Step-by-step explanation:
1) As U is the mid point of TV ,it divides the whole line in two equal parts:
TV=TU+UV
TU=UV
Subtitute values:
5x+6=23+23
5x+6=46
5x=46-6
5x=40
x=40/5
x=8
2) Q is mid point of PR so PQ=QR
PR=PQ+QR
15x-29=6x-1+6x-1
15x-29=12x-2
15x-12x=29-2
3x=27
x=27/3
x=9

Answer:
Step-by-step explanation:
Diameter:
from this information we can find the radius of the golf ball:
A golf ball is shaped like a sphere, and the formula for finding the volume of a sphere is:
where r is the radius and is a constant:
we substitute the values of pi and the radius to find the volume:
the closest to the volume of a golf ball:
Answer:
45 degrees
Step-by-step explanation:
The square root of 12.5 is 3.53
Add 4 to the second equation to get
.. 3b = 6
Substitute this into the first equation to get
.. 2a +6 = 12
.. 2a = 6 . . . . . . . subtract 6
.. a = 3 . . . . . . . . divide by 2
The value of a is 3.
