If your playing a game and get 15 coins 30 minutes. How many coins will you get in 1 hour and 40 minutes?

krok68 [10]

Answer:

You would get 50 coins in that time.

Step-by-step explanation:

To find this, we first need to find the unit rate. We can get that by dividing the amount of coins by the amount of time.

15 coins/ 30 mins = .5 coins per minute.

Now, we have 100 minutes in the second part of the problem, so we multiply the rate by that amount of time.

.5 coins per min * 100 mins = 50 coins

ElenaW [278]

Answer:

a) In the first season, there were 25.450 million viewers.

b) In the fourth season, the number of viewers was 11.950 million.

Step-by-step explanation:

Hi there!

The average number of viewers in season t is given by the following function:

$f(t) = 32.744 e^{-0.252t}$

a) To obtain the average number of viewers in season 1, we have to evaluate the function at t = 1:

$f(1) = 32.744e^{-0.252 (1)} = 25.450$

In the first season, there were 25.450 million viewers.

b) Now we have to evaluate the function at t = 4:

$f(4) = 32.744e^{-0.252(4)} = 11.950$

In the fourth season, the number of viewers was 11.950 million.
