Answer:
C. 3.33 hours
Step-by-step explanation:
Use the algebra work equation:
= 
+ 
, where tb is the time to work together, t1 is the time it takes one person, and t2 is the time it takes the other person
Plug in the values we know:
= 
+ 
= 
+ 
= 
20 = 6tb
3.33 = tb
So, it would take them 3.33 hours when working together.
The length of the segment x is 16.2
Step-by-step explanation:
Here apply the Pythagorean relationship which states that the sum of squares of the sides is equal to the square of the hypotenuse.
Mathematically,
a²+b²=c²
where a=15, b=6, c=r
Hence;
15²+6²=c²
225+36=c²
√261=c
16.16
x⇒16.2
