Well 25% is the same as .25 or 1/4. So first you need to add X and Y so X+Y and since it is both you choose D
Answer:
Option 4 - 
Step-by-step explanation:
Given : In a circle with a radius of 6 ft, an arc is intercepted by a central angle of 3π/2 radians.
To find : What is the length of the arc?
Solution :
Length of an arc is given by:
where r is the radius of the circle, r= 6 ft.
and 
is the angle in radian, 
Substitute the value given in the formula,
Therefore, Option 4 is correct.
The arc of length is
The time for the job for which the two company are the same is 16
<h3>How to form the equation and find the cost?</h3>
A yard cleanup service charges a $345 fee plus $16.25 per hour. Therefore,
using linear equation,
y = mx + c
where
Therefore,
y = 345 + 16.25x
Another cleanup service charges a $213 fee plus $24.50 per hour. Therefore,
y = 213 + 24.50x
Hence, the time when both cost are the same is as follows;
213 + 24.50x = 345 + 16.25x
213 - 345 = 16.25x - 24.50x
-132 = -8.25x
x = 132 / 8.25
x = 16

Answer:
Kayla is correct; the center is a fixed point in the middle of the sphere.
Step-by-step explanation:
Kayla is correct. Raymond is wrong because a point cannot be a radius: a radius is a line segment from the center to the surface.
The center is the fixed point in the middle of the sphere.
