Answer:
Step-by-step explanation:
Circumference of a circle: C = 2*π*r
22/7 or π = 3.14
r (radius) = d/2
5. d/2 = 2
r = 10/2 = 5 cm.
C = 2*π*r
C = 2*3.14*5
C = 10*3.14
C = 31.4 cm.
6. r = 90 in.
C = 2*π*r
C = 2*3.14*90
C = 180*3.14
C = 565.2 in
7. r = 16 yd.
C = 2*π*r
C = 2*3.14*16
C = 32*3.14
C = 100.48 in
8. r = 4 in.
C = 2*π*r
C = 2*3.14*4
C = 8*3.14
C = 25.12 in.
9. d/2 = 2
r = 22/2 = 11 cm.
C = 2*π*r
C = 2*3.14*11
C = 22*3.14
C = 69.08 cm.
10. d/2 = 2
r = 4/2 = 2 m.
C = 2*π*r
C = 2*3.14*2
C = 4*3.14
C = 12.56 m.
11. In short words, a radius is half of its diameter. So a circle with a diameter of 8 cm has a radius of 4 cm because r = d/2. 8/2 = 4 cm.
Hope this helps!
Answer:
1. C = 31.4 cm. 2. C = 565.2 in 3. C = 100.48 in 4. C = 25.12 in. 5. C = 69.08 cm. 6. C = 12.56 m.

Answers
Answer:
y=2x+7
Step-by-step explanation:
We can substitute values x and y in the equations to see if it works in the equations.
For example, the first equation is y=-2x+6. Using the point (-3, 1), we know that 1 is the y value and -3 is the x value. So, 1 = -2(-3)+6
We can rearrange this is to get 1=12. This is false, so this can't be the right answer.
y=2x-1
1=2*-3-1 so 1=-7 which is also false
y=2x+7
1=2*-3+7 so 1=1 which is true!
We can use any of the points given to check that this equation works.
Hope this helps!
Answer:
y = 2x + 7
Step-by-step explanation:
Slope intercept form: y = mx + b
You will need to find the slope and y-intercept
First, find the slope: = y2 - y1 / x2 - x1
Given points: (-3, 1) (-2, 3)
m = 3 − 1 / −2 − −3
m = 2 / 1
m = 2
Slope is 2, now find the y-intercept
y = 2x + b (Use point (-3, 1))
1 = 2(-3) + b
1 = -6 + b
b = 7
Equation: y = 2x + 7

Answer:
x = 10, m∠TRS = 60°
Step-by-step explanation:
It is given that the total measurement of m∠QRS = 122°. Set the equation. Note:
∠QRS = ∠QRT + ∠TRS
Plug in the corresponding terms with the corresponding angles:
122 = 7x - 8 + 6x
First, simplify by combining like terms:
122 = (7x + 6x) - 8
122 = 13x - 8
Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Divisions
Additions
Subtractions
~
First, add 8 to both sides of the equation:
122 = 13x - 8
122 (+8) = 13x - 8 (+8)
122 + 8 = 13x
130 = 13x
Next, divide 13 from both sides of the equation:
(130)/13 = (13x)/13
130/13 = x
x = 10
Next, plug in 10 for x for the measurement of m∠TRS
m∠TRS = 6x
m∠TRS = 6 (* 10)
m∠TRS = 60°
Answer: x = 10, m∠TRS = 60°

Tell wether the angles are adjacent or vertical. Then find the value of x.
Answers
Answer:
The angles are vertical
Step-by-step explanation:
x+42+2x+1=180
put the like terms together i.e 2x+x+42+1=180
you get: 3x+43=180
Take 43 to th other side of 180 i.e 3x=180-43 i.e (180-43=137)
You get 3x=137
Divide both sides by 3
you get x=45.666666666667(Round off to get 45.67)
Substitute the value of x to the angles
x+42(45.67+42=87.67)
2x+1(2(45.67)+1=92.34
Add 87.67+92.34=180
THis shows that the angles are vertical

A farm lets you pick 3 pints of raspberries for $12.00.
1. What is the cost per pint?
2. How many pints do you get per dollar?
3. At this rate, how many pints can you afford for $20.00?
4. At this rate, how much will 8 pints of raspberries cost?
Answers
Answer:
1. $4
2. 1/4 or .25 pints
3. 5 pints
4. $32
Step-by-step explanation:
1. $12/3= $4
2. 1/$4= 1/4 or .25 of a pint
3. $20/$4 = 5 pints
$. 8x$4 = $32
1: Each pint costs $4.00, since 12/3=4

Look at the graph of a line segment before and after a transformation occurred,
Which statement describes the transformation that could have been made to the line segment?
A. The line segment was dilated by a factor of 1/2
B. The line segment was rotated 180° about the origin
C. The line segment was reflected over the x-axis
D. The line segment was translated 6 units down and 1 unit left
Answers
It can't be A because the line does not change length. It's can't be B because if you imagine the movement of the line, when rotated the A and B points would switch side visually. It can't be D because the transformed line segment has not moved 1 unit left.

Answer:
14 , 15 , 16
Step-by-step explanation:
"Consecutive" by definition means, quote "in unbroken or logical sequence". This means that, in the case of three numbers, the least number will be denoted by the variable, x, while the following "consecutive" numbers would be 1 greater than the last, making the terms 'x + 1' & 'x + 2'.
Set the equation:
x + (x + 1) + (x + 2) = 45
First, combine like terms. Like terms are terms with the same amount of the same variables:
(x + x + x) + (1 + 2) = 45
3x + 3 = 45
Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and stands for:
Parenthesis , Exponents (& Roots), Multiplications, Divisions, Additions, Subtractions.
First, subtract:
3x + 3 (-3) = 45 (-3)
3x = 45 - 3
3x = 42
Next, divide 3 from both sides of the equation:
(3x)/3 = (42)/3
x = 42/3
x = 14
Next, find the next three terms:
x = 14
x + 1 = 15
x + 2 = 16
Check: 14 + 15 + 16 = 45 (True).
Therefore, the 3 numbers is 14, 15, 16.
