The value of x in the shape is 111
How to determine the value of x?The shape is a heptagon
This is so because the shape has 7 sides
i.e. n = 7
The sum of angles in the shape is
Sum = 180(n - 2)
So, we have
Sum = 180(7 - 2)
Evaluate
Sum = 900
Also, the sum of angles in the shape is
Sum = x + 120 + 158 + 126 + 125 + 121 + 139
This gives
Sum = x + 789
So, we have
x + 789 = 900
Evaluate the like terms
x = 111
Hence, the value of x in the shape is 111

Answer:
x = 0.5
Step-by-step explanation:
Given
- 8.25x + 12 - 1.75x = 10.5x + 1.75 , that is
- 10x + 12 = 10.5x + 1.75 ( subtract 10.5x from both sides )
- 20.5x + 12 = 1.75 ( subtract 12 from both sides )
- 20.5x = - 10.25 ( divide both sides by - 20.5 )
x = 0.5
Describe the graph of y > mx, where m > 0?
Answers
Answer:
The graph of y > mx, where m > 0, consists of a dashed line and a shaded half-plane. The line has a positive slope and passes through the origin. The shadow of the half plane is above the line. m<0 means slope is negative
b>0 means the line will intersect the y axis above 0. Since the slope is positive, the graph is increasing. So like stated above The boundary line is dashed, and everything above it is shaded.

Use the definition of continuity to determine whether the function f(x) graphed
below is continuous at x = 0.
Answers
The function graphed below is not continuous.
On the graph at x = 0, the function is not continuous. There is a jump on the graph at x = 0.
A function is said to be continuous if the graph of the function has no break, hole or asymptotes.
In this graph it is clear that the graph is not continuous because the function approaches -4 until when x = 0 and then after x = 0, function takes the values from 1.
This causes a jump on the graph of the function which gives a discontinuity at x = 0.

c) -5/6
d) 4/-6
From the format of -4/9 and -7/8 you can deduct that it is either A or C, -5/-6 (a) will be a positive decimal so therefore the answer is C because it is the only fraction in the correct format that has an answer on between the two in the problem.

Xavier can swim at a constant speed of 5/3 meters/second. He is trying to qualify for the N ational Swim Meet. To qualify, he must complete a 100-meter race in 55 seconds. Will Xavier be able to qualify? Why or why not?
Answers
Answer:
Xavier will not be able to qualify because the speed required for him to qualify is greater than the speed at which he runs
Step-by-step explanation:
Here, we want to know if Xavier will be able to qualify or not
His constant speed is 5/3 m/s
Now to win , he needs a speed of 100 m/55 sec = 20/11 m/s
So now, we need to know the bigger fraction between the two
Mathematically, that will be
5/3 - 20/11 = (55-60)/11 = -5/11
As we can see, the required speed is greater than what he can run
So this means that he will not be able to qualify

Answer:
122.5 People
Step-by-step explanation:
4500-90 = 4410
4410 divided by 36 equals 122.5
==========================================================
Explanation:
n = number of people invited
n+2 = total number of people after adding Oscar and Julie
36(n+2) = total cost before the $90 fee
36(n+2)+90 = total cost after the $90 fee
Set that equal to the budget of 4500 and isolate n
36(n+2)+90 = 4500
36n+72+90 = 4500
36n+162 = 4500
36n = 4500-162
36n = 4338
n = 120.5
n = 120
We round down so that we don't go over budget
Oscar and Julie can invite 120 people.
-----------
Check:
If n = 120 then 36(n+2)+90 = 36(120+2)+90 = 4482 which is under budget
If n = 121 then 36(n+2)+90 = 36(121+2)+90 = 4518 which is over budget
This confirms that 120 is the answer.

What is the definition of a sample proportion?The sample percentage (p) represents the proportion of people in a sample who have a particular attribute or trait. Divide the number of persons (or objects) who have the characteristic of interest by the total number of people (or items) in the sample to get the sample proportion.
Given there are 36 successful outcomes in a sample with a size of 80. Therefore, the sample proportion is,
Sample proportion = 36/80 = 0.45
