Answer:
C=84
Step-by-step explanation:
Since you use 3 for pi. You plug the radius into the formula. C=2×3x14=84
The sum can be rewritten as y=4x, where y=f(x).
Now, we can rewrite the equation a x=y/4
Therefore, inv(f(x))=x/4
Trains depart after every 4 minutes.
Total time train takes to complete a circuit= 24 minutes
Evan sets off at 8:30 am, so he will be back at 8:54 am.
So time of trains coming in opposite direction:
8: 34 am
8:38 am
8:42 am
8:46 am
and 8:50 am
5 trains coming in opposite directions.
Now the trains started at 8:06 am from the stations are:
8:06 am
8:10 am
8:14 am
8:18 am
8:22 am
and 8:26 am.
So there are 6 trains started the circuit at 8:06 am.
Now total number of trains=6+5=11 trains
Answer: 11 trains will pass on complete circuit.
Answer:
Option A is correct.
Step-by-step explanation:
No of Balls in Basketball = 2
No of Balls in Dodge ball = 18
No of Balls in Soccer ball = 8
No of Balls in Tennis ball = 14

Ratio of Soccer balls to Tennis balls = 4 : 7
⇒ For every 4 Soccer ball, there are 7 Tennis ball.

Ratio of Basket ball to Dodge Ball = 1 : 9
⇒ For every 1 Basket ball, there are 9 Dodge balls.
Therefore, Option A is correct.
When 2 or more expressions are equivalent, that means they have the same outcome or result.
