Answer:
The arc length XY is equal to
or 
Step-by-step explanation:
The picture of the question in the attached figure
step 1
Find the circumference of the circle H
The circumference is given by the formula

we have

substitute

step 2
we know that
The circumference of a circle subtends a central angle of 360 degrees
so
using proportion
Find out the length of the arc xy if the central angle is equal to 100 degrees
Remember that
---> by central angle

Simplify
----> exact value
To find out the approximate value
assume

substitute
----> approximate value
therefore
The arc length XY is equal to
or 
Answer:
Car B.
Step-by-step explanation:
Car A : 12,380 = 12,400 --> diff : 20
Car B : 16,760 = 16,800 --> diff : 40
Car C : 14,580 = 14,600 --> diff : 20
Answer:
The total yearly cost is $300 at each gym for 50 visits.
Step-by-step explanation:
Healthy Gym: 6n = t
Fitness Gym: 50 + 5n = t
When n = 50 visits, then...
Healthy Gym: 6(50) = $300
Fitness Gym: 50 + 5(50) = $300
The first equation is a constant. There is no input necessary, and the output remains 5.
The second equation is also a constant. The output is 4.
In the third equation, y depends on what value of x you use. x is the input and y is the output.
In the fourth equation, x depends on what value of y you use. The way it is written, y is the input and x is the output.
In the last equation, either x or y could be the input. The other variable would change depending on which variable you replace with a number.
X=alice
b=barry
c=charlene
x=15 more than b
x=15+b
c=2 times of b
c=2b
all together
x+c+b
15+b+2b+b
15+4b
they have 15+4b or 15+4 times of barry
if we want in terms of x
x=15+b
x-15=b
15+4(b)
15+4(x-15)
15+4x-60
4x-45
they have 4x-45 together
