X = 3 so 22 needstobe20characterslong
Answer:
A man drove x miles per hour for 3 hours and (2x-60) miles per hour for the next 4.75 hours.Express the total distance traveled in terms of x.
Total distance covered by the man in terms of 'x' = (12.5x-285)miles
Step-by-step explanation:
Given:
Speed of a man = 'x' miles/hour
Time taken =
hour
So, distance = product of speed and time.
Distance covered in term of 'x' 
Now,
Speed =
miles/hour
Time taken=
hours
Distance
= 
= 
=
miles
Total distance covered by the man = Summation of
and 
= 
=
miles
So the total distance covered by the man in terms of 'x' = (12.5x-285) miles.

The volume of the spherical piece is 288.55 cm³.
Solution:
Diameter of the sphere = 8.2 cm
Radius of the sphere = 8.2 ÷ 2 = 4.1 cm
The value of π = 3.14
Volume of the sphere 


= 288.55 cm³
The volume of the spherical piece is 288.55 cm³.
