -17
Subtract 19x on both sides:
(22x - 26) - 19x = (19x - 17) - 19x
3x - 26 = -17
Add 26 on both sides to isolate the x term:
(3x - 26) + 26 = (-17) + 26
3x = 9
Then, divide by 3 on both sides to fully isolate x:
3x / 3 = 9 / 3
x = 3
Plug 3 for x into the formula for TU:
14(3) - 15 = x
42 - 15 = x
x = 27
TU = 27 units

The cost of the one canoe is $25.
According to the statement
We have to find that the cost of the one canoe.
So, For this purpose, we know that the
The cost function will be accustomed find the common cost, which is that the average amount of cash it costs to provide a unit.
From the given information:
The girls group rented 2 canoes and three inner tubes for a complete cost of $80. The boys group rented 1 canoe and seven inner tubes for a complete cost of $95.
Then
Let c is that the cost of renting a canoe and t is that the cost of renting inner tubes.
For the ladies,
2c + 3t = 80
For the boys,
c + 7t = 95
Solving the system of equations, multiply the second equation by 2 and subtract them.
2c + 3t = 80
2c + 14t = 190
11t = 110
t = 10
Now,
Substitute t to either equations,
c = 95 - 7t
c = 95 - 7(10)

What are the angle measures of the triangle?
Answer: 30, 60, 90 triangle ==> Option 3
Step-by-step explanation:
Lets say Angle A is the angle opposing the line of a triangle that has the length of 6. Lets say Angle B is the angle opposing the line of the same triangle that has the length of [tex]6\sqrt{3}[/tex].
sin A=6/12=1/2
sin A=30 degrees.
sin B=[tex]\frac{6\sqrt{3}}{12}[/tex]=[tex]\frac{\sqrt{3}}{2}[/tex]
sin B=60 degrees.

Considering the given area of the square, it is found that it's side length is an irrational number.
What is the missing information?This problem is incomplete, but researching it on a search engine, it asks if the side length of the square of area 89 cm² is rational or irrational.
What is the formula for the area of a square?
The area of an square of side length s is given by s squared, as follows:
A = s².
In this problem, the area is of 89 cm², hence:
s² = 89.
s = sqrt(89).
The square root of 89 is a non-exact root, hence it cannot be represented by fraction and is an irrational number.

Answer: x = 88 degrees
Step-by-step explanation:
The angles of a triangle add up to 180 degrees.
So

48 + 2x - 44 = 180
2x + 4 = 180
2x = 176
x = 88
Angle B = 88 degrees

To compare fractions you need to bring them to the same format.
1) Convert 3/5 to decimal:
3/5 = 30/50 = 60/100 = 0.60Compare:
0.60 < 0.85 as 60 < 852) Convert 0.85 to fraction:
0.85 = 85/100 = 17/20Bring 3/5 to the same denominator:

A student states that a triangle can be formed with side lengths 3 in, 5 in, and 9 in. is the student correct? why, or why not? yes, because 3 5 < 9 yes, because 3 9 > 5 no, because 3 9 > 5 no, because 3 5 < 9
A student is not correct when he stated that a triangle can be formed with side lengths 3 in, 5 in, and 9 in because 3 + 5 < 9.
A triangle is a polygon with three sides and three vertices.
To know if a set of numbers is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.
let a = 3, b = 5, and c = 9
a + b > c : 3 + 5 > 9 8 > 9 False
a + c > b : 3 + 9 > 5 12 > 5 True
b + c > a : 5 + 9 > 3 14 > 3 True
If at least one of these statements does not hold true, the measurements can't be the sides of a triangle.

Create a data set of 9 numbers that has a mean of 10 and a maximum of 15
Other answers are possible.
=========================================================
Explanation:
Let's say 10 is the median, and we'll have four values above it and four below. This gives 4+1+4 = 9 total items. One such example could be {6,7,8,9,10,11,12,13,14}. This is the set of whole numbers from 6 to 14 inclusive.
Due to the symmetry of that list, the mean = median = 10
The only problem is the max is 14, when we want it to be 15. We can fix this by adding 1 to each of the upper four values {11,12,13,14} to get {12,13,14,15}.
To balance things out, subtract 1 from each of the lower four values. So we go from {6,7,8,9} to {5,6,7,8}. This balancing is to keep the mean the same at 10.
Therefore, the set {6,7,8,9,10,11,12,13,14} becomes {5,6,7,8,10,12,13,14,15} which is one possible answer.
There are infinitely many other possible answers. The data set does not have to be symmetric like this.
