The answer is 12.5 meters per seconds
Answer:
x*(2/3)=y
y*1.5=x
Step-by-step explanation:
There is 2/3rds the amount of sodium in the new one, y. If you multiply the odl one, x, by 2/3, you'll have the amount in the new one. Because half of 2/3rds is 1/3, if you multiply the new one by 1.5, you'll end up with 3/3, or 1, which is the amount in the old one.
First subtract 5 from both sides:
5x/7 = 25
Now multiply both sides with 7:
5x = 175
Divide by 5:
x = 35

Answer: 29.7 degrees
Step-by-step explanation:
Good, I can see the diagram now!
First calculate circumference of the circle.
C=2πr
C=2π(27)
C=54π in ==> 360 degrees
54π/14=12.11757
360/12.11757=
29.709=29.7 degrees
