Since all circles are similar, a proportion can be set up using the circumference and diameter of each circle. Substitute the values d1 = 1, C1 = π, and d2 = 2r into the proportion.
StartFraction C 1 Over d 1 EndFraction = StartFraction C 2 Over d 2 EndFraction
Which shows how to correctly solve for C2, the circumference of any circle with radius r?
A. Because StartFraction pi Over 1 EndFraction = StartFraction C 2 Over 2 r EndFraction , C 2 = 2 r pi
B. Because StartFraction 1 Over pi EndFraction = StartFraction C 2 Over 2 r EndFraction ,
2 = StartFraction 2 r Over pi EndFraction
C. Because StartFraction pi Over 2 r EndFraction = StartFraction C 2 Over 1 EndFraction , C 2 = StartFraction pi Over 2 r EndFraction
D. Because StartFraction pi Over 1 EndFraction = StartFraction C 2 Over 4 r EndFraction , C 2 = 4 r pi

What is the slope of the line between the points (-2,1)and(1,3)?
Answer:
2/3
Step-by-step explanation:
The slope is found by
m = (y2-y1)/(x2-x1)
= (3-1)(1--2)
= (3-1)/(1+2)
=2/3
We can use the points (-2, 1) and (1, 3) to solve.
Slope formula: y2-y1/x2-x1
= 3-1/1-(-2)
= 2/3

Answer:
Step-by-step explanation:
hello :
given the line : 5x – 2y = -6
the answer is : 2x + 5y = -10 because :
1) this line passes through then point (5 ,-4) : 2(5)+5(-4)=-10....right
2) the slope of the given line is: 5/2 because 5x-2y=-6 equivalent to ;
2y =5x+6 so : y = (5/2)x+3
On the other hand : 2x + 5y = -10 equivalent to : 5y =-2x-10
y = (-2/5)-2 when the slope is : -2/5
the condition for the perpendicularity is : product two slope is : - 1
(5/2)(-2/5) =-1
A restaurant uses 4.375 pounds of cheese for every pizzas. At this rate, how many pounds of cheese are used per pizza?
Final answer:
To determine the amount of cheese used per pizza, divide the total amount of cheese (4.375 pounds) by the number of pizzas (50), which equals 0.0875 pounds of cheese per pizza.
Explanation:
To find out how many pounds of cheese are used per pizza, we calculate the cheese usage rate by dividing the total pounds of cheese by the number of pizzas. The given information tells us that 4.375 pounds of cheese are used for every 50 pizzas. To find the amount of cheese used per pizza, we divide 4.375 pounds by 50.
4.375 pounds ÷ 50 pizzas = 0.0875 pounds per pizza
Thus, the restaurant uses 0.0875 pounds of cheese for each pizza made.
Using the Addition Method, solve for y in the following system of linear equations.
4x-2y=6
2x+y=7
Answer:
x = 3.33
y = 0.33
Step-by-step explanation:
to evaluate for y in this system of linear equation we would say that let
4x-2y=6 ........................................................... equation 1
2x+y=7 ..............................................................equation 2
from equation 2
2x+y=7 ..............................................................equation 2
y = 7 - 2x........................................... equation 3
substitute for y in equation 1
4x-2y=6 ........................................................... equation 1
4x -2( 7 - 2x) = 6
4x - 14 + 2x = 6
6x = 6 +14
6x = 20
divide both sides by 6
6x/6 = 20/6
x = 3.33
put x into equation 3
y = 7 - 2x........................................... equation 3
y = 7 -2( 3.33)
y = 7 -6.667
y = 0.33
Final answer:
To solve for y using the Addition Method, first manipulate the equations to have opposite coefficients for y, add them to find x, and then substitute x back into one of the original equations to solve for y. The solution is x = 2.5 and y = 2.
Explanation:
The student is asking how to solve for y in a system of linear equations using the Addition Method. The given system of equations is:
4x - 2y = 6
2x + y = 7
To use the Addition Method, we aim to eliminate one variable by adding the equations. First, we manipulate the equations to have opposite coefficients for the y variable. Multiply the second equation by 2:
(2x + y) × 2 → 4x + 2y = 14
Now we have:
4x - 2y = 6 (Equation A)
4x + 2y = 14 (Equation B)
Add Equation A and Equation B:
4x - 2y + 4x + 2y = 6 + 14
8x = 20
x = 20 / 8
x = 2.5
Substitute x back into the second original equation to solve for y:
2(2.5) + y = 7
5 + y = 7
y = 7 - 5
y = 2
Hence, the solution to the system of equations is x = 2.5 and y = 2.
Which angle is adjacent to Angle D F E?
Line A F E is horizontal. Lines B, C, and D come out of point F.
Angle A F B
Angle A F C
Angle B F D
Angle B F C
Answer:
I think its <afb
Step-by-step explanation:
The required, adjacent angle to DFE is angle BFC. Option D is correct.
What is the angle?Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Angle BFC is next to angle DFE, and they share a common side, which is line segment EF. Therefore, we can stretch this statement as follows:
"When looking at the angle DFE and moving clockwise around the vertex F, the next angle encountered is angle BFC, which is adjacent to angle DFE and shares the side EF with it."
This restatement clarifies the location and relationship of angle BFC with respect to angle DFE.
Thus, the required, adjacent angle DFE is angle BFC. Option D is correct.

What is the value of the expression when x = -2?
When x is substituted with -2 in the given expression, the value of the expression is 1.
Explanation:Given the expression and the value of x, we can substitute x with -2 and evaluate the expression. For example, if the expression is x² + 2x - 3 and you want to find the value when x = -2, then you'd substitute x = -2 into the expression giving (-2)² + 2*(-2) - 3 = 4 - 4 - 3 = -3. Substituting values in, simplifying, and solving is the general process to follow when coming across this kind of problem in quadratic equations or other areas of Algebra.
Let's say the expression is 2x + 5. Substituting x with -2, we get:
2*(-2) + 5 = -4 + 5 = 1
Therefore, the value of the expression when x = -2 is 1.
