A circle has a circumference of 6. It has an arc of length 1.
What is the central angle of the arc, in degrees?
Answers
Answer:
60 degrees
Step-by-step explanation:
s = r (theta)
(theta) = s/r
= 1 / (3/π) = π/3
as a degree π/3 x 180/π = 60
60 degrees
*Circumference = 2πr
6 = 2πr

A.
(75 + 25)h
B.
75 + 25h
C.
75h + 25
D.
75 + 25 + h
Answers
Answer:B i think if wrong im so sorry
Step-by-step explanation:
Answer:
B 75+25h
Step-by-step explanation:
$75 is the first charge for the service and is constant. $25(per hour) is not constant and changes as the time (hours) changes. That's why it has a h next to it, the h is the variable to hold the place for the hours that would be multiplied in the problem.

What is an equation?An equation is an expression showing the relationship between numbers and variables.
Weight is the quantity of matter stored in an object. The SI unit of weight is the kilograms.
1 inch = 0.0254 meter
1 m = 1000 mm
Given the nail is 1 inch, hence:
1 inch = 0.0254 m
0.0254 m = 0.0254 m * 1000 mm/m = 25.4 mm
The length of the nail is 25.4 mm

Josh is going to the store with $60 to buy candy. bags of candy corn cost $3 & bags of chocolate cost $5 he needs to buy at least 20 bags of candy.
What do I put for the blank space? 3x+5y_60
Answers
Answer:
3a+5b
Step-by-step explanation:
Variable 1: a = candy corn
Variable 2: b = chocolate
Inequality 1: 60 ≥ 3a + 5b
Inequality 2: 20 ≤ 3a + 5b
The inequalities are as such because Josh needs to spend no greater than $60. He must also buy at least 20 bags of candy. The candy corn costs $3, while the chocolate costs $5. An expression for the total cost of the candy would be 3a + 5b.

what is 2.1 times 3.2 find the missing partial products HELP.
Answers
Given:
The area model for [tex]2.1\times 3.2[/tex].
To find:
The value of [tex]2.1\times 3.2[/tex] and the missing values in the area model.
Solution:
2.1 can be written as 2 and 0.1 on the left side of the area model.
3.2 can be written as 3 and 0.2 on the top of area model.
Area of the four parts of the area model are:
[tex]2\times 3=6[/tex]
[tex]2\times 0.2=0.4[/tex]
[tex]0.1\times 3=0.3[/tex]
[tex]0.1\times 0.2=0.02[/tex]
The complete area model is shown below.
After adding all areas of the area model, we get
[tex]6+0.4+0.3+0.02=6.72[/tex]
Therefore, the value of [tex]2.1\times 3.2[/tex] is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.

two angles are supplementary. the bigger angle is three times as large as the smaller angle.find the measurement of the angles
Answers
Answer:
The bigger angle is 135, and the smaller angle is 45.
Step-by-step explanation:
First, you have to know that supplementary angles add up to 180°.
We have no equations for the angles, so I will use the variable x for the value of the smaller x.
The reason for this: the problem gave the value of the bigger angle, but relative to the smaller angle. Therefore, it would be safe to assume the use of a variable for the smaller angle.
Since the bigger angle is 3 times as large as the smaller, we can say that the bigger angle is 3x, or 3 times x.
Now, we can put this in an equation: 3x+x=180. Like I said before, both of the angles add up to 180 degrees.
To solve the equation:
1. Combine like terms
4x=180
2. Divide both sides by 4
x=45
Now that we have the value of x, we can plug that in to 3x and x to find the angles.
3*45=135, which is the bigger angle
45, which is the smaller angle.

The art club is designing a rectangular mural for the school hallway. Three corners are located at (-1, -1), (-1, 1), and (4, 1) on teh coordinate plane. What would be the forth vertex on the coordinate plane below?
Answers
Answer:
The fourth vertex must be located at [tex]Z(x,y) = (4, -1)[/tex]. The graph of the figure is included below.
Step-by-step explanation:
Let be [tex]X(x,y)[/tex], [tex]Y(x,y)[/tex], [tex]Z(x,y)[/tex] and [tex]W(x,y)[/tex] so that a rectangle is formed. Hence, we must satisfy the following conditions:
[tex]X(x,y) = (a, c)[/tex] (1)
[tex]Y(x,y) = (a, d)[/tex] (2)
[tex]Z(x,y) = (b, c)[/tex] (3)
[tex]W(x,y) = (b, d)[/tex] (4)
[tex]a < b[/tex] (5)
[tex]c < d[/tex] (6)
If we know that [tex]a = -1[/tex], [tex]b = 4[/tex], [tex]c = -1[/tex], [tex]d = 1[/tex], then we have the following points:
[tex]X(x,y) = (-1, -1)[/tex]
[tex]Y(x,y) = (-1, 1)[/tex]
[tex]Z(x,y) = (4, -1)[/tex]
[tex]W(x,y) = (4,1)[/tex]
Then, the fourth vertex must be located at [tex]Z(x,y) = (4, -1)[/tex].
