Answer:
L = πr
Step-by-step explanation:
Formula for calculating the length of an arc is expressed as:
L = theta/360 × 2pir
The angle substended by the semi circle is 180°
Substitute the given values
L = 180/360×2πr
L = 1/2 × 2πr
L = πr
Hence the length of the arc of a semi circle in terms of pi is L = πr where:
r is the radius of the semi circle

Find the measure of arc CD in p
9514 1404 393
Answer:
57°
Step-by-step explanation:
TD is a diameter, so arc TCD is 180°. Then arc CD is ...
CD = arc TCD -arc TC
CD = 180° -123°
arc CD = 57°
Find the measure of arc CD in P.
___________________Solution :-Given Information :-Arc TC = 123°Arc TCD = 180° ( Reason :- Arc TCD is the diameter of circle )Arc BT = 90° To Find :-Measure of Arc CD Calculation :-Because Arc TC and Arc CD comprise the Arc TCD,
⇒ Arc TC + Arc CD = Arc TCD
Substituting the values given, We get,
⇒ 123° + Arc CD = 180° ( Reason :- Arc TCD is the diameter of circle )
Now, Transposing 123° to Right Hand Side, We get,
⇒ Arc CD = 180° - 123°
⇒ Arc CD = 57°
∴ Arc CD = 57°
____________________Final Answer :-Arc CD measures 57°

Answer:
8
Step-by-step explanation:
So, lets go over a few things:
First off, all triangles have a total angle of 180 degrees.
Secondly, we know that the first two angles are 57 and 51.
Thirdly, we know that the missing angle is 9x
To solve this, we must add together the known angles, subtract them fro 180, and divide that by 9. This will give us the missing x value.
So, add together the two angles we know:
57+51
=
108
So we know 108 degrees of our triangle. We must find whats left of the 180.
To do this, subtract 108 from 180:
180-108
=
72
So our remaining angle is 72 degrres.
But recall that x isnt the misisng angle, 9x is.
So, to get x on its own, we must divide both the missing angle and 9x by 9:
72=9x
--- ---
9 9
=
8=1x
So now we know that x equals 8.
I hope this helps! :)
Answer:
X = 8
Step-by-step explanation:
Okay so we know that there are a total of 180 degrees in every triangle. We need to create the equation to define the triangle's angles. 51 + 57 + 9x = 180. Then, we will solve for x.
180 = 51 + 57 + 9x we are going to simplify the equation by solving what we can
180 = 108 + 9x * Now we will isolate x
180 - 108 = 9x * Solve the left side of the equation
72 = 9x * Divide both sides by 9
8 = x
Find the missing values in the Table of Values. Write your numbers from top to bottom in the space below with a comma between each value.
PLEASE DON'T GIVE A LINK OR DELETE THE ANSWER BECAUSE THIS IS MY SECOND TIME POSTING THIS SO PLS PLS PLS GIVE A PROPER ANSWER TO ALL OF THE PICTURES.
Answer:
Alright, with this, its essentially asking for you to plug in X into each equation for the answer.
With the first box, it asks for y = 5 - x, given the x = -2.
y = 5-x
y=5-(-2)
y=5+2
y=7
With the second box down, it wants things a bit differently, it gives you the y value, and wants for you to find the x. Given this, this question can be done backwards for the x value.
y = 5-x
6 = 5-x
x+6= 5
x=-1
With the third one, its the same thing as with the first box.
y = 5-x
y = 5-0
y = 5
Same thing with the fourth one.
y = 5-1
y = 4

A factory makes rods by cutting plastic pipes that are 4 feet long into 7 equal-sized rods. How long is each rod? (enter your answer as a fraction or a mixed number)
What is the total length of 15 rods? (enter your answer as a fraction or a mixed number)
Answer:
4/7
Step-by-step-- It is given that we have cut the 4 ft long.
We have to make it into 7 times it's original piece.
To determine this Is the length of the new rods.
Let the length of each new rod be x.
We need 7 rods-
7x = 4 ft
1 = 4/7x
x = 4x/7x
So, x gets cancelled. Now, we get the answer as . 4/7
hope this helped..:))
Answer:
4/7
Step-by-step explanation:
A line passes through points (2,5) and (5, 14). What is the slope of this line?
We know that:
Slope of a line = change in y coordinate / change in x coordinate
We are given:
First point = (2,5)
Second point = (5, 14)
Calculating the change in y coordinate:
change in y (also represented by Δy) = second y - first y
Δy = 14 - 5
Δy = 9
Calculating the change in x coordinate:
Δx = second x - first x
Δx = 5 - 2
Δx = 3
Slope of the line:
Slope = (Δy) / (Δx)
Slope = 9 / 3 [replacing the values]
Slope = 3
