First of all, 100cm makes 1m. So compare the statements
100cm=1m
2.5cm=Y
I represented the unknown with Y. Cross and multiply. 2.5 will multiply 1 to give 2.5 and Y will multiply 100 to give 100Y. That will be;
100Y=2.5
Divide both sides by 100
Y=2.5/100
But remember; 100cm is 1 meter. So that will be the same as;
Y=2.5cm/1m
which is C
Hope that helped. Have a nice day
Answer:
Step-by-step explanation:
Angular speed is given by 
, where 
is angle change in radians and 
is elapsed time.
Since the baseball makes one fourth (one quarter) of a rotation in 1.35 seconds, it will take the baseball 
seconds to complete on rotation.
One rotation is 360 degrees or 
radians. Therefore, the angular speed of the baseball is:
50 Because if you multiply 10 5 times it equals 100 percent.
Answer:
Total Area = 532 m²
Step-by-step explanation:
Triangle = ½bh.
Rectangle = lw.
Total Area = sum of individual areas =
(8 m × 16 m) / 2 + (16 m × 18 m) / 2
+ (18 m × 18 m) =
(64 m²) + (144 m²) + (324 m²) =
532 m²
The last one since the first one is up 13 and the last one is down 10
