Answer:

  π/10 in/s ≈ 0.314 in/s

Step-by-step explanation:

The circumference of the circle it traverses is given by the formula ...

  C = 2πr

Substituting the given radius, we find the distance traveled in 60 seconds to be ...

  C = 2π(3 in) = 6π in

Then the linear speed is ...

  speed = distance/time = (6π in)/(60 s) = π/10 in/s

Just 16 not the words below​
alekssr [168]

Answer:

Table F

Step-by-step explanation:

The equation is C = 0.75t. The variable c is for cost and t is for tickets. When we use substitution to solve the equation, we see that table F correctly represents the situation. In simpler terms, the equation is asking us to mutliply the cost PER ticket by the number of tickets.

0.75 * 1 = 0.75

0.75 * 2 = 1.50

0.75 * 3 = 2.25

0.75 * 4 = 3

And so on. As we can see, the only table that shows these values is in fact table F.

Hope this helps!

Answer:

m = 60

Step-by-step explanation:

The context is very important, the 'm' represents the minutes late the parents are and from this we can eliminate some options :

- The last one because then a parent would drop their child off earlier

- The first one and the third one because it is too long
