Answer:
Step-by-step explanation
You must find the common denominator for all of them.
A is correct. 13 x 2 is 26 and 14 x 2 is 28. Therefore, 13/14 is greater than 25/28.
B is not correct. 4 x 5 is 20 and 9 x 5 is 45. 4/9 is actually less than 21/45.
C is not correct. 5 x 2 is 10 and 6 x 2 is 12. 5/6 is actually less than 11/12.
D is not correct. 4 x 5 is 20 and 5 x 5 is 25. 4/5 is actually less than 8/25.
Here you go, hope it's right. The top one is the equation and the bottom one is the work to get the answer.
There are 4.53592 kilograms in 10 lbs.
<span>F=(m*V²)/r
</span>F=centripetal force
m=mass of the object going in a circle
v=object´s velocity
r=radius of circle of curve
m=2000 Kg
v=25 m/s
r=80 m
F=[2000 Kg*(25 m/s)²] / 80 m=15625 N
<span>answer is 15625 N </span>
