The angle that an arc makes at the center of the circle of which it is a part. One measure of an arc is the angle formed by the arc at the center of the circle that it is a part of. ... (The other is the length of the arc - see Length of an Arc.)
Answer:
135
Step-by-step explanation:
the circumfrence of a whole circle is 2pir, so it's 16 pi, that segment is 6
16pi/6pi = 360/x
simplify to: 8/3 = 360/x
8x = 1080
x=135
Decide whether the relation is a function, and give the domain and range.

5x = y +6
5x + 2y = 3
I forgot how to solve it I need help
Answer:
Y=3
X=9/5
Step-by-step explanation:
(1) 5x=y+6
(2) 5x+2y =3
Replace (1) to (2) => (y+6)+2y=3 => y=3
Replace y=3 to (2) => 5x = 3+6 => 5x=9 => x=9/5
Consider the following sequence and type the next number in the sequence.
55, 48, 41,34
The required number next number in the sequence is 27.
Given that,
Sequence = 55, 48, 41,34, the number that comes next in the sequence is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
here,
Given sequence,
55, 48, 41, 34
The sequence has a common difference of 7,
When we subtract 7 from the number 34, the next number in the sequence can be calculated,
So.
next number = 34 - 7 = 27
Thus, the required number next in the sequence is 27.

Suppose y varies at a constant rate of change of 0.5 with respect to x (so that Δ y = 0.5 ⋅ Δ x ), and y = 1.5 when x = 3 .
Answer and explanation:
Given the above, we find y in terms x
change in y change in x = 0.5
The formula for a straight line is y= mx+b where m is slope of the line and b is the y intercept
We substitute given values above in the straight line equation:
y=mx+b
1.5= 0.5×3+b
1.5=1.5+b
b= 0
y in terms of x for the line is therefore given by the formula :
y=0.5x+0

What is the constant in this expression 4x+5y-3? (3 points) a 4x b y c 5 d 3
Answer:
-3 is a constant.
Step-by-step explanation:
The given equation is :
4x+5y-3 ...(1)
The general equation is :
ax+by+c ...(2)
c is a constant
If we compare equations (1) and (2), we find that.
c=-3
Hence, the constant in this expression is -3.

A water tank is contaminated with a colony of 20 000 e.Coli bacteria. After 3 days the bacteria has grown to 28 284 e. Coli. What is the doubling time of the bacteria using an equation
Answer:
6
Step-by-step explanation:
The formula for doubling time is given as:
P(t) = Po(2)^t/k
Where:
P(t) = Population after time t = 28,284
Po = Initial Population = 20,000
t = time = 3 days
k = doubling time = ?
28,284 = 20,000 × (2)^3/k
Divide both sides by 20,000
28,284/20,000 = 20,000/20,000 × (2)^3/k
1.4142 = (2)^3/k
2^1/2 = (2)^3/k
Divide both sides by 2
1/2 = 3/k
Cross Multiply
k × 1 = 2 × 3
k = 6
Therefore, the doubling time(k) of the bacteria is 6
At dinner, the meal cost $24 and the sales tax was $1.32. What was the tax rate? Write your answer as the percent with no % sign
Answer:
5.5
Step-by-step explanation:
Sales tax = tax rate × Cost of meal
Sales tax = $1.32
Tax rate = x%
Cost of meal = $24
Sales tax = tax rate × Cost of meal
1.32 = x% × 24
1.32 = x/100 × 24
1.32 = 24x/100
1.32 * 100 = 24x
132 = 24x
x = 132/24
x = 5.5%
= 5.5

9x - 6y = -21 and 6x - 12y = -6 How would I solve by substitution?
Answer:
(-3,-1)
Step-by-step explanation:
6x-12y=-6
6x=12y-6
x=2y-1
9(2y-1)-6y= -21
18y-9-6y=-21
12y= -12
y=-1
6x-12(-1)=-6
6x+12= -6
6x=-18
x=-3
Answer:
x = -3 ; y = -1
Step-by-step explanation:
Let 9x - 6y = -21 be eqn.1 & let 6x - 12y = -6 be eqn.2 .
Lets find the value of x from eqn.1
[tex]9x - 6y= -21[/tex]
[tex]=> 3(3x - 2y) = -21[/tex]
[tex]=> 3x - 2y = \frac{-21}{3} = -7[/tex]
[tex]=> x = \frac{2y - 7}{3}[/tex]
Now , lets put the value of x (which we got from eqn.1) in eqn.2 :-
[tex]6x - 12y = -6[/tex]
[tex]=> 6(x - 2y) = -6[/tex]
[tex]=> x - 2y = \frac{-6}{6} = -1[/tex]
(Putting x here)
[tex]=> \frac{2y - 7}{3} - 2y = -1[/tex]
[tex]=> \frac{2y - 7 - 6x}{3} = - 1[/tex]
[tex]=> -4 y - 7 = -1 \times 3 = -3[/tex]
[tex]=> -4y = 7 - 3 = 4[/tex]
[tex]=> y = \frac{-4}{4} = -1[/tex]
Now , lets find the value of x.
[tex]x = \frac{2y - 7}{3}[/tex]
Putting y = -0.5 gives ,
[tex]x = \frac{[2 \times (-1)] - 7}{3}[/tex]
[tex]=> x = \frac{-2 - 7}{3} = \frac{-9}{3} = -3[/tex]
Part A
What is the y-intercept and what does it represent?
Part B
What is the x-intercept and what does it represent?
Answer:
a) The y-intercept is 160. It represents the initial distance Jayden was from his home.
b) The x-intercept is 4. It represents the amount of time taken for Jayden to reach his home.
Step-by-step explanation:
The y-intercept can be found by looking at the value of y when x=0. When x=0, y= 160. Since the x-axis is the amount of time in hours, x=0 would mean the initial time. The x-axis is the number of miles from Jayden's home thus, Jayden was 160 miles away from his home when x=0 hours.
The x-intercept can be found by looking at the x value when y=0. When y=0, x=4. This means that it took Jayden 4 hours to reach home or 4 hours to travel 160miles to his house.

An extremely handsome math teacher was on a farm and he counted 32 animals; all pigs and chickens. Then he counted the number of feet. The total was 88. Find the number of pigs and the number of chickens. (Hint: You need to take the number of legs each animal has into consideration.)
15 pigs and 17 chickens
12 pigs and 20 chickens
20 pigs and 12 chickens
22 pigs and 10 chickens
Answer:
12 pigs and 20 chickens
Step-by-step explanation:
Chicken = 2 legs
Pig = 4 legs
(15 * 4) + (17 * 2) = 88 NO
(12 * 4) + (20 * 2) = 88 Yes, and 12 + 20 = 32
