The area of the sector which is the white triangle adding the shaded region is 68.9/360*π*9.28^2=51.78005(rounding to 5th digit after decimal point for accuracy before we do final round for answer)
The area of the white triangle in the sector has area 1/2*9.28^2*sin(68.9)= 40.17223(rounding to 5 digits again for some accuracy.
Now we take out the white triangle from the sector.
51.78005-40.17223=11.60782
rounding to the nearest tenth we get 11.6 cm^2
Problem done!
Hope this helped and if you have any questions about my explanation just ask in the comment and I will answer.

Mr. Tyssee got a haircut, which cost $35. He gave the
stylist a 15% tip. How much will he pay for the haricut
including tip?
Answer:
$40.25
Step-by-step explanation:
15% = 0.15, so multiply 35 * 0.15 = 5.25 to get the tip.
Since the answer is asking for both the tip and the cost, add 35 + 5.25, which gives the answer $40.25
Here are some values of sequence Q. Write a recursive definition for the sequence.
n Q(n)
1 3
3 8
7 18
Answer: Q(n) = Q(n - 1) + 2.5
Step-by-step explanation:
We have 3 values of the sequence Q(n)
These values are:
Q(1) = 3
Q(3) = 8
Q(7) = 18
I would think that this is a geometric sequence.
Remember that the equation for the n-th term of a geometric sequence is:
A(n) = A(1)*r^(n-1)
where r is a constant, and A(1) is the first term of the sequence.
If we rewrite the terms that we know of Q(n) in this way we get:
Q(3) = Q(1)*r^(3 - 1) = 3*r^2 = 8
Q(7) = Q(1)*r^(7 - 1) = 3*r^6 = 18
Then we have two equations:
3*r^2 = 8
3*r^6 = 18
We should see if r is the same for both equations:
in the first one we get:
r^2 = 8/3
r = (8/3)^(1/2) = 1.63
and in the other equation we get:
r^6 = 18/3
r = (18/3)^(1/6) = 1.34
Then this is not a geometric sequence.
Now let's see if this is an arithmetic sequence.
The n-th term of an arithmetic sequence is written as:
A(n) = A(1) + (n - 1)*d
where d is a constant.
If we write the terms of Q(n) that we know in this way we get:
Q(3) = Q(1) + (3 - 1)*d = 3 + 2*d = 8
Q(7) = Q(1) + (7 - 1)*d = 3 + 6*d = 18
We need to see if d is the same value for both equations.
in the first one we get:
3 + 2*d = 8
2*d = 8 - 3 = 5
d = 5/2 = 2.5
In the second equation we get:
3 + 6*d = 18
6*d = 18 - 3 = 15
d = 15/6 = 2.5
d is the same for both terms, then this is an arithmetic sequence.
An arithmetic sequence is a sequence where the difference between any two consecutive terms is always the same value (d)
Then the recursive relation is written as:
A(n) = A(n - 1) + d
Then the recursive relation for Q is:
Q(n) = Q(n - 1) + 2.5

What is the value of z?
Answer:23
Step-by-step explanation:
Answer:
z = 23
Step-by-step explanation:
The angles in a triangle add up to 180°.
So, 62° + 95° + z = 180°.
Subtract 62 and 95 on both sides.
62 + 95 + z - 62 - 95 = 180 - 62 - 95
z = 23
Hope this helps! Feel free to ask any questions.

Answer:
94
Step-by-step explanation:
the sum of the angles in a triangle add up to equal 180
180-73-13=94
Answer: X = 89°
Step-by-step explanation:
At first glance I could tell this was an isosceles triangle, the angles of an isosceles triangle add up to 180°. So just add 73° + 13° = 91° so then you subtract 91° from 180° and you get 89°.

Which graph best represents the student's walk?
Answer:
A
Step-by-step explanation:
I finished the question and got it right
Graph is a way to represent a lot of data in a visual formal. The graph that best represents the student's walk is graph A.
What is a graph?A graph is a way to represent a lot of data in such a visual formal that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.
As we can see that the y-axis of the graph represents the distance traveled by the student while, the time taken by the student to cover the distance is given on the x-axis.
We know that the rate of 1.5 meters per second, means that the student will cover the 1.5 meters in 1 second, therefore, the line will be a slope that will represent the walk of the student. At time t=4 seconds, a student stopped for 4 seconds therefore, the time will increase but the distance will be constant for the student, therefore, the situation will be represented by a horizontal line.
Hence, the graph that best represents the student's walk is graph A.

How do you simplify 4ab + 13bc
Answer:
you cant
Step-by-step explanation:
its already simplified from the way its written
b(4a + 13c) is the simplified form of the expression 4ab + 13bc
To simplify the expression 4ab + 13bc, we can factor out the common term "b" from both terms:
4ab + 13bc = b(4a + 13c)
By factoring out the common term "b", we obtain the simplified form b(4a + 13c).
This represents the original expression in a more concise and factored form.
Hence, the simplified form of the expression 4ab + 13bc is b(4a + 13c) by taking the common term b
